19-3-2015 JURONG, SINGAPORE - EARED DOVE (Zenaida auriculata)

The eared dove (Zenaida auriculata) is a New World dove. It is a resident breeder throughout South America from Colombia to southern Argentina and Chile, and on the offshore islands from the Grenadines southwards. It may be a relatively recent colonist of Tobago and Trinidad. It appears to be partially migratory, its movements driven by food supplies.

It is a close relative of the North American mourning dove. With that species, the Socorro dove, and possibly the Galápagos dove, it forms a superspecies. The latter two are insular offshoots, the Socorro birds from ancestral mourning doves, and the Galápagos ones from more ancient stock.


Eared doves provide the last big-bag shooting experience in the world. More than 23 million of these doves are thought to be in the fields around Córdoba in northern Argentina, and recent estimates put the figure in the 32-million range. Not uncommonly, a single gun can shoot 1000 birds in a day.

The scale of this wing-shooting recalls the numbers of passenger pigeons taken by North American gunners in the 1800s. That hunting pressure brought the passenger pigeon to rapid extinction, but the eared dove seems to be more resilient. Indeed, as with the passenger pigeons, eared dove populations in Argentina and Bolivia sometimes "darken the skies". Thus, populations on the sporting estates of Argentina seem to be holding their own, with the birds breeding four times a year and thriving on the vast areas of grain, some grown for their benefit, most of it on commercial farms, which are happy to support the dove shooting. Dozens of luxury lodges specialize in dove hunting, and the season extends all year long.

The eared doves around Córdoba do not migrate, and the enormous flocks are described as flying constantly between their roosting woods and the open fields. In the Córdoba region in Argentina, the eared doves are known as palomas doradas because of the shining feathers sometimes present in their plumage.

Further north, in Bolivia, around de Gran Chaco region, near the immense soy and sorghum plantations around Santa Cruz de la Sierra, the dove shooting is more seasonal, going from May to September, with large flocks arriving from Argentina to raid the grain crops. Locals attest that eared doves, which they call by the Guaraní name of totaky, were quite rare in the region just a few decades ago, a testimony not only to the resilience of the species, but also to the huge impact that the newly created large feeding grounds have on dove populations.

19-3-2015 SINGAPORE - VICTORIA CROWNED PIGEON (Goura cristata)

The Victoria crowned pigeon (Goura victoria) is a large, bluish-grey pigeon with elegant blue lace-like crests, maroon breast and red irises. It is part of a genus (Goura) of four unique, very large, ground-dwelling pigeons native to the New Guinea region. The bird may be easily recognized by the unique white tips on its crests and by its deep 'whooping' sounds made while calling. Its name commemorates the British monarch Queen Victoria.

The Victoria crowned pigeon is distributed in the lowland and swamp forests of northern New Guinea and surrounding islands. It usually occurs on areas that were former alluvial plains, including sago forests. Though typically found at or near sea level, occasionally birds of this species may venture up in the hills to an elevation up to about 3,000 feet.


19-3-2015 JURONG, SINGAPORE - LESSER WHISTLING DUCK (JUVENILE) (Dendrocygna javanica)


The lesser whistling duck (Dendrocygna javanica), also known as Indian whistling duck or lesser whistling teal, is a species of whistling duck that breeds in the Indian subcontinent and Southeast Asia. They are nocturnal feeders that during the day may be found in flocks around lakes and wet paddy fields. They can perch on trees and sometimes build their nest in the hollow of a tree. This brown and long-necked duck has broad wings that are visible in flight and produces a loud two-note wheezy call. It has a chestnut rump, differentiating it from its larger relative, the fulvous whistling duck, which has a creamy white rump.

19-3-2015 , SINGAPORE - HYMENOCALLIS SPECIOSA (Family Amaryllidaceae )

Hymenocallis speciosa, the green-tinge spiderlily, is a species of the genus Hymenocallis that is native to the Windward Islands in the eastern Caribbean. It is cultivated as an ornamental in some areas, and reportedly naturalized in Cuba and the Bahamas.

Hymenocallis speciosa is a bulb-forming perennial. Stipe can attain a height of up to 50 cm. Leaves are lanceolate, up to 50 cm long and 10 cm across, narrowing to a petiole below. One umbel can produce as many as 20 flowers. Flowers are white with a slight greenish tinge, the tepals reflexed (curling backwards) at flowering time. 

19-3-2015 JURONG, SINGAPORE - SPOTTED DOVE (Spilopelia chinensis)

This species was formerly included in the genus Streptopelia with other turtle-doves, but studies suggest that they differ from typical members of that genus. This dove is long tailed buff brown with a white-spotted black collar patch on the back and sides of the neck. The tail tips are white and the wing coverts have light buff spots.

There are considerable plumage variations across populations within its wide range. The species is found in light forests and gardens as well as in urban areas. They fly from the ground with an explosive flutter and will sometimes glide down to a perch. It is also called the mountain dove, pearl-necked dove, lace-necked dove, and spotted turtle-dove.

The spotted dove in its native range in Asia is found across a range of habitats including woodland, scrub, farmland and habitation. In India it tends to be found in the moister regions, with the laughing dove (S. senegalensis) appearing more frequently in drier areas. These doves are mostly found on the ground where they forage for seeds and grain or on low vegetation.

9-5-2021 MONTAVERNER, VALENCIA - LYTHRUM LOOSESTRIFE (Genus Lythrum)


Lythrum is a genus of 38 species of flowering plants native to the temperate world. Commonly known as loosestrife (a name they share with Lysimachia, which are not closely related), they are among 32 genera of the family Lythraceae.

They are herbaceous annuals or perennials. Typically they have square stems, narrow stalkless leaves, and spikes of star-shaped flowers in shades of purple, pink and white. They are especially associated with boggy areas, river banks and ponds, though in cultivation they often tolerate drier conditions. The species L. salicaria (purple loosestrife) and L. virgatum are found in cultivation.

19-3-2015 , SINGAPORE - PEACOCK FLOWER (Caesalpinia pulcherrima)


Caesalpinia pulcherrima is a species ofFlowering plant in the pea family Fabaceae, native to the tropics and subtropics of the Americas. It could be native to the West Indies, but its exact origin is unknown due to widespread cultivation. Common names for this species include poinciana, peacock flower, red bird of paradise, Mexican bird of paradise, dwarf poinciana, pride of Barbados, flos pavonis, and flamboyant-de-jardin. The Hawaiian name for this plant is ʻohai aliʻi.

It is a shrub growing to 3 m tall. In climates with few to no frosts, this plant will grow larger and is semievergreen. In Hawaii this plant is evergreen and grows over 5 m tall. Grown in climates with light to moderate freezing, plant will die back to the ground depending on cold, but will rebound in mid- to late spring. This species is more sensitive to cold than others. The leaves are bipinnate, 20–40 cm long, bearing three to 10 pairs of pinnae, each with six to 10 pairs of leaflets 15–25 mm long and 10–15 mm broad. The flowers are borne in racemes up to 20 cm long, each flower with five yellow, orange, or red petals. The fruit is a pod 6–12 cm long.

29-1-2024 XERACO CAMPO, VALENCIA - EURASIAN GREAT CORMORANT (Phalacrocorax carbo)


Great cormorants are one of the most widespread of cormorant species, with a cosmopolitan distribution. Great cormorants are found throughout Europe, Asia, Africa, Australia, and in northeastern coastal North America. Populations in the western Atlantic and Europe have increased, with some range expansion, in the last 50 years.

Great cormorants are found in shallow, aquatic habitats, such as the coasts of oceans and large lakes and rivers. In North America, great cormorants are strongly associated with marine coastlines, in contrast to their smaller cousins, double-crested cormorants. In Europe, great cormorants are also found in inland, freshwater areas and in coastal estuaries. Nesting habits may vary among subspecies. North American great cormorants (P. c. carbo) nest mainly along coasts. Eurasian subspecies (P. c. sinensis) nest in inland areas, but the two subspecies sometimes occur in nesting colonies together in areas of recent overlap (British Isles).

29-1-2024 XERACO CAMPO, VALENCIA - WHITE WAGTAIL (Motacilla alba)

The White wagtail (Motacilla alba) is a small insectivorous bird of the open country, often near habitation and water. It prefers bare areas for feeding, where it can see and pursue its prey. In urban areas, it has adapted to foraging on paved areas such as car parks. It is the national bird of Latvia and has been featured on the stamps of several countries.

The White wagtail is a slender bird with the characteristic long, constantly wagging tail of its genus. There are a number of other subspecies, some of which may have arisen because of partial geographical isolation, such as the resident British and Irish form, the pied wagtail M. a. yarrellii, which now also breeds in adjacent areas of the neighbouring European mainland. The Pied wagtail exchanges the grey colour of the nominate form with black (or very dark grey in females), but is otherwise identical in its behaviour. Other subspecies, the validity of some of which is questionable, differ in the colour of the wings, back, and head, or other features. Some races show sexual dimorphism during the breeding season. As many as six subspecies may be present in the wintering ground in India or Southeast Asia and here they can be difficult to distinguish.

White wagtails breed throughout Eurasia, only being absent in the Arctic. They also breed in the mountains of Morocco and western Alaska. These birds are residents in the milder parts of their range such as western Europe and the Mediterranean, but migratory in much of the rest of their range. Northern European breeders winter around the Mediterranean and in tropical and subtropical Africa, and Asiatic birds move to the Middle East, India, and Southeast Asia. Birds from the North American population also winter in tropical Asia. White wagtails occupy a wide range of habitats but are absent from deserts. They inhabit grasslands, seashores, rocky shorelines, sand beaches, tidepools, rivers, lakeshores, farmland, gardens, and parks. They are also often found in towns and villages.

27-3-2015 GALLE, SRI LANKA - PARROT'S BEAK (Heliconia psittacorum)


Heliconia psittacorum (parrot's beak, parakeet flower, parrot's flower, parrot's plantain, false bird-of-paradise) is a perennial herb native to the Caribbean and South America. It is considered native to French Guiana, Guyana, Suriname, Venezuela, Colombia, Bolivia, Brazil, Paraguay, Panama and Trinidad and Tobago. It is reportedly naturalized in Gambia, Thailand, Puerto Rico, Hispaniola, Jamaica and the Lesser Antilles. It is often cultivated as a tropical ornamental plant in regions outside its native range.

The flower has both male parts (anthers) and female parts (stigma and pistil), also referred to as a monoecious angiosperm.

23-3-2015 PENANG HILLS, MALAYSIA - LONG TAILED MACAQUE MONKEY (Macaca fascicularis ssp. fascicularis)


The crab-eating macaque (Macaca fascicularis), also known as the long-tailed macaque and referred to as the cynomolgus monkey in laboratories, is a cercopithecine primate native to Southeast Asia. A species of macaque, the crab-eating macaque has a long history alongside humans. The species has been alternately seen as an agricultural pest, a sacred animal, and, more recently, the subject of medical experiments.

The crab-eating macaque lives in matrilineal social groups of up to eight individuals dominated by females. Male members leave the group when they reach puberty. It is an opportunistic omnivore and has been documented using tools to obtain food in Thailand and Myanmar. The crab-eating macaque is a known invasive species and a threat to biodiversity in several locations, including Hong Kong and western New Guinea. The significant overlap in macaque and human living space has resulted in greater habitat loss, synanthropic living, and inter- and intraspecies conflicts over resources.


26-1-2024 RIO SERPIS, GANDIA - EURASIAN BLACKBIRD (MALE) (Turdus merula)


The common blackbird (Turdus merula) is a species of true thrush. It is also called the Eurasian blackbird (especially in North America, to distinguish it from the unrelated New World blackbirds), or simply the blackbird where this does not lead to confusion with a similar-looking local species. It breeds in Europe, western Asia, and North Africa, and has been introduced to Australia and New Zealand. It has a number of subspecies across its large range; a few former Asian subspecies are now widely treated as separate species. Depending on latitude, the common blackbird may be resident, partially migratory, or fully migratory.

The adult male of the common blackbird (Turdus merula merula, the nominate subspecies), which is found throughout most of Europe, is all black except for a yellow eye-ring and bill and has a rich, melodious song; the adult female and juvenile have mainly dark brown plumage. This species breeds in woods and gardens, building a neat, cup-shaped nest, bound together with mud. It is omnivorous, eating a wide range of insects, earthworms, berries, and fruits.

Both sexes are territorial on the breeding grounds, with distinctive threat displays, but are more gregarious during migration and in wintering areas. Pairs stay in their territory throughout the year where the climate is sufficiently temperate. This common and conspicuous species has given rise to a number of literary and cultural references, frequently related to its song.

25-1-2024 MONTE CORONA, VALENCIA - VESPERID BEETLE (Vesperus xatarti)


Vesperus xatarti , known as castañeta , is a species of beetle insect in the family Vesperidae . These longicorns are distributed throughout peninsular Spain and the Balearic Islands and in the south of France . 

The chestnut measures between 18 and 30 mm , with adults being active all year round except in the middle of summer; causes significant damage to the olive tree . The females have an ovipositor and lay in groups on wood.

To combat it, the following methods can be used:

Monitoring the appearance of adults with traps.

Cultural methods: debarking.

Chemical fight: against neonatal larvae, with organophosphates (chlorpyrifos).

Biological fight: nematodes .

25-1-2024 MARXUQUERA, VALENCIA - EUROPEAN GOLDFINCH (Carduelis carduelis)


The Goldfinch is a colourful finch with a bright red face and yellow wing patch. It's a very sociable bird, often breeding in loose groups. It has a delightful twittering song and call. Their fine beaks allow them to extract otherwise inaccessible seeds from thistles and teasels. Increasingly, they are visiting bird tables and feeders. In winter, many UK Goldfinches migrate as far south as Spain.

The European goldfinch is illegally trafficked and can be found in countries worldwide, including the United States.

They attach their nests to tree twigs using spider silk.

Males and females look similar, but males have slightly larger red face masks that extend to their eyes.

They are frequent visitors to backyard feeders, especially those containing niger seeds.

They forage by hovering over plants and will occasionally feed upside down.

25-1-2024 MONTE CORONA, VALENCIA - SARDINIAN WARBLER (MALE) (Sylvia melanocephala)


The Sardinian warbler (Sylvia melanocephala ) is a common and widespread typical warbler from the Mediterranean region. Like most Curruca species, it has distinct male and female plumages. The adult male has a grey back, whitish underparts, black head, white throat and red eyes. Plumages are somewhat variable even in the same locality, with the intensity of a reddish hue on upper- and/or underside that varies from absent to (in some subspecies) pronounced. The female is mainly brown above and buff below, with a grey head. The Sardinian warbler's song is fast and rattling, and is very characteristic of the Mediterranean areas where this bird breeds.

It breeds in the southernmost areas of Europe and just into Asia in Turkey and the eastern end of the Mediterranean. This small passerine bird, unlike most "warblers", is not particularly migratory, but some birds winter in north Africa, and it occurs as a vagrant well away from the breeding range, as far as Great Britain.

24-1-2024 EL PERELLO, ALBUFERA - GREY HERON (Ardea cinerea)


The grey heron (Ardea cinerea) is a beautiful statuesque bird, native to vast swathes of the Eastern Hemisphere. It’s found in a broad range of wetland habitats from Britain to Norway, to Japan, and South Africa and almost every country in between - bar the hottest deserts, and the coldest mountain ranges.

Here in Britain, the grey heron is one of the tallest birds you’ll encounter, standing at over a metre in height. Its size, combined with its smart grey black and white whiskery plumage, makes this fishing specialist instantly recognisable. Despite its grand looks and a 6ft whopper of a wingspan, the average heron weighs little more than a pheasant, with bigger males only reaching a maximum of 2 kilograms.

The grey heron is quite vocal, with a variety of calls depending on behaviour. The most commonly heard is its grating ‘fraarnk’ flight call, and if alarmed it emits a ‘go-go-go’. An ‘oooo’ is used in courtship display (which is somewhat fitting), and they also ‘clap’ at each other with their bills in greeting and in mating displays.

Herons nest in big trees, in groups called heronries. These are often habitual sites that are revisited year after year and may involve dozens of nests, spanning multiple trees. The largest heronry in Britain is currently at Northward Hill in Kent, where numbers of nests are between 150 and 200! Herons start to nest quite early and it’s not unusual to see herons sitting on eggs in early February, but nesting activity peaks in late March.

24-1-2024 EL PERELLO, ALBUFERA - EURASIAN GREAT CORMORANT (Phalacrocorax carbo)

This is a very common and widespread bird species. It feeds on the sea, in estuaries, and on freshwater lakes and rivers. Northern birds migrate south and winter along any coast that is well-supplied with fish.

In Serbia, the cormorant lives in Vojvodina. However, after 1945 many artificial lakes were formed in Serbia; some of them became potential habitats for cormorants. Currently, on the Lake Ćelije, formed in 1980, there is a resident colony of cormorants, who nest there and are present throughout the year, except January–February 1985 and February 2012 when the lake surface was completely frozen.

The type subspecies, P. c. carbo, is found mainly in Atlantic waters and nearby inland areas: on western European coasts and east across the Palearctic to Siberia and to North Africa, the Faroe Islands, Iceland and Greenland; and on the eastern seaboard of North America. The subspecies P. c. novaehollandiae is found in Australian waters.

24-1-2024 MUNTANYETA DEL SANS, ALBUFERA - EUROPEAN MOORHEN (Gallinula chloropus)


The common moorhen (Gallinula chloropus), also known as the waterhen or swamp chicken, is a bird species in the rail family (Rallidae). It is distributed across many parts of the Old World.

The common moorhen lives around well-vegetated marshes, ponds, canals and other wetlands. The species is not found in the polar regions or many tropical rainforests. Elsewhere it is likely the most common rail species, except for the Eurasian coot in some regions.

The closely related common gallinule of the New World has been recognized as a separate species by most authorities, starting with the American Ornithologists' Union and the International Ornithological Committee in 2011.

24-1-2024 MUNTANYETA DEL SANS, ALBUFERA - MEADOW PIPIT (Anthus pratensis)

The meadow pipit (Anthus pratensis) is a small passerine bird, which breeds in much of the Palearctic, from southeastern Greenland and Iceland east to just east of the Ural Mountains in Russia, and south to central France and Romania; an isolated population also occurs in the Caucasus Mountains. It is migratory over most of its range, wintering in southern Europe, North Africa, and south-western Asia, but is resident year-round in western Europe, though even here many birds move to the coast or lowlands in winter.

This is a widespread and often abundant small pipit, 14.5–15 cm (5+1⁄2–6 in) long and 15–22 g (0.53–0.78 oz) weight. It is an undistinguished-looking species on the ground, mainly brown above and buff below, with darker streaking on most of its plumage; the tail is brown, with narrow white side edges. It has a thin bill and pale pinkish-yellow legs; the hind claw is notably long, longer than the rest of the hind toes. The call is a weak tsi-tsi. The simple repetitive song is given in a short song flight. Birds breeding in Ireland and western Scotland are slightly darker coloured than those in other areas, and are often distinguished as the subspecies A. p. whistleri, though it intergrades clinally with nominate A. p. pratensis found in the rest of the species' range. 

It is similar to the red-throated pipit A. cervinus, which is more heavily streaked and (in summer only) has an orange-red throat, and to the tree pipit A. trivialis, which is slightly larger, less heavily streaked, and has stronger facial markings and a shorter hind claw. The song of the meadow pipit accelerates towards the end while that of the tree pipit slows down.


It is primarily a species of open habitats, either uncultivated or low-intensity agriculture, such as pasture, bogs, and moorland, but also occurs in low numbers in arable croplands. In winter, it also uses saltmarshes and sometimes open woodlands. It is a fairly terrestrial pipit, always feeding on the ground, but uses elevated perches such as shrubs, fence lines, or electricity wires as vantage points to watch for predators.
The estimated total population is 12 million pairs. It is an abundant species in the north of its range, and generally the commonest breeding bird in most of upland Britain, but less common further south. Breeding densities range from 80 pairs/km2 (210 pairs/sq mi) in northern Scandinavia, to 5–20 pairs/km2 (13–52 pairs/sq mi) in grassland in the south of the breeding range, and just 1/km2 (2.6/sq mi) in arable farmland. A few isolated breeding pairs are recorded from south of the main range, in the mountains of Spain, Italy, and the northern Balkans. A general decline in the population has occurred over the past 17 years, most notable in French farmland, with a 68% drop.
 

24-1-2024 SUECA CAMPO DE ARROZ, ALBUFERA - EURASIAN KESTREL (Falco tinnunculus)


Common kestrels measure 32–39 cm (12+1⁄2–15+1⁄2 in) from head to tail, with a wingspan of 65–82 cm (25+1⁄2–32+1⁄2 in). Females are noticeably larger, with the adult male weighing 136–252 g (4+3⁄4–8+7⁄8 oz), around 155 g (5+1⁄2 oz) on average; the adult female weighs 154–314 g (5+3⁄8–11+1⁄8 oz), around 184 g (6+1⁄2 oz) on average. They are thus small compared with other birds of prey, but larger than most songbirds. Like the other Falco species, they have long wings as well as a distinctive long tail.

Their plumage is mainly light chestnut brown with blackish spots on the upperside and buff with narrow blackish streaks on the underside; the remiges are also blackish. Unlike most raptors, they display sexual colour dimorphism with the male having fewer black spots and streaks, as well as a blue-grey cap and tail. The tail is brown with black bars in females, and has a black tip with a narrow white rim in both sexes. All common kestrels have a prominent black malar stripe like their closest relatives.

The cere, feet, and a narrow ring around the eye are bright yellow; the toenails, bill and iris are dark. Juveniles look like adult females, but the underside streaks are wider; the yellow of their bare parts is paler. Hatchlings are covered in white down feathers, changing to a buff-grey second down coat before they grow their first true plumage. 

24-1-2024 ULLAL DE BALDOVI, ALBUFERA - COMMON CHIFFCHAFF (Phylloscopus collybita)

The common chiffchaff (Phylloscopus collybita), or simply the chiffchaff, is a common and widespread leaf warbler which breeds in open woodlands throughout northern and temperate Europe and the Palearctic.

It is a migratory passerine which winters in southern and western Europe, southern Asia and north Africa. Greenish-brown above and off-white below, it is named onomatopoeically for its simple chiff-chaff song. It has a number of subspecies, some of which are now treated as full species. The female builds a domed nest on or near the ground, and assumes most of the responsibility for brooding and feeding the chicks, whilst the male has little involvement in nesting, but defends his territory against rivals, and attacks potential predators.

A small insectivorous bird, it is subject to predation by mammals, such as cats and mustelids, and birds, particularly hawks of the genus Accipiter. Its large range and population mean that its status is secure, although one subspecies is probably extinct.


The British naturalist Gilbert White was one of the first people to separate the similar-looking common chiffchaff, willow warbler and wood warbler by their songs, as detailed in 1789 in The Natural History and Antiquities of Selborne, but the common chiffchaff was first formally described as Sylvia collybita by French ornithologist Louis Pierre Vieillot in 1817 in his Nouveau Dictionnaire d'Histoire Naturelle. The type locality is the French region of Normandy.

Described by German zoologist Friedrich Boie in 1826, the genus Phylloscopus contains about 80 species of small insectivorous Old World woodland warblers which are either greenish or brown above and yellowish, white or buff below. The genus was formerly part of the Old World warbler family Sylvidae, but has now been split off as a separate family Phylloscopidae. The chiffchaff's closest relatives, other than former subspecies, are a group of leaf warblers which similarly lack crown stripes, a yellow rump or obvious wing bars; they include the willow, Bonelli's, wood and plain leaf warblers.

An old synonym, used for the chiffchaff was Phylloscopus rufus (Bechstein).

The common chiffchaff has three still commonly accepted subspecies, together with some from the Iberian Peninsula, the Canary Islands, and the Caucasus which are now more often treated as full species.

22-1-2024 PARCENT, ALICANTE - WHITE WAGTAIL (Motacilla alba)

The white wagtail (Motacilla alba) is a small passerine bird in the family Motacillidae, which also includes pipits and longclaws. The species breeds in much of Europe and the Asian Palearctic and parts of North Africa. It has a toehold in Alaska as a scarce breeder. It is resident in the mildest parts of its range, but otherwise migrates to Africa. In Ireland and Great Britain, the darker subspecies, the pied wagtail or water wagtail (M. a. yarrellii) predominates; this is also called in Ireland willie wagtail, not to be confused with the Australian species Rhipidura leucophrys which bears the same common name. In total, there are between 9 and 11 subspecies of M. alba.

The white wagtail is an insectivorous bird of open country, often near habitation and water. It prefers bare areas for feeding, where it can see and pursue its prey. In urban areas it has adapted to foraging on paved areas such as car parks. It nests in crevices in stone walls and similar natural and human-made structures.

It is the national bird of Latvia and has featured on the stamps of several countries. Though it is 'of least concern', there are several threats against it, like being kept as pets and being used as food.


 

22-1-2024 PARCENT, ALICANTE - CLEOPATRA BUTTERFLY (Gonepteryx cleopatra)

Cleopatra butterfly, is a medium-sized butterfly of the family Pieridae.

Gonepteryx cleopatra is a medium-sized butterfly with a wingspan of about 50–70 mm (2.0–2.8 in). It is a sexually dimorphic species; the female has pale yellow or greenish wings, whereas the male is darker yellow with an orange patch on the forewing. Both sexes have a forewing apical hook and brown dots in the center of each wing, and the underside of wings is light greenish yellow. The greenish color, the shape and the pronounced venation on the hindwings give to these butterflies a good camouflage, making them resemble just leaves.


The Cleopatra butterfly inhabits open woodland and scrub. The flight period is from May to August in most parts of its range, except Spain, where it is double brooded and may fly almost all year. The adult hibernates in evergreen trees and shrubs. The caterpillars feed on the buckthorns Rhamnus alaternus. When the green caterpillars are prepared to pass to the pupal stage, they tie themselves through a silk belt to the host plant, on the underside of a leaf. The green chrysalis became gradually yellow and red, revealing the colors on the wings of the adult close to flutter.

This species is native to the Mediterranean region (Southern Europe, North Africa and West Asia).

21-1-2024 MONTE CORONA, VALENCIA - MESSOR HARVESTER ANT (Genus Messor)

Messor is a myrmicine genus of ants with more than 100 species, all of which are harvester ants; the generic name comes from the Roman god of crops and harvest, Messor. The subterranean colonies tend to be found in open fields and near roadsides, openings are directly to the surface.

Colonies can achieve huge sizes and are notable for their intricately designed granaries in which seeds are stored in dry conditions, preventing germination. The structure of Messor spp. nests is complex and the genus on the whole is one of very accomplished architects.

Messor spp. are polymorphic and have a distinct caste of macrocephalic dinoergates whose role is carrying and cutting the large seeds which comprise much of the colonies' subsistence. Although they primarily feed on seeds, they occasionally eat insects and snails. Some snail shells possibly are taken into the nest because of their grain-like shape.

Equipped with a tough, shining cuticle, Messor spp. are slow-moving and form long, seed-carrying runs. Colonies tend to be monogynous - founded by a single queen alone.

Looking specifically at the M. arenarius species for example, like some other types of harvester ants, they emit trail pheromones as well as operating on an individual level when looking for food sources.



2-1-2024 CALYPSO BAR, GAMBIA - WESTERN REEF HERON (Egretta gularis)

Gangly heron with significant variation in plumage. Distinct dark morph is slate-gray with a white throat, while the palest morph is white with a yellow bill and lores. Pale gray intermediate morphs can also be found. Little Egret can look similar, but it has a darker bill than the white morph of the Western Reef-Heron. Primarily a coastal inhabitant, foraging on shorelines and in estuaries, but can also be found at some inland water bodies.

The western reef heron (Egretta gularis ), also called the western reef egret, is a medium-sized heron found in southern Europe, Africa and parts of Asia. It has a mainly coastal distribution and occurs in several plumage forms: a slaty-grey plumage in which it can only be confused with the rather uncommon dark morph of the Little egret (Egretta garzetta ); a white form which can look very similar to the little egret although the bill tends to be paler and larger and the black form with white throat E. g. gularis of West Africa. There are also differences in size, structure and foraging behaviour. There have been suggestions that the species hybridizes with the Little Egret, and based on this, some authors treat schistacea and gularis as subspecies of Egretta garzetta. Works that consider the Western Reef Heron as a valid species include the nominate gularis and schistacea as subspecies.

21-1-2024 ADOR CAMPO, VALENCIA - MEADOW PIPIT (Anthus pratensis)

The meadow pipit (Anthus pratensis) is a small passerine bird, which breeds in much of the Palearctic, from southeastern Greenland and Iceland east to just east of the Ural Mountains in Russia, and south to central France and Romania; an isolated population also occurs in the Caucasus Mountains. It is migratory over most of its range, wintering in southern Europe, North Africa, and south-western Asia, but is resident year-round in western Europe, though even here many birds move to the coast or lowlands in winter.

This is a widespread and often abundant small pipit, 14.5–15 cm (5+1⁄2–6 in) long and 15–22 g (0.53–0.78 oz) weight. It is an undistinguished-looking species on the ground, mainly brown above and buff below, with darker streaking on most of its plumage; the tail is brown, with narrow white side edges. It has a thin bill and pale pinkish-yellow legs; the hind claw is notably long, longer than the rest of the hind toes. The call is a weak tsi-tsi. The simple repetitive song is given in a short song flight. Birds breeding in Ireland and western Scotland are slightly darker coloured than those in other areas, and are often distinguished as the subspecies A. p. whistleri, though it intergrades clinally with nominate A. p. pratensis found in the rest of the species' range.

It is similar to the red-throated pipit A. cervinus, which is more heavily streaked and (in summer only) has an orange-red throat, and to the tree pipit A. trivialis, which is slightly larger, less heavily streaked, and has stronger facial markings and a shorter hind claw. The song of the meadow pipit accelerates towards the end while that of the tree pipit slows down.


21-1-2024 ARROZ CAMPO CULLERA, VALENCIA - EUROPEAN STONECHAT (MALE) (Saxicola rubicola)


The European stonechat (Saxicola rubicola) is a small passerine bird that was formerly classed as a subspecies of the common stonechat. Long considered a member of the thrush family, Turdidae, genetic evidence has placed it and its relatives in the Old World flycatcher family, Muscicapidae.

European stonechats breed in heathland, coastal dunes and rough grassland with scattered small shrubs and bramble, open gorse, tussocks or heather. They are short-distance migrants or non-migratory, with part of the population (particularly from northeastern parts of the range, where winters are colder) moving south to winter further south in Europe and more widely in north Africa.

21-1-2024 CULLERA, VALENCIA - COMMON CHIFFCHAFF (Phylloscopus collybita)


The common chiffchaff (Phylloscopus collybita), or simply the chiffchaff, is a common and widespread leaf warbler which breeds in open woodlands throughout northern and temperate Europe and the Palearctic.

It is a migratory passerine which winters in southern and western Europe, southern Asia and north Africa. Greenish-brown above and off-white below, it is named onomatopoeically for its simple chiff-chaff song. It has a number of subspecies, some of which are now treated as full species. The female builds a domed nest on or near the ground, and assumes most of the responsibility for brooding and feeding the chicks, whilst the male has little involvement in nesting, but defends his territory against rivals, and attacks potential predators.

A small insectivorous bird, it is subject to predation by mammals, such as cats and mustelids, and birds, particularly hawks of the genus Accipiter. Its large range and population mean that its status is secure, although one subspecies is probably extinct. 

21-1-2024 CULLERA, VALENCIA - WHITE WAGTAIL (Motacilla alba)


The white wagtail (Motacilla alba) is a small passerine bird in the family Motacillidae, which also includes pipits and longclaws. The species breeds in much of Europe and the Asian Palearctic and parts of North Africa. It has a toehold in Alaska as a scarce breeder. It is resident in the mildest parts of its range, but otherwise migrates to Africa. In Ireland and Great Britain, the darker subspecies, the pied wagtail or water wagtail (M. a. yarrellii) predominates; this is also called in Ireland willie wagtail, not to be confused with the Australian species Rhipidura leucophrys which bears the same common name. In total, there are between 9 and 11 subspecies of M. alba.

The white wagtail is an insectivorous bird of open country, often near habitation and water. It prefers bare areas for feeding, where it can see and pursue its prey. In urban areas it has adapted to foraging on paved areas such as car parks. It nests in crevices in stone walls and similar natural and human-made structures.

It is the national bird of Latvia and has featured on the stamps of several countries. Though it is 'of least concern', there are several threats against it, like being kept as pets and being used as food.

21-1-2024 CULLERA, VALENCIA - LITTLE EGRET (Egretta garzetta)

Little egrets are sociable birds and are often seen in small flocks. Nevertheless, individual birds do not tolerate others coming too close to their chosen feeding site, though this depends on the abundance of prey.

They use a variety of methods to procure their food; they stalk their prey in shallow water, often running with raised wings or shuffling their feet to disturb small fish, or may stand still and wait to ambush prey. They make use of opportunities provided by cormorants disturbing fish or humans attracting fish by throwing bread into water. On land they walk or run while chasing their prey, feed on creatures disturbed by grazing livestock and ticks on the livestock, and even scavenge. Their diet is mainly fish, but amphibians, small reptiles, mammals and birds are also eaten, as well as crustaceans, molluscs, insects, spiders and worms.


 

21-1-2024 MONTE CORONA, VALENCIA - SARDINIAN WARBLER (MALE) (Sylvia melanocephala)


The Sardinian warbler (Curruca melanocephala) is a common and widespread typical warbler from the Mediterranean region. Like most Curruca species, it has distinct male and female plumages. The adult male has a grey back, whitish underparts, black head, white throat and red eyes. Plumages are somewhat variable even in the same locality, with the intensity of a reddish hue on upper- and/or underside that varies from absent to (in some subspecies) pronounced. The female is mainly brown above and buff below, with a grey head. The Sardinian warbler's song is fast and rattling, and is very characteristic of the Mediterranean areas where this bird breeds. 

21-1-2024 CULLERA, VALENCIA - EURASIAN GREAT CORMORANT (Phalacrocorax carbo)

The great cormorant (Phalacrocorax carbo), known as the black shag or kawau in New Zealand, formerly also known as the great black cormorant across the Northern Hemisphere, the black cormorant in Australia, and the large cormorant in India, is a widespread member of the cormorant family of seabirds. The genus name is Latinised Ancient Greek, from φαλακρός (phalakros, "bald") and κόραξ (korax, "raven"), and carbo is Latin for "charcoal".

It breeds in much of the Old World, Australia, and the Atlantic coast of North America.

The great cormorant is a large black bird, but there is a wide variation in size in the species' wide range. Weight is reported to vary from 1.5 kg (3 lb 5 oz) to 5.3 kg (11 lb 11 oz). Males are typically larger and heavier than females, with the nominate race (P. c. carbo) averaging about 10% larger in linear measurements than the smallest race in Europe (P. c. sinensis). The lightest average weights cited are in Germany (P. c. sinensis), where 36 males averaged 2.28 kg (5 lb 1⁄2 oz) and 17 females averaged 1.94 kg (4 lb 4+1⁄2 oz). The highest come from Prince Edward Island in Canada (P. c. carbo), where 11 males averaged 3.68 kg (8 lb 2 oz) and 11 females averaged 2.94 kg (6 lb 7+1⁄2 oz). Length can vary from 70 to 102 cm (27+1⁄2 to 40 in) and wingspan from 121 to 160 cm (47+1⁄2 to 63 in). They are tied as the second largest extant species of cormorant after the flightless cormorant, with the Japanese cormorant averaging at a similar size. In bulk if not in linear dimensions, the blue-eyed shag species complex of the Southern Oceans are scarcely smaller at average. It has a longish tail and yellow throat-patch. Adults have white patches on the thighs and on the throat in the breeding season. In European waters it can be distinguished from the common shag by its larger size, heavier build, thicker bill, lack of a crest and plumage without any green tinge. In eastern North America, it is similarly larger and bulkier than double-crested cormorant, and the latter species has more yellow on the throat and bill and lack the white thigh patches frequently seen on great cormorants. Great cormorants are mostly silent, but they make various guttural noises at their breeding colonies.

This is a very common and widespread bird species. It feeds on the sea, in estuaries, and on freshwater lakes and rivers. Northern birds migrate south and winter along any coast that is well-supplied with fish.

In Serbia, the cormorant lives in Vojvodina. However, after 1945 many artificial lakes were formed in Serbia; some of them became potential habitats for cormorants. Currently, on the Lake Ćelije, formed in 1980, there is a resident colony of cormorants, who nest there and are present throughout the year, except January–February 1985 and February 2012 when the lake surface was completely frozen.

The type subspecies, P. c. carbo, is found mainly in Atlantic waters and nearby inland areas: on western European coasts and east across the Palearctic to Siberia and to North Africa, the Faroe Islands, Iceland and Greenland; and on the eastern seaboard of North America. The subspecies P. c. novaehollandiae is found in Australian waters.

The great cormorant often nests in colonies near wetlands, rivers, and sheltered inshore waters. Pairs will use the same nest site to breed year after year. It builds its nest, which is made from sticks, in trees, on the ledges of cliffs, and on the ground on rocky islands that are free of predators.

This cormorant lays a clutch of three to five eggs that measure 63 by 41 millimetres (2+1⁄2 by 1+5⁄8 in) on average. The eggs are a pale blue or green, and sometimes have a white chalky layer covering them. These eggs are incubated for a period of about 28 to 31 days. 


The great cormorant feeds on fish caught through diving. This bird feeds primarily on wrasses, but it also takes sand smelt, flathead and common soles. The average weight of fish taken by great cormorants increased with decreasing air and water temperature. Cormorants consume all fish of appropriate size that they are able to catch in summer and noticeably select for larger, mostly torpedo-shaped fish in winter. Thus, the winter elevation of foraging efficiency described for cormorants by various researchers is due to capturing larger fish not due to capturing more fish. In some freshwater systems, the losses of fish due to overwintering great cormorants were estimated to be up to 80 kg per ha each year (e.g. Vltava River, Czech Republic).


This cormorant forages by diving and capturing its prey in its beak. The duration of its dives is around 28 seconds, with the bird diving to depths of about 5.8 metres (19 ft 0 in). About 60% of dives are to the benthic zone and about 10% are to the pelagic zone, with the rest of the dives being to zones in between the two. Studies suggest that their hearing has evolved for underwater usage, possibly aiding their detection of fish. These adaptations also have a cost on their hearing ability in air which is of lowered sensitivity.
