28-9-2017 CAMI LES FONTS OLIVA, VALENCIA - GREYLAG GOOSE (Anser anser)

The Greylag goose (Anser anser) is a large goose in the waterfowl family Anatidae. Its distribution is widespread, with birds from the north of its range in Europe and Asia migrating southwards to spend the winter in warmer places. It is the ancestor of most breeds of domestic goose, having been domesticated at least as early as 1360 BC.

The Greylag is the largest and bulkiest of the grey geese of the genus Anser, but is more lightly built and agile than its domestic relative. It has a rotund, bulky body, a thick and long neck, and a large head and bill. It has pink legs and feet, and an orange or pink bill with a white or brown nail (hard horny material at the tip of the upper mandible). The plumage of the Greylag goose is greyish brown, with a darker head and paler breast and belly with a variable amount of black spotting. It has a pale grey forewing and rump which are noticeable when the bird is in flight or stretches its wings on the ground. It has a white line bordering its upper flanks, and its wing coverts are light-colored, contrasting with its darker flight feathers. Its plumage is patterned by the pale fringes of the feathers. Juveniles differ mostly in their lack of black speckling on the breast and belly and by their greyish legs. Adults have a distinctive 'concertina' pattern of folds in the feathers on their necks.

28-9-2017 MARJAL DE OLIVA, VALENCIA - WHITE WAGTAIL (Motacilla alba)

The White Wagtail (Motacilla alba) is a small, elegant passerine bird, a member of the family Motacillidae, which includes pipits and longclaws. This slender bird measures between 16.5 to 19 cm in length, with East Asian subspecies reaching up to 21 cm. It is characterized by its long, constantly wagging tail, a behavior that has become synonymous with the genus. Weighing an average of 25 g, the White Wagtail can live up to 12 years in the wild.

Adult White Wagtails exhibit a distinctive plumage with a combination of grey, black, and white. The bird's upper parts are generally grey, with a white face, belly, and breast. Males during the breeding season may show a darker back, and the species is known for its sharp, brisk call and more melodious song during courtship.

The White Wagtail is commonly found in open country, often in close proximity to human habitation and water sources. It shows a preference for bare areas which facilitate the sighting and pursuit of prey. This bird has adapted well to urban environments, utilizing paved areas such as parking lots for foraging.

This species has a vast breeding range across Europe, the Asian Palearctic, parts of North Africa, and has a presence in Alaska. It is a migratory bird, with populations moving to Africa and parts of Asia during the winter. In Great Britain and Ireland, the darker subspecies known as the Pied Wagtail is more prevalent.

The White Wagtail is known for its perpetual tail wagging, a behavior that remains somewhat enigmatic but is thought to be a signal of vigilance to predators. It is a monogamous bird that defends its breeding territory with determination.

27-9-2017 MARJAL DE MOROS, SAGUNTO - RUDDY DARTER DRAGONFLY

The ruddy darter is to be found in temperate regions throughout Europe as far east as Siberia and as far south as the northern Sahara. Its conservation status is regarded as secure, and indeed numbers seem to be increasing in some locations such as central England.

It is present in the following countries: Albania; Algeria; Armenia; Austria; Azerbaijan; Belarus; Belgium; Bosnia and Herzegovina; Bulgaria; Croatia; Cyprus; Czech Republic; Denmark; Estonia; Finland; France; Germany; Greece; Hungary; Ireland; Italy; Kazakhstan; Kyrgyzstan; Latvia; Liechtenstein; Lithuania; Luxembourg; Macedonia, the former Yugoslav Republic of; Moldova; Monaco; Montenegro; Morocco; Netherlands; Norway; Poland; Portugal; Romania; Russian Federation; Serbia; Slovakia; Slovenia; Spain; Sweden; Switzerland; Tajikistan; Tunisia; Turkmenistan; Ukraine; United Kingdom; Uzbekistan. 

This species tends to prefer quiet bodies of water that feature semiaquatic vegetation such as rushes and reeds.

The ruddy darter can reach a body length of 34–36 millimetres (1.3–1.4 in)[3] and attains a wingspan of up to 6 cm (2.4 in). These dragonflies are smaller than the common darter. They have black legs and the wings show a brown pterostigma and an orange color at the base of the wings. Two evident black marks are located on segments S8 and S9 of the abdomen.

The head, thorax and abdomen of the mature male are vivid red, while the female is slightly smaller, and is a golden-yellow colour with black markings. The blood-red color of the males develop with maturity, together with a red frons and a red-brown thorax.  The abdomen widens for the final third of its length and shows a marked pinched section where it joins the thorax.

The all-black legs of the ruddy darter distinguish it from the otherwise very similar common darter (Sympetrum striolatum) and vagrant darter (Sympetrum vulgatum), both of which show yellow stripes on their legs. The spotted darter (Sympetrum depressiusculum) with all-black legs has noticeably more clubbed abdomen and brighter pterostigmata.

The ruddy darter can be found between the months of June and November.  Mating takes place on the wing, with the coupled pair performing a dipping flight over the water. The female jettisons her fertilised eggs at the water surface by alternating movements of the abdomen. The male may hover nearby during this period and protect the female by driving off any approaching males.

The larvae spend the year beneath the water surface before emerging and pupating into adults.

27-9-2017 MARJAL DE MOROS, SAGUNTO - LITTLE EGRET (Egretta garzetta)

The Little Egret, Egretta garzetta, is a dainty heron adorned in pure white plumage. It is characterized by a slender black beak, long black legs, and, notably in the western race, yellow feet. This elegant bird is a sight to behold with its graceful neck and poised stance.

Adult Little Egrets measure between 55–65 cm in length with a wingspan of 88–106 cm, and weigh 350–550 g. Their plumage is predominantly white, though some may exhibit bluish-grey coloration. Breeding adults boast ornate nape plumes reaching about 150 mm, along with distinctive feathers on the breast and elongated scapulars. The bill and lores are black, with greenish-grey skin at the base of the lower mandible and around the eye, which houses a yellow iris. Legs are black with contrasting yellow feet, though juveniles may have greenish-black legs and duller feet. The subspecies E. g. nigripes is distinguished by yellow skin between the bill and eye, and blackish feet.

The Little Egret frequents a variety of wetland habitats, from the shores of lakes and rivers to marshes and coastal regions. It is often found in open environments, such as mangroves, swamps, mudflats, and sandy beaches, as well as human-altered landscapes like rice fields.

The species has a broad breeding distribution across warm temperate to tropical regions of Asia, Africa, Australia, and Europe. Northern populations are migratory, wintering in Africa and southern Asia, while others remain as permanent residents in warmer areas.

Little Egrets are social yet territorial when feeding. They exhibit a range of foraging behaviors, from active chasing to patient ambush. Their movements are often in response to the presence of other animals, which may stir up prey.

The Little Egret's vocalizations include croaking and bubbling sounds at breeding colonies and a harsh alarm call when disturbed. These calls are similar to those of the Black-crowned Night Heron and the Cattle Egret.

Breeding colonies are often mixed with other water birds. Nests are platforms of sticks located in trees, shrubs, or reed beds. Clutches typically consist of three to five bluish-green eggs, incubated by both parents for about three weeks. The young fledge at approximately six weeks old.

The diet is diverse, including fish, amphibians, small reptiles, mammals, birds, crustaceans, molluscs, insects, spiders, and worms. The Little Egret employs various hunting techniques, both in water and on land, to capture its prey.

The Little Egret is classified as "Least Concern" by the IUCN. Conservation measures in the 20th century have allowed populations to recover in Europe, and the species has been expanding its range. It is now successfully colonizing new areas, including the New World.

27-9-2017 MARJAL DE MOROS, SAGUNTO - GREATER FLAMINGO (JUVENILE) (Phoenicopterus roseus)

The greater flamingo, Phoenicopterus roseus, stands as the most widespread and largest member of the flamingo family. This majestic bird is adorned with pinkish-white plumage, save for the red wing coverts and contrasting black primary and secondary flight feathers. The bill is a striking pink with a black tip, and the legs are a uniform pink, completing the iconic look of this species.

Adult greater flamingos can be identified by their height, ranging from 110 to 150 cm, and their weight between 2 and 4 kg. The largest males can reach up to 187 cm tall and weigh 4.5 kg. Observers should note the distinctive coloration, with the majority of the body being pinkish-white, red wing coverts, and black flight feathers. The pink bill with a black tip and entirely pink legs are also key identification features. The call of the greater flamingo is reminiscent of a goose-like honking.

Observers should note the distinctive coloration, with the majority of the body being pinkish-white, red wing coverts, and black flight feathers. The pink bill with a black tip and entirely pink legs are also key identification features. The call of the greater flamingo is reminiscent of a goose-like honking.

Greater flamingos favor mudflats and shallow coastal lagoons with saline water, where they can be seen stirring the mud with their feet in search of food.

This species is common in the Old World, with a range that includes Northern and Sub-Saharan Africa, the Indian Subcontinent, the Middle East, the Levant, and Southern Europe. Notably, they are found in coastal regions and along water bodies such as the Nile River, the Persian Gulf, the Gulf of Aden, the Red Sea, and the Mediterranean.

Greater flamingos are social birds, often found in large flocks. They feed with their heads down, filtering out sustenance from the water with their specially adapted bills. During the breeding season, these birds engage in a fascinating display of spreading uropygial secretions over their feathers to enhance their color, a behavior likened to applying "make-up."

The vocalization of the greater flamingo is a distinctive honking, similar to that of a goose, which can be heard over considerable distances.

The species lays a single chalky-white egg on a mud mound, a typical breeding behavior for flamingos.

While similar to the American flamingo, the greater flamingo can be distinguished by differences in head, neck, body, and bill coloration.

Greater flamingos feed on a diet that includes small shrimp, seeds, blue-green algae, microscopic organisms, and mollusks. They filter their food from the water with their downward-facing heads and movable upper jaws.

The IUCN Red List classifies the greater flamingo as Least Concern, indicating a stable population. However, they face threats from habitat encroachment and pollution in their water supplies.

In the voice of David Attenborough, one might say: "The greater flamingo, with its elegant stature and vibrant hues, is a testament to the wonders of the avian world. As it sifts through the shallows, one cannot help but be captivated by its grace and the delicate balance it maintains within its ecosystem."

27-9-2017 MARJAL DE MOROS, SAGUNTO - EARED GREBE (JUVENILE) (Podiceps nigricollis)

The Black-necked Grebe, also known as the Eared Grebe (Podiceps nigricollis), is a striking member of the grebe family. It is characterized by its distinctive breeding plumage, which includes a black to blackish-brown head, neck, and breast, and ochre-colored feathers that fan out behind the eyes over the ear coverts. The flanks are a rich tawny rufous to maroon-chestnut, while the abdomen remains white. In non-breeding plumage, the bird sports greyish-black upper parts and a white or whitish body. Juveniles have a browner hue in their darker areas.

To identify the Black-necked Grebe, look for the red eye with a narrow yellow ring, the blackish line extending from the gape to the eye, and the thin, upturned black bill. The subspecies californicus typically has a longer bill, while P. n. gurneyi is smaller with a greyer head and lacks non-breeding plumage.

This species favors vegetated freshwater lakes for breeding and migrates to saline lakes and coastal estuaries post-breeding.

The Black-necked Grebe has a wide distribution, breeding across parts of Africa, Eurasia, and the Americas. It winters in locations such as the southwestern Palearctic, eastern parts of Africa and Asia, southern Africa, and as far south as Guatemala in the Americas.

The Black-necked Grebe is a reluctant and inefficient flier, often avoiding flight except during migration. It can travel up to 6,000 kilometers during migration and becomes flightless for two months during the moulting period.

During the breeding season, the Black-necked Grebe emits a high-pitched "ooeek" call that ascends in pitch, used for both territorial and courtship purposes. Outside of breeding, it is generally silent.

Breeding occurs in various locations depending on the subspecies, with a floating cup nest built on open lakes. The species is socially monogamous and may lay one or sometimes two clutches of three to four eggs, with brood parasitism being common.

The Black-necked Grebe can be confused with other grebe species, but its distinctive breeding plumage and vocalizations help differentiate it.

The diet consists mainly of insects, crustaceans, molluscs, tadpoles, small frogs, and fish. It employs multiple foraging techniques, including diving, foliage gleaning, and capturing flying insects.

The IUCN classifies the Black-necked Grebe as Least Concern, with an estimated population of 3.9–4.2 million individuals. Despite potential threats like oil spills and disease outbreaks, these are not considered significant risks to the overall population.

27-9-2017 MARJAL DE MOROS, SAGUNTO - ZITTING CISTICOLA (Cisticola juncidis)

The Zitting Cisticola, or Streaked Fantail Warbler, is a diminutive bird, measuring a mere 10 to 12 centimeters in length. Its upper parts are adorned with a brown plumage, intricately streaked with black, while its underparts remain a modest whitish hue. The tail is a noteworthy feature, broad and tipped with white, and is frequently flicked—a behavior that has inspired one of the bird's colloquial names.

To identify the Zitting Cisticola, look for its rufous rump and the absence of gold on the collar. The tail, brownish with white tips, is another distinguishing characteristic. Males, during the breeding season, exhibit less crown streaking and more pronounced back markings than females, though differences between sexes are generally subtle.

The Zitting Cisticola favors grasslands as its primary habitat, often found in proximity to bodies of water.

This species boasts a broad range, encompassing southern Europe, Africa (excluding deserts and rainforests), and southern Asia, extending to northern Australia. It is largely sedentary, though certain East Asian populations undertake migrations to warmer climes in winter.

These birds are predominantly insectivorous and may be observed in small flocks. The breeding season is timed with the rains, and in many regions, the Zitting Cisticola is known to produce two broods annually. Males display polygynous tendencies, though monogamous pairings are not uncommon. The male initiates nest construction within the grasses and performs a specialized display to attract females, who then complete the nest.

The male's breeding season is marked by a distinctive flight display, punctuated by a series of "zitting" calls reminiscent of the sound of scissors snipping.

Nests are artfully constructed with living leaves woven into a soft matrix of plant down, cobwebs, and grass. The structure is cup-shaped with an overhead canopy for camouflage. Females lay 3 to 6 eggs and are solely responsible for incubation, which lasts approximately 10 days. Multiple broods may be raised in a single season.

The Zitting Cisticola can be differentiated from the Golden-headed Cisticola (Cisticola exilis) by the absence of a nuchal collar.

Their diet consists primarily of insects, which they forage for within their grassland habitats.

The Zitting Cisticola is classified as Least Concern by the IUCN, indicating a stable population without immediate threats to its survival.

27-9-2017 MARJAL DE MOROS, SAGUNTO - EURASIAN COOT (JUVENILE) (Fulica atra)

The Eurasian coot (Fulica atra), also known as the Common coot, or Australian coot, is a member of the rail and crake bird family, the Rallidae. It is found in Europe, Asia, Australia, New Zealand, and parts of North Africa. Similar-looking coot species are found throughout the world, with the largest variety of coot species living in South America.

The Eurasian coot is 36–38 cm (14–15 in) in length with a wing-span of 70–80 cm (28–31 in); males weigh around 890 g (31 oz) and females 750 g (26 oz). It is largely black except for the white bill and frontal shield (which gives rise to the phrase "as bald as a coot", in use as early as 1430). As a swimming species, the coot has partial webbing on its long strong toes. The sexes are similar in appearance.

The juvenile is paler than the adult, has a whitish breast, and lacks the facial shield; the adult black plumage develops when about 3–4 months old, but the white shield is only fully developed at about one year old.

Eurasian coots breed in Europe, Asia, Australia, and Africa. They have recently expanded their range into New Zealand. These birds are residents in the milder parts of their range only performing nomadic movements; however, populations from much of Asia migrate further south and west in winter as the waters freeze. Eurasian coots inhabit freshwater lakes, ponds, pools, creeks, rivers and river deltas, marshes, freshwater meadows, flooded grasslands, and freshwater, and saline lagoons.

22-9-2017 MONTE CORONA, VALENCIA - SPECKLED WOOD BUTTERFLY (Pararge aegeria)

The speckled wood (Pararge aegeria) is a butterfly found in and on the borders of woodland areas throughout much of the Palearctic realm. The background of the wings ranges from brown to orange, and the spots are either pale yellow, white, cream, or a tawny orange. The speckled wood feeds on a variety of grass species. The males of this species exhibit two types of mate locating behaviors: territorial defense and patrolling. The proportion of males exhibiting these two strategies changes based on ecological conditions. The monandrous female must choose which type of male can help her reproduce successfully. Her decision is heavily influenced by environmental conditions.

Occurs in woodland, gardens and hedgerows. Butterflies often perch in sunny spots, spiralling into the air to chase each other.

The aptly named Speckled Wood flies in partially shaded woodland with dappled sunlight. The male usually perches in a small pool of sunlight, from where it rises rapidly to intercept any intruder. Both sexes feed on honeydew in the treetops and are rarely seen feeding on flowers, except early and late in the year when aphid activity is low.

The range of this butterfly contracted during the late nineteenth and early twentieth centuries but has spread back since the 1920s. It has continued to spread over the past two decades, recolonizing many areas in eastern and northern England and Scotland.

22-9-2017 MONTE CORONA, VALENCIA - COMMON DARTER DRAGONFLY (FEMALE) (Sympetrum striolatum)

The common darter (Sympetrum striolatum) is a dragonfly of the family Libellulidae native to Eurasia. It is one of the most common dragonflies in Europe, occurring in a wide variety of water bodies, though with a preference for breeding in still water such as ponds and lakes. In the south of its range adults are on the wing all year round.

Sympetrum species are not easy to tell apart and in most areas more than one Sympetrum species will occur. Females and teneral individuals have light yellow thorax and abdomen. Males turn red as they mature. Females darken with age, becoming a dark chocolate brown, and sometimes develop a blue colouration to the bottom of the abdomen. The wings also develop a brown tinge with age. In all cases the legs have a cream or yellow stripe on a black background - this is a diagnostic feature of this species. The pterostigma of the females can be red, blue, pale blue or brown.

22-9-2017 MONTE CORONA, VALENCIA - SOUTHERN SKIMMER DRAGONFLY (Orthetrum brunneum)

Orthetrum brunneum, the southern skimmer, is a species of 'skimmers' belonging to the family Libellulidae.

Subspecies

Subspecies include:

Orthetrum brunneum var. brunneum (Fonscolombe, 1837) (Palearctic realm)

Orthetrum brunneum var. cycnos (Sélys, 1848) (Corsica and Sardinia) 

Distribution

This 'skimmer' is present in most of Europe and the range extends to Mongolia and North Africa.

It occurs in Afghanistan, Albania, Algeria, Andorra, Armenia, Austria, Belarus, Belgium, Bosnia and Herzegovina, Bulgaria, China, Croatia, Cyprus, Czech Republic, Egypt, France, Germany, Greece, Hungary, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Republic of Macedonia, Malta, Moldova, Montenegro, Netherlands, Poland, Portugal, Romania, Russia, Serbia; Slovakia, Slovenia, Spain, Switzerland, Turkey, and Ukraine.

This species mainly prefers small streams, canals and ditches, with shallow, fast warming water.

The adults grow up to 40–45 millimetres (1.6–1.8 in) long. Their dimensions on average are larger than in Orthetrum coerulescens.

The thorax and the abdomen are pale blue in males, yellowish-brown or greyish-brown in females. Young males are brownish. The abdomen is relatively flattened and shows a thin middorsal black line and distinct points on each segment. The wings are hyaline, with yellow or pale brown pterostigma. The wingspan reaches 66–70 millimetres (2.6–2.8 in).

Adults can be encountered from mid June through late August in the immediate vicinity of quiet rivers or close to stagnant and shallow waters, lying on a well sunny ground. Sexually mature males defend a 'territory' on the waterfront by making short inspection flights, in order to chase away other males.

These skimmers commonly mate at rest, usually on the ground. Female lays the eggs on the surface of shallow water, touching it only with her abdomen while flying, sometimes accompanied by the male, that keeps other males at a distance.

The larvae are ferocious predators. They live buried in fine soil material (fine sand, silt, etc.), in unshaded places in shallow water. They overwinter and develop in two or three years.

25-9-2017 DENIA COAST, ALICANTE - YELLOW LEGGED GULL (Larus michahellis)

The Yellow-legged Gull (Larus michahellis) is a large, robust seabird with a commanding presence. Its size can be quite variable, with the smallest females being scarcely larger than a Common Gull, and the largest males approaching the heft of a Great Black-backed Gull. Adults typically exhibit a grey back, a shade lighter than that of the Lesser Black-backed Gull, and their heads are notably whiter in the autumn months. A distinctive feature is their yellow legs, which give this species its common name.

When observing the Yellow-legged Gull, look for the yellow legs that contrast with the grey back and the white head, which becomes even whiter during the autumn. The wing tips are black with limited white spots, and adults have a red spot on the bill. The eye is surrounded by a red ring. Juveniles can be identified by their paler head, rump, and underparts, dark bill and eyes, and a black band on the tail.

This gull favors a variety of coastal environments, often nesting on sea cliffs, islands, and occasionally on buildings within urban settings. It is also known to breed on trees in some regions.

The Yellow-legged Gull has a breeding range centered around the Mediterranean Sea, extending to the Atlantic islands and coasts as far north as Brittany and west to the Azores. Its presence is also noted on the western side of the Black Sea.

The species is known for its adaptability, with many individuals remaining in the same area year-round, while others migrate to milder regions of western Europe or head south to areas such as Senegal and the Red Sea. Post-breeding dispersal can lead to increased numbers in regions like southern England from July to October.

The vocalizations of the Yellow-legged Gull are characterized by a loud, laughing call that is deeper and more nasal than that of the Herring Gull.

Breeding typically occurs in colonies, with nests constructed on the ground or cliff ledges. The nests are mounds of vegetation, and the species is known for its vigorous defense of its eggs, usually numbering three. Incubation lasts for 27–31 days, and fledging occurs after 35–40 days.

An opportunistic forager, the Yellow-legged Gull is omnivorous, feeding on a wide range of items from rubbish tips to field prey, coastal offerings, and even other seabirds' catches. Remarkably, during periods of food scarcity, such as the lockdown in Italy in 2020, these gulls have been observed preying on larger animals like rats and rock doves.

The Yellow-legged Gull is currently listed as Least Concern on the IUCN Red List, indicating that it does not face any immediate threat of extinction.

25-9-2017 DENIA COAST, ALICANTE - HOUSE SPARROW (FEMALE) (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.

25-9-2017 DENIA COAST, ALICANTE - OLD WORLD SWALLOWTAIL BUTTERFLY (Papilio machaon)

Papilio machaon, the Old World swallowtail, is a butterfly of the family Papilionidae. The butterfly is also known as the common yellow swallowtail or simply the swallowtail (a common name applied to all members of the family, but this species was the first to be given the name). It is the type species of the genus Papilio. This widespread species is found in much of the Palearctic (it is the only swallowtail in most of Europe) and in North America.

This species is named after Machaon (Ancient Greek: Μαχάων, romanized: Makháōn) a figure in Greek mythology. He was a son of Asclepius.

The imago typically has yellow wings with black vein markings, and a wingspan of 65–86 millimetres (2.6–3.4 in). The hindwings of both sexes have a pair of protruding tails which give the butterfly its common name from the resemblance to the birds of the same name. Just below each tail is one red and six blue eye spots.

In the caterpillar stage, P. machaon has a length of 45 millimetres (1.8 in). When young, the caterpillar resembles a bird dropping, giving it camouflage. The caterpillar also protects itself using a large orange fork which protrudes behind its head.

It can be distinguished from Papilio hospiton, which occurs sympatrically with it on Corsica and Sardinia, by the longer "tails" on the hindwings. It can be told apart from the Algerian species Papilio saharae only by counting the segments on the antennae.

This butterfly is present throughout the entire Palearctic region, ranging from Russia to China and Japan, (including the Himalayas and Taiwan), and across into Alaska, Canada, and the United States, and thus, is not restricted to the Old World, despite the common name. In Asia, it is reported as far south as Saudi Arabia, Oman, the high mountains of Yemen, Lebanon, Iran and Israel. In southern Asia, it occurs in Pakistan and Kashmir, northern India (Sikkim, to Assam, and Arunachal Pradesh), Nepal, Bhutan, and northern Myanmar.

This butterfly is widespread in Europe. In the United Kingdom, it is limited to a few areas in the Norfolk Broads of East Anglia. It is the UK's largest resident butterfly. The monarch (Danaus plexippus) is slightly larger, but is only a rare vagrant.

As P. machaon is widespread throughout Eurasia and often common, it is not threatened as a species. It is listed as "vulnerable" in the South Korean and Austrian Red Data Books, and in the Red Data Book of the former Soviet Union. In Armenia the species demonstrates stable population trend and is assessed as Least Concern.

In some countries, P. machaon and its subspecies are protected by law. Papilio machaon machaon is protected by law in six provinces of Austria, Czech Republic, Slovakia, Hungary, Romania, and Moldova. The species is protected in the United Kingdom, and subspecies verityi is protected in India.

The butterfly has a strong and fast flight, but frequently pauses to hover over flowering herbs and sip nectar. It frequents alpine meadows and hillsides, and males are fond of 'hilltopping', congregating near summits to compete for passing females. At lower elevations, it can be seen visiting gardens.

Unlike other swallowtails which specialise on Rutaceae, this species mostly feeds on plants of family Umbelliferae, females laying eggs singly. Milk parsley (also known as marsh hog's fennel) is normally the only food plant used by the caterpillars of the British subspecies. The food plants of the swallowtail in Europe, Asia, and North America are more varied than in the UK. It uses a wide variety of umbellifers including wild carrot (Daucus carota), wild angelica (Angelica sylvestris), fennel (Foeniculum vulgare), and hogweeds (Heracleum). In the Maltese Islands, the caterpillar feeds on plants such as rue (Ruta chalepensis) in addition to Umbelliferae such as fennel.

In Kashmir, the common yellow swallowtail, as Papilio machaon is called there, inhabits alpine meadows in the Himalayas occurring from 2,000 feet (610 m) in Kashmir valley to 16,000 ft (4,900 m) in the Garhwal Himalayas. In India, in Himachal Pradesh, it is found over 4,000 ft (1,200 m) only and in Sikkim over 8,000 ft (2,400 m) only.

At lower elevations, these butterflies fly from March to September; at higher elevations, they are limited by the short summer seasons.

The British subspecies P. m. brittanicus is less mobile than its European continental counterpart and stays within, or close by, its fenland habitat.

25-9-2017 DENIA COAST, ALICANTE - SCARCE SWALLOWTAIL BUTTERFLY (Iphiclides podalirius)

Iphiclides feisthamelii, the southern scarce swallowtail, southern swallowtail or Iberian scarce swallowtail, is a butterfly found in Italy, Slovenia, southern France, Spain, Portugal, Morocco, Algeria and Tunisia. It is sometimes considered a subspecies of I. podalirius.

The larva feeds on Prunus amygdalus (almond), P. persica (peach), P. insititia (a kind of plum), P. longipes, Pyrus communis (common pear), Malus domesticus (apple) and Crataegus oxyacantha.

This species is often considered merely a subspecies of the scarce swallowtail, though recent authors are increasingly counting it a separate species. Its distribution is restricted to the Iberian peninsula south of the Pyrenees. It is very similar to the scarce swallowtail but usually a more papery white, with noticeably more kite-shaped wings and a more distinct yellow line along the costa of the forewing. Another useful but not 100% diagnostic feature is the third bar from the wing base on the forewing, which is typically blunt on the vein, not tapered to a point.

Iberian scarce swallowtails may be seen very early in the year. The first pictures on this page were taken in February in Málaga, where the species was hilltopping along with many other butterflies. They fly throughout the year in two or three broods, hibernating as pupae.

After many years being considered a subspecies of the scarce swallowtail I. podalirius this taxon can now be accepted as a full species.

Identification & Similar species: Compared to the scarce swallowtail I. podalirius, this species has a white/ grey-white rather than yellowish ground colour, but sometimes with faint yellow in the female. Markings are also darker, at least in the spring brood. The differences are subtle...

Genetalia are reportedly slightly different and there is some differentiation in mitochondrial DNA.

Distribution & Flight: North Africa, Spain and southwest France. There may be overlap with the scarce swallowtail I. podalirius in some areas particularly as these are mobile butterflies. Flies from March or April to the end of summer in multiple broods.

Habitat & Behaviour: Diverse habitats: scrub, meadows, parks, gardens, coasts to mountains.

25-9-2017 DENIA COAST, ALICANTE - EUROPEAN SHAG (Phalacrocorax aristotelis)

The European shag, or common shag (Gulosus aristotelis), is a medium-large seabird with a distinctive yellow throat-patch. During the breeding season, adults sport a small crest. This species is characterized by its metallic green-tinged sheen and a longish tail, setting it apart from its relatives with a lighter build and a more slender bill.

To identify the European shag, look for a bird measuring 68 to 78 cm in length with a wingspan of 95 to 110 cm. The adult shag has a green sheen on its feathers and a yellow patch on its throat. The bill is lighter and narrower compared to the great cormorant. Juveniles have darker underparts, and the tail consists of 12 feathers, as opposed to the great cormorant's 14.

The European shag is a coastal bird, preferring rocky shores for breeding and nesting. It is rarely found inland, as it is adapted to life at sea.

This species breeds along the rocky coasts of western and southern Europe, southwest Asia, and north Africa. It mainly winters within its breeding range, except for the northernmost populations. The largest colony is found in the Cíes Islands, Spain.

The European shag is a remarkable diver, known to reach depths of up to 61 meters. It is predominantly a benthic feeder, sourcing its prey from the sea bottom. Shags are known to travel significant distances from their roosts to feed. They exhibit a strong diving technique, leaping from the water to gain momentum.

Breeding takes place on coastal cliffs, with nests constructed from seaweed or twigs, bound together with guano. The breeding season is extensive, starting as early as February and in some cases extending to May or later. Typically, three eggs are laid, and chicks are entirely dependent on parental warmth, as they hatch without down.

 

The European shag can be confused with the great cormorant but is differentiated by its smaller size, lighter build, thinner bill, and the presence of a crest and metallic sheen in breeding adults.

The European shag's diet is diverse, with a preference for sand eels. However, diet composition can vary with environmental conditions, such as ocean warming and windy weather, which can influence prey availability and foraging success.

The IUCN Red List classifies the European shag as Least Concern, indicating that it is not currently at significant risk of widespread decline.

25-9-2017 DENIA COAST, ALICANTE - BAND WINGED GRASSHOPPER (Genus Oedipoda)

Oedipoda is the type genus of grasshoppers, in the subfamily Oedipodinae, mostly from the Palaearctic realm. The type species is the European "blue-winged grasshopper", Oedipoda caerulescens.

25-9-2017 DENIA COAST, ALICANTE - BLACK HEADED GULL (Chroicocephalus ridibundus)

The black-headed gull (Chroicocephalus ridibundus) is a small, nimble gull with a wingspan ranging from 94 to 110 cm and a body length of 37 to 44 cm. It weighs between 190 and 400 grams. Despite its name, the adult's summer plumage features a chocolate-brown head, which can appear black from a distance. The body is pale grey, and the primary wing feathers are tipped with black. The bill and legs are a striking red. In winter, the brown head is replaced by a white one with dark spots. Juveniles are mottled with brown spots and have a black band on the tail. There is no sexual dimorphism in plumage.

In flight, the white leading edge of the wing is a distinctive field mark. The summer adult's brown head, red bill, and legs are key identifiers, while the winter plumage features two dark spots on the head. Juveniles can be recognized by their mottled brown pattern and black tail band.

This species nests in colonies on the ground in large reed beds, marshes, or islands within lakes. It is not pelagic and is seldom seen far from coasts.

The black-headed gull breeds across much of the Palearctic, including Europe and coastal eastern Canada. It is migratory, wintering further south, but some remain in the milder westernmost areas of Europe. It is also present in northeastern North America and occasionally seen as far south as Virginia and some Caribbean islands.

Highly gregarious in winter, the black-headed gull is an opportunistic feeder, consuming a wide range of food from insects to carrion. It is known for its "kree-ar" call and displays various behaviors such as eggshell removal from the nest, which is believed to reduce predation risk.

The black-headed gull is a vocal species, particularly in colonies. Its call is a familiar "kree-ar," and its scientific name suggests a laughing sound.

This gull takes two years to reach maturity. First-year birds can be distinguished by a black terminal tail band and a less developed dark hood in summer. Breeding occurs in colonies, and the species is known for its complex social behaviors, including begging coordination between siblings and conspecific brood parasitism.

The black-headed gull can be confused with the similar-looking Bonaparte's Gull in North America.

The diet includes insects, fish, seeds, worms, scraps, carrion, and invertebrates in ploughed fields. It feeds in towns and agricultural areas with equal relish.

The black-headed gull is listed as Least Concern on the IUCN Red List, indicating it is not currently at significant risk of widespread decline.

Individuals synchronize their vigilance activities with nearby conspecifics, depending on the distance between them.

The first recorded sighting in Australia occurred in 1991 at the Broome Sewage Ponds, marking a significant range expansion for the species.

The black-headed gull has been immortalized in Richard Adams' novel "Watership Down" as the character Kehaar and is the official bird of Tokyo, Japan.
