27-2-2016 GANDIA, VALENCIA - EURASIAN BLACKBIRD (MALE) (Turdus merula)

The Common blackbird (Turdus merula) is a species of true thrush. It is also called the Eurasian blackbird (especially in North America, to distinguish it from the unrelated New World blackbirds), or simply the blackbird where this does not lead to confusion with a similar-looking local species. This common and conspicuous species has given rise to a number of literary and cultural references, frequently related to its song.

The adult male has glossy black plumage, blackish-brown legs, a yellow eye ring, and an orange-yellow bill. The bill darkens somewhat in winter. The adult female is sooty-brown with a dull yellowish-brownish bill, a brownish-white throat, and some weak mottling on the breast. The juvenile is similar to the female but has pale spots on the upperparts, and the very young juvenile also has a speckled breast. Young birds vary in the shade of brown, with darker birds presumably males. The first-year male resembles the adult male but has a dark bill and weaker eye ring, and its folded wing is brown, rather than black like the body plumage.

25-2-2016 ALBUFERA, VALENCIA - COMMON CHIFFCHAFF (Phylloscopus collybita)

The Common chiffchaff (Phylloscopus collybita) is a widespread leaf warbler found throughout northern and temperate Europe and the Palearctic. It has a number of subspecies, some of which are now treated as full species. The female of this species is responsible for building a nest and assumes most of the responsibility for brooding and feeding the chicks, whilst the male has little involvement in nesting, but defends his territory against rivals, and attacks potential predators.

The Common chiffchaff is greenish-brown above and off-white below. It has dark legs, a fine dark bill, and a short primary projection (extension of the flight feathers beyond the folded wing). As the plumage wears, it gets duller and browner, and the yellow on the flanks tends to be lost. The newly fledged juvenile is browner above than the adult, with yellow-white underparts, but molts about 10 weeks after acquiring its first plumage. After molting, both the adult and the juvenile have brighter and greener upper parts and a paler supercilium (also known as an "eyebrow).

Common chiffchaffs breed across Europe and Asia, with isolated populations in northwest Africa, northern and western Turkey, and northwestern Iran. They are migratory birds that winter in southern and western Europe, southern Asia, and North Africa. Their breeding habitat includes open woodlands with some taller trees and ground cover for nesting purposes. In winter, Common chiffchaffs use a wider range of habitats including scrub, and willow thickets, and are often found near water. They also frequent parks, gardens, hedgerows, and cultivated areas.

Common chiffchaffs are active diurnal birds. They are generally solitary but may join small flocks including other warblers prior to migration. Chiffchaffs forage both on the ground and in bushes, low vegetation, and trees, moving restlessly through foliage or briefly hovering. They may even pick insects from the water surface. These small birds require about one-third of their weight in insects daily, and they feed almost continuously in the autumn to put on extra fat as fuel for the long migration flight. Common chiffchaffs are among the last songbirds to leave in late autumn and are one of the first to return to their breeding areas in the spring and their repetitive cheerful 'chiff-chaff' song is one of the first signs that spring has returned. Their common call is a soft and simple 'hooeet' or 'hweet' and mates communicate with each other using short 'drit' or 'it'.

25-2-2016 ALBUFERA, VALENCIA - BLACK HEADED GULL (JUVENILE) (Chroicocephalus ridibundus)

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

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

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

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

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

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

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

25-2-2016 ALBUFERA, VALENCIA - LITTLE EGRET (Egretta garzetta)

The little egret (Egretta garzetta) is a species of small heron in the family Ardeidae. It is a white bird with a slender black beak, long black legs and, in the western race, yellow feet. As an aquatic bird, it feeds in shallow water and on land, consuming a variety of small creatures. It breeds colonially, often with other species of water birds, making a platform nest of sticks in a tree, bush or reed bed. A clutch of three to five bluish-green eggs is laid and incubated by both parents for about three weeks. The young fledge at about six weeks of age.

Its breeding distribution is in wetlands in warm temperate to tropical parts of Europe, Africa, Asia, and Australia. A successful colonist, its range has gradually expanded north, with stable and self-sustaining populations now present in the United Kingdom.

The Little Egret is a small white heron with attractive white plumes on crest, back and chest, black legs and bill and yellow feet. It first appeared in the UK in significant numbers in 1989 and first bred in Dorset in 1996. Its arrival followed naturally from a range expansion into western and northern France in previous decades. It is now at home on numerous south coast sites, both as a breeding species and as a winter visitor.

With its yellow feet, which are used to flush prey when feeding in shallow water, the Little Egret is a distinctive member of the heron family.

Little Egrets first bred in Britain in 1996 and since then have successfully colonised much of southern Britain and Ireland. Most of the breeding colonies have been established within existing Grey Heron colonies, the two species nesting alongside one another.

The winter distribution is also currently restricted to the southern half of Britain & Ireland, despite the fact that young birds are known to move some distance from their natal site.

Little egrets are sociable birds and are often seen in small flocks. They are diurnal birds and feed mainly in the early morning and in the late afternoon. They use a variety of methods to procure their food; they stalk their prey in shallow water, often running with raised wings or shuffling their feet to disturb small fish, or may stand still and wait to ambush prey. Little egrets also make use of opportunities provided by cormorants disturbing fish or humans attracting fish by throwing bread into the water. On land, they walk or run while chasing their prey, feed on creatures disturbed by grazing livestock and ticks on the livestock, and even scavenge occasionally. Little egrets are silent birds in general, however, at their breeding colonies, they make various croaking and bubbling calls. When disturbed, they produce a harsh alarm call.

25-2-2016 ALBUFERA, VALENCIA - GREY HERON (Ardea cinerea)

The Grey heron (Ardea cinerea) is a large long-legged wading bird of the heron native to Europe and Asia and also parts of Africa. It lives in wetland areas and feeds on various aquatic creatures which it catches after standing stationary beside or in the water.

The plumage of the Grey heron is largely ashy-grey above, and greyish-white below with some black on the flanks. Adults have a head and neck white with a broad black supercilium that terminates in the slender, dangling crest, and bluish-black streaks on the front of the neck. The scapular feathers are elongated and the feathers at the base of the neck are also somewhat elongated. Immature birds lack the dark stripe on the head and are generally duller in appearance than adults, with a grey head and neck, and a small, dark grey crest. The pinkish-yellow beak is long, straight, and powerful, and is brighter in color in breeding adults. The iris is yellow and the legs are brown and very long.

Grey herons occur in most parts of Europe, Asia, and Africa. Over much of their range, these birds are resident, but populations from the more northerly parts of Europe migrate southwards; some remain in Central and Southern Europe, and others travel on to Africa south of the Sahara Desert. Grey herons can be found anywhere with suitable watery habitats that can supply their food. Although most common in the lowlands, they also occur in mountain tarns, lakes, reservoirs, large and small rivers, marshes, ponds, ditches, flooded areas, coastal lagoons, estuaries, and seashore. They sometimes forage away from water in the pasture, and can even be found in desert areas, hunting for beetles and lizards.

25-2-2016 ALBUFERA, VALENCIA - EURASIAN GREAT CORMORANT (Phalacrocorax carbo)

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

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

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

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

25-2-2016 ALBUFERA, VALENCIA - EURASIAN KESTREL (Falco tinnunculus)

The Common kestrel (Falco tinnunculus) is a bird of prey species that belongs to the falcon family Falconidae. This species occurs over a large range and in Britain, where no other kestrel species commonly occurs, it is generally just called "kestrel".

Common kestrels are small compared with other raptors, but larger than most songbirds. They are mainly light chestnut brown in color with blackish spots on the upperside and buff with narrow blackish streaks on the underside; the remiges are also blackish. The males have fewer black spots and streaks and their cap and tail are blue-grey. The tail is brown with black bars in females and has a black tip with a narrow white rim in both sexes. All Common kestrels have a prominent black malar stripe like their closest relatives. The cere, feet, and a narrow ring around the eye are bright yellow; the toenails, bill, and iris are dark. Juveniles look like adult females, but the underside streaks are wider; the yellow of their bare parts is paler.

Common kestrels are found in Europe, Asia, and Africa. These birds are sedentary but in the cold parts of their range, they migrate south in winter. Common kestrels live in open habitats such as tundra, taiga, grassland, shrubland, marshland, fields, and heaths. They can also be found in forested areas and readily adapt to human settlement, as long as sufficient swathes of vegetation are available. They also occur in wetlands, moorlands, arid savanna, and from the sea to the lower mountain range.

Common kestrels are usually seen alone but sometimes may travel in small flocks and nest in loose colonies. These birds hunt by day hovering about 10-20 m (35-65 ft) above the ground, searching for prey, either by flying into the wind or by soaring using ridge lift. Like most birds of prey, Common kestrels have keen eyesight enabling them to spot small prey from a distance. Once prey is sighted, the bird makes a short, steep dive toward the target. They often hunt along the sides of roads and motorways. Another favorite (but less conspicuous) hunting technique is to perch a bit above the ground cover, surveying the area. When the bird spots prey animals moving by, it will pounce on them. They also prowl a patch of hunting ground in a ground-hugging flight, ambushing prey as they happen across it. Common kestrels communicate with each other using various calls. When alarmed they utter 'kii-kii-kiikii' and in flight, the birds produce a 'kik-kik' call.

Common kestrels are monogamous and form long-lasting pair bonds. They start breeding in April or May in temperate Eurasia and between August and December in the tropics and southern Africa. Common kestrels nest in cavities, preferring holes in cliffs, trees, or buildings; in built-up areas, the birds will often nest on buildings and will reuse the old nests of other birds. Common kestrels are usually solitary nesters but may sometimes nest in loose colonies. The female lays a clutch of 3 to 7 eggs. Incubation lasts around 4 weeks, and only the female incubates the eggs. The male is responsible for providing her with food, and for some time after hatching this remains the same. Later, both parents share brooding and hunting duties until the young fledge, after 4-5 weeks. The family stays close together for a few weeks, during which time the young learn how to fend for themselves and hunt prey. They become reproductively mature and are ready to breed for the first time by the next breeding season.

The Cattle egret (Bubulcus ibis) is a cosmopolitan species of heron named for its association with cattle. It is the only member of the monotypic genus Bubulcus, although some authorities regard its two subspecies as full species, the Western cattle egret and the Eastern cattle egret. Despite the similarities in plumage to the egrets of the genus Egretta, it is more closely related to the herons of Ardea.

The Cattle egret is a stocky bird. It has a relatively short, thick neck, a sturdy bill, and a hunched posture. The nonbreeding adult has mainly white plumage, a yellow bill, and greyish-yellow legs. During the breeding season, adults of the nominate western subspecies develop orange-buff plumes on the back, breast, and crown, and the bill, legs, and irises become bright red for a brief period prior to pairing. The sexes are similar, but the male is marginally larger and has slightly longer breeding plumes than the female; juvenile birds lack coloured plumes and have a black bill.
