16-7-2024 ROTTERDAM ZOO, NETHERLANDS - MEERKAT (Suricata suricatta)

The meerkat (Suricata suricatta) or suricate is a small mongoose found in southern Africa. It is characterised by a broad head, large eyes, a pointed snout, long legs, a thin tapering tail, and a brindled coat pattern. The head-and-body length is around 24–35 cm (9.4–13.8 in), and the weight is typically between 0.62 and 0.97 kg (1.4 and 2.1 lb). The coat is light grey to yellowish-brown with alternate, poorly-defined light and dark bands on the back. Meerkats have foreclaws adapted for digging and have the ability to thermoregulate to survive in their harsh, dry habitat. Three subspecies are recognised.

Meerkats are highly social, and form packs of two to 30 individuals each that occupy home ranges around 5 km2 (1.9 sq mi) in area. There is a social hierarchy—generally dominant individuals in a pack breed and produce offspring, and the nonbreeding, subordinate members provide altruistic care to the pups. Breeding occurs around the year, with peaks during heavy rainfall; after a gestation of 60 to 70 days, a litter of three to seven pups is born.

They live in rock crevices in stony, often calcareous areas, and in large burrow systems in plains. The burrow systems, typically 5 m (16 ft) in diameter with around 15 openings, are large underground networks consisting of two to three levels of tunnels. These tunnels are around 7.5 cm (3.0 in) high at the top and wider below, and extend up to 1.5 m (4 ft 11 in) into the ground. Burrows have moderated internal temperatures and provide a comfortable microclimate that protects meerkats in harsh weather and at extreme temperatures.

Meerkats are active during the day, mostly in the early morning and late afternoon; they remain continually alert and retreat to burrows when sensing danger. They use a broad variety of calls to communicate among one another for different purposes, for example to raise an alarm on sighting a predator. Primarily insectivorous, meerkats feed heavily on beetles and lepidopterans, arthropods, amphibians, small birds, reptiles, and plant material in their diet.

Commonly living in arid, open habitats with little woody vegetation, meerkats occur in southwestern Botswana, western and southern Namibia, and northern and western South Africa; the range barely extends into southwestern Angola. With no significant threats to the population, the meerkat is listed as Least Concern on theIUCN Red List. Meerkats are widely depicted in television, movies and other media.

Encounters between members of different packs are highly aggressive, leading to severe injuries and often deaths; 19% of meerkats die by conspecific violence, which is the highest recorded percentage among mammals. Females, often the heaviest ones, try to achieve dominance over the rest in many ways such as fierce competition or taking over from the leader of the pack. A study showed that females who grew faster were more likely to assert dominance, though males did not show such a trend. Males seeking dominance over groups tend to scent mark extensively and are not submissive; they often drive out older males in a group and take over the pack themselves. Subordinate individuals face difficulties in breeding successfully; for instance, dominant females often kill the litters of subordinate ones. As such, subordinate individuals might disperse to other packs to find mates during the breeding season.

 Some subordinate meerkats will even kill the pups of dominant members in order to improve their own offspring's position. It can take days for emigrants to secure entry into other packs, and they often face aversion from the members. Males typically succeed in joining existing groups; they often inspect other packs and their burrow systems in search of breeding opportunities. Many often team up in 'coalitions' for as long as two months and travel nearly 5 km (3.1 mi) a day on twisted paths. Dispersal appears to be less common in females, possibly because continuing to stay within a pack can eventually win them dominance over other members. Dispersed females travel longer than coalitions, and tend to start groups of their own or join other similar females; they aim for groups of emigrant males or those without a breeding female. Subordinate females, unlike subordinate males, might be ousted from their packs, especially in the latter part of the dominant female's pregnancy, though they may be allowed to return after the birth of the pups.

16-7-2024 ROTTERDAM ZOO, NETHERLANDS - AFRICAN SPURRED TORTOISE (Centrochelys sulcata)

The African spurred tortoise (Centrochelys sulcata), also called the sulcata tortoise, is an endangered species of tortoise inhabiting the southern edge of the Sahara Desert, the Sahel, in Africa. It is the largest mainland species of tortoise in Africa, and the third-largest in the world, after the Galapagos tortoise and Aldabra giant tortoise. It is the only living species in its genus, Centrochelys.

The African spurred tortoise is native to the Sahara Desert and the Sahel, a transitional ecoregion of semiarid grasslands, savannas, and thorn shrublands found in the countries of Burkina Faso, the Central African Republic, Chad, Eritrea, Ethiopia, Mali, Mauritania, Nigeria, Senegal, Saudi Arabia, Sudan, Yemen and possibly in Somalia, Algeria, Benin, and Cameroon. It is possibly extirpated from Djibouti and Togo. They are found on hills, stable dunes, and flat areas with shrubs and high grass. They also like to settle in areas with interrupted streams or rivers. In these arid regions, the tortoise excavates burrows in the ground to get to areas with higher moisture levels, and spends the hottest part of the day in these burrows. This is known as aestivation. In the wild, they may burrow very deep, up to 15 m deep and 30 m long. Plants such as grasses and succulents grow around their burrows if kept moist, and in nature they continue to grow for the tortoise to eat if the soil is replenished with its feces. Sulcata tortoises found in the Sudanese part of their range may reach significantly greater size at maturity than those found in other regions.

16-7-2024 ROTTERDAM ZOO, NETHERLANDS - WHITE BACKED VULTURE (Gyps africanus)

The white-backed vulture (Gyps africanus) is an Old World vulture in the family Accipitridae, which also includes eagles, kites, buzzards and hawks. It is the most common vulture species in the continent of Africa.

The white-backed vulture is a typical vulture, with only down feathers on the head and neck, very broad wings and short tail feathers. It has a white neck ruff. The adult's whitish back contrasts with the otherwise dark plumage. Juveniles are largely dark. This is a medium-sized vulture; its body mass is 4.2 to 7.2 kg (9.3–15.9 lb), it is 78 to 98 cm (31 to 39 in) long and has a 1.96 to 2.25 m (6 ft 5 in to 7 ft 5 in) wingspan.

The white-backed vulture occurs from Senegal, Gambia and Mali in the west, throughout the Sahel region to Ethiopia and Somalia in the east, through East Africa into Mozambique, Zimbabwe, Botswana, Namibia and South Africa in the south. It is the most widespread and common vulture in Africa with an estimated range of 24,300,000 km2 (9,400,000 sq mi), but has undergone rapid population declines in recent years.

The white-backed vulture, like many African vultures, has suffered a rapid decline. When it was first assessed in 1988 it was classified as a Least concern species owing to a large range and population. It was reassessed from a Least Concern to Near Threatened species in the 2007 IUCN Red List after the beginnings of a major decline were noticed. In 2012, more information was available about population trends, and the estimates suggested that within the next three generations the white-backed vulture would decrease by 50%. Consequently it was added to the list of Endangered species. In October 2015, it was further uplisted to Critically Endangered because the decline had reach a magnitude that puts the vulture at an extreme risk of extinction.

26-7-2024 DUNMORE EAST, IRELAND - EUROPEAN HERRING GULL (JUVENILE) (Larus argentatus)

Herring Gulls are large, noisy gulls found throughout the year around our coasts and inland around rubbish tips, fields, large reservoirs and lakes, especially during winter. Adults have light grey backs, white under parts, and black wing tips with white 'mirrors'. Their legs are pink with webbed feet and they have heavy, slightly curved bills marked with a red spot. Young birds are mottled brown. This species is on the Red List due to ongoing population declines and wintering population declines.

Herring Gulls are large gulls with hefty bills and robust bodies. In flight, they look barrel-chested and broad-winged compared to smaller species such as Ring-billed Gulls.

Adults have light-gray backs, black wingtips, and white heads and underparts. In winter, dusky streaks mark their heads. Herring Gulls take four years to reach adult plumage. Juveniles are mottled brown; second-year birds are brown but show gray on the back. Third-years have more gray on the back and more white on the head and underparts. The legs are dull pink at all ages.

Herring Gulls patrol shorelines and open ocean, picking scraps off the surface. Rallying around fishing boats or refuse dumps, they are loud and competitive scavengers, happy to snatch another bird's meal. They spend much of their time perched near food sources, often in congregations of gulls.

Herring Gulls patrol shorelines and open ocean, picking scraps off the surface. Rallying around fishing boats or refuse dumps, they are loud and competitive scavengers, happy to snatch another bird's meal. They spend much of their time perched near food sources, often in congregations of gulls.

Herring Gulls vary considerably across the Northern Hemisphere, and this combined with their tendency to hybridize with other gull species causes headaches in both taxonomy and identification. By sight, the different types of Herring Gulls are difficult to distinguish, and only the American Herring Gull (Larus argentatus smithsonianus) is likely to be seen in North America. European Herring Gulls (L . a. argentatus) and Yellow-legged Gulls (Larus michahellis, recently designated a separate species) are very rare visitors to eastern North America. The Vega Gull (L. a. vegae), a subspecies with a darker gray back, breeds in northwest Alaska and northeast Asia, but is very rare in the rest of North America.

26-7-2024 DUNMORE EAST, IRELAND - EUROPEAN HERRING GULL (Larus marinus)

The European herring gull (Larus argentatus) is a large gull, up to 66 cm (26 in) long. It breeds throughout the northern and western coasts of Europe. Some European herring gulls, especially those resident in colder areas, migrate further south in winter, but many are permanent residents, such as in Ireland, Britain, Iceland, or on the North Sea shores. They have a varied diet, including fish, crustaceans, as well as some plants, and are also scavengers, consuming carrion and food left by or stolen from humans.

European herring gull flocks have a loose pecking order, based on size, aggressiveness, and physical strength. Adult males are usually dominant over females and juveniles in feeding and boundary disputes, while adult females are typically dominant when selecting their nesting sites.

The European herring gull has long been believed to have extremely keen vision in daylight and night vision equal or superior to that of humans; however, this species is also capable of seeing ultraviolet light. This gull also appears to have excellent hearing and a sense of taste that is particularly responsive to salt and acidity.

Parasites of European herring gulls include the fluke Microphallus piriformes.

Herring gulls breed in much of north-western Europe, including Iceland, the United Kingdom, Ireland and France. Since 2009, herring gulls in the United Kingdom have been on the red list of birds of conservation concern, including County Durham.

They have been recorded from all the coasts of Europe including the Mediterranean and occasionally inland. Vagrants have been recorded in Israel, Cyprus and Turkey.

Birds in France are mainly resident, but northern populations migrate in winter, generally to the coasts of north-western Europe.

26-7-2024 DUNMORE EAST, IRELAND - SIX SPOT BURNET (Zygaena filipendulae)

The six-spot burnet (Zygaena filipendulae) is a day-flying moth of the family Zygaenidae.

Zygaena filipendulae is a common species throughout Europe, except the Atlantic coast of the Iberian Peninsula, northern Scandinavia and the Great Russian North. It is also present in Asia, from Anatolia through the Caucasus to Syria and Lebanon.

This species can be found in meadows, woodland clearings, sea-cliffs and area rich in grasses and flowers, up to 2,000 m altitude.

Zygaena filipendulae has a wingspan of 30–40 mm (1.2–1.6 in). The sexes are similar. The fore wings are dark metallic green with six vivid red spots (sometimes the spots are merged causing possible confusion with other species such as the five-spot burnet. Occasionally, the spots are yellow or even black. The hind wings are red with a blackish fringe. The larva is plump and hairy with variable markings, usually pale green with rows of black spots.

It is an aposematic moth because it is distinguished by its colors as toxic to predators like birds and lizards. If attacked it emits a liquid containing cyanide.

The adults fly on hot, sunny days from June to August, and are attracted to a wide variety of flowers such as knapweed and scabious, as well as the larval food plants bird's foot trefoil, Coronilla and clover.

The species overwinters as a larva. The larva pupates in early summer in a papery cocoon attached to a grass stem.

26-7-2024 DUNMORE EAST, IRELAND - PERENNIAL SOW THISTLE (Sonchus arvensis)

Sonchus arvensis, the field milk thistle, field sowthistle, perennial sow-thistle, corn sow thistle, dindle, gutweed, swine thistle, or tree sow thistle, is a species of flowering plant in the family Asteraceae. S. arvensis often occurs in annual crop fields and may cause substantial yield losses.

The plant grows up to 1.5 metres (4 ft 11 in) in height,: 744  with leaves 10–35 cm (4–13+3⁄4 in) long and 4–14 cm (1+1⁄2–5+1⁄2 in) wide.[7] It produces conspicuous yellow flowerheads about 3–5 cm (1+1⁄4–2 in) wide, which are visited by various types of insects—especially hoverflies of the genus Eristalis.

Sonchus arvensis is native to Eurasia, where it is widespread across most of the continent. It has also become naturalized in many other regions, and is considered an invasive noxious weed in some places, such as North America (including Prince Edward Island), Russia, New Zealand, and Australia.

It grows in areas such as pastures, roadsides, bushlands and the shorelines of lakes, rivers and sea coast.

A study conducted in 2003 has shown that with future global atmospheric carbon levels, S. arvensis shows increased growth with increased atmospheric carbon which could potentially expand its range and outcompete native species.  

26-7-2024 DUNMORE EAST, IRELAND - WILD CARROT (Daucus carota)

Daucus carota, whose common names include wild carrot, European wild carrot, bird's nest, bishop's lace, and Queen Anne's lace (North America), is a flowering plant in the family Apiaceae. It is native to temperate regions of the Old World and was naturalized in the New World.

Domesticated carrots are cultivars of a subspecies, Daucus carota subsp. sativus.

The wild carrot is a herbaceous, somewhat variable biennial plant that grows between 30 and 120 cm (1 and 4 ft) tall, and is roughly hairy, with a stiff, solid stem. The leaves are tripinnate, finely divided and lacy, and overall triangular in shape. The leaves are 5–15 cm (2–6 in) long, bristly and alternate in a pinnate pattern that separates into thin segments. The flowers are small and dull white, clustered in flat, dense umbels. The umbels are terminal and about 8–15 cm (3–6 in) wide. They may be pink in bud and may have a reddish or purple flower (the "ruby") in the centre of the umbel. The lower bracts are three-forked or pinnate, which distinguishes the plant from other white-flowered umbellifers. As the seeds develop, the umbel curls up at the edges, becomes more congested, and develops a concave surface. The fruits are small, dry, bumpy, oval and flattened, with short styles and hooked spines, as well as protective hairs surrounding it. The fruit has two mericarps, or bicarpellate. The endosperm of the fruit grows before the embryo. The dried umbels detach from the plant, becoming tumbleweeds. The function of the tiny red flower, coloured by anthocyanin, is to attract insects. The flowers bloom from May to September.

26-7-2024 DUNMORE EAST, IRELAND - NORTHERN FULMAR (Fulmarus glacialis)

The northern fulmar (Fulmarus glacialis), fulmar, or Arctic fulmar is a highly abundant seabird found primarily in subarctic regions of the North Atlantic and North Pacific oceans. There has been one confirmed sighting in the Southern Hemisphere, with a single bird seen south of New Zealand. Fulmars come in one of two color morphs: a light one, with white head and body and gray wings and tail, and a dark one, which is uniformly gray. Though similar in appearance to gulls, fulmars are in fact members of the family Procellariidae, which include petrels and shearwaters.

The northern fulmar and its sister species, the southern fulmar (Fulmarus glacialoides), are the extant members of the genus Fulmarus. The fulmars are in turn a member of the order Procellariiformes, and they all share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns; however, nostrils on albatrosses are on the sides of the bill, as opposed to the rest of the order, including fulmars, which have nostrils on top of the upper bill. The bills of Procellariiformes are also unique in that they are split into between seven and nine horny plates. One of these plates makes up the hooked portion of the upper bill, called the maxillary unguis. They produce a stomach oil made up of wax esters and triglycerides that is stored in the proventriculus. This can be sprayed out of their mouths as a defense against predators from a very early age, and as an energy rich food source for chicks and for the adults during their long flights. It will mat the plumage of avian predators, and can lead to their death. Finally, they also have a salt gland that is situated above the nasal passage that helps desalinate their bodies, due to the high amount of ocean water that they imbibe. This gland excretes a high saline solution from their nose.

26-7-2024 DUNMORE EAST, IRELAND - HARDY FUSCHIA (Fuchsia magellanica)

Fuchsia magellanica – commonly known as the hummingbird fuchsia, hardy fuchsia or chilco (from Mapudungun: chillko "watery" – is a species of flowering plant in the evening primrose family Onagraceae, native to the lower Southern Cone of southern South America.

They arrived in England in the late 18th century. According to tradition, the English gardener James Lee discovered them on the windowsill of a seaman's house and bought them for a considerable sum. As early as 1793 Lee is said to have sold a large number of pieces that he had pulled from this one copy. Fuchsia magellanica, and its cultivars and hybrids, are widely cultivated by plant nurseries and gardeners as ornamental plants. They are grown in temperate and subtropical gardens and conservatories, in containers on patios, balcony|balconies, and indoors. They prefer a sunny position.

The plants are quite cold-hardy compared to other species from more tropical climates, being deciduous where frosts are light, and only top die back in hard frosts (with mulching). The profuse drooping flowers are a nectar source attractive to hummingbirds.

This species, and hybrids using it as parent stock, are very susceptible to the fuchsia gall mite, Aculops fuchsiae, a serious disfiguring pest that was first accidentally spread from its native Brazil to the West Coast of the United States in 1980. It has more recently made appearances in France (2003), the Channel Islands (2006) and the United Kingdom (2007). Fortunately the fuchsia gall mite does not readily survive temperatures below 40 °F (4 °C), and there are effective treatments and strategies.

It has been used in traditional remedies as a diuretic and antipyretic.

26-7-2024 DUNMORE EAST, IRELAND - GARDEN MONBRETIA (Crocosmia × crocosmiiflora)

Crocosmia × crocosmiiflora, montbretia, is a garden hybrid of C. aurea and C. pottsii,[a] first bred in 1880 in France by Victor Lemoine. The basionym of the hybrid is Montbretia crocosmiiflora Lemoine. In 1932 it was reclassified as C. × crocosmiiflora (Lemoine) N.E.Br., but the common name "montbretia" is still often found in horticultural literature, and is commonly used in the British Isles for orange-flowered cultivars that have naturalised, while "crocosmia" is reserved for less aggressive red-flowered cultivars.

Crocosmia × crocosmiiflora grows to 90 cm high, with long sword-shaped leaves, shorter than the flowering stem and arising from the plant base, ribbed and up to 20mm wide.[1] The base is a corm, a swollen underground stem lasting one year. The flowers are up to 5 cm long and coloured deep orange.

In the United States, Crocosmia × crocosmiiflora is considered suitable for planting in hardiness zones 5–9, but in more northerly locations it can be planted in the spring and the corms dug out in the fall. The corms should be planted in a well-drained garden soil in full sun to partial shade. The hybrid will set viable seed that can be grown as soon as ripe, but as a hybrid it will not breed true to colour. In Belfast, Northern Ireland, it is recorded as well-established in a wide range of locations.

26-7-2024 DUNMORE EAST, IRELAND - EURASIAN KESTREL (Falco tinnunculus)

The common kestrel (Falco tinnunculus), also known as the European kestrel, Eurasian kestrel or Old World kestrel, is a species of predatory bird belonging to the kestrel group of the falcon family Falconidae. In the United Kingdom, where no other kestrel species commonly occurs, it is generally just called "kestrel".

This species occurs over a large native range. It is widespread in Europe, Asia and Africa, as well as occasionally reaching the east coast of North America. It has colonized a few oceanic islands, but vagrant individuals are generally rare; in the whole of Micronesia for example, the species was only recorded twice each on Guam and Saipan in the Marianas.

In the cool-temperate parts of its range, the common kestrel migrates south in winter; otherwise it is sedentary, though juveniles may wander around in search for a good place to settle down as they become mature. It is a diurnal animal of the lowlands and prefers open habitat such as fields, heaths, shrubland and marshland. It does not require woodland to be present as long as there are alternative perching and nesting sites like rocks or buildings. It will thrive in treeless steppe where there are abundant herbaceous plants and shrubs to support a population of prey animals. The common kestrel readily adapts to human settlement, as long as sufficient swathes of vegetation are available, and may even be found in wetlands, moorlands and arid savanna. It is found from the sea to the lower mountain ranges, reaching elevations up to 4,500 m (14,800 ft) ASL in the hottest tropical parts of its range but only to about 1,750 m (5,740 ft) in the subtropical climate of the Himalayan foothills.

25-7-2024 COBH, IRELAND - BUFF TAILED BUMBLE BEE (Bombus terrestris),

Did you know that:

- one spoonful of honey is enough to keep a person alive for 24 hours

- one of the first coins in the world featured a bee symbol

- honey contains live enzymes. The metal spoon kills these enzymes. The best way to consume honey is with a wooden spoon, if not, you can use a plastic one.

- honey contains a substance that helps the brain function.

- honey is one of the few foods on earth that alone can sustain human life.

- bees saved people from starvation in Africa.

- propolis produced by bees is one of nature's most powerful antibiotics.

- honey has no expiration date.

- the bodies of the world's greatest emperors were buried in golden coffins and then covered with honey to prevent them from rotting.

- the term "honeymoon" comes from the fact that the young couple consumed honey for fertility purposes after marriage.

- a bee lives less than 40 days, visits at least 1,000 flowers and produces less than a teaspoon of honey, but for her it is the work of a lifetime.

25-7-2024 COBH, IRELAND - PURPLE VEINED GERANIUM (Geranium wallichianum)

Geranium wallichianum is a species of hardy flowering herbaceous perennial plant in the genus Geranium, family Geraniaceae. It is native to the Himalayas. It grows to 60 cm (24 in) tall and broad, with hairy toothed leaves and masses of bright blue flowers in summer. It is suitable for cultivation in temperate climates, in the front of the border.

The specific epithet wallichianum honours the Danish plant hunter Dr Nathaniel Wallich (1786-1854).

Various cultivars have been selected, including Rozanne='Gerwat', which has gained the Royal Horticultural Society's Award of Garden Merit. It is larger and more floriferous than the species.

16-7-2024 ROTTERDAM ZOO, NETHERLANDS - HELMETED GUINEA FOWL (Numida meleagris)

The helmeted guineafowl (Numida meleagris) is the best known of the guineafowl bird family, Numididae, and the only member of the genus Numida. It is native to Africa, mainly south of the Sahara, and has been widely introduced, as a domesticated species, into the West Indies, North America, Colombia, Brazil, Australia and Europe.

The helmeted guineafowl is a large, 53 to 58 cm (21 to 23 in) bird with a round body and small head. They weigh about 1.3 kg (2.9 lb). The body plumage is gray-black speckled with white. Like other guineafowl, this species has an unfeathered head, which in this species is decorated with a dull yellow or reddish bony knob, and bare skin with red, blue, or black hues. The wings are short and rounded, and the tail is likewise short. Various subspecies are proposed, differences in appearance being mostly a large variation in shape, size, and colour of the casque and facial wattles.

This is a gregarious species, forming flocks outside the breeding season typically of about 25 birds that also roost communally. Guineafowl are particularly well-suited to consuming massive quantities of ticks, which might otherwise spread Lyme disease. These birds are terrestrial, and prone to run rather than fly when alarmed. Like most gallinaceous birds, they have a short-lived, explosive flight and rely on gliding to cover extended distances. Helmeted guineafowl can walk 10 km and more in a day. Their bodies are well-suited for running and they are remarkably successful in maintaining dynamic stability over rough terrain at speed.[9] They make loud harsh calls when disturbed.

25-7-2024 COBH, IRELAND - BLACK HEADED GULL (Chroicocephalus ridibundus)

The black-headed gull (Chroicocephalus ridibundus) is a small gull that breeds in much of the Palearctic including Europe and also in coastal eastern Canada. Most of the population is migratory and winters further south, but some birds reside in the milder westernmost areas of Europe. The species also occurs in smaller numbers in northeastern North America, where it was formerly known as the common black-headed gull.

The black-headed gull was previously placed in the genus Larus but in agreement with the NACC and SACC, and based on Pons et al. (Pons, J.-M.., A. Hassanin, and P.-A. Crochet. 2005. "Phylogenetic relationships within the Laridae" (Charadriiformes: Aves) inferred from mitochondrial markers, "Molecular Phylogenetics and Evolution" 37: 686-699) and earlier references, extensive changes to the taxonomy of gulls was undertaken and many species of gull were removed from the genus Larus, including the black-headed gull 

The black-headed gull displays a variety of compelling behaviours and adaptations. Some of these include removing eggshells from the nest after hatching, begging co-ordination between siblings, differences between sexes, conspecific brood parasitism, and extra-pair paternity. They are an overwintering species, found in a variety of different habitats.

This gull is 37–44 cm (14+1⁄2–17+1⁄2 in) long with a 94–110 cm (37–43+1⁄2 in) wingspan and weighs 190–400 g (6+3⁄4–14+1⁄8 oz).

In flight, the white leading edge to the wing is a good field mark. The summer adult has a chocolate-brown head (not black, although does look black from a distance), pale grey body, black tips to the primary wing feathers, and red bill and legs. The hood is lost in winter, leaving just two dark spots. Immature birds have a mottled pattern of brown spots over most of the body,[4] and a black band on the tail. There is no difference in plumage between the sexes.

It breeds in colonies in large reed beds or marshes, or on islands in lakes, nesting on the ground. Like most gulls, it is highly gregarious in winter, both when feeding or in evening roosts. It is not a pelagic species and is rarely seen at sea far from coasts.

The black-headed gull is a bold and opportunistic feeder. It eats insects, fish, seeds, worms, scraps, and carrion in towns, or invertebrates in ploughed fields with equal relish. It is a noisy species, especially in colonies, with a familiar "kree-ar" call. Its scientific name means laughing gull.

This species takes two years to reach maturity. First-year birds have a black terminal tail band, more dark areas in the wings, and, in summer, a less fully developed dark hood. Like most gulls, black-headed gulls are long-lived birds, with a maximum age of at least 32.9 years recorded in the wild, in addition to an anecdote now believed of dubious authenticity regarding a 63-year-old bird.

Black-headed gulls can be found over much of Europe. It is also found in across the Palearctic to Japan and east China. Small numbers also breed in northeastern Canada and can be seen in winter in northeast North America as far south as Virginia, often with the similar-looking Bonaparte's Gull and also in some Caribbean islands. Recorded as a very rare transient gull in the Carolina coast. 

25-7-2024 COBH, IRELAND - EURASIAN JACKDAW (Corvus monedula)

The western jackdaw (Coloeus monedula), also known as the Eurasian jackdaw, the European jackdaw, or simply the jackdaw, is a passerine bird in the crow family. Found across Europe, western Asia and North Africa; it is mostly resident, although northern and eastern populations migrate south in the winter. Four subspecies are recognised, which differ mainly in the colouration of the plumage on the head and nape. Linnaeus first described it formally, giving it the name Corvus monedula. The common name derives from the word jack, denoting "small", and daw, a less common synonym for "jackdaw", and the native English name for the bird.

Measuring 34–39 centimetres (13–15 in) in length, the western jackdaw is a black-plumaged bird with a grey nape and distinctive pale-grey irises. It is gregarious and vocal, living in small groups with a complex social structure in farmland, open woodland, on coastal cliffs, and in urban settings. Like its relatives, jackdaws are intelligent birds, and have been observed using tools. An omnivorous and opportunistic feeder, it eats a wide variety of plant material and invertebrates, as well as food waste from urban areas. Western jackdaws are monogamous and build simple nests of sticks in cavities in trees, cliffs, or buildings. About five pale blue or blue-green eggs with brown speckles are laid and incubated by the female. The young fledge in four to five weeks.

The western jackdaw is found from Northwest Africa through all of Europe, except for the subarctic north, and eastwards through central Asia to the eastern Himalayas and Lake Baikal. To the east, it occurs throughout Turkey, the Caucasus, Iran, Iraq, Afghanistan, Pakistan, and northwestern India. However, it is regionally extinct in Malta and Tunisia. The range is vast, with an estimated global extent between 1 and 10 million square kilometres (0.4–4 million square miles). It has a large global population, with an estimated 15.6 to 45 million individuals in Europe alone. Censuses of bird populations in marginal uplands in Great Britain show that western jackdaws greatly increased in numbers between the 1970s and 2010, although this increase may be related to recovery from previous periods when they were regarded as pests. The UK population was estimated at 2.5 million individuals in 1998, up from 780,000 in 1970.

25-7-2024 COBH, IRELAND - SEASIDE DAISY (Erigeron glaucus)

Erigeron glaucus is a species of flowering plant in the family Asteraceae known by the common name seaside fleabane, beach aster, or seaside daisy. It is native to the West Coast of the United States.

E. glaucus is a perennial daisy reaching heights between 5 and 40 centimetres (2 and 15+1⁄2 inches) with branching, nodding stems which may be glandular and hairy to hairless. It grows from a stout rhizome and produces thick, firm, rounded to spoon-shaped leaves, sometimes with a few teeth along the edges, each 2–13 cm (3⁄4–5 in) long. From April to August, its stems bear inflorescences of 1–15 flower heads which vary in size from about 1 to 6.5 cm (1⁄2 to 2+1⁄2 in) wide. The centers contain golden yellow disc florets and the edges are fringed with about 100 ray florets which may be long or quite short, and are shades of deep blue and purple to nearly white. The fruit is seed-like with many bristles at the tip.

Unusual for its genus (but not for plants near the coast), the plant is somewhat succulent.

The wildflower is native to the coastline of Oregon and California where it grows on beaches, coastal bluffs and dunes. While typical habitats include coastal bluffs, one highly specialised plant association is found within the two Cupressus macrocarpa dominant forests in Monterey County, California.

25-7-2024 COBH, IRELAND - ROOK (Corvus frugilegus)

The rook (Corvus frugilegus) is a member of the family Corvidae in the passerine order of birds. It is found in the Palearctic, its range extending from Scandinavia and western Europe to eastern Siberia. It is a large, gregarious, black-feathered bird, distinguished from similar species by the whitish featherless area on the face. Rooks nest collectively in the tops of tall trees, often close to farms or villages; the groups of nests are known as rookeries.

Rooks are mainly resident birds, but the northernmost populations may migrate southwards to avoid the harshest winter conditions. The birds form flocks in winter, often in the company of other Corvus species or jackdaws. They return to their rookeries, and breeding takes place in spring. They forage on arable land and pasture, probing the ground with their strong bills and feeding largely on grubs and soil-based invertebrates, but they also consume cereals and other plant material. Historically, farmers have accused the birds of damaging their crops and have made efforts to drive them away or kill them. Like other corvids, they are intelligent birds with complex behavioural traits and an ability to solve simple problems. 

The rook is a fairly large bird, at 280 to 340 g (9.9 to 12.0 oz) adult weight, 44 to 46 cm (17 to 18 in) in length and 81 to 99 cm (32 to 39 in) wingspan. It has black feathers that often show a blue or bluish-purple sheen in bright sunlight. The feathers on the head, neck and shoulders are particularly dense and silky. The legs and feet are generally black, the bill grey-black and the iris dark brown. In adults, a bare area of whitish skin in front of the eye and around the base of the bill is distinctive, and enables the rook to be distinguished from other members of the crow family. This bare patch gives the false impression that the bill is longer than it is and the head more domed. The feathering around the legs also appears shaggier and laxer than the similarly sized carrion crow, the only other member of its genus with which the rook is likely to be confused. Additionally, when seen in flight, the wings of a rook are proportionally longer and narrower than those of the carrion crow. The average lifespan is six years.

The juvenile plumage is black with a slight greenish gloss, except for the hind neck, back and underparts, which are brownish-black. The juvenile is superficially similar to a young crow because it lacks the bare patch at the base of the bill, but it has a thinner beak and loses the facial feathers after about six months.

Western rooks are resident in the British Isles and much of north and central Europe but vagrant to Iceland and parts of Scandinavia, where they typically live south of 60° latitude. They are found in habitats that common ravens dislike, choosing open agricultural areas with pasture or arable land, as long as there are suitable tall trees for breeding. They generally avoid forests, swamps, marshes, heaths and moorland. They are in general lowland birds, with most rookeries found below 120 m (400 ft), but where suitable feeding habitat exists, they may breed at 300 m (1,000 ft) or even higher. Rooks are often associated with human settlements, nesting near farms, villages and open towns, but not in large, heavily built-up areas. The eastern subspecies in Asia differs in being slightly smaller on average, and having a somewhat more fully feathered face. In the north of its range the species has a tendency to move south during autumn, and more southern populations are apt to range sporadically.

 

The rook is a very social bird; in the evenings they gather in large flocks, often in thousands.

Rooks are highly gregarious birds and are generally seen in flocks of various sizes. Males and females pair-bond for life and pairs stay together within flocks. In the evening, the birds often congregate at their rookery before moving off to their chosen communal roosting site. Flocks increase in size in autumn with different groups amalgamating and birds congregating at dusk before roosting, often in very large numbers and in the company of jackdaws. Roosting usually takes place in woodland or plantations, but a small minority of birds may continue to roost at their rookery all winter, and adult males may roost collectively somewhere nearby. The birds move off promptly in the morning, dispersing for distances of up to 10 km (6 mi).

Large groups of rooks (in breeding colonies or night roost sites) can contribute to changes in soil properties. The amount of ornithogenic material in these soils is very high.

Foraging mostly takes place on the ground, with the birds striding about, or occasionally hopping, and probing the soil with their powerful beaks. Flight is direct, with regular wingbeats and little gliding while in purposeful flight; in contrast, the birds may glide more extensively when wheeling about in leisure flight near the rookery. In the autumn, flocks sometimes perform spectacular aerial group flights, including synchronised movements and individual antics such as dives, tumbles and rolls.

16-7-2024 ROTTERDAM ZOO, NETHERLANDS - AFRICAN GREY PARROT (Psittacus erithacus)

The grey parrot (Psittacus erithacus), also known as the Congo grey parrot, Congo African grey parrot or African grey parrot, is an Old World parrot in the family Psittacidae. The Timneh parrot (Psittacus timneh) once was identified as a subspecies of the grey parrot, but has since been elevated to a full species.

The grey parrot is medium-sized, predominantly grey and black-billed. Its typical weight is 400 g (14 oz), with an approximate length of 33 cm (13 in) and a wingspan of 46–52 cm (18–20+1⁄2 in). The head and wings are generally darker than the body. Head and body feathers have slight white edges; the tail feathers are red.

Due to selection by breeders, some grey parrots are partly or completely red. Both sexes appear similar. Juvenile colouration is similar to that of adults, but typically their eyes are dark grey to black, compared to adults' yellow irises around dark pupils, and their undertail coverts are tinged with grey. Adults weigh 418–526 g (14+3⁄4–18+1⁄2 oz).

Grey parrots may live for 40–60 years in captivity, although their mean lifespan in the wild appears to be shorter — approximately 23 years. They start breeding at an age of 3–5 years and lay 3-5 eggs per brood.

The grey parrot is native to equatorial Africa, including Angola, Cameroon, the Congo, Gabon, Ivory Coast, Ghana, Kenya, and Uganda. The species is found inside a range from Kenya to the eastern part of the Ivory Coast. Current estimates for the global population are uncertain and range from 630,000 to 13 million birds. Populations are decreasing worldwide. The species seems to favor dense forests, but can also be found at forest edges and in more open vegetation types, such as gallery and savanna forests.

A population study published in 2015 found that the species had been "virtually eliminated" from Ghana with numbers declining 90 to 99% since 1992. They were found in only 10 of 42 forested areas, and three roosts that once held 700–1200 birds each, now had only 18 in total. Local people mainly blamed the pet trade and the felling of timber for the decline.[16] Populations are thought to be stable in Cameroon. In the Congo, an estimated 15,000 are taken every year for the pet trade, from the eastern part of the country, although the annual quota is stated to be 5,000.

The Florida Fish and Wildlife Conservation Commission indicated they have spotted grey parrots escaped or been released into South Florida since at least 1984, but no evidence indicates that the population is breeding naturally.

16-7-2024 ROTTERDAM ZOO, NETHERLANDS - HOUSE SPARROW (MALE) (Passer domesticus)

The house sparrow (Passer domesticus) is a bird of the sparrow family Passeridae, found in most parts of the world. It is a small bird that has a typical length of 16 cm (6.3 in) and a mass of 24–39.5 g (0.85–1.39 oz). Females and young birds are coloured pale brown and grey, and males have brighter black, white, and brown markings. One of about 25 species in the genus Passer, the house sparrow is native to most of Europe, the Mediterranean Basin, and a large part of Asia. Its intentional or accidental introductions to many regions, including parts of Australasia, Africa, and the Americas, make it the most widely distributed wild bird.

The house sparrow is strongly associated with human habitation, and can live in urban or rural settings. Though found in widely varied habitats and climates, it typically avoids extensive woodlands, grasslands, polar regions, and hot, dry deserts far away from human development. For sustenance, the house sparrow routinely feeds at home and public bird feeding stations, but naturally feeds on the seeds of grains, flowering plants and weeds. However, it is an opportunistic, omnivorous eater, and commonly catches insects, their larvae, caterpillars, invertebrates and many other natural foods.

16-7-2024 ROTTERDAM ZOO, NETHERLANDS - SECRETARY BIRD (Sagittarius serpentarius),

The secretarybird or secretary bird (Sagittarius serpentarius) is a large bird of prey that is endemic to Africa. It is mostly terrestrial, spending most of its time on the ground, and is usually found in the open grasslands and savanna of the sub-Saharan region. John Frederick Miller described the species in 1779. A member of the order Accipitriformes, which also includes many other diurnal birds of prey such as eagles, hawks, kites, vultures, and harriers, it is placed in its own family, Sagittariidae.

The secretarybird is instantly recognizable as a very large bird with an eagle-like body on crane-like legs that give the bird a height of as much as 1.3 m (4 ft 3 in). The sexes are similar in appearance. Adults have a featherless red-orange face and predominantly grey plumage, with a flattened dark crest and black flight feathers and thighs.

Breeding can take place at any time of year but tends to be late in the dry season. The nest is built at the top of a thorny tree, and a clutch of one to three eggs is laid. In years with plentiful food all three young can survive to fledging. The secretarybird hunts and catches prey on the ground, often stomping on victims to kill them. Insects and small vertebrates make up its diet.

Although the secretarybird resides over a large range, the results of localised surveys suggest that the total population is experiencing a rapid decline, probably as a result of habitat destruction. The species is therefore classed as Endangered by the International Union for Conservation of Nature. The secretarybird appears on the coats of arms of Sudan and South Africa.

The secretarybird is endemic to sub-Saharan Africa and is generally non-migratory, though it may be locally nomadic as it follows rainfall and the resulting abundance of prey. Its range extends from Senegal to Somalia and south to Western Cape, South Africa.

The species is also found at a variety of elevations, from the coastal plains to the highlands. The secretarybird prefers open grasslands, savannas and shrubland (Karoo) rather than forests and dense shrubbery that may impede its cursorial existence. More specifically, it prefers areas with grass under 0.5 m (1 ft 8 in) high and avoids those with grass over 1 m (3 ft 3 in) high. It is rarer in grasslands in northern parts of its range that otherwise appear similar to areas in southern Africa where it is abundant, suggesting it may avoid hotter regions. It also avoids deserts.

24-7-2024 IRISH COAST, IRELAND - NORTHERN GANNET (Morus bassanus),

The northern gannet (Morus bassanus) is a seabird, the largest species of the gannet family, Sulidae. It is native to the coasts of the Atlantic Ocean, breeding in Western Europe and Northeastern North America. It is the largest seabird in the northern Atlantic. The sexes are similar in appearance. The adult northern gannet has a mainly white streamlined body with a long neck, and long and slender wings. It is 87–100 cm (34+1⁄2–39+1⁄2 in) long with a 170–180 cm (67–71 in) wingspan. The head and nape have a buff tinge that is more prominent in breeding season, and the wings are edged with dark brown-black feathers. The long, pointed bill is blue-grey, contrasting with black, bare skin around the mouth and eyes. Juveniles are mostly grey-brown, becoming increasingly white in the five years it takes them to reach maturity.

Nesting takes place in colonies on both sides of the North Atlantic, the largest of which are at Bass Rock (75,000 pairs as of 2014), St. Kilda (60,000 pairs as of 2013) and Ailsa Craig (33,000 pairs as of 2014) in Scotland, Grassholm in Wales, and Bonaventure Island (60,000 pairs in 2009) off the coast of Quebec. Its breeding range has extended northward and eastward, with colonies being established on Russia's Kola Peninsula in 1995 and Bear Island (the southernmost island of Svalbard), in 2011. Colonies are mostly located on offshore islands with cliffs, from which the birds can more easily launch into the air. The northern gannet undertakes seasonal migrations and catches fish (which are the mainstay of its diet) by making high-speed dives into the sea.

The northern gannet was previously hunted for food in certain parts of its range, and although that practice still continues in the Outer Hebrides of Scotland and the Faroe Islands, the bird faces few other natural or man-made threats.

Northern Gannets have excellent vision. They detect foraging gannets at great distances, enabling them to move quickly to reach prey. Their sharp eyes also allow them to detect prey underwater amid the reflected and refracted light where water and air meet.

Gannets are Scotland’s, and indeed Britain’s, largest seabird. The specific type found here is the northern gannet, identifiable by its bright white plumage, long neck and beak, and distinctive black wing tips. 

Gannets feed on a variety of fish at sea, and to catch these fish they have to dive (makes sense). But did you know that when these seabirds actually hit the surface of the water they can be travelling as fast as 60mph?! To do this they have specifically developed neck muscles and a spongy bone plate at the base of their bill to reduce the impact. They also have special membranes to guard their eyes.

15-7-2024 BLIJDORP, ROTTERDAM - CARRION CROW (Corvus corone)

The carrion crow (Corvus corone) is a passerine bird of the family Corvidae and the genus Corvus which is native to western Europe and the eastern Palearctic.

The plumage of the carrion crow is black with a green or purple sheen, much greener than the gloss of the rook (Corvus frugilegus). The bill, legs and feet are also black. It can be distinguished from the common raven by its size of around 48–52 centimetres (19–20 in) in length as compared to an average of 63 centimetres (25 inches) for ravens, and from the hooded crow by its black plumage. The carrion crow has a wingspan of 84–100 centimetres (33–39 in) and weighs 400–600 grams (14 oz – 1 lb 5 oz).

Juvenile carrion crows can be identified by their brownish plumage and blue eyes, both of which darken to black and brown as the crow grows older.

The rook is generally gregarious and the crow largely solitary, but rooks occasionally nest in isolated trees, and crows may feed with rooks; moreover, crows are often sociable in winter roosts. The most distinctive feature is the voice. The rook has a high-pitched kaaa, but the crow's guttural, slightly vibrant, deeper croaked kraa is distinct from any note of the rook.

The carrion crow is noisy, perching on a vantage point such as a building or the top of a tree and calling three or four times in quick succession, with a slight pause between each series of croaks. During each series of calls, a crow may perform an accompanying gesture, raising its shoulders and bowing its head and neck downwards with each caw. The wing-beats are slower, more deliberate than those of the rook.

Carrion crows can become tame near humans, and can often be found near areas of human activity or habitation including cities, moors, woodland, sea cliffs and farmland where they compete with other social birds such as gulls, other corvids, and ducks for food in parks and gardens. other species of corvid, carrion crows will actively harass predators and competitors that enter their territory or threaten them or their offspring, and will engage in group mobbing behaviour as a method to defend themselves.

Like all corvids, carrion crows are very intelligent. For example, they can discriminate between numerosities up to 30, flexibly switch between rules, and recognise human and crow faces. Given the difference in brain architecture in crows compared to primates, these abilities suggest that their intelligence is realised as a product of convergent evolution.
