14-1-2016 CANAL LES FONTS OLIVA, VALENCIA - MALLARD (MALE) (Anas platyrhynchos)


The mallard (Anas platyrhynchos) is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa. Mallards live in wetlands, eat water plants and small animals, and prefer to congregate in flocks of varying sizes. Unlike many waterfowl, mallards are considered an invasive species in some regions. It is a very adaptable species, being able to live and even thrive in urban areas. This species is the main ancestor of most breeds of domestic duck, and its naturally evolved wild gene pool has been genetically polluted by the domestic and feral mallard populations.

The magnificent mallard is one of the most recognizable bird species around the world. When flying, the bird displays a purplish-blue speculum, which is outlined in white. Males of this species are particularly colorful. Breeding males have a yellow beak, dark brown chest, black and white tail as well as bright green head and neck. They exhibit a white ring at the base of their neck. In addition, the sides of breeding males and most of their wings are gray. On the other hand, the plumage of female mallards and non-breeding males is less vivid and colorful. The overall plumage of female mallards is spotted with tan and brown patches, and the head is a lighter tan, showing dark bands near the crown and eyes. Females have orange-colored beaks, covered with dark spots. Females and non-breeding males generally look alike, though the latter have yellowish beaks.

Mallards are found across the Northern and Southern Hemispheres; in North America, their range extends from southern and central Alaska to Mexico, the Hawaiian Islands, across the Palearctic, from Iceland and southern Greenland and parts of Morocco (North Africa) in the west, Scandinavia and Britain to the north, and to Siberia, Japan, and South Korea. Also in the east, it ranges to south-eastern and south-western Australia and New Zealand in the Southern hemisphere. Mallards are strongly migratory in the northern parts of their breeding range and winter farther south. They live in a wide range of habitats and climates, from the Arctic tundra to subtropical regions. They can be found in both fresh- and salt-water wetlands, including parks, small ponds, rivers, lakes, and estuaries, as well as shallow inlets and open seas within sight of the coastline. Water depths of less than 0.9 m (3.0 ft) are preferred, with birds avoiding areas more than a few meters deep. They are attracted to bodies of water with aquatic vegetation.

Mallards are diurnal birds that spend most of their time feeding. They usually feed by dabbling for plant food or grazing. They are highly gregarious outside of the breeding season and form large flocks, which are known as "sordes". However, during the breeding season, both male and female mallards can become aggressive, driving off competitors to themselves or their mate by charging at them. Males typically fight more than females and attack each other by repeatedly pecking at their rival's chest, ripping out feathers and even skin on rare occasions. Females may also carry out 'inciting displays', which encourage other ducks in the flock to begin fighting. In general, mallards are noisy birds. Females have the deep ‘quack’ stereotypically associated with ducks. Males make a sound phonetically similar to that of the female, a typical ‘quack’, but it is deeper and quieter compared to that of the female. When incubating a nest, or when offspring are present, females vocalize differently, making a call that sounds like a truncated version of the usual ‘quack’. In addition, females hiss if the nest or offspring are threatened or interfered with. When taking off, the wings of a mallard produce a characteristic faint whistling noise.

14-1-2016 OLIVA MARJAL, VALENCIA - MALLARD (FEMALE) (Anas platyrhynchos)


The mallard is widely distributed across the Northern and Southern Hemispheres; in North America its range extends from southern and central Alaska to Mexico, the Hawaiian Islands, across the Palearctic, from Iceland and southern Greenland and parts of Morocco (North Africa) in the west, Scandinavia and Britain to the north, and to Siberia, Japan, and South Korea. Also in the east, it ranges to south-eastern and south-western Australia and New Zealand in the Southern hemisphere It is strongly migratory in the northern parts of its breeding range, and winters farther south.


The mallard inhabits a wide range of habitats and climates, from the Arctic tundra to subtropical regions. It is found in both fresh- and salt-water wetlands, including parks, small ponds, rivers, lakes and estuaries, as well as shallow inlets and open sea within sight of the coastline.

16-7-2017 PEGO MARJAL, ALICANTE - COMMON SANDPIPER (Actitis hypoleucos)


The common sandpiper (Actitis hypoleucos ) is a small Palearctic wader. This bird and its American sister species, the spotted sandpiper (A. macularia ), make up the genus Actitis. They are parapatric and replace each other geographically; stray birds of either species may settle down with breeders of the other and hybridize. Hybridization has also been reported between the common sandpiper and the green sandpiper, a basal species of the closely related shank genus Tringa.

The adult is 18–20 cm (7.1–7.9 in) long with a 32–35 cm (13–14 in) wingspan. It has greyish-brown upperparts, white underparts, short dark-yellowish legs and feet, and a bill with a pale base and dark tip. In winter plumage, they are duller and have more conspicuous barring on the wings, though this is still only visible at close range. Juveniles are more heavily barred above and have buff edges to the wing feathers.


This species is very similar to the slightly larger spotted sandpiper (A. macularia ) in non-breeding plumage. But its darker legs and feet and the crisper wing pattern (visible in flight) tend to give it away, and of course they are only rarely found in the same location.

The common sandpiper breeds across most of temperate and subtropical Europe and Asia, and migrates to Africa, southern Asia and Australia in winter. The eastern edge of its migration route passes by Palau in Micronesia, where hundreds of birds may gather for a stop-over. They depart the Palau region for their breeding quarters around the last week of April to the first week of May.


It is a gregarious bird and is seen in large flocks, and has the distinctive stiff-winged flight, low over the water, of Actitis waders.

The common sandpiper forages by sight on the ground or in shallow water, picking up small food items such as insects, crustaceans and other invertebrates; it may even catch insects in flight.


It nests on the ground near freshwater. When threatened, the young may cling to their parent's body to be flown away to safety.

It is widespread and common, and therefore classified as a species of least concern on the IUCN Red List but is a vulnerable species in some states of Australia. The purple sandpiper is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.

16-7-2017 PEGO MARJAL, ALICANTE - 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.

12-7-2017 RACO DE OLLA, VALENCIA - GREATER FLAMINGO (Phoenicopterus roseus)


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.

12-7-2017 ALBUFERA, VALENCIA - BLACK WINGED STILT (Himantopus himantopus)


The Black-winged Stilt, Himantopus himantopus, is a slender wader known for its strikingly long, pink legs and contrasting black-and-white plumage. This elegant bird is a member of the avocet and stilt family, Recurvirostridae.

Adult Black-winged Stilts measure 33–36 cm in length. They possess a long, thin black bill and display a distinctive black and white coloration. The head and neck are predominantly white, with variable black markings depending on the sex and subspecies. Males typically have a glossy or greenish sheen on their black backs, while females exhibit a more brownish tinge. During flight, their long legs trail behind, and their wingbeats are steady.

These birds favor marshes, shallow lakes, and ponds as their breeding grounds. They are also known to inhabit coastal areas during migration and in the winter months.


The Black-winged Stilt has a wide range, extending across Europe, Asia, and Africa. Some populations migrate to coastal regions in winter, while others in milder climates may remain resident or engage in short-range movements.

Black-winged Stilts are often seen foraging in shallow waters, gracefully picking insects and crustaceans from the surface. They are known to nest in small groups, sometimes alongside avocets, and exhibit a variety of courtship behaviors, including intricate displays and duets.

The flight call of the Black-winged Stilt is a sharp and clear kleek, typically heard during its aerial maneuvers.

Nests are simple bare spots on the ground near water. These birds are communal nesters and may breed in loose colonies. They have been known to breed as far north as Britain, with recent successful breeding events recorded in Southern and Northern England.


The Black-winged Stilt can be confused with other stilt species, such as the Black-necked Stilt (H. mexicanus) in the Americas, the White-backed Stilt (H. melanurus), and the Pied Stilt (H. leucocephalus) in Australasia and New Zealand.

Their diet consists mainly of insects and crustaceans, which they deftly pick from the water's surface or from wet sand.

The IUCN lists the Black-winged Stilt as Least Concern, indicating a stable global population. However, they are protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds, highlighting the importance of international cooperation in their conservation.

12-7-2017 RACO DE OLLA, VALENCIA - BLACK WINGED STILT (FEMALE) (Himantopus himantopus)


Black-winged stilts (Himantopus himantopus) are very long-legged wading birds. They are found in both warm and hot climates, feed on small aquatic creatures, and nest on the ground surface in small colonies.

Adult Black-winged stilts have long, pink legs, and a long, rather thin black bill. They are generally black above and white below, with a white head and neck. Males have a black back, often with a greenish gloss or sheen. Females' backs have a brownish hue, contrasting with the black remiges. In populations where the top of the head is normally white (at least in winter), females tend to have less black on the head and neck the entire year round, while males often have much more black, particularly in summer. This difference is not clear-cut, however, and males usually grow all-white head feathers in winter. Immature birds are grey, instead of black, and have a markedly sandy hue on their wings, with light feather fringes appearing as a whitish line in flight.


Black-winged stilts are found across Europe, Asia, Africa, Australia, and North, Central and South Americas. Some populations are migratory and move to the ocean coasts in winter; those in warmer regions are generally resident or short-range vagrants. Black-winged stilts breed in freshwater and brackish marshes, shallow lakes, ponds, and flooded fields. They can also be found in mountainous areas near lakes, river deltas, estuaries, coastal lagoons and marshes, salt meadows, and mudflats.

Black-winged stilts are very gregarious birds. They often gather in groups of around 20 individuals and may migrate or roost in large flocks of several thousand birds. Black-winged tilts are mainly diurnal; however, they are also adapted to nocturnal vision and may also forage even on moonless nights. Black-winged stilts feed in shallow water, wading slowly picking up their food from the water surface or sand.


Black-winged stilts are carnivores (insectivores, molluscivores, vermivores). They eat mainly insects and crustaceans but may also take tadpoles, mollusks, worms, and spiders.

Black-winged stilts are serially monogamous; they form pairs and maintain their bonds only during one breeding season. These birds may nest singly or in loose colonies and each pair defends vigorously their nest site and territory around it. The nest is a bare spot on the ground located near water. The female lays up to 4 eggs which are then incubated for about 3-4 weeks by both parents. Chicks hatch well-developed and can leave the nest within 24 hours. They fledge around 1 month after hatching and become independent 2-4 weeks later. Young Black-winged tilts become reproductively mature and start to breed when they are 1 or 2 years old.

12-7-2017 ULLAL DE BOLDOVI, VALENCIA - RED VEINED DARTER DRAGONFLY (MALE) (Sympetrum fonscolombii)


The red-veined darter or nomad (Sympetrum fonscolombii) is a dragonfly of the genus Sympetrum.
There is genetic and behavioural evidence that S. fonscolombii is not closely related to the other members of the genus Sympetrum and it will at some time in the future be removed from this genus.

Sympetrum fonscolombii was named under the protonym Libellula fonscolombii by the Belgian entomologist Edmond de Sélys Longchamps, in 1840, in honor of the French entomologist Étienne of Fonscolombe (hence the species name). Its name is sometimes spelt fonscolombei instead of fonscolombii but Askew (2004) gives the latter as the correct spelling.


Sympetrum fonscolombii is a widespread and common species in much of central and southern Europe including most Mediterranean islands, North Africa, the Middle East, Mongolia, south-western Asia, including the Indian Subcontinent, the Indian Ocean Islands and Sri Lanka. In Europe it is resident in the south of its range but in some years it migrates northward. From the 1990s onwards has increasingly been found in northwest Europe, including Belgium, Sweden, Finland, Poland, Britain and Ireland. It is the only Libellulidae to be found in the Azores and it is also found on the Canary Islands and Madeira.


It breeds in a wide range of habitats including marshes, lakes, ponds, permanent and seasonal rivers. It is able to recolonize dry areas after a rainfall.


Sympetrum fonscolombii can be seen on the wing throughout the year around the Mediterranean and in the south of its range, however, its main flight period is May to October and it is scarce during the winter months. It is a territorial species with the males often sitting on an exposed perch.

After copulation the pair stay in tandem for egg laying and pairs can be seen over open water with the female dipping her abdomen into the water depositing eggs. Pairs are known to fly over the sea in tandem dipping into the salt water where the eggs soon perish. The eggs and larvae develop within a few months and S. fonscolombii unlike most other European dragonflies has more than one generation a year. Some larvae overwinter.

12-7-2017 ULLAL DE BOLDOVI, VALENCIA - NOMAD DRAGONFLY (FEMALE) (Sympetrum fonscolombii)


The red-veined darter or nomad (Sympetrum fonscolombii) is a dragonfly of the genus Sympetrum.

There is genetic and behavioural evidence that S. fonscolombii is not closely related to the other members of the genus Sympetrum and it will at some time in the future be removed from this genus.[citation needed]

Sympetrum fonscolombii was named under the protonym Libellula fonscolombii by the Belgian entomologist Edmond de Sélys Longchamps, in 1840, in honor of the French entomologist Étienne of Fonscolombe (hence the species name). Its name is sometimes spelt fonscolombei instead of fonscolombii but Askew (2004) gives the latter as the correct spelling.

Sympetrum fonscolombii is a widespread and common species in much of central and southern Europe including most Mediterranean islands, North Africa, the Middle East, Mongolia, south-western Asia, including the Indian Subcontinent, the Indian Ocean Islands and Sri Lanka.

From the 1990s onwards has increasingly been found in northwest Europe, including Belgium, Sweden, Finland, Poland, Britain and Ireland. It is the only Libellulidae to be found in the Azores and it is also found on the Canary Islands and Madeira.


It breeds in a wide range of habitats including marshes, lakes, ponds, permanent and seasonal rivers. It is able to recolonize dry areas after a rainfall.

Sympetrum fonscolombii can reach a body length of 38–40 millimetres (1.5–1.6 in). This species is similar to other Sympetrum species but a good view with binoculars should give a positive identification, especially with a male.

Males have a red abdomen, redder than many other Sympetrum species. The frons and the thorax are red-brown. The eyes are brown above and blue/grey below. The wings have red veins and the wing bases of the hind-wings are yellow. The pterostigma is pale yellow with a border of black veins.

Female are similar but the abdomen is ochre yellow, not red, with two black lines along each side. The wings have yellow veins at the costa, leading edge and base, not red veins as found in the males. The legs of both sexes are mostly black with some yellow.

Immature males are like females but often with more red and a single line along each side of the abdomen.


Male S. fonscolombii can be mistaken for Crocothemis erythraea as both are very red dragonflies with yellow bases to the wings, red veins and pale pterostigma. However C. erythraea has no black on the legs, a broader body and no black on the head. Also C. erythraea females do not oviposit in tandem. The gestalt image of these two species is different and with some experience are easy to tell apart.

Sympetrum fonscolombii can be seen on the wing throughout the year around the Mediterranean and in the south of its range, however, its main flight period is May to October and it is scarce during the winter months. It is a territorial species with the males often sitting on an exposed perch.

After copulation the pair stay in tandem for egg laying and pairs can be seen over open water with the female dipping her abdomen into the water depositing eggs.

12-7-2017 ULLAL DE BOLDOVI, VALENCIA - SPECKLED WOOD BUTTERFLY (Pararge aegeria)


11-10-2015 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.
