29-5-2016 VILLALONGA RESERVOIR - EUROPEAN MOORHEN (Gallinula chloropus)

The Common moorhen (Gallinula chloropus) is a bird species in the rail family (Rallidae) found across many parts of the Old World. These birds live around well-vegetated marshes, ponds, canals, and other wetlands. The word 'moor' as a part of their name is an old sense meaning marsh.

Common moorhens have predominantly black and brown plumage, with the exception of a white under-tail, white streaks on the flanks, yellow legs, and a red frontal shield. The bill is red with a yellow tip. The young are browner and lack the red shield. The frontal shield of the adult has a rounded top and fairly parallel sides; the tailward margin of the red unfeathered area is a smooth waving line.

Сommon moorhens are widespread across Europe, Asia, and Africa. Populations in areas where the waters freeze, such as eastern Europe, will migrate to more temperate climates. In China, Common moorhens are largely resident south of the Yangtze River, whilst northern populations migrate in the winter. These birds live around well-vegetated marshes, ponds, canals, and other wetlands. They can even be found in city parks and urban areas.

Сommon moorhens are diurnal birds that spend their time swimming or walking along the shore. They forage beside or in the water, sometimes walking on lilypads or upending in the water to feed. They are often secretive but can become tame in some areas. Outside of the breeding season, Common moorhens prefer to spend their time alone; however, during the winter they may gather in groups to feed on sheltered lakes and ponds. To communicate with each other, these birds will give a wide range of gargling calls and will emit loud hisses when threatened.

Сommon moorhens are monogamous and territorial. They form pair-bonds that may last for several years. Pairs nest solitarily usually on top of thick mats of aquatic plants but may also nest in trees, shrubs, or on the ground in dense vegetation. Their nest is a wide shallow cup made with dead vegetation and lined with grass and leaves. Laying starts in spring, between mid-March and mid-May in Northern Hemisphere temperate regions. About 8 eggs are usually laid per female early in the season. Incubation lasts about three weeks. The chicks are precocial; they are hatched with eyes open and are covered in blackish down. Both parents incubate and feed the young. They fledge after 40-50 days, become independent usually a few weeks thereafter, and may raise their first brood the next spring.

Сommon moorhens are widespread across their wide range. However, in some areas populations of this species suffer from severe weather, habitat loss, pollution, and hunting. These birds are also sensitive to avian influenza disease and avian botulism which outbreaks can be a threat in the future.

29-5-2016 VILLALONGA RESERVOIR - MALLARD (JUVENILE) (Anas platyrhynchos)

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.

Mallards have a monogamous mating system. However, they widely practice so-called “extra-pair copulation”, and paired males are known to chase females that are not their mates. Nesting starts in April, reaching its peak in May. During this period, mated pairs are seen circling in the evenings low over the habitat and looking for a suitable nesting site. When the site is chosen, the female constructs the nest on the ground, near a water body, laying 9-13 eggs, which are incubated for 26-28 days. Chicks of this species are precocial; once born, they are able to swim, being introduced to water within 12 hours after hatching. Right after mating, male mallards usually leave, gathering into male flocks for molting in early June, while the females stay with the offspring, caring for the chicks for 42-60 days. Both males and females reach reproductive maturity at 1 year of age.

29-5-2016 VILLALONGA RESERVOIR - MALLARD (FEMALE) (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.

29-5-2016 VILLALONGA RESERVOIR - COMMON KINGFISHER (MALE) (Alcedo atthis)

The Common kingfisher (Alcedo atthis) is a small kingfisher widely distributed across Eurasia and North Africa. It is amongst the most colorful birds but despite its extraordinary colors, sometimes the Common kingfisher is difficult to see when it is in a dappled shade, and its colors are also not very obvious in flight. Furthermore, due to its shy nature, the Common kingfisher often remains hidden from a human's eye.

The Common kingfisher has the typical short-tailed, dumpy-bodied, large-headed, and long-billed shape. The adult male of the western European subspecies, A. a. ispida has green-blue upperparts with pale azure-blue back and rump, a rufous patch by the bill base, and a rufous ear patch. It has a green-blue neck stripe, white neck blaze and throat, rufous underparts, and a black bill with some red at the base. The legs and feet are bright red. The female is identical in appearance to the male except that her lower mandible is orange-red with a black tip.

The juvenile is similar to the adult but with duller and greener upperparts and paler underparts. Its bill is black, and the legs are also initially black. Feathers are moulted gradually between July and November with the main flight feathers taking 90-100 days to moult and regrow. Some that moult late may suspend their moult during cold winter weather.

The Common kingfisher occurs throughout Europe and in Asia as far to the east as Japan, and south of the Sahara in Africa. Common kingfishers live year-round in the south, while northern populations fly south in winter away from the freezing water. In temperate regions, these birds inhabit clear, slow-flowing streams and rivers, and lakes with well-vegetated banks. They frequent scrubs and bushes with overhanging branches close to shallow open water in which they hunt. In winter Common kingfishers are more coastal, often feeding in estuaries or harbors and along rocky seashores. Tropical populations are found near slow-flowing rivers, in mangrove creeks, and swamps.

29-5-2016 VILLALONGA RESERVOIR - GREY WAGTAIL (Motacilla cinerea)

Grey wagtails (Motacilla cinerea) are slender ground-feeding insectivorous birds of open country. They are always associated with running water when breeding, although they may use man-made structures near streams for the nest. Outside the breeding season, these birds may also be seen around lakes, coasts, and other watery habitats. Like other wagtails, they frequently wag their tail and fly low with undulations and they have a sharp call that is often given in flight.

The Grey wagtail has a narrow white supercilium and a broken eye ring. The upperparts are grey and the yellow vent contrasting with whitish underparts makes it distinctive. The breeding male has a black throat that is edged by whitish moustachial stripes. They forage singly or in pairs on meadows or on shallow water marshes. They also use rocks in water and will often perch on trees. They have a clear sharp call note and the song consists of trills.

Grey wagtails are widely distributed across the Palearctic region. They are found from western Europe including the British Isles, Scandinavia, and Mediterranean region, and to eastern Europe and northeastern and central parts of Asia. Some populations are migratory and winter in Africa and Asia. Grey wagtails inhabit mountain streams, lakes, and rivers with exposed rocks, canals, farmlands, tea plantations, and even urban areas.

Grey wagtails are active during the day and forage singly or in pairs on meadows or on shallow water marshes. They also use rocks in the water and will often perch on trees. In winter, Grey wagtails often forage along roadsides; when flushed they make a sharp 'chi-cheep' call and fly up further along the road but after some distance turn back to return to the original location. During the winter, these birds also often roost in small groups. They communicate with clear sharp call notes and their song consists of trills.

Grey wagtails are monogamous and form pairs. Their breeding season occurs from April to July. The male performs a display in which he makes short flights up into the air and descends slowly with fluttering flight accompanied by a rapid series of chipping high notes. Grey wagtails place their nests on the ground near fast running streams or rivers on an embankment between stones and roots. In Europe, their nests are often made in holes in manmade structures. The female lays a clutch of 3-6 speckled eggs; these birds may raise multiple broods with declining numbers in the clutch in subsequent broods. The incubation period is about 2 weeks done by both parents. The chicks fledge 2 weeks after hatching but their parents continue to feed them for 2-3 weeks more.

Grey wagtails are not considered globally threatened at present, however, populations in Europe are vulnerable to severe weather conditions.

28-5-2016 MONTE CORONA, ADOR - MOORISH GECKO (Tarentola mauritanica)

Tarentola mauritanica, known as the common wall gecko, is a species of gecko (Gekkota) native to the western Mediterranean area of North Africa and Europe. It has been introduced to Madeira and Balearic Islands, and the Americas (in Montevideo, Buenos Aires and California). A nocturnal animal with a predominantly insectivorous diet, it is commonly observed on walls in urban environments in warm coastal areas; it can be found further inland, especially in Spain where it has a tradition of cohabitation with humans as an insect hunter. A robust species, up to 15 centimetres (5.9 in) long, its tubercules are enlarged and give the species a spiny armoured appearance.

The species was first described by Carl Linnaeus in 1758. It is also known as moorish gecko, crocodile gecko, European common gecko, and, regionally, as osga (in Portuguese), salamanquesa (in Spanish) and dragó (in Catalan).

The Common wall gecko is a small lizard native to the western Mediterranean area of North Africa and Europe. It is commonly observed on walls in urban environments, mainly in warm coastal areas. However, the Common wall gecko can be found further inland, especially in Spain where it has a tradition of cohabitation with humans as insect hunter. This little creature is brownish-grey or brown in color with darker or lighter spots. These colors change in intensity according to the light. When geckos are active by day their color is darker than during the night.

The Eurasian collared dove (Streptopelia decaocto) is a dove species native to Europe and Asia. During the 20th century, the Eurasian collared dove spectacularly expanded its range from the Middle East to right across Europe. Accidentally introduced in 1974 into the Bahamas, this pale chunky bird soon spread to the mainland in Florida. A relative of the mourning dove, its name comes from its black half-collar around its neck.

The Eurasian collared dove is grey-buff to pinkish-grey overall, a little darker above than below, with a blue-grey underwing patch. The tail feathers are grey-buff above, and dark grey and tipped white below; the outer tail feathers are also tipped whitish above. It has a black half-collar edged with white on its nape. The short legs are red and the bill is black. The iris is red, but from a distance, the eyes appear to be black, as the pupil is relatively large and only a narrow rim of reddish-brown iris can be seen around the black pupil. The eye is surrounded by a small area of bare skin, which is either white or yellow. The two sexes are virtually indistinguishable; juveniles differ in having a poorly developed collar, and a brown iris.

The original range of this bird was warmer temperate regions across southeastern Europe and Japan. However, during the twentieth century, it extended across all of Europe, by 1953 reaching Great Britain, and Ireland soon after. Now it also breeds in Scandinavia. In the 1970s it was introduced into the Bahamas, and to Florida in the 1980s, and has gradually colonized the North American continent. Eurasian collared doves do not migrate and live in towns and cities, in urban gardens and parks. In their original range, they typically occur in semi-desert regions with scattered trees, or mixed thickets and orchards.

28-5-2016 BENIARJO, VALENCIA - COMMON HOUSE MARTIN (Delichon urbicum)

The Common house martin (Delichon urbicum) is a migratory passerine bird which breeds in Europe, North Africa and across the Palearctic; and winters in sub-Saharan Africa and tropical Asia. It feeds on insects that are caught in flight, and it migrates to climates where flying insects are plentiful. Both the scientific and colloquial names of the bird are related to its use of human-made structures. It builds a closed cup nest from mud pellets under eaves or similar locations on buildings usually in colonies.

The Common house martin is steel-blue above with a white rump, and white underparts, including the underwings; even its short legs have white downy feathering. It has brown eyes and a small black bill, and its toes and exposed parts of the legs are pink. The sexes are similar, but the juvenile bird is sooty black, and some of its wing coverts and quills have white tips and edgings.

Common house martins breed in Europe, North Africa, and across the Palearctic and winter in sub-Saharan Africa and tropical Asia. They prefer open country with low vegetation, such as pasture, meadows, and farmland, usually near water. They may also be found in mountains and near trees since they provide insect food and also roosting sites. On their wintering grounds, Common house martins use similar open habitats. In the tropical parts of their wintering range, like East Africa and Thailand, they occur mainly in the higher areas.

Common house martins are social birds. They spend most of their day flying for hours hunting their prey. Common house martins hunt at a height of 21 m (69 ft) during the breeding season, typically within 450 m (1,480 ft) of the nest. They will also follow the plough or large animals to catch disturbed insects. On the wintering grounds, they usually hunt at a greater height of over 50 m (160 ft). Common house martins are migrants who move on a broad front, and they usually travel in daylight. They are noisy birds, especially in their breeding colonies. The male's song, given throughout the year, is a soft twitter of melodious chirps. The contact call is a hard 'chirrrp', and the alarm is a shrill 'tseep'.

28-5-2016 BENIARJO, VALENCIA - WESTERN CATTLE EGRET (Bubulcus ibis ssp. ibis)

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.

Cattle egrets are native to parts of Asia, Africa, and Europe but they have undergone a rapid expansion in their distribution and successfully colonized much of the rest of the world in the last century. Many populations of Cattle egrets are highly migratory, while others are dispersive, and distinguishing between the two can be difficult. In many areas, populations can be both sedentary and migratory. In the Northern Hemisphere, migration is from cooler climes to warmer areas, but Cattle egrets nesting in Australia migrate to cooler Tasmania and New Zealand in the winter and return in the spring. Migration in western Africa is in response to rainfall, and in South America, migrating birds travel south of their breeding range in the non-breeding season. Populations in southern India appear to show local migrations in response to the monsoons. Cattle egrets inhabit wetlands, dry grassy habitats, semi-arid steppes, floodplains, freshwater swamps, shallow marshes, and mangroves. They are often found in fields, croplands, and pastures with poor drainage. When nesting, Cattle egrets are found in woodlands near lakes or rivers, in swamps, or on small inland or coastal islands.

Cattle egrets are diurnal, feeding by day and sleeping at night. They are highly social; they feed in flocks and nest in colonies. Cattle egrets share roosting colonies with other colonial waterbirds. Adapted to foraging on land, Cattle egrets have lost the ability possessed by their wetland relatives to accurately correct for light refraction by water. They are usually found with cattle and other large grazing and browsing animals and catch small creatures disturbed by the mammals. Cattle egrets weakly defend the area around a grazing animal against others of the same species, but if the area is swamped by egrets, they will give up and continue foraging elsewhere. Where numerous large animals are present, Cattle egrets selectively forage around species that move at around 5-15 steps per minute, avoiding faster and slower moving herds; in Africa, Cattle egrets prefer to forage behind Plains zebras, Waterbuck, Blue wildebeest, and Cape buffalo. Dominant birds feed nearest to the host and thus obtain more food. Cattle egrets are usually silent but will produce a quiet, throaty ‘rick-rack’ call at the breeding colony.

26-5-2016 MONTE CORONA, ADOR - SPECKLED WOOD BUTTERFLY (Pararge aegeria)

The average wingspan of both males and females is 5.1 cm (2 in), although males tend to be slightly smaller than females. Furthermore, males possess a row of grayish-brown scent scales on their forewings that is absent in the females. Females have brighter and more distinct markings than males. The subspecies P. a. tircis is brown with pale yellow or cream spots and darker upperwing eyespots. The subspecies P. a. aegeria has a more orange background and the hindwing underside eyespots are reddish brown rather than black or dark gray. The two forms gradually intergrade into each other. Subspecies P. a. oblita is a darker brown, often approaching black with white rather than cream spots. The underside of its hindwings has a marginal pale purple band and a row of conspicuous white spots. The spots of subspecies P. a. insula are a tawny orange rather than a cream color. The underside of the forewings has patches of pale orange, and the underside of the hindwing has a purple-tinged band. Although there is considerable variation with each subspecies, identification of the different subspecies is manageable.

26-5-2016 MONTE CORONA, ADOR - LARGE PSAMMODROMUS LIZARD (Psammodromus algirus

Distribution: Iberia excluding the northern Atlantic coastal stretch. South west France.

English name: Large or Algerian Psammodromus

Scientific name: Psammodromus algirus (Linnaeus 1758)

Castilian: Lagartija Colilarga

Family: Lacertidae

When to see them: The Large, or Algerian Psammodromus is the most numerous of the lizard species found in Iberia. They can be active throughout the year if the temperature exceeds 15 degrees, only hibernating in areas where the temperature drops lower than this. They are generally diurnal but may also be out on summer nights.

The Large Psammodromus lizard is a long, slender lizard which has incredible agility and speed. Their tails are very long and slim sometimes up to twice the length of the body, it’s limbs are also long and thin allowing short burst of high speed. It’s head is slightly pointed.

The lizard’s back is a soft milk-chocolate brown colour and there are two creamy -yellow stripes running down each flank. The back legs up to the base of the tail are a soft rust-orange colour. The body scales are somewhat ‘jagged’ keeled, pointed and almost upturned on each scale end.

Their subtle colouration camouflages them in the habitats they frequent, against the soil and dried vegetation under shrubs in forests, woodland or more open scrubland. They may be seen out in the open, but generally stick fairly close to shrubs that they can hunt through and use as cover and shelter.

Psammodromus lizards are very agile and climb nimbly through shrubs and hedges, sometimes giving away their position as they rustle through dry leaves.

This species  adapts readily to a variety of habitats from sea level up to around 2600m in altitude in the warmer southern areas of their distribution range.

Their diet consists mainly of arthropods – beetles, spiders, grasshoppers and ants, they will also eat other small lizards and fruit or seeds.

Breeding begins in the spring and there may be two or rarely three clutches consisting of between 2 to 11 eggs. The incubation time can vary from one to six weeks with the young appearing from August through to October. The young are 2.5 to 3cm in body length and have the same colouration and patterns as the adults. This species may live up to 7 years, reaching their sexual maturity when they are two years old.

25-5-2016 MARJAL DE MOROS, SAGUNTO - COMMON POCHARD (FEMALE)

The common pochard (; Aythya ferina ) is a medium-sized diving duck. The scientific name is derived from Greek aithuia an unidentified seabird mentioned by authors including Hesychius and Aristotle, and Latin ferina, "wild game", from ferus, "wild".

The adult male has a long dark bill with a grey band, a red head and neck, a black breast, red eyes and a grey back. The adult female has a brown head and body and a narrower grey bill-band. The triangular head shape is distinctive. Pochards are superficially similar to the closely related North American redhead and canvasback.

Their breeding habitat consists of marshes and lakes with a metre or more water depth. Pochards breed in much of temperate and northern Europe and across the Palearctic. They are migratory, and spend winter in the south and west of Europe.

In the British Isles, birds breed in eastern England and lowland Scotland, in small numbers in Northern Ireland with numbers increasing gradually, and sporadically in the Republic of Ireland, where it may also be increasing. While uncommon, individuals are also occasionally seen in the south of England, and small populations are sometimes observed on the River Thames. Large numbers stay overwinter in Great Britain, after the birds retreat from Russia and Scandinavia.

25-5-2016 MARJAL DE MOROS, SAGUNTO - COMMON TERN (Sterna hirundo)

The Common tern (Sterna hirundo) is a seabird that has a circumpolar distribution. it has four subspecies breeding in temperate and subarctic regions of Europe, Asia, and North America. Its large population and huge breeding range mean that this species is classed as being of least concern, although numbers in North America have declined sharply in recent decades.

Known for its attractive plumage and graceful flight, Common terns have a slender body and a smoothly rounded head, and long pointed wings. Their breeding plumage is light silvery-gray upperparts and clear black outer primaries on its wingtips. Outside the breeding season, the birds keep some of their distinguishable black cap, but their forehead and face turn white. Their legs and bill turn black, losing their orange-red coloration. Male and female are similar in appearance throughout the year. Juvenile Common terns have pale grey upper wings with a dark carpal bar. The crown and nape are brown, and the forehead is ginger, wearing to white by autumn. The upper parts are ginger with brown and white scaling, and the tail lacks the adult's long outer feathers. Birds in their first post-juvenile plumage, which normally remain in their wintering areas, resemble the non-breeding adult but have a duskier crown, dark carpal bar, and often very worn plumage. By their second year, most young terns are either indistinguishable from adults, or show only minor differences such as a darker bill or white forehead.

26-5-2016 MONTE CORONA, VALENCIA - SHORT TOED TREE CREEPER (Certhia brachydactylba)

The short-toed treecreeper (Certhia brachydactyla ) is a small passerine bird found in woodlands through much of the warmer regions of Europe and into north Africa. It has a generally more southerly distribution than the other European treecreeper species, the common treecreeper, with which it is easily confused where they both occur. The short-toed treecreeper tends to prefer deciduous trees and lower altitudes than its relative in these overlap areas. Although mainly sedentary, vagrants have occurred outside the breeding range.

The short-toed treecreeper is one of a group of four very similar Holarctic treecreepers, including the closely related North American brown creepers, and has five subspecies differing in appearance and song. Like other treecreepers, the short-toed is inconspicuously plumaged brown above and whitish below, and has a curved bill and stiff tail feathers. It is a resident in woodlands throughout its range, and nests in tree crevices or behind bark flakes, laying about six eggs. This common, unwary, but inconspicuous species feeds mainly on insects which are picked from the tree trunk as the treecreeper ascends with short hops.
