14-8-2016 VILLALONGA RESERVOIR, VALENCIA - BLACK HEADED GULL (JUVENILE) (Chroicocephalus ridibundus)

The Black-headed gull (Chroicocephalus ridibundus) is a small and one of the most abundant gulls in much of Europe and Asia, and also in eastern Canada. It displays a variety of compelling behaviors and adaptations. Some of these include removing eggshells from one's nest after hatching, begging co-ordination between siblings, differences between sexes, conspecific brood parasitism, and extra-pair paternity.

The summer adult has a chocolate-brown head (not black, although does look black from a distance), a pale grey body, black tips to the primary wing feathers, and a 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 and a black band on the tail. There is no difference in plumage between the sexes. In flight, the white leading edge to the wing is a good field mark. First-year birds have a black terminal tail band, more dark areas in the wings, and, in summer, a less fully developed dark hood.

Black-headed gulls breed in much of Europe, Asia, and in coastal eastern Canada. Most of their populations are migratory and winter further south, but some birds reside in the milder westernmost areas of Europe. Some Black-headed gulls also spend the winter in northeastern North America. They breed in large reed beds or marshes, or on islands in lakes, rivers, lagoons, deltas, and estuaries. They may also occur in ponds, canals, and flood lands, nesting on the heather moors, sand dunes, or beaches. During the winter these birds are found in estuaries with sandy or muddy beaches, ploughed fields, moist grasslands, reservoirs, urban parks, farmland, and gardens.

Black-headed gulls are highly gregarious birds, both when feeding or in evening roosts; they also breed in colonies. They are rarely seen at sea far from coasts. Black-headed gulls are active during the day and feed mainly by taking prey from the surface while swimming, or by dipping the head under the surface. They also walk along the coasts and probe for aquatic prey or catch flying insects on the wings. Black-headed birds are noisy, especially in colonies, with a familiar "kree-ar" call. When feeding they utter a sharp “kek-kek”.

Black-headed gulls are monogamous breeders. This means that males will mate with only one female and females will mate with only one male. The breeding season usually starts in late March; during this time pairs become very territorial and defend their nests vigorously. Black-headed gulls nest in big colonies and build their nests on the ground in low vegetation close to each other. Females lay 1 to 3 eggs and both parents incubate them within 22-26 days. The chicks are precocial; they are hatched with eyes open and are covered in down. They are able to stand within a day, but usually stay in the nest for a week and are fed by both parents. The chicks fledge about 35 days after hatching and become reproductively mature when they are 2 years old.

14-8-2016 VILLALONGA RESERVOIR, VALENCIA - GREEN SANDPIPER (Tringa ochropus)

The green sandpiper (Tringa ochropus) is a small wader (shorebird) of the Old World.

This species is a somewhat plump wader with a dark greenish-brown back and wings, greyish head and breast and otherwise white underparts. The back is spotted white to varying extents, being maximal in the breeding adult, and less in winter and young birds. The legs and short bill are both dark green.

It is conspicuous and characteristically patterned in flight, with the wings dark above and below and a brilliant white rump. The latter feature reliably distinguishes it from the slightly smaller but otherwise very similar solitary sandpiper (T. solitaria) of North America.

In flight it has a characteristic three-note whistle.

14-8-2016 ADOR CAMPO, VALENCIA - WOODCHAT SHRIKE (Lanius senator)

The woodchat shrike (Lanius senator ) is a member of the shrike family Laniidae. It can be identified by its red-brown crown and nape. It is mainly insectivorous and favours open wooded areas with scattered trees such as orchards, particularly when there is bare or sandy ground. The woodchat shrike breeds in southern Europe, the Middle East and northwest Africa, and winters in tropical Africa.

The woodchat shrike is 17–19 cm (6.7–7.5 in) in overall length which is slightly larger than a red-backed shrike. The male is a striking bird with black and white upper parts, a chestnut crown and pure white underparts. The race L. s. badius of the western Mediterranean lacks the large white wing patches. In the female and young birds, the upperparts are brown and white and vermiculated. Underparts are buff and also vermiculated.

The breeding range of the woodchat shrike is in southern Europe, northern Africa and the Middle East. The range extends from Portugal to Greece, Turkey, Iraq and Iran, and in the Arabian Peninsula including Bahrain and Kuwait, and from Mauritania and Western Sahara in northern Africa to Libya. This bird overwinters in tropical central Africa, its winter range extending from Senegal to Sudan and Ethiopia in the east and southwards to Gabon. This species often overshoots its breeding range on spring migration, and is a rare, but annual, visitor to Great Britain. The Balearic race badius has occurred in Britain around four times as a vagrant, and has also been recorded once in Ireland.

The woodchat shrike mainly eats insects, particularly beetles, but its diet can include other invertebrates and very occasionally small mammals and small birds. It hunts by perching on an exposed lookout such as on a branch of a tree or on a fence, typically 2–6 m (7–20 ft) above the ground, and then dropping or gliding down to its prey. It also makes sallying flights after flying insects. Small insects are crushed in its bill but large insects are dismembered. Impaling prey on a thorn has been recorded but is unusual. Indigestible material such as chitin, bones and hair is regurgitated as pellets.

Eggs are laid from early May to mid-July. The nest is built by both sexes and is placed in a tree, usually a fruit or olive tree. The nest is a strong cup of plant material which is lined with wool, hair, fine roots, cobwebs and lichen. The nest sometimes includes green plant material. The clutch is usually 5–6 eggs which are laid daily. The eggs are glossy and vary in colour: they can be pale olive-green, sandy, greyish-yellow or brown. They have brown to pale olive speckles concentrated at the broader end. For the nominate subspecies the average size is 23 mm × 17 mm (0.91 in × 0.67 in) with a calculated weight of 3.4 g (0.12 oz). After the last egg is laid they are incubated by the female; only very rarely does the male participate. The eggs hatch after 14–15 days. The young are cared for by both parents and fledge after 15–20 days. The parents continue to feed the fledgelings up to 3 to 4 weeks of age.

The longest lived woodchat shrike recorded by ring-recovery data is 5 years and eight months for a bird found dead in Germany.

The Spotted flycatcher (Muscicapa striata) is a small passerine bird found in most of Europe, Africa, and Asia. This species was described by the German naturalist Peter Simon Pallas in 1764 and has five recognized subspecies. It is declining in parts of its range.

14-8-2016 ADOR CAMPO, VALENCIA - BARN SWALLOW (Hirundo rustica)

The barn swallow (Hirundo rustica) is the most widespread species of swallow in the world, occurring on all continents, with vagrants reported even in Antarctica. It appears to have the largest natural distribution of any of the world's passerines, ranging over 251 million square kilometres globally.[not verified in body] It is a distinctive passerine bird with blue upperparts and a long, deeply forked tail. In Anglophone Europe, it is just called the swallow; in northern Europe, it is the only member of family Hirundinidae called a "swallow" rather than a "martin".

The barn swallow is a bird of open country that normally nests in man-made structures and consequently has spread with human expansion. It builds a cup nest from mud pellets in barns or similar structures and feeds on insects caught in flight. This species lives in close association with humans, and its insect-eating habits mean that it is tolerated by humans; this acceptance was reinforced in the past by superstitions regarding the bird and its nest. There are frequent cultural references to the barn swallow in literary and religious works due to both its living in close proximity to humans and its annual migration. The barn swallow is the national bird of Austria and Estonia. 

19-3-2015 SINGAPORE - RADJAH SHELDUCK (Tadorna radjah)

The radjah shelduck (Radjah radjah), is a species of shelduck found mostly in New Guinea and Australia, and also on some of the Moluccas. It is known alternatively as the raja shelduck, black-backed shelduck, or in Australia as the Burdekin duck.

The specific name radjah is from the Moluccan name Radja for the radjah shelduck on the island of Buru in Indonesia.

Formerly placed in the genus Tadorna, it differs markedly from other members in external morphology and mtDNA cytochrome b sequence data, suggesting its status should be reinvestigated. Current classification places it in its own monotypic genus Radjah.

Both the male and female of the species are mostly white, with dark wing-tips and a distinctive "collar" of dark feathers. When viewed from above, during flight or with wings outstretched, green bands are visible on the tops of their wings. To communicate, the female utters a harsh rattle while the male emits a breathy, “sore-throat” whistle.

The radjah shelduck inhabits the mangrove forests and coastline of New Guinea (West Papua and Papua New Guinea) and Australia, and some of the Moluccas in eastern Indonesia. In Australia, its primary range is coastal, tropical northern Australia, extending as far south as central Queensland, west through the upper regions of the Northern Territory (including Kakadu National Park) to the Kimberley in Western Australia. The radjah shelduck is listed as a protected bird in all the states of Australia, and penalties are enforced for harming or disturbing them.

The species prefers the salty waters of mangrove flats and paperbark tree swamps, but will visit all manner of brackish and freshwater swamps, lagoons, lakes, estuaries, river deltas, and billabongs further inland during the wet season.

The radjah shelduck forms long-term pair-bonds, and is usually encountered in lone pairs or small flocks. During the wet season the males commonly become very irritable, and have been observed attacking their mates.

The diet consists mainly of mollusks, insects, sedge materials and algae. Pairs start searching for nesting sites during the months of January and February. They nest close to their primary food source, often in the hollow limbs of trees, which makes habitat destruction a particular issue.

The radjah shelduck does not use nesting materials except for some self-supplied down feathers. Egg-laying is usually done by May or June, but depends on the extent of the wet season. The clutches range from 6 to 12 eggs. Incubation time is about 30 days.

12-8-2016 ULAL DE BALDOVI, VALENCIA - LITTLE BITTERN (Ixobrychus minutus)

The little bittern or common little bittern (Ixobrychus minutus ) is a wading bird in the heron family, Ardeidae. Ixobrychus is from Ancient Greek ixias, a reed-like plant and brukhomai, to bellow, and minutus is Latin for "small".

The little bittern has a length of 33–38 centimetres (13–15 in) and a wing span of 52–58 centimetres (20–23 in). It is the smallest of the breeding herons of Europe and is characterised by its tiny size, long and sharp bill and thick neck. The males are distinctively patterned and both sexes show pale forewing panels. The males have black with a faint green sheen on the crown, nape, back, tail and scapulars. The underparts are pale buff and the wing has a pinkish buff oval shaped panel which contrasts with the otherwise black wings and is formed by the inner wing coverts. The underwing is completely whiteish in colour. The female is duller than the male and has brownish black upperparts with paler feather margins visible at close range. The underparts of the female are not as clean as those of the male and are streaked with dark buff and brown. The female's wing panel is less obvious than the male's. The juveniles are duller and more rufous than the females and are more heavily streaked on both their upperparts and underparts, including their wing coverts.

12-8-2016 TANCAT DE PIPA, VALENCIA - GREY HERON (Ardea cinerea)

Grey herons are the largest birds most of us ever see in our garden: the wing span is around 6ft.

Despite their size, they are surprisingly light, weighing on average only half as much as a greylag goose.

The old English name for a heron was hragra; other names now largely fallen into disuse include harn, hernser and hernshaw. Heron comes from the French, for the French name is héron céndre.

In medieval times the heron was a favourite quarry of falconers who valued its great flying skills and ability to evade the falcon's stoops.

Roast herons were also popular at medieval banquets: the young birds, called branchers, were thought to be the best to eat.

The fat of a heron killed at full moon was once believed to be a cure for rheumatism.

Herons are sociable birds when nesting, invariably nesting in long-established heronries.

Most heronries are in trees, with the majority of nests at least 25m above the ground. However, reed-bed heronries are not unusual, and they will also nest on cliffs, bushes, sometimes even on buildings of bridges.

Heronries can reach a prodigious size: one at Great Snowden's Wood, near Brede in Sussex, contained around 400 nests in 1866.

The biggest heronry in Britain is currently at Northward Hill in Kent, an RSPB reserve. Numbers here have peaked at over 200 nests, but the current total is around 150.

It's not unusual for a single tree to hold as many as 10 nests.

The annual count of heronries is the British Trust for Ornithology's longest running survey. The first took place in 1928.

It's quite normal for herons, disturbed at their nest, to regurgitate their last half-digested meal, an unpleasant experience for anyone unfortunate enough to be underneath the nest.

An increasing number of British heronries now also have little egrets nesting alongside the herons.

Herons are among the earliest nesters. It's not unusual for some birds to lay their first eggs in early February, though the normal start is early March, peaking at the end of the month.

The number of herons breeding in Britain and on the Continent has been growing steadily for many years.

They suffer badly in cold winters when ponds and streams are frozen for prolonged periods. The recent run of mild weathers has helped boost the population.

Grey herons are widely distributed, occurring throughout much of Asia as far east as Japan. They also breed in South Africa, while migrants are regular throughout much of Africa.

Only 3.3% of British-ringed herons have been recovered overseas, with the most distant recoveries in Morocco and the Gambia.

Persuading marauding herons not to raid goldfish ponds is very difficult. The only 100% effective protection is netting the pond.

The glossy ibis (Plegadis falcinellus ) is a water bird in the order Pelecaniformes and the ibis and spoonbill family Threskiornithidae. The scientific name derives from Ancient Greek plegados and Latin, falcis, both meaning "sickle" and referring to the distinctive shape of the bill.

The Glossy ibis is a medium-sized wading bird. They have long, slender, down-curved bill and magnificent plumage with shiny feathers. Breeding adults have reddish-brown bodies and shiny bottle-green wings. Non-breeders and juveniles have duller bodies. These birds have dark facial skin bordered above and below in blue-gray (non-breeding) to cobalt blue (breeding) and red-brown legs.

The Glossy ibis is the most widespread ibis species; it breeds in warm regions of Europe, Asia, Africa, Australia, and the Atlantic and Caribbean regions of the Americas. This species is migratory; most European birds winter in Africa, and in North America birds from north of the Carolinas winter farther south. Though generally suspected to be a migratory species in India, the Glossy ibis is a resident in western India. Birds from other populations may disperse widely outside the breeding season. Glossy ibises inhabit wetlands with tall dense stands of emergent vegetation such as reeds, papyrus or rushes, and low trees or bushes. They show a preference for marshes at the margins of lakes and rivers but can also be found at lagoons, flood-plains, wet meadows, swamps, reservoirs, sewage ponds, paddies, and irrigated farmland. These birds are less commonly found in coastal locations such as estuaries, deltas, salt marshes, and coastal lagoons.

12-8-2016 ULLAL DE BALDOVI, VALENCIA - GREATER WHITETHROAT (Sylvia communis)

The common whitethroat or greater whitethroat (Curruca communis) is a common and widespread typical warbler which breeds throughout Europe and across much of temperate western Asia. This small passerine bird is strongly migratory, and winters in tropical Africa, Arabia, and Pakistan.

This is a bird of open country and cultivation, with bushes for nesting. The nest is built in low shrub or brambles, and 3–7 eggs are laid. Like most warblers, it is insectivorous, but will also eat berries and other soft fruit.

In Europe, western and eastern populations of common whitethroats have contrasting moulting and pre-migratory fueling strategies to capitalise on food supplies before departing their breeding and non-breeding grounds.

3-9-2015 VILLALONGA RESERVOIR, VALENCIA - SQUACCO HERON (Ardeola ralloides)

The squacco heron (Ardeola ralloides) is a small heron, 44–47 cm (17+1⁄2–18+1⁄2 in) long, of which the body is 20–23 cm (8–9 in), with 80–92 cm (31+1⁄2–36 in) wingspan. It is of Old World origins, breeding in southern Europe and the Greater Middle East.

The squacco heron is a migrant, wintering in Africa. It is rare north of its breeding range. The species has been recorded in Fernando de Noronha islands, and more rarely in mainland South America, as a vagrant. This is a stocky species with a short neck, short thick bill and buff-brown back. In summer, adults have long neck feathers. Its appearance is transformed in flight, when it looks very white due to the colour of the wings.

The squacco heron's breeding habitat is marshy wetlands in warm countries. The birds nest in small colonies, often with other wading birds, usually on platforms of sticks in trees or shrubs. Three to four eggs are laid. They feed on fish, frogs and insects.

The English common name squacco comes via Francis Willughby (c. 1672) quoting a local Italian name sguacco. The current spelling comes from John Hill in 1752.

The scientific name comes from Latin ardeola, a small heron (ardea), and ralloides, Latin rallus, a rail and Greek -oides, "resembling".

The Squacco Heron uses freshwater localities throughout Europe and the Middle East as breeding grounds to later migrate south to the Sub-Saharan African region. Non-breeding Squacco Herons share similar traits with other heron species like the Indian Pond Heron and Malagasy Pond Heron which show tawny color plumage, lighter streaking, smaller bill, and narrower wing tips.

Small stout heron; favors freshwater marshes, lakes, and ponds with reeds and other surrounding vegetation. Tends to hunt rather sluggishly, hunched quietly at the edge of the water. At rest, appears buffy brown overall, but in flight transforms to mostly white when white wings and tail are revealed. Breeding adult has a rich buffy neck; nonbreeding and immature have a streaked neck.

3-9-2015 VILLALONGA RESERVOIR, VALENCIA - LITTLE EGRET (Egretta garzetta)

The little egret is a small, hyperactive ‘white heron’ with a slender black bill. First recorded from New Zealand in 1944, there are 2-3 little egrets present here most years, with single birds often staying at the same site for many consecutive years.                          

The little egret is a small entirely white heron, with yellow facial skin and a rapier-like black bill. Its legs and bill are black, with yellow soles to its long toes. In breeding plumage, a pair of long, slender plumes grow from the back of the head, curving elegantly down to the back, and filamentous plumes develop on the lower back and breast. The facial skin turns bright red or blue when breeding, but this has not been reported in New Zealand. Juvenile birds have greenish-black legs and duller yellow feet.

The little egret is widely distributed throughout the tropical and warm temperate regions of Europe, Africa, Asia, and Australia. It is reasonably common in most states of Australia but is listed as threatened in Victoria. The main threats to little egrets elsewhere are from coastal reclamation and wetland draining, especially in its feeding and breeding areas of Asia. In New Zealand, little egrets occur almost exclusively in estuarine habitats.

10-8-2016 MONTE CORONA, ADOR - THE PASSENGER MOTH (Dysgonia algira)

Dysgonia algira, the passenger, is a moth of the family Noctuidae. The species was first described by Carl Linnaeus in 1767 and is found in the Palearctic - from the southern half of Europe and parts of North Africa through West, Central and South Asia.

O. algira L. (= achatina Sulz., triangularis Hbn) Forewing brownish fuscous, with a purplish tinge when fresh; a whitish median band narrowed in middle, edged inwardly by the erect but slightly outcurved inner line, outwardly by the similarly incurved median line: outer line acutely angled outwards on vein 6 and bluntly bent between veins 3 and 4. then sinuous to inner margin near median line; a black apical streak of two spots; the terminal area violet grey: hindwing fuscous, with a diffuse whitish median band: the terminal area grey at middle: fringe grey, below apex whitish; the ab. mandschuriana Stgr.[ now full species Dysgonia mandschuriana (Staudinger, 1892) ] is more uniformly purplish or slaty grey, with the median band only slightly paler, not white. Larva yellowish grey, darker on dorsum, with tine black longitudinal lines; venter and feet pale grey; spiracles black; head yellowish grey. The wingspan is 40–46 mm.

The moth flies from May to August depending on the location. The larvae feed on Rubus and willow.
