9-12-2021 CITY OF ARTS AND SCIENCES, VALENCIA - SOUTH AMERICAN SEA LION (Otaria flavescens)


The South American sea lion (Otaria flavescens, formerly Otaria byronia), also called the southern sea lion and the Patagonian sea lion, is a sea lion found on the western and southeastern coasts of South America. It is the only extant member of the genus Otaria, which also includes the extinct Otaria josefinae. The species is highly sexually dimorphic. Males have a large head and prominent mane. They mainly feed on fish and cephalopods and haul out on sand, gravel, rocky, or pebble beaches. Breeding males typically defend both territories and individual females, though this can vary. Less dominant males may try to achieve success by causing chaos in the group. The overall population of the species is considered stable, estimated at 265,000 animals.

The South American sea lion was classified as Phoca flavescens by George Shaw in 1800 and as Otaria byronia by Henri Marie Ducrotay de Blainville in 1820. The two nomenclatures were historically used interchangeably, but O. flavescens has become the preferred name. The species is also known by the common name "southern sea lion", although it is not preferred since the Australian sea lion and New Zealand sea lion also range in the Southern Hemisphere. Locally, it is known by several names, including león marino (sea lion) and lobo marino (sea wolf).


The South American sea lion is among the largest of and most sexually dimorphic of the eared seals. Males measure up to 3 m (9.8 ft) in length with a weight of 350 kg (770 lb) while females reach a length 2 m (6 ft 7 in) and reach 150 kg (330 lb) in weight. Pups are born 0.86 m (2 ft 10 in) long and weigh 12–15 kg (26–33 lb). Size differences between the sexes exists in both newborns and juveniles.

Adult males have large heads with short, upturned snouts and long manes which reach the shoulders. The fur is mainly brownish with adult males being dark brown and females being nearly yellowish. Pups are born black but become reddish-brown after their first molt.

The South American sea lion is found along the coasts and offshore islands of South America, from Peru south to Cape Horn and then north to southern Brazil. Notable breeding colonies include Lobos Island, Uruguay; Peninsula Valdes, Argentina; Beagle Channel, and the Falkland Islands. Some individuals wander as far north as southern Ecuador, although apparently they never bred there.

12-12-2021 LLUTXENT, VALENCIA - EURASIAN BLACKCAP (MALE) (Sylvia atricapilla)


The Eurasian blackcap, Sylvia atricapilla, is a common and widespread typical warbler known for its distinctive cap and melodious song. The species exhibits sexual dimorphism with males sporting a black cap and females a chestnut one. The upperparts are generally olive-grey, while the underparts are pale grey. This bird is small and agile, measuring around 13 cm in length with a wingspan of 7–8 cm.

Males can be identified by their black caps and light grey underparts, while females have a reddish-brown cap and a slightly browner hue to their grey upperparts. Juveniles resemble females but have a rufous tinge to their upperparts and a more olive tone on the breast and flanks. The blackcap's tail is dark grey with an olive edge to each feather, and it has a grey bill and legs with a reddish-brown iris.


The blackcap favors mature deciduous woodlands with a well-developed understory. It also occupies parks, large gardens, and overgrown hedges, provided there are tall trees for songposts and dense shrubs for nesting.

Blackcaps are territorial during the breeding season, with males establishing and defending their territories through song and display. They are mainly monogamous and may raise one to two broods per season. The species is known for its leap-frog migration pattern, where northern populations migrate further south than those from the Mediterranean.


This warbler breeds across much of Europe, western Asia, and northwestern Africa. It is a partial migrant, with northern populations wintering in northwestern Europe, around the Mediterranean, and in tropical Africa. Some have adapted to wintering in British and Irish gardens.


12-12-2021 LLUTXENT, VALENCIA - EUROPEAN STARLING (Sturnus vulgaris)


The Common starling (Sturnus vulgaris) is a medium-sized passerine bird in the starling family, Sturnidae. It is a noisy bird, especially in communal roosts and other gregarious situations, with an unmusical but varied song. Its gift for mimicry has been noted in literature including the Mabinogion and the works of Pliny the Elder and William Shakespeare.

The Сommon starling is a medium-sized bird. It has glossy black plumage with a metallic sheen, which is speckled with white at some times of the year. The legs are pink and the bill is black in winter and yellow in summer. Juveniles are grey-brown and by their first winter resemble adults though often retaining some brown juvenile feathering, especially on the head. They can usually be sexed by the color of the irises, rich brown in males, mouse-brown, or grey in females.


Common starlings are native to Eurasia and are found throughout Europe, northern Africa (from Morocco to Egypt), India (mainly in the north but regularly extending further south and extending into the Maldives) Nepal, the Middle East including Syria, Iran, and Iraq and north-western China. Common starlings in the south and west of Europe are mainly resident, although other populations migrate from regions where the winter is harsh. Most birds from northern Europe, Russia, and Ukraine migrate southwestwards or southeastwards. In the autumn, when immigrants are arriving from eastern Europe, many of Britain's common starlings are setting off for Iberia and North Africa. Common starlings prefer urban or suburban areas, reedbeds, grassy areas such as farmland, grazing pastures, playing fields, golf courses, and airfields where short grass makes foraging easy. They occasionally inhabit open forests and woodlands and are sometimes found in shrubby areas. These birds are also found in coastal areas, where they nest and roost on cliffs and forage amongst the seaweed.

12-12-2021 LLUTXENT, VALENCIA - EURASIAN BLACKCAP (FEMALE) (Sylvia atricapilla)


The Eurasian blackcap (Sylvia atricapilla) is a common and widespread warbler that breeds in much of Europe, western Asia, and northwestern Africa. Its rich and varied song has led to the blackcap being described as the "mock nightingale" and it has been featured in literature, films, and music.

The Eurasian blackcap is mainly grey in color with distinct male and female plumages. The adult male has olive-grey upperparts, other than a paler grey nape and a neat black cap on the head. The underparts are light grey, becoming silvery white on the chin, throat, and upper breast. The tail is dark grey, with an olive tint to the outer edge of each feather. The bill and long legs are grey, and the iris is reddish brown. The female resembles the male but has a reddish-brown cap and a slightly browner tone to the grey of the upperparts. Juveniles are similar to the female, but their upperparts have a slight rufous tinge, and the breast and flanks have a more olive tone; young males have darker brown cap than their female counterparts.


Eurasian blackcaps are very active birds. They are usually found singly but may form loose groups during migration. They feed by the day mainly picking prey off foliage and twigs, but may occasionally hover, flycatch or feed on the ground. Blackcaps eat a wide range of small fruit and squeeze out any seeds on a branch before consuming the pulp. They defend good winter food sources, and at garden feeding stations they don't hesitate to repel competitors as large as starlings and blackbirds. Eurasian blackcaps are known for their beautiful loud song. The males' song is a rich musical warbling, often ending in a loud high-pitched crescendo, which is given in bursts of up to 30 seconds. In some geographically isolated areas, such as islands, peninsulas, and valleys in the Alps, males sing a simpler fluting song. The main call of Eurasian blackcaps is a hard 'tac-tac', like stones knocking together, and other vocalizations include a squeaking sweet alarm, and a low-pitched trill. Blackcaps may sometimes mimic the song of other birds, especially preferring to copy the garden warbler and the common nightingale.

12-12-2021 LLUTXENT, VALENCIA - EUROPEAN ROBIN (Erithacus rubecula)


The European robin (Erithacus rubecula), known simply as the robin or robin redbreast in Great Britain and Ireland, is a small insectivorous passerine bird, a member of the chat subfamily of the Old World flycatcher family. It is a plucky little bird, with a length of about 12.5–14.0 cm and a weight of 16–22 g. Both sexes are similarly adorned with an orange breast and face, lined with grey, brown upper-parts, and a whitish belly.

Adult robins can be identified by their orange breast and face, bordered by a bluish-grey on the sides of the neck and chest. The upperparts are brownish, or olive-tinged in British birds, and the belly is whitish. The bill and eyes are black. Juvenile robins are distinguishable by their spotted brown and white plumage, with patches of orange gradually appearing as they mature.

The European robin is a bird of diverse habitats, found in woodlands, gardens, and parks across its range. It is particularly associated with areas where the soil is dug or disturbed, allowing it easy access This bird has a wide distribution across Europe, extending east to Western Siberia and south to North Africa. It is sedentary in most of its range except the far north, where it is migratory.

The robin is diurnal and is known for its boldness in human presence, often seen investigating gardeners at work. It is territorial, with males known to fiercely defend their territory. The robin's diet is primarily composed of insects and worms, but it will also consume berries and fruit, especially in autumn and winter.


The robin's song is a delightful fluting warble, more plaintive during the winter months. Both sexes sing, with the male's song typically starting before dawn and ending after dusk. Urban robins may sing at night, possibly to avoid noise pollution during the day.

Robins are versatile in their choice of nesting sites, often opting for unusual locations such as nooks in machinery or even discarded clothing. They typically lay two or three clutches of eggs per season, with the eggs being cream, buff, or white and speckled with reddish-brown.

Robins primarily feed on insects, spiders, and worms. During colder months, their diet is supplemented with berries and fruit. They are also known to visit bird tables for seed mixtures and suet.

The European robin is classified as Least Concern by the IUCN, with a stable and possibly increasing population. It does not face any significant threats that would warrant concern for its long-term survival.

9-12-2021 CITY OF ARTS AND SCIENCES, VALENCIA - GENTOO PENGUIN (Pygoscelis papua)


The gentoo penguin (/ˈdʒɛntuː/ JEN-too) (Pygoscelis papua) is a penguin species (or possibly a species complex) in the genus Pygoscelis, most closely related to the Adélie penguin (P. adeliae) and the Chinstrap penguin (P. antarcticus). The earliest scientific description was made in 1781 by Johann Reinhold Forster with a type locality in the Falkland Islands. The species calls in a variety of ways, but the most frequently heard is a loud, trumpeting call, emitted with the head thrown back.

The application of "gentoo" to the penguin is unclear. Gentoo was an Anglo-Indian term to distinguish Hindus from Muslims. The English term may have originated from the Portuguese gentio ("pagan, gentile"). Some speculate that the white patch on the bird's head was thought to resemble a turban.


It may also be a variation of another name for this bird, "Johnny penguin", with Johnny being the English counterpart of the Spanish nickname Juanito and sounding vaguely like gentoo. The Johnny rook, a predator, is likely named after the Johnny penguin.

The specific name papua is a misnomer; in the original description, Johann Reinhold Forster, a naturalist who had circumnavigated the world with Captain James Cook, mistakenly assumed that the species occurred in Papua (New Guinea), the closest gentoos being over 6,000 km (3,700 mi) to the south (on Macquarie Island). No penguins are found in New Guinea. Others trace the error to a "possibly fraudulent claim" in 1776 by French naturalist Pierre Sonnerat, who also alleged a Papuan location for the king penguin despite never having been to the island himself.


The gentoo penguin is easily recognised by the broad, white stripe extending like a bonnet across the top of its head and its bright orange-red bill. It has pale whitish-pink, webbed feet and a relatively long tail – the most prominent tail of all penguin species. Chicks have grey backs with white fronts. As the gentoo penguin waddles along on land, its tail sticks out behind, sweeping from side to side, hence the scientific name Pygoscelis, which means "rump-tailed".

Gentoo penguins can reach a length of 70 to 90 cm (28 to 35 in), making them the third-largest species of penguin after the emperor penguin and the king penguin. Males have a maximum weight around 8.5 kg (19 lb) just before moulting and a minimum weight of about 4.9 kg (11 lb) just before mating. For females, the maximum weight is 8.2 kg (18 lb) just before moulting, but their weight drops to as little as 4.5 kg (9.9 lb) when guarding the chicks in the nest. Birds from the north are on average 700 g (1.5 lb) heavier and 10 cm (3.9 in) longer than the southern birds. Southern gentoo penguins reach 75–80 cm (30–31 in) in length. They are the fastest underwater swimmers of all penguins, reaching speeds up to 36 km/h (22 mph). Gentoos are well adapted to frigid and harsh climates.

9-12-2021 CITY OF ARTS AND SCIENCES, VALENCIA - BLACK WINGED STILT (JUVENILE) (Himantopus himantopus)




9-12-2021 CITY OF ARTS AND SCIENCES, VALENCIA - EUROPEAN MOORHEN (Gallinula chloropus)


The common moorhen, known scientifically as Gallinula chloropus, is a bird of the rail family, Rallidae. It is a bird of striking appearance, with a mix of black and brown plumage, a white under-tail, and white streaks along its flanks. Its legs are a vibrant yellow, and it sports a distinctive red frontal shield. The bill is a matching red with a yellow tip. Juveniles are a duller brown and do not have the red shield.

Adult moorhens can be identified by their red frontal shield, which has a rounded top and fairly parallel sides. The tailward margin of the red unfeathered area is smoothly curved. Their yellow legs and the combination of their black and brown plumage with white markings make them quite distinctive. The young are browner and lack the red shield, making them less conspicuous.

The common moorhen is found in a variety of wetland habitats, including marshes, ponds, canals, and lakes that are rich in vegetation. It is also known to inhabit city parks with suitable water bodies.

This species has a broad distribution across many parts of the Old World. It is not found in polar regions or many tropical rainforests but is otherwise widespread, often being the most common rail species in its range.

9-12-2021 CITY OF ARTS AND SCIENCES, VALENCIA - WESTERN CATTLE EGRET (Bubulcus ibis ssp. ibis)


The western cattle egret (Bubulcus ibis) is a species of heron (family Ardeidae) found in the tropics, subtropics and warm temperate zones. Most taxonomic authorities lump this species and the eastern cattle egret together (called the cattle egret), but some (including the International Ornithologists' Union) separate them. Despite the similarities in plumage to the egrets of the genus Egretta, it is more closely related to the herons of Ardea. Originally native to parts of Asia, Africa and Europe, it has undergone a rapid expansion in its distribution and successfully colonised much of the rest of the world in the last century.

It is a white bird adorned with buff plumes in the breeding season. It nests in colonies, usually near bodies of water and often with other wading birds. The nest is a platform of sticks in trees or shrubs. Western cattle egrets exploit drier and open habitats more than other heron species. Their feeding habitats include seasonally inundated grasslands, pastures, farmlands, wetlands and rice paddies. They often accompany cattle or other large mammals, catching insect and small vertebrate prey disturbed by these animals. Some populations of the cattle egret are migratory and others show post-breeding dispersal.

The adult cattle egret has few predators, but birds or mammals may raid its nests, and chicks may be lost to starvation, calcium deficiency or disturbance from other large birds. This species maintains a special relationship with cattle, which extends to other large grazing mammals; wider human farming is believed to be a major cause of their suddenly expanded range. The cattle egret removes ticks and flies from cattle and consumes them. This benefits both species, but it has been implicated in the spread of tick-borne animal diseases.

The cattle egret has undergone one of the most rapid and wide reaching natural expansions of any bird species. It was originally native to parts of Southern Spain and Portugal, tropical and subtropical Africa and humid tropical and western Asia. In the end of the 19th century it began expanding its range into southern Africa, first breeding in the Cape Province in 1908. Cattle egrets were first sighted in the Americas on the boundary of Guiana and Suriname in 1877, having apparently flown across the Atlantic Ocean. It was not until the 1930s that the species is thought to have become established in that area.

9-12-2021 CITY OF ARTS AND SCIENCES, VALENCIA - COMPASS JELLYFISH (Chrysaora hysoscella)


Chrysaora hysoscella, the compass jellyfish, is a common species of jellyfish that inhabits coastal waters in temperate regions of the northeastern Atlantic Ocean, including the North Sea and Mediterranean Sea. In the past it was also recorded in the southeastern Atlantic, including South Africa, but this was caused by confusion with close relatives; C. africana, C. fulgida and an undescribed species tentatively referred to as "C. agulhensis".

It is a true jellyfish displaying radial symmetry with distinct brown markings shaped like elongated V's on its bell. C. hysoscella adults are highly susceptible to the parasite Hyperia medusarum, but this has had no significant effects on the population. This organism has a benthic polyp stage before developing into a pelagic adult medusae. Compass jellyfish consume a variety of marine invertebrates and plankton and are preyed on by very few. C. hysoscella contribute to the global issue of jellyfish overpopulation which is concerning to humans for various reasons including recreational interference, economic turmoil for fishing communities, and depleted fish resources.


As an adult, the bell of the compass jellyfish typically has a diameter of 15–25 cm (5.9–9.8 in). It usually has 16 brown elongated V-shaped markings on the translucent yellow-white bell. The markings surround a central brown spot and resemble the face of a compass, hence the common name compass jellyfish. Juveniles on the other hand lack the compass pattern, they appear white and polka dotted with a reddish fringe on the edge of their bell.

It is usually colored yellowish white, with some brown. Its 24 tentacles are arranged in eight groups of three. Each tentacle has stinging cells for capturing prey and defense from predators. A sense organ is located between each group of tentacles, which can perceive changes in light and helps the jellyfish determine and maintain its position in the water column. It has 4 oral arms that can be distinguished from the tentacles because the arms are noticeably longer and have a folded, frilly appearance. These arms are used to facilitate transfer of captured prey from the tentacles to the mouth which is between the oral arms at the center of the underside of the bell.


The compass jellyfish is found in coastal waters of the northeast Atlantic, including the Celtic, Irish, North and Mediterranean Seas. They inhabit these waters mostly at the top of the water column, and although they inhabit shallow water, they move up and down in the water column often ranging from surface waters to just above the seabed. They are rarely found deeper than 30 m from the surface.

Compass jellyfish are carnivores, consuming other marine invertebrates and plankton.They feed on a variety of benthic and pelagic organisms including but not limited to: dinoflagellates, copepods, crustacean eggs, larval fish, and chaetognaths. They stun and capture their prey with stinging cells on their tentacles. The oral arms facilitate movement of captured prey into the oral opening. Compass jellyfish have very few predators. They are known to be consumed by the leatherback sea turtle and ocean sunfish.

Like other Scyphozoans, Chrysaora hysoscella undergo metamorphosis as the organism develops and experiences a polyp and then medusa form. Females release planular larvae which swim to find a suitable place to settle. The planulae attach to a benthic substrate and develop into a sessile polyp which releases immature medusae through asexual reproduction called strobilation. Chrysaora hysoscella function as a male upon maturity and then develop female gametes, meaning this organism is protandrously hermaphroditic.

9-12-2021 CITY OF ARTS AND SCIENCES, VALENCIA - WHITE HEADED DUCK (MALE) (Oxyura leucocephala)


The White-headed Duck, Oxyura leucocephala, presents a striking figure with its distinctive plumage and stout build. Males are adorned with a white head contrasted by a black crown, a blue bill, and a body cloaked in shades of reddish-grey. Females, on the other hand, exhibit a more subdued palette with a dark bill and less vibrant colouring.

Upon encountering this species, one can identify the male by its white head, black cap, and neck, and a blue bill, while the female can be recognized by her grey-brown body, white face, and darker bill and cap. These ducks measure between 43–48 cm in length and weigh approximately 580–750 g.

9-12-2021 CITY OF ARTS AND SCIENCES, VALENCIA - CHILOE WIGEON (Mareca sibilatrix)


The Chiloé wigeon (Mareca sibilatrix), also known as the southern wigeon, is one of three extant species of wigeon in the genus Mareca of the dabbling duck subfamily. This bird is indigenous to the southern part of South America, including the Chiloé Archipelago, from which it gets its name. In its native range, it is called the pato overo ("piebald duck") or pato real ("royal duck"), although the latter name also refers to the Muscovy in the wild. Its specific epithet, sibilatrix, means 'whistler', referring to the bird's call.

The Chiloé wigeon has a body length of 46 to 56 cm (18 to 22 in) and a wingspan of 75 to 86 cm (30 to 34 in). The wing length is about 25 cm (9.8 in) and the weight is approximately 800 g (28 oz).[2][3]

This bird has an iridescent green-blue cap on its head, and a bluish gray bill with a black tip. The cheeks and forehead are white, the eyes are dark brown, and there is a white auricular patch. The neck and occipital part of the head are black. The breast is barred black and white and the plumage of the wings is gray and white. The flanks of males are rust colored, and light brown on females. The legs and feet are gray.


Sexual dimorphism is relatively subtle in this species of wigeon. Males are usually somewhat larger and heavier, and with somewhat brighter plumage and more strongly pronounced iridescence of the cap. Apart from these features, it can be difficult to distinguish the two sexes. Juveniles resemble adult birds, but the rust coloring on the flanks is diminished or absent.

This duck is indigenous to the southern part of South America, where it is found on freshwater lakes, marshes, shallow lagoons and slow flowing rivers. Vagrants have been observed in South Georgia, South Orkney and the South Shetland Islands.

It breeds primarily in Argentina, Uruguay, and Chile. The northern border of the breeding range is in Argentina at 36° S and Chile at 40° S. It also breeds sparingly in the Falkland Islands. It migrates to southeastern Brazil for the winter.

It was first introduced to Europe in 1870; it soon bred in zoos.


Because the Chiloé wigeon is widely distributed and has a large, stable wild population, it is categorized as least concern by the IUCN.

The Chiloé wigeon displays a variety of behaviors depending on habitat. It is an omnivore, feeding predominantly on aquatic plants and grass, and occasionally coastal algae.

This monogamous species breeds in the austral spring, between September and December. Pairs inhabit very small breeding territories, building their nests in grasses and under bushes. The female lays eight to ten white or cream-colored eggs. After a gestation period of approximately 24–25 days the ducklings are born. The father helps raise the ducklings; however, he leaves the family after the offspring molt.

Captive hybrids with the Philippine Duck (Anas luzonica) have been described

9-12-2021 CITY OF ARTS AND SCIENCES, VALENCIA - GREAT WHITE PELICAN (Pelecanus onocrotalus)


The great white pelican (Pelecanus onocrotalus), also known as the eastern white pelican (in contrast to the western pelican of the Americas), rosy pelican or simply white pelican, is a bird in the pelican family. It breeds from southeastern Europe through Asia and Africa, in swamps and shallow lakes.

The great white pelican has been rated as a species of least concern on the IUCN Red List of Endangered Species (IUCN). It is listed under Appendix I of the Convention on the Conservation of Migratory Species of Wild Animals, Annexure I under the EU Birds Directive on the Conservation of Wild Birds, and Appendix II of the Berne Convention on the Conservation of European Wildlife and Natural Habitats. It is also listed within 108 Special Protection Areas in the European Union. It occurs within 43 Important Bird Areas (IBAs) in its European range. It is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) is applied.


The great white pelican was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae under the current binomial name Pelecanus onocrotalus. The species is treated as monotypic: no subspecies are recognised. The specific epithet onocrotalus is Latin meaning "pelican"., itself derived from Hellenistic Greek: ὀνοκρόταλος : onokrótalos, literally, "one who brays like a donkey," from ὄνος : ónos "donkey", and κρόταλον : krótalon "clapper" in reference to its harsh mating calls.


The great white pelican is a huge bird—only the Dalmatian pelican is, on average, larger among pelicans. It measures 140 to 180 cm (55 to 71 in) in length with a 28.9 to 47.1 cm (11.4 to 18.5 in) enormous pink and yellow bill, and a dull pale-yellow gular pouch. The wingspan measures 226 to 360 cm (7 ft 5 in to 11 ft 10 in), the latter measurement being the highest among extant flying animals outside of the great albatross. The adult male measures about 175 cm (69 in) in length; it weighs from 9 to 15 kg (20 to 33 lb) and larger races from the Palaearctic are usually around 11 kg (24 lb), with few exceeding 13 kg (29 lb). It has a bill measuring 34.7 to 47.1 cm (13.7 to 18.5 in). The female measures about 148 cm (58 in) in length, and is considerably less bulky, weighing 5.4 to 9 kg (12 to 20 lb), and has a bill that measures 28.9 to 40.0 cm (11.4 to 15.7 in) in length. In Lake Edward, Uganda, the average weight of 52 males was found to be 11.45 kg (25.2 lb) and in 22 females it was 7.59 kg (16.7 lb). In South Africa, the average weight of males was 9.6 kg (21 lb) and of females was 6.9 kg (15 lb). 


Thus the sexual dimorphism is especially pronounced in this species (perhaps the greatest known in any extant pelican), as at times the male can average more than 30% more massive than the female. The great white pelican rivals the kori bustard, which has even more pronounced sexual dimorphism, as the heaviest flying bird to reside in Africa (both averaging perhaps slightly heavier than the cape vulture and the wattled crane). There are a small few slightly heavier flying birds in the Eurasian portions of the range. Among standard measurements, the wing chord is 60 to 73 cm (24 to 29 in), the tail 16 to 21 cm (6.3 to 8.3 in), and the tarsus 13 to 14.9 cm (5.1 to 5.9 in) long. Standard measurements from different areas indicate that pelicans from the Western Palaearctic are somewhat larger than those from Asia and Africa.


The male has a downward bend in the neck and the female has a shorter, straighter beak. The plumage is predominantly white except on remiges, with a faint pink tinge on the neck and a yellowish base on the foreneck. The primary feathers are black, with white shafts at the bases, occasionally with paler tips and narrow fringes. The secondary feathers are also black, but with a whitish fringe. The upperwing coverts, underwing coverts, and tertials are white. The forehead is swollen and pinkish skin surrounds the bare, dark eyes having brown-red to dark brown irides. It has fleshy-yellow legs and pointed forehead-feathers where meeting the culmen. In breeding season, the male has pinkish skin while the female has orangey skin on its face. The bill is mostly bluish grey, with a red tip, reddish maxilla edges, and a cream-yellow to yolk-yellow gular pouch. The white plumage becomes tinged-pink with a yellow patch on the breast, and the body is tinged yellowish-rosy. It also has a short, shaggy crest on the nape. 


The white covert feathers contrast with the solid black primary and secondary feathers. The legs are yellow-flesh to pinkish orange. Both male and female are similar, but the female is smaller and has brighter orange facial skin in the breeding season.
The juvenile has darker, brownish underparts that are palest at the rump, center of the belly, and uppertail coverts. The underwing coverts are mostly dull-white, but the greater coverts are dark and there is a dark brownish bar over the lesser coverts. The rear tertials upperwing coverts mostly have paler tips with a silvery-grey tinge on the greater secondary coverts and tertials. It has dark flight feathers, and brown-edged wings. The head, neck, and upperparts, including the upperwing coverts, are mostly brown—this is the darkest part of the neck. The facial skin and the bill, including its gular pouch, are greyish to dusky greyish. The forehead, rump, and abdomen are white, and its legs and feet are grey. Its blackish tail occasionally has a silvery-grey tinge. Its underparts and back are initially browner and darker than those of the Dalmatian pelican, and the underwing is strongly patterned, similar to the juvenile brown pelican.


The great white pelican is distinguished from all other pelicans by its plumage. Its face is naked and the feathering on its forehead tapers to a fine point, whereas other species are completely feathered. In flight, the white underwing with black remiges of the adult are similar only to those of the American white pelican (P. erythrorhynchos), but the latter has white inner secondary feathers. It differs from the Dalmatian pelican in its pure white – rather than greyish-white – plumage, a bare pink facial patch around the eye, and pinkish legs. The spot-billed pelican (P. philippensis) of Asia is slightly smaller than the great white pelican, with greyish tinged white plumage, and a paler, duller-colored bill. Similarly, the pink-backed pelican (P. rufescens) is smaller, with brownish-grey plumage, a light pink to off-grey bill, and a pinkish wash on the back.

The bird is mostly silent but has a variety of low-pitched lowing, grunting, and growling calls. The flight call is a deep, quiet croak., while at breeding colonies, it gives deep moooo calls.


The great white pelican mainly eats fish. It leaves its roost to feed early in the morning and may fly over 100 km (62 mi) in search of food, as has been observed in Chad and in Mogode, Cameroon. It needs from 0.9 to 1.4 kg (2.0 to 3.1 lb) of fish every day, which corresponds to around 28,000,000 kg (62,000,000 lb) annual fish consumption at the largest colony of the great white pelican, on Tanzania's Lake Rukwa (with almost 75,000 birds). 

Fish targeted are usually fairly large ones, in the 500–600 g (1.1–1.3 lb) weight range and up to 1.8 kg (4.0 lb), and are taken based on regional abundance. Common carp are preferred in Europe, mullets in China, and Arabian toothcarp in India. In Africa, often the commonest cichlids, including many species in the Haplochromis and Tilapia genera, seem to be preferred.

The pelican's pouch serves simply as a scoop. As the pelican pushes its bill underwater, the lower bill bows out, creating a large pouch which fills with water and fish. As it lifts its head, the pouch contracts, forcing out the water but retaining the fish. A group of 6 to 8 great white pelicans gather in a horseshoe formation in water to feed together. They dip their bills in unison, creating a circle of open pouches, ready to trap every fish in the area. Most feeding is cooperative and done in groups, especially in shallow waters where fish schools can be corralled easily, though they may also forage alone as well.

9-12-2021 CITY OF ARTS AND SCIENCES, VALENCIA - STRIATED HERON (Butorides striata)


The striated heron (Butorides striata ) also known as mangrove heron, little heron or green-backed heron, is a small heron, about 44 cm tall. Striated herons are mostly non-migratory and noted for some interesting behavioral traits. Their breeding habitat is small wetlands in the Old World tropics from west Africa to Japan and Australia, and in South America and the Caribbean. Vagrants have been recorded on Oceanic islands, such as Chuuk and Yap in the Federated States of Micronesia, the Marianas and Palau; the bird recorded on Yap on February 25, 1991, was from a continental Asian rather than from a Melanesian population, while the origin of the bird seen on Palau on May 3, 2005 was not clear.

This bird was long considered to be conspecific with the closely related North American species, the green heron, which is now usually separated as B. virescens, as well as the lava heron of the Galápagos Islands (now B. sundevalli, but often included in B. striata, e.g. by BirdLife International); collectively they were called "green-backed herons".


The bird can also be found in Bolivia around the town of Riberalta in the Beni Department and specifically in the Aquicuana Reserve.

Adults have a blue-grey back and wings, white underparts, a black cap, a dark line extends from the bill to under the eye and short yellow legs. Juveniles are browner above and streaked below.

These birds stand still at the water's edge and wait to ambush prey, but are easier to see than many small heron species. They mainly eat small fish, frogs and aquatic insects. They sometimes use bait, dropping a feather or leaf carefully on the water surface and picking fish that come to investigate.

They nest in a platform of sticks measuring between 20–40 cm long and 0.5–5 mm thick. The entire nest measures some 40–50 cm wide and 8–10 cm high outside, with an inner depression 20 cm wide and 4–5 cm deep. It is usually built in not too high off the ground in shrubs or trees but sometimes in sheltered locations on the ground, and often near water. The clutch is 2–5 eggs, which are pale blue and measure around 36 by 28 mm.

An adult bird was once observed in a peculiar and mysterious behavior: while on the nest, it would grab a stick in its bill and make a rapid back-and-forth motion with the head, like a sewing machine's needle. The significance of this behavior is completely unknown: While such movements occur in many other nesting birds where they seem to compact the nest, move the eggs, or dislodge parasites, neither seems to have been the case in this particular striated heron.


9-12-2021 CITY OF ARTS AND SCIENCES, VALENCIA - SCARLET IBIS (Eudocimus ruber)


The scarlet ibis (Eudocimus ruber) is a species of ibis in the bird family Threskiornithidae. It inhabits tropical South America and part of the Caribbean. In form, it resembles most of the other twenty-seven extant species of ibis, but its remarkably brilliant scarlet coloration makes it unmistakable. It is one of the two national birds of Trinidad and Tobago, and its Tupi–Guarani name, guará, is part of the name of several municipalities along the coast of Brazil.

This medium-sized wader is a hardy, numerous, and prolific bird, and it has protected status around the world. Its IUCN status is Least Concern. The legitimacy of Eudocimus ruber as a biological classification, however, is in dispute. Traditional Linnaean taxonomy classifies it as a unique species, but some scientists have moved to reclassify it as a subspecies of a more general American ibis species, along with its close relative, the American white ibis (Eudocimus albus).


The range of the scarlet ibis is very large, and colonies are found throughout vast areas of South America and the Caribbean islands. Native flocks exist in Brazil; Colombia; French Guiana; Guyana; Suriname; and Venezuela, as well as the islands of the Netherlands Antilles, and Trinidad and Tobago. Flocks gather in wetlands and other marshy habitats, including mud flats, shoreline and rainforest. Outlying colonies have been identified in the coastal areas of the states of Espírito Santo, Rio de Janeiro, São Paulo (for example in the Santos-Cubatão mangroves of the Baixada Santista district), Paraná and Santa Catarina. In recent years, bird colonies can be seen as far south as in the coastal areas of Joinville and the island of São Francisco do Sul.

9-12-2021 CITY OF ARTS AND SCIENCES, VALENCIA - EURASIAN WIGEON (FEMALE) (Mareca penelope)


The Eurasian wigeon or European wigeon (Mareca penelope), also known as the widgeon or wigeon, is one of three extant species of wigeon in the dabbling duck genus Mareca. It is common and widespread within its Palearctic range.

This dabbling duck is 42–52 cm (17–20 in) long with a 71–80 cm (28–31 in) wingspan, and a weight of 500–1,073 g (1–2 lb). The breeding male has grey flanks and back, with a black rear end, a dark green speculum and a brilliant white patch on upper wings, visible in flight or at rest. It has a pink breast, white belly, and a chestnut head with a creamy crown. In non-breeding (eclipse) plumage, the drake looks more like the female. The female is light brown, with plumage similar to that of a female American wigeon. It can be distinguished from most other ducks, apart from American wigeon, by its shape. However, that species has a paler head and white axillaries on the underwings. The female can be a rufous morph with a redder head, and a gray morph with a grayer head.

9-12-2021 CITY OF ARTS AND SCIENCES, VALENCIA - DEMOISELLE CRANE (Anthropoides virgo)



The demoiselle crane (Grus virgo) is a species of crane found in central Eurosiberia, ranging from the Black Sea to Mongolia and Northeast China. There is also a small breeding population in Turkey. These cranes are migratory birds. Birds from western Eurasia will spend the winter in Africa while the birds from Asia, Mongolia and China will spend the winter in the Indian subcontinent. The bird is symbolically significant in the culture of India, where it is known as Koonj or Kurjaa.


The demoiselle crane lives in a variety of different environments, including desert areas and numerous types of grasslands (flooded, mountain, temperate and tropical grassland) which are often within a few hundred metres of streams or lakes. However, when nesting, they prefer patchy areas of vegetation which is tall enough to conceal them and their nests, yet short enough to allow them look out for predators whilst incubating their eggs.

Demoiselle cranes have to take one of the toughest migrations in the world. In late August through September, they gather in flocks of up to 400 individuals and prepare for their flight to their winter range. During their migratory flight south, demoiselles fly like all cranes, with their head and neck straight forward and their feet and legs straight behind, reaching altitudes of 16,000–26,000 feet (4,900–7,900 metres). Along their arduous journey they have to cross the Himalayan mountains to get to their over-wintering grounds in India. Many die from fatigue, hunger and predation from golden eagles. Simpler, lower routes are possible, such as crossing the range via the Khyber Pass. However, their presently preferred route has been hard-wired by countless cycles of migration. At their wintering grounds, demoiselles have been observed flocking with common cranes, their combined totals reaching up to 20,000 individuals. Demoiselles maintain separate social groups within the larger flock. In March and April, they begin their long spring journey back to their northern nesting grounds.

In Khichan, Rajasthan in India, villagers feed the cranes on their migration and these large congregations have become an annual spectacle.



9-12-2021 CITY OF ARTS AND SCIENCES, VALENCIA - 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.

9-12-2021 CITY OF ARTS AND SCIENCES, VALENCIA - ROSEATE SPOONBILL (Platalea ajaja)


The roseate spoonbill (Platalea ajaja) is a gregarious wading bird of the ibis and spoonbill family, Threskiornithidae. It is a resident breeder in both South and North America. The roseate spoonbill's pink color is diet-derived, consisting of the carotenoid pigment canthaxanthin, like the American flamingo.

The roseate spoonbill is sometimes placed in its own genus – Ajaia. A 2010 study of mitochondrial DNA of the spoonbills by Chesser and colleagues found that the roseate and yellow-billed spoonbills were each other's closest relatives, and the two were descended from an early offshoot from the ancestors of the other four spoonbill species. They felt the genetic evidence meant it was equally valid to consider all six to be classified within the genus Platalea or alternatively the two placed in the monotypic genera Platibis and Ajaia, respectively. However, as the six species were so similar morphologically, keeping them within the one genus made more sense.


The roseate spoonbill (Platalea ajaja) is a gregarious wading bird of the ibis and spoonbill family, Threskiornithidae. It is a resident breeder in both South and North America. The roseate spoonbill's pink color is diet-derived, consisting of the carotenoid pigment canthaxanthin, like the American flamingo.

The roseate spoonbill is 71–86 cm (28–34 in) long, with a 120–133 cm (47–52 in) wingspan and a body mass of 1.2–1.8 kg (2.6–4.0 lb).[3] The tarsus measures 9.7–12.4 cm (3.8–4.9 in), the culmen measures 14.5–18 cm (5.7–7.1 in) and the wing measures 32.3–37.5 cm (12.7–14.8 in) and thus the legs, bill, neck and spatulate bill all appear elongated.[4] Adults have a bare greenish head ("golden buff" when breeding[5]) and a white neck, back and breast (with a tuft of pink feathers in the center when breeding), and are otherwise a deep pink. The bill is grey. There is no significant sexual dimorphism.

Like the American flamingo, their pink color is diet-derived, consisting of the carotenoid pigment canthaxanthin. Another carotenoid, astaxanthin, can also be found deposited in flight and body feathers. The colors can range from pale pink to bright magenta, depending on age, whether breeding or not, and location. Unlike herons, spoonbills fly with their necks outstretched. They alternate groups of stiff, shallow wingbeats with glides.


In the United States, the species is locally common in Texas, Florida, and southwest Louisiana. Generally, the species occurs in South America mostly east of the Andes, and in coastal regions of the Caribbean, Central America, Mexico, and the Gulf Coast of the United States, and from central Florida's Atlantic coast at Merritt Island National Wildlife Refuge, adjoined with NASA Kennedy Space Center at least as far north as South Carolina's Myrtle Beach.

Plume hunting in the eighteenth and nineteenth centuries almost drove the roseate spoonbill to extinction. However, following decades of conservation efforts, and the effects of climate change, the range of the roseate spoonbill has expanded considerably in the 21st century. For instance, the species was recorded breeding in the state of Georgia for the first time in 2011. Moreover, its presence in South Carolina has expanded significantly since the 1970s, as well as a single sighting of the bird in both Michigan and Wisconsin. The last known recorded log of the bird in the state of Wisconsin was of a deceased specimen in 1845 in Rock County. It made an historic reappearance 178 years later when a specimen was sighted by a crew that was doing birding surveys on the restricted-access Cat Island Causeway on July 27, 2023.

In the summer of 2021, sightings of the bird were reported well outside its typical range, including in Washington, D.C., upstate New York, and even New Hampshire. A large flock was spotted in Huntley Meadows Park in Fairfax County, Virginia, drawing a large crowd of spectators.

In Florida Bay, roseate spoonbills are an ecological and scientific indicator species. The number of nests varies with both the amount of fresh water and the depth of seawater there, as wetlands turn into open ocean. The birds are choosing to nest further north and inland in Florida, with sharp changes in nest locations noted in the years 2006–2020.
