25-3-2016 MONTE CORONA, VALENCIA - WHITE WAGTAIL (Motacilla alba)


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

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


White wagtails are usually seen alone or in pairs, but during migration, they often gather in flocks at good feeding areas or roost at night. These birds feed by day on the ground or on the wing. They may also forage in shallow water catching prey in the mud or may hover over water. The most conspicuous habit of White wagtails is a near-constant tail wagging, a trait that has given the birds their common name. The reasons for this behavior are poorly understood but it has been suggested that wagtails may flush prey, or signal submissiveness to other wagtails. The call of these birds is a sharp 'chisick' and their song consists of twittering phrases; the males use a series of contact calls to attract the female.

26-3-2016 GANDIA, VALENCIA - WESTERN CATTLE EGRET (MALE) (Bubulcus ibis)


The short, thick-necked Western Cattle Egret spends most of its time in fields rather than streams. It forages at the feet of grazing cattle, head bobbing with each step, or rides on their backs to pick at ticks. This stocky white heron has yellow plumes on its head and neck during breeding season. Originally from Africa, it found its way to North America in 1953 and quickly spread across the continent. Elsewhere in the world, it forages alongside camels, ostriches, rhinos, and tortoises—as well as farmers’ tractors.

25-3-2016 VILLALONGA RESERVOIR, WHITE WAGTAIL (Motacilla alba)


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

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


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

25-3-2016 VILLALONGA RESERVOIR, VALENCIA - EUROPEAN SERIN (Serinus serinus)


The European serin, or simply the serin (Serinus serinus ), is the smallest European species of the family of finches (Fringillidae) and is closely related to the Atlantic canary. Its diet consists mainly of a combination of buds and seeds.

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.

25-3-2016 VILLALONGA RESERVOIR, VALENCIA - EUROPEAN MOORHEN (Gallinula chloropus)


The common moorhen has a distinctive, slate-black breast, dark black head and neck, olive-green back, white rump, and a white stripe on each flank. This bird stands erect on large yellow legs and feet. Each leg has a red band above the upper joint just below the feathers. The feature that distinguishes it from other gallinules is the bright red shield on the face between the eyes. Size36 cm (14 in.) in length Weight200 to 340 g (7 to 12 oz.) DietThe species is omnivorous and opportunistic with a diet that consists of earthworms, crustaceans, mollusks, adult and larval insects (especially flies, mayflies, bugs, beetles, and butterflies), spiders, small fish, tadpoles, and occasionally birds eggs, algae, moss, aquatic plants, seeds, flowers, berries, and fruit. IncubationMales and females share the task of incubating the eggs. After about 3 weeks, the chicks hatch. The young are able to swim soon after they hatch, but interestingly enough they lose this skill as they mature. Clutch SizeCommon moorhens breed from April to August. The female lays a clutch of 6–10 eggs, and may lay 2–3 clutches in a season.

25-3-2016 VILLALONGA RESERVOIR, VALENCIA - LITTLE EGRET (Egretta garzetta)


The Little egret (Egretta garzetta) is small elegant heron in the family Ardeidae. As an aquatic bird, it feeds in shallow water and on land, consuming a variety of small creatures. At one time common in Western Europe, the Little heron was hunted extensively in the 19th century to provide plumes for the decoration of hats and became locally extinct in Northwestern Europe and scarce in the south. Around 1950, conservation laws were introduced in southern Europe to protect the species and their numbers began to increase.
The plumage of the Little egret is normally entirely white, although there are dark forms with largely bluish-grey plumage. In the breeding season, the adult has two long plumes on the nape that form a crest. These plumes are about 150 mm (6 in) and are pointed and very narrow. There are similar feathers on the breast, but the barbs are more widely spread. 


There are also several elongated scapular feathers that have long loose barbs and may be 200 mm (8 in) long. During the winter the plumage is similar but the scapulars are shorter and more normal in appearance. The bill is long and slender and it and the lores are black. There is an area of greenish-grey bare skin at the base of the lower mandible and around the eye which has a yellow iris. The legs are black and the feet yellow. Juveniles are similar to non-breeding adults but have greenish-black legs and duller yellow feet, and may have a certain proportion of greyish or brownish feathers. The subspecies nigripes differs in having yellow skin between the bill and eye, and blackish feet. During the height of courtship, the lores turn red and the feet of the yellow-footed races turn red.


The breeding range of the western race (E. g. garzetta) includes southern Europe, the Middle East, much of Africa and southern Asia. Northern European populations are migratory, mostly travelling to Africa although some remain in southern Europe, while some Asian populations migrate to the Philippines. The eastern race, (E. g. nigripes), is resident in Indonesia and New Guinea, while E. g. immaculata inhabits Australia and New Zealand, but does not breed in the latter. During the late twentieth century, the range of the little egret expanded northwards in Europe and into the New World, where a breeding population was established on Barbados in 1994. The birds have since spread elsewhere in the Caribbean region and on the Atlantic coast of the United States.

The little egret's habitat varies widely, and includes the shores of lakes, rivers, canals, ponds, lagoons, marshes and flooded land, the bird preferring open locations to dense cover. On the coast it inhabits mangrove areas, swamps, mudflats, sandy beaches and reefs. Rice fields are an important habitat in Italy, and coastal and mangrove areas are important in Africa. The bird often moves about among cattle or other hoofed mammals. 

25-3-2016 MONTE CORONA, VALENCIA - HOUSE SPARROW (FEMALE) (Passer domesticus)


These noisy and sociable birds are found around the world, thanks to their cheerful ability to make the most of humanity's rubbish and wastefulness. But monitoring suggests a severe decline in the UK House Sparrow population, recently estimated as dropping by 71% between 1977 and 2008 with large falls in both rural and urban populations. Their numbers are still dropping in England, Breeding Bird Survey data indicates recent population increases in Scotland, Wales and Northern Ireland.

House Sparrows are aggressive and may evict other species to take over their nest sites.

House Sparrows have lived alongside humans for centuries, taking advantage of spilt grain and food scraps.

They’re the most common bird seen during the Big Garden Birdwatch and if you put up feeders you’re almost certain to see them (they particularly love fat balls and sunflower hearts).

You might also spot them hopping about on city streets, in stations and parks, as well as out in the countryside in hedgerows and on agricultural fields. 

25-3-2016 MONTE CORONA, VALENCIA - SARDINIAN WARBLER (MALE) (Sylvia melanocephala)


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


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


This is a bird of open country and cultivation, with bushes for nesting. The nest is built in low shrub or brambles, and 3-6 eggs are laid. Like most "warblers", it is insectivorous, but will also take berries and other soft fruit.

26-3-2016 XATIVA, VALENCIA - EURASIAN SPARROWHAWK (Accipiter nisus)


The Eurasian sparrowhawk (Accipiter nisus), also known as the northern sparrowhawk or simply the sparrowhawk, is a small bird of prey in the family Accipitridae. Adult male Eurasian sparrowhawks have bluish grey upperparts and orange-barred underparts; females and juveniles are brown above with brown barring below. The female is up to 25% larger than the male – one of the greatest size differences between the sexes in any bird species. Though it is a predator which specialises in catching woodland birds, the Eurasian sparrowhawk can be found in any habitat and often hunts garden birds in towns and cities. Males tend to take smaller birds, including tits, finches, and sparrows; females catch primarily thrushes and starlings, but are capable of killing birds weighing 500 g (18 oz) or more.

The Eurasian sparrowhawk is found throughout the temperate and subtropical parts of the Old World; while birds from the northern parts of the range migrate south for winter, their southern counterparts remain resident or make dispersive movements. Eurasian sparrowhawks breed in suitable woodland of any type, with the nest, measuring up to 60 cm (24 in) across, built using twigs in a tree. Four or five pale blue, brown-spotted eggs are laid; the success of the breeding attempt is dependent on the female maintaining a high weight while the male brings her food. The chicks hatch after 33 days and fledge after 24 to 28 days.

The probability of a juvenile surviving its first year is 34%, with 69% of adults surviving from one year to the next. Mortality in young males is greater than that of young females and the typical lifespan is four years. This species is now one of the most common birds of prey in Europe, although the population crashed after the Second World War. Organochlorine insecticides used to treat seeds before sowing built up in the bird population, and the concentrations in Eurasian sparrowhawks were enough to kill some outright and incapacitate others; affected birds laid eggs with fragile shells which broke during incubation. However, its population recovered after the chemicals were banned, and it is now relatively common, classified as being of least concern by BirdLife International.

The Eurasian sparrowhawk's hunting behaviour has brought it into conflict with humans for hundreds of years, particularly racing pigeon owners and people rearing poultry and gamebirds. It has also been blamed for decreases in passerine populations. Studies of racing pigeon deaths found that Eurasian sparrowhawks were responsible for less than 1%. Falconers have utilised the Eurasian sparrowhawk since at least the 16th century; although the species has a reputation for being difficult to train, it is also praised for its courage. The species features in Teutonic mythology and is mentioned in works by writers including William Shakespeare, Alfred, Lord Tennyson and Ted Hughes.

23-3-2016 MARJAL DEL MORO, SAGUNTO - EUROPEAN GOLDFINCH (MALE) (Carduelis carduelis)


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


The European goldfinch or simply the goldfinch (Carduelis carduelis) is a small passerine bird in the finch family that is native to Europe, North Africa and western and central Asia. It has been introduced to other areas, including Australia, New Zealand and Uruguay.

The breeding male has a red face with black markings around the eyes, and a black-and-white head. The back and flanks are buff or chestnut brown. The black wings have a broad yellow bar. The tail is black and the rump is white. Males and females are very similar, but females have a slightly smaller red area on the face.

The goldfinch is often depicted in Italian Renaissance paintings of the Madonna and Child.

They attach their nests to tree twigs using spider silk.

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

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

23-3-2016 MARJAL DEL MORO, SAGUNTO - RED CRESTED POCHARD (MALE) (Netta rufina)


The red-crested pochard (Netta rufina ) is a large diving duck. The scientific name is derived from Greek Netta "duck", and Latin rufina, "golden-red" (from rufus, "ruddy"). Its breeding habitat is lowland marshes and lakes in southern Europe and it extends from the steppe and semi-desert areas on the Black Sea to Central Asia and Mongolia, wintering in the Indian Subcontinent and Africa. It is somewhat migratory, and northern birds winter further south into north Africa.

The adult male is unmistakable. It has a rounded orange head, red bill and black breast. The flanks are white, the back brown, and the tail black. The female is mainly a pale brown, with a darker back and crown and a whitish face. Eclipse males are like females but with red bills. They are gregarious birds, forming large flocks in winter, often mixed with other diving ducks, such as common pochards. They feed mainly by diving or dabbling. They eat aquatic plants, and typically upend for food more than most diving ducks.

23-3-2016 MARJAL DEL MORO, SAGUNTO - RED ADMIRAL BUTTERFLY (Vanessa atalanta)


Vanessa atalanta, the red admiral or, previously, the red admirable, is a well-characterized, medium-sized butterfly with black wings, red bands, and white spots. It has a wingspan of about 2 inches (5 cm). It was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. The red admiral is widely distributed across temperate regions of North Africa, the Americas, Europe, Asia, and the Caribbean. It resides in warmer areas, but migrates north in spring and sometimes again in autumn. Typically found in moist woodlands, the red admiral caterpillar's primary host plant is the stinging nettle (Urtica dioica); it can also be found on the false nettle (Boehmeria cylindrica). The adult butterfly drinks from flowering plants like Buddleia and overripe fruit. Red admirals are territorial; females will only mate with males that hold territory. Males with superior flight abilities are more likely to successfully court females. It is known as an unusually calm butterfly, often allowing observation at a very close distance before flying away, also landing on and using humans as perches.

23-3-2016 MARJAL DEL MORO, SAGUNTO - NORTHERN SHOVELER (MALE) (Spatula clypeata)


The Northern shoveler (Spatula clypeata) is a widespread species of duck unmistakable in the northern hemisphere due to its large spatulate bill. In Britain, it is known simply as the shoveler. One part of its scientific name Spatula is the Latin for a "spoon" or "spatula"; the other part is derived from the Latin clypeata and can be translated as "shield-bearing".

During the breeding season, the male of this species has an iridescent dark green head, white breast, and chestnut belly and flanks. In flight, pale blue forewing feathers are revealed, separated from the green speculum by a white border. In early fall the male will have a white crescent on each side of the face. In non-breeding (eclipse) plumage, the male resembles the female. The female is a drab mottled brown like other dabblers, with plumage much like a female mallard, but easily distinguished by the long broad bill, which is gray-tinged with orange on the cutting edge and lower mandible. The female's forewing is gray.


Northern shovelers breed in wide areas across Eurasia, western North America, and the Great Lakes region of the United States. They are strongly migratory and winter in southern Europe, Africa, the Indian Subcontinent, the Caribbean, northern South America, the Malay Archipelago, Japan, and other areas. In North America, they winter south of a line from Washington to Idaho, from New Mexico east to Kentucky, and along the Eastern Seaboard as far north as Massachusetts. Northern shovelers are birds of open wetlands, such as wet grassland or marshes with some emergent vegetation. Preferred feeding areas include lakes, estuaries, coastal shorelines, salt marshes, flooded fields, and agricultural ponds.

Northern shovelers are social ducks that live in small flocks and coexist peacefully with many other species. They feed during the day by dabbling for plant food, often by swinging their bill from side to side and using the bill to strain food from the water. Their wide-flat bill is equipped with well-developed lamellae; these are small, comb-like structures on the edge of the bill that act like sieves, allowing the birds to skim crustaceans and plankton from the water's surface. This adaptation gives them an advantage over other puddle ducks, with which they do not have to compete for food resources during most of the year. Thus, mud-bottomed marshes rich in invertebrate life are their habitat of choice. During the midday heat, the birds usually rest on land near the water. Northern shovelers are fairly quiet and communicate with each other only in certain situations; males have a low clunking call, whereas females have a light Mallard-like quack.

23-3-2016 MARJAL DEL MORO, SAGUNTO - MALLARD (FEMALE) (Anas platyrhynchos)


The mallard or wild duck (Anas platyrhynchos) is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa, and has been introduced to New Zealand, Australia, Peru, Brazil, Uruguay, Argentina, Chile, Colombia, the Falkland Islands, and South Africa. This duck belongs to the subfamily Anatinae of the waterfowl family Anatidae.  Mallards live in wetlands, eat water plants and small animals, and are social animals preferring to congregate in groups or flocks of varying sizes.

23-3-2016 MARJAL DEL MORO, SAGUNTO - GREATER FLAMINGO (Phoenicopterus roseus)


These famous pink birds can be found in warm, watery regions on many continents. They favor environments like estuaries and saline or alkaline lakes. Considering their appearance, flamingos are surprisingly fluid swimmers, but really thrive on the extensive mud flats where they breed and feed.

Greater flamingos are likely to be the only tall, pink bird in any given locale. They also have long, lean, curved necks and black-tipped bills with a distinctive downward bend.


Their bent bills allow them to feed on small organisms—plankton, tiny fish, fly larvae, and the like. In muddy flats or shallow water, they use their long legs and webbed feet to stir up the bottom. They then bury their bills, or even their entire heads, and suck up both mud and water to access the tasty morsels within. A flamingo's beak has a filterlike structure to remove food from the water before the liquid is expelled.

Shrimplike crustaceans are responsible for the flamingo's pink color. The birds pale in captivity unless their diet is supplemented.


Greater flamingos live and feed in groups called flocks or colonies. They find safety in numbers, which helps to protect individual birds from predators while their heads are down in the mud. Greater flamingos also breed while gathered in groups. Once mating is complete, a pair takes turns incubating their single egg. Young flamingos are born gray and white and do not turn pink for two years. In years when wetlands and pools are dry and food scarce, flamingoes may not breed.


The Greater Flamingo occurs in West Africa throughout the Mediterranean to the Southwest and South Asia, and throughout sub-Saharan Africa, Iran, Kazakhstan and the Middle East.

Greater flamingos are one of the world’s most iconic avian species and raising awareness of this unique species is important. Learn about greater flamingo habitat, diet, and breeding, and potential threats facing these beautiful birds.


Greater flamingos are the largest of the six flamingo species and the most widespread. Classified as “Least Concern” (LC) by the IUCN Red List of Threatened Species, they occur in Africa, the Indian subcontinent, the Middle East, and southern Europe. Despite this classification, like all common species, they have little protection from development encroaching on their habitat. Their populations are being monitored, and conservation sites have been identified should the species begin to decline. Programs are underway in Europe to raise public awareness, protect breeding and feeding wetlands, and warden against disturbance.


Standing 110 – 150cm (43in – 59 in) tall and weighing 2 – 4 kg (4.4 – 8.8 lb), they are often seen feeding among smaller lesser flamingos in their African range. They are much larger, with the greatest height for lesser flamingos being 90cm. Greater flamingo plumage is pale pink with whitish-yellow eyes, and the bill is narrow and pink, with a distinct black tip. In contrast, lesser flamingos have a very dark deep bill and red eyes. Both species have red legs and black flight feathers, which are largely hidden if the wings are folded, and the wings have deeper salmon coloured feathers that are most obvious in flight. Greater flamingos have a wingspan of 1.4 and 1.7 metres and fly with outstretched necks and legs extended behind. Chicks are born with grey plumage and take two to three years to develop adult plumage.


Like all flamingo species, the greater flamingo lives and feeds on highly alkaline soda lakes, coastal lagoons, and mudflats. Gathering in flocks that may vary from a dozen birds to thousands, the birds move in unison when threatened as this behaviour helps to protect them from predators, especially when their heads are submerged while feeding. Birds in cooler areas will migrate to warmer areas in winter. Threats to their survival include contamination of their habitat and water sources by bacteria and toxins from industrial runoff and disturbance of their nesting sites.

All flamingos are filter feeders, sucking water through their bills to trap algae, shrimp, small crustaceans, molluscs, and tiny fish. Wading in shallow water, greater flamingos use their feet to stir up the mud containing potential food. Their bill, containing thousands of rigid microscopic plates known as lamellae, is used upside down to filter the water stirred up by their feet. Their diet is rich in alpha and beta carotenoid pigments, which, when digested, are deposited into the skin and feathers resulting in pink colouration. Birds with deficient diets will lose their pink plumage, skin and beak colour, and birds feeding chicks will often be paler in colour.

23-3-2016 MARJAL DEL MORO, SAGUNTO - EURASIAN GREAT CORMORANT (Phalacrocorax carbo)


Great cormorants are monogamous, with pairs sometimes reuniting in subsequent years. The male chooses the nest site, displaying to attract the female by waving his wings up and down and flashing his white rump patch. He will also swing his head from side to side while holding his tail erect and calling loudly. The female responds by swinging her head slightly and “purring”. This species breeds at any time, depending on food resources. Breeding takes place in colonies of as many as 2,000 pairs, although colonies of a smaller size are typical. Colonies are often located close to other species, like darters, herons, and spoonbills. The parents build their nest with reeds, sticks, and seaweeds on a cliff, in a tree, or in a bush, according to the region. Often a nest is reused. 2 to 6 eggs are laid, with an average of 3-4. The parents share the incubation for 27 to 31 days. The altricial chicks hatch at intervals and fledge at about 50 days old. They remain with their parents for 50 or more days, relying on them for food. The young start to breed between 2 and 4 years old, typically when 3 years old.


Great cormorants have large populations and are widespread, although surveys are not complete across their range. Being an important fish competitor, in the past, they were almost extinct in Europe. However, in recent years increases have been observed, thanks to intensive protection. But in some countries, expanding conflicts with fish farms and fisheries lead to new persecution. Another threat is that hatchlings may be eaten by raptors before fledging.

The IUCN Red List reports that the global population of Great cormorants is about 1,400,000-2,100,000 individuals. The European population is estimated at 401,000-512,000 pairs, which equates to 803,000-1,020,000 mature individuals. Overall, currently, Great cormorants are classified as Least Concern (LC) on the IUCN Red List and their numbers today are increasing.

2-2-2015 JALON, ALICANTE - EUROPEAN ROBIN (Erithacus rubecula)


The European robin (Erithacus rubecula) is a small insectivorous passerine bird. The term robin is also applied to some birds in other families with red or orange breasts. These include the American robin (Turdus migratorius ), a thrush, and the Australasian robins of the family Petroicidae.

The male and female European robins are similar in coloration, with an orange breast and face lined with grey, brown upperparts, and a whitish belly. The bill and eyes are black. Juveniles are spotted brown and white in coloration, with patches of orange gradually appearing.


European robins occur in Eurasia east to Western Siberia, south to Algeria, and on the Atlantic islands as far west as the Central Group of the Azores and Madeira. Irish and British robins are largely resident but a small minority, usually female, migrate to southern Europe during winter, a few as far as Spain. Scandinavian and Russian robins migrate to Britain and western Europe to escape the harsher winters. European robins prefer spruce woods in northern Europe, contrasting with their preference for parks and gardens in Ireland and Great Britain. These may also be found in grasslands, shrubby vegetation, hedgerows with some tall trees, orchards, and farmlands.

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

20-3-2016 MONTE CORONA, VALENCIA - SARDINIAN WARBLER (MALE) (Sylvia melanocephala)


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


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

This is a bird of open country and cultivation, with bushes for nesting. The nest is built in low shrub or brambles, and 3-6 eggs are laid. Like most "warblers", it is insectivorous, but will also take berries and other soft fruit.

Male Sardinian warblers have a strongly contrasting plumage: a black head and upper face, white throat, light grey back and wings, and a paler greyish-white belly. Its tail is dark, edged with white, and it has brownish legs. The eye is reddish-brown, surrounded by a pinkish-orange eye ring.

20-3-2016 MONTE CORONA - 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 breed in much of Europe, western Asia, and northwestern Africa. They are partial migrants; birds from the colder areas of their range winter in northwestern Europe, around the Mediterranean, and in tropical Africa. Some German birds have adapted to spending the winter in gardens in Great Britain and Ireland. Eurasian blackcaps breed in mature deciduous woodlands, with good scrub cover below the trees, and may also be found in parks, large gardens, and overgrown hedges. The preferred winter habitat around the Mediterranean is scrub and olive orchards, while in Africa they occur in cultivated land, acacia scrub, mangroves, and forest.


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.

19-3-2016 GANDIA, 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).
