21-6-2017 RACO DE OLLA, VALENCIA - PIED AVOCET (Recurvirostra avosetta)
%2020.jpg)
The pied avocet, Recurvirostra avosetta, presents a striking silhouette with its bold black and white plumage. This large wader, belonging to the avocet and stilt family, Recurvirostridae, is adorned with a distinctive black cap and black markings on its wings and back, contrasting sharply against its otherwise white body. The species is noted for its elegant, upturned bill and elongated, bluish legs, which add to its graceful demeanor.
Adult pied avocets measure approximately 16.5–17.75 inches in length, with a wingspan stretching around 30–31.5 inches. Their long legs and upturned bills, measuring about 2.95–3.35 inches and 3–4 inches respectively, are key features for identification. Both sexes appear similar, while juveniles can be distinguished by their more greyish and sepia tones.
These birds favor shallow lakes with brackish water and exposed mudflats, which provide ideal foraging and breeding grounds.
The pied avocet breeds across temperate Europe and extends across the Palearctic to Central Asia and the Russian Far East. It is a migratory species, with most individuals wintering in Africa or southern Asia. Some, however, remain in the milder parts of their range during winter, such as southern Spain and southern England.

19-6-2017 VILLALONGA RESERVOIR, VALENCIA - EURASIAN REED WARBLER (Acrocephalus scirpaceus)
%2020.jpg)
The Common Reed Warbler, Acrocephalus scirpaceus, is a medium-sized warbler measuring approximately 13 cm in length with a wingspan ranging from 17 to 21 cm. It exhibits an unstreaked brown back with buff underparts. Both sexes are identical in appearance, which is typical for warblers. Juveniles can be distinguished by their richer buff underparts. The species is characterized by a flattened forehead and a robust, pointed bill.
When identifying the Common Reed Warbler, look for its brown, unstreaked back and buff underparts. The bird's supercilium is less pronounced than that of the larger Great Reed Warbler. In flight, observe the wing-span and listen for its distinctive song.
This species is almost exclusively found in reed beds, often with interspersed bushes, providing it with the necessary cover and nesting sites.
The Common Reed Warbler breeds across Europe into the temperate western Palaearctic and is migratory, wintering in sub-Saharan Africa. It is also a resident species in large parts of Africa.
19-6-2017 VILLALONGA RESERVOIR, VALENCIA - SPECKLED WOOD BUTTERFLY (Pararge aegeria)
The average wingspan of both males and females is 5.1 cm (2 in), although males tend to be slightly smaller than females. Furthermore, males possess a row of grayish-brown scent scales on their forewings that is absent in the females. Females have brighter and more distinct markings than males. The subspecies P. a. tircis is brown with pale yellow or cream spots and darker upperwing eyespots. The subspecies P. a. aegeria has a more orange background and the hindwing underside eyespots are reddish brown rather than black or dark gray. The two forms gradually intergrade into each other. Subspecies P. a. oblita is a darker brown, often approaching black with white rather than cream spots. The underside of its hindwings has a marginal pale purple band and a row of conspicuous white spots. The spots of subspecies P. a. insula are a tawny orange rather than a cream color. The underside of the forewings has patches of pale orange, and the underside of the hindwing has a purple-tinged band. Although there is considerable variation with each subspecies, identification of the different subspecies is manageable.
The morphology of this butterfly varies as a gradient down its geographic cline from north to south. The northern butterflies in this species have a bigger size, adult body mass, and wing area. These measurements decrease as one moves in a southerly direction in the speckled wood's range. Forewing length on the other hand increases moving in a northerly direction. This is due to the fact that in the cooler temperatures of the northern part of this butterfly's range, the butterflies need larger forewings for thermoregulation. Finally, the northern butterflies are darker than their southern counterpart, and there is a coloration gradient, down their geographical cline.
19-6-2017 VILLALONGA RESERVOIR, VALENCIA - WHITE LEGGED DAMSELFLY (Platycnemis pennipes)
The white-legged damselfly or blue featherleg (Platycnemis pennipes) is a damselfly of slow-flowing, muddy waters. It occurs from the Atlantic to Siberia and is often abundant throughout its range.
Platycnemis pennipes is about 32 millimetres (1.3 in) long. Mature adults differ from most other blue damselflies in having expanded white edges to the tibiae, paired black markings down most of the abdomen, broad pale brown double antehumeral stripes, wider head and a pale brown pterostigmata.
The male has a blue abdomen that is often pale and usually has a greenish thorax. The female is a very pale yellow-green colour with black markings.
This species favours unshaded slow-flowing sections of muddy rivers with abundant floating vegetation. it has been recorded in tidal rivers and the larvae seem well able to tolerate brackish water. It also occurs in muddy streams but is rare in lakes or ponds of any sort. In north-west Europe, it is mostly confined to flowing waters.
Mating is preceded by the male displaying his white legs in a fluttering display flight in front of females. Elongated eggs are laid whilst in tandem, into emergent stems and especially the underside of floating leaves. The larvae live amongst bottom debris and emerge after two years.
After emerging, adults tend to congregate in the shelter of tall vegetation, although some immatures wander away from water and have been found five kilometres away from the nearest breeding site.
19-6-2017 MONTE CORONA, VALENCIA - SIERRA NEVADA OCELLATED LIZARD (Timon nevadensis)
%2020.jpg)
The Ocellated lizard (Timon lepidus) is a member of the family Lacertidae (wall lizards). It is one of the largest members of its family. The species is can be found only in southwestern Europe.
The Ocellated lizard is a robust reptile with a serrated collar. The male has a characteristic broad head. It has thick, strong legs, with long, curved claws. The dorsal background color is usually green, but sometimes grey or brownish, especially on the head and tail. This is overlaid with black stippling that may form a bold pattern of interconnected rosettes. The underside is yellowish or greenish with both the male and female sporting bright blue spots along the flanks, though the male is typically brighter in color than the female. Young are green, grey, or brown, with yellowish or white, often black-edged, spots all over.
Ocellated lizards are found throughout the Iberian peninsula (Spain, Portugal, Gibraltar), and are patchily distributed in southern France and extreme northwestern Italy. These lizards live in various wild and cultivated habitats. They are rare at higher altitudes. They prefer dry, bushy areas, such as open woodland and scrub, old olive groves, and vineyards, and are sometimes found in more open, rocky, or sandy areas.

They prefer dry, bushy areas, such as open woodland and scrub, old olive groves, and vineyards, and are sometimes found in more open, rocky, or sandy areas.
Ocellated lizards are territorial solitary reptiles that meet only for mating. They are diurnal in their habits but during hot summer days may switch to nocturnal activity. Ocellated lizards usually stay on the ground, but climb well on rocks and in trees. They can dig holes and sometimes use abandoned rabbit burrows. They also often bask on roadsides. During the coldest month of the year, Ocellated lizards retreat underground for hibernation.
Ocellated lizards are carnivores. They mainly eat large insects, especially beetles, and snails, and also rob birds’ nests and occasionally take reptiles, frogs, and small mammals. They may also eat fruit and other plant matter, especially in dry areas.
Ocellated lizards breed in late spring or early summer. Males are territorial in spring and fight in the breeding season. The female lays up to 22 eggs in June and July about 3 months after mating, hiding them under stones and logs or in leaf litter, or in loose damp soil. It tends to lay fewer, larger eggs in dry areas. The eggs hatch in 8 to 14 weeks and the young become reproductively mature at 2 years of age.

18-6-2017 VILLALONGA RESERVOIR, VALENCIA - HOUSE SPARROW (MALE) (Passer domesticus)
%20(Passer%20domesticus)%2020.jpg)
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.
%20(Passer%20domesticus)%2021.jpg)
Because of its numbers, ubiquity, and association with human settlements, the house sparrow is culturally prominent. It is extensively, and usually unsuccessfully, persecuted as an agricultural pest. It has also often been kept as a pet, as well as being a food item and a symbol of lust, sexual potency, commonness, and vulgarity. Though it is widespread and abundant, its numbers have declined in some areas. The animal's conservation status is listed as least concern on the IUCN Red List.
18-6-2017 VILLALONGA RESERVOIR, VALENCIA - EUROPEAN SERIN (MALE) (Serinus serinus)
%20(Serinus%20serinus)%2020.jpg)
The European serin is a small short-tailed bird, 11–12 cm in length. The upper parts are dark-streaked greyish green, with a yellow rump. The yellow breast and white belly are also heavily streaked. The male has a brighter yellow face and breast, yellow wing bars and yellow tail sides. The song of this bird is a buzzing trill, very familiar in Mediterranean countries.
It breeds across southern and central Europe and North Africa. Southern and Atlantic coast populations are largely resident, but the northern breeders migrate further south in Europe for the winter. Open woodland and cultivation, often with some conifers, is favoured for breeding. It builds its nest in a shrub or tree, laying 3–5 eggs. It forms flocks outside the breeding season, sometimes mixed with other finches.
The food is mainly seeds, and, in the breeding season, insects. This small serin is an active and often conspicuous bird.

16-6-2017 PETROLA, ALBACETE - CORN BUNTING (Emberiza calandra)
The corn bunting (Emberiza calandra ) is a passerine bird in the bunting family Emberizidae, a group now separated by most modern authors from the finches, Fringillidae. This is a large bunting with heavily streaked buff-brown plumage. The sexes are similar but the male is slightly larger than the female. Its range extends from Western Europe and North Africa across to northwestern China.
This is an unusual bunting because the plumages of the sexes are similar in appearance, though the male is approximately 20% larger than the female. This large bulky bunting is 16–19 cm long, with a conspicuously dark eye and yellowish mandibles. Males lack any showy colours, especially on the head, which is otherwise typical of genus Emberiza. Both sexes look something like larks, being streaked grey-brown above with whitish underparts. The underparts are streaked over the flanks and breast, and the streaking forms gorget around the throat. The lesser wing coverts are distinctively dark and white-tipped. The tail is plain brown.
The song of the male is a repetitive metallic sound, usually likened to jangling keys, which is given from a low bush, fence post or telephone wires.
15-6-2017 MONTE CORONA, VALENCIA - LARGE PSAMMODROMUS LIZARD (Psammodromus algirus)
%2020.jpg)
Psammodromus algirus, known commonly as the Algerian psammodromus or the large psammodromus, is a species of lizard in the family Lacertidae. The species is found in southwestern Europe and northwestern Africa.
Subspecies
There are four subspecies:
Psammodromus algirus algirus (Linnaeus, 1758)
Psammodromus algirus doriae Bedriaga, 1886
Psammodromus algirus nollii Fischer, 1887
Psammodromus algirus ketamensis Galán, 1931
%2021.jpg)
Psammodromus algirus is found in North Africa (Morocco, Algeria, and Tunisia) and in Southwestern Europe (Iberian Peninsula: Portugal, Spain, Andorra, Gibraltar; southernmost France, and Italy near Lampedusa).
The IUCN assessment from 2009 treats Psammodromus algirus nollii and Psammodromus algirus ketamensis as full species and restricts Psammodromus algirus to North Africa.
P. algirus typically occurs in dense bushy vegetation, but it can also venture to more open areas. It can be found at at elevations up to 2,600 m (8,500 ft) above sea level, but it is more common at lower elevations.
Psammodromus algirus mainly feeds on terrestrial arthropods, specifically Orthoptera, Formicidae, Coleoptera, Hemiptera, and Araneae.
P. algirus is threatened by habitat loss.
P. algirus commonly reaches a snout–vent length of about 7.5 cm (3.0 in), occasionally 9 cm (3.5 in). The tail is 2–3 times the body length. Dorsal colouration is usually metallic brownish with a pair of conspicuous white or yellowish stripes on both sides.
16-6-2017 LAGUNA DE HOYA ROSA, ALBACETE - WHITE HEADED DUCK (Oxyura leucocephala)
%2032.jpg)
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.
%2031.jpg)
The White-headed Duck favors lakes with open water and dense vegetation along the margins, which provide essential cover and nesting sites. These habitats include natural lakes and ponds as well as man-made water bodies.
This species has a breeding range that spans from Spain and North Africa to western and central Asia. Sightings have been reported north of their typical range, though the status of these observations is often uncertain due to the potential for escapees from captivity.
The White-headed Duck is an adept diver and swimmer, often opting to escape threats by swimming rather than taking flight. It exhibits a preference for aquatic environments where it can forage and seek refuge.
%2030.jpg)
An omnivorous diet characterizes this species, with a strong inclination towards vegetable matter. They forage by diving and swimming underwater, and display a notable reluctance to fly.
The International Union for Conservation of Nature (IUCN) has classified the White-headed Duck as "Endangered." Populations have seen a significant decline over the past decade, primarily due to habitat loss and hunting. Additionally, the Spanish population faces genetic dilution from interbreeding with the introduced Ruddy Duck (Oxyura jamaicensis), prompting conservation efforts to eradicate the non-native species from western Europe. The species is also protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA).
16-6-2017 PETROLA, ALBACETE - GREATER FLAMINGO (Phoenicopterus roseus)
The Greater flamingo (Phoenicopterus roseus) is the most widespread and largest species of the flamingo family. It was described by Peter Simon Pallas in 1811. The Greater flamingo was previously thought to be the same species as the American flamingo, but because of coloring differences of its head, neck, body, and bill, the two flamingos are now most commonly considered separate species.
Greater flamingos have an attractive coloration and appearance. Their feathers are pinkish/white, the wing coverts are red and the primary and secondary flight feathers are black. They have long pink bills with a black tip, yellow eyes and long pink legs. The male is bigger than the female, and juveniles have a gray-brown coloration, with some pink on their underparts, tail and wings, with the legs and beak being mainly brown.
The Greater flamingo inhabits Africa, the Middle East, southern Europe, and the Indian subcontinent. They occur in relatively shallow water bodies, such as saline lagoons, salt pans, large alkaline or saline lakes, and estuaries. Breeding takes place on sandbanks, mudflats, sandy or rocky islands, or open beaches.
Greater flamingos are very social. They travel in groups numbering up to thousands and they communicate by using visual and auditory cues. Greater flamingos are partially dispersive and migratory. They are traveling constantly, seeking areas with enough resources to sustain the whole flock, especially during the mating season. Greater flamingos keep their chicks together in crèches. Adults supervising crèches tend to act in a hostile way toward hatchlings if their own young are not in that crèche. Greater flamingos are diurnal, feeding during the day. Being bottom feeders, they rely on water levels that are low, and they move to new areas to find appropriate feeding conditions. They often bathe in fresh shallow water and preen their feathers to remove salt from them. They are not territorial birds but during breeding season they do defend their nests.

The Greater flamingo was previously thought to be the same species as the American flamingo, but because of coloring differences of its head, neck, body, and bill, the two flamingos are now most commonly considered separate species.
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.
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.
16-6-2017 CORAL RUBIO, ALBACETE - WHITE HEADED DUCK (Oxyura leucocephala)
%2020.jpg)
The white-headed duck (Oxyura leucocephala ) is a small diving duck some 45 cm (18 in) long. The male has a white head with black crown, a blue bill, and reddish-grey plumage. The female has a dark bill and rather duller colouring. Its breeding habitat is lakes with open water and dense vegetation at the margin. It dives under water and feeds on aquatic vegetation as well as some animal matter. It is more likely to swim away from a perceived threat than to fly. This duck is known from Spain, North Africa, Western Asia and Central Asia. Populations are declining, mostly due to loss of habitat and pollution, and the International Union for Conservation of Nature has rated the bird's status as "endangered".
%2021.jpg)
Adult males have a grey and reddish body, a blue bill and a largely white head with a black cap and neck. Adult females have a grey-brown body with a white face and a darker bill, cap, and cheek stripe. Length is 43–48 cm (17–19 in) and weight is 580–750 g (1.28–1.65 lb).
This duck breeds in Spain and North Africa, with a larger population in western and central Asia. Their breeding habitat is large tracts of open water, such as lakes and ponds including artificial water bodies, with dense stands of aquatic plants to provide shelter and nesting sites. Individuals are fairly frequently reported well north of their breeding range, but as with many wildfowl, the status of these extralimital records is clouded by the possibility of escapes from collections.
%2022.jpg)
These birds dive and swim under water. They are omnivorous, with vegetable matter predominating. They are reluctant to fly, preferring to swim for cover.
This duck is considered endangered due to a large reduction in populations in the last 10 years. Most of this decline is due to habitat loss and hunting, but interbreeding of the Spanish population with the introduced ruddy duck (Oxyura jamaicensis ) is a more recent threat. This has led to the attempted eradication of the American species from western Europe.
The white-headed duck is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies, and the International Union for Conservation of Nature has rated the bird's conservation status as being "endangered".

16-6-2017 CORAL RUBIO, ALBACETE - NORTHERN LAPWING (Vanellus vanellus)
Northern lapwings are found throughout temperate Eurasia. They are highly migratory over most of their extensive range, wintering further south as far as North Africa, northern India, Nepal, Bhutan, and parts of China. However, lowland breeders in the westernmost areas of Europe are residents. Northern lapwings inhabit wet grasslands, meadows, swampy heaths, bogs, marshes, other wetlands, and cultivated areas.
Outside of the breeding season, Northern lapwings are very gregarious birds. They feed in mixed flocks with Golden plovers and Black-headed gulls and often migrate in large flocks. In winter, these birds like to form huge flocks on open land, particularly arable land, and mud flats. Northern plovers prefer to feed at night when there is moonlight. They are very vocal birds in the breeding season, constantly calling during the crazed tumbling display flight performed by the male. The typical contact call of these birds is a loud, shrill ‘pee-wit’ from which they get their other name of peewit. Displaying males usually make a wheezy ‘pee-wit, wit wit, eeze wit’ during their display flight; these birds also make squeaking or mewing sounds.
16-6-2017 CORAL RUBIO, ALBACETE - PIED AVOCET (Recurvirostra avosetta)
%2020.jpg)
The pied avocet, Recurvirostra avosetta, presents a striking silhouette with its bold black and white plumage. This large wader, belonging to the avocet and stilt family, Recurvirostridae, is adorned with a distinctive black cap and black markings on its wings and back, contrasting sharply against its otherwise white body. The species is noted for its elegant, upturned bill and elongated, bluish legs, which add to its graceful demeanor.
Adult pied avocets measure approximately 16.5–17.75 inches in length, with a wingspan stretching around 30–31.5 inches. Their long legs and upturned bills, measuring about 2.95–3.35 inches and 3–4 inches respectively, are key features for identification. Both sexes appear similar, while juveniles can be distinguished by their more greyish and sepia tones.
These birds favor shallow lakes with brackish water and exposed mudflats, which provide ideal foraging and breeding grounds.
The pied avocet breeds across temperate Europe and extends across the Palearctic to Central Asia and the Russian Far East. It is a migratory species, with most individuals wintering in Africa or southern Asia. Some, however, remain in the milder parts of their range during winter, such as southern Spain and southern England.
