12-2-2016 VILLALONGA RESERVOIR, VALENCIA - 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.

11-2-2016 MONTE CORONA - WESTERN CONIFER SEED BUG (Leptoglossus occidentalis)

The western conifer seed bug (Leptoglossus occidentalis), sometimes abbreviated as WCSB, is a species of true bug (Hemiptera) in the family Coreidae. It is native to North America west of the Rocky Mountains (California to British Columbia, east to Idaho Minnesota and Nevada) but has in recent times expanded its range to eastern North America, to include Ontario, Québec, New Brunswick, Nova Scotia, Michigan, Maine, Pennsylvania, New York, Connecticut, Massachusetts, and New Hampshire, and has become an accidental introduced species in parts of Europe and Argentina.

This species is a member of the insect family Coreidae, or leaf-footed bugs, which also includes the similar Leptoglossus phyllopus and Acanthocephala femorata, both known as the "Florida leaf-footed bug". Western conifer seed bugs are sometimes colloquially called stink bugs. While they do use a foul-smelling spray as a defense, they are not classified in the stink bug family Pentatomidae. In Chile, it has been confused with kissing bugs (Triatominae), causing unjustified alarm.

10-2-2016 PEGO MARSHES, ALICANTE - AUDOUIN'S GULL (Ichthyaetus audouinii)

Audouin's gull (Ichthyaetus audouinii ) is a large gull restricted to the Mediterranean and the western coast of Saharan Africa and the Iberian Peninsula. The genus name is from Ancient Greek ikhthus, "fish", and aetos, "eagle", and the specific audouinii and the English name are after the French naturalist Jean Victoire Audouin.

It breeds on small islands colonially or alone, laying 2–3 eggs on a ground nest. As is the case with many gulls, it has traditionally been placed in the genus Larus.

In the late 1960s, this was one of the world's rarest gulls, with a population of only 1,000 pairs. It has established new colonies, but remains rare with a population of about 10,000 pairs.

This species, unlike many large gulls, rarely scavenges, but is a specialist fish eater, and is therefore strictly coastal and pelagic. This bird will feed at night, often well out to sea, but also slowly patrols close into beaches, occasionally dangling its legs to increase drag.

The adult basically resembles a small European herring gull, the most noticeable differences being the short stubby red bill and "string of pearls" white wing primary tips, rather than the large "mirrors" of some other species. The legs are grey-green. It takes four years to reach adult plumage.

This species shows little tendency to wander from its breeding areas, but there were single records in the Netherlands and England in May 2003, and one spent from December 2016 to April 2017 in Trinidad.

The Audouin's gull is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.

Audouin's Gull is undergoing a rapid population reduction following the collapse of the largest breeding colony after several years of very low reproductive output. A reduction in food from fisheries discards coupled with high colony predation is thought to have driven the declines. Despite some of these birds relocating and forming new colonies, overall a rapid decline is believed to have started around 2010. Prior to this populations were increasing, and current population size is estimated to be only around 15% lower than that three generations previously. It is unclear whether the present rate of reduction will persist over the next three generations. As such, the species is assessed as Vulnerable, under criterion A4b.

10-2-2016 PEGO MARSHES, ALICANTE - CATTLE EGRET (Bubulcus ibis)

As the name suggests, cattle egrets can often be seen close to cows, as well as other large grazing mammals. They follow the larger animals around, feeding on the insects and other invertebrates that they disturb. Studies of the diet of cattle egret in other parts of the world have revealed that crickets and grasshoppers are one of their favourite foods, though they will feed on a wide variety of prey, from ticks to frogs. Cattle egrets are sociable birds and prefer to nest in colonies, often mixed in with other herons.

Cattle egrets have shown one of the greatest range expansions in the world of birds. At the beginning of the 20th century, the western form of cattle egret was only established in southern Spain, Portugal and North and tropical Africa. Over the next few decades they spread south to South Africa and began to spread north across Europe. They even managed to cross the Atlantic to reach South America, and have dispersed throughout that continent and up into North America, with breeding recorded as far north as Canada.

Only a few decades ago, cattle egrets were still rare visitors to the UK, until a large influx over the winter of 2007/2008 saw over 200 birds recorded here, mostly in south-west England. This led to the UK's first record of breeding cattle egrets, with at least two pairs nesting in Somerset in the summer of 2008. Since then, they have become an increasingly common sight in the UK and, although still a rare breeding bird here, have nested in several other counties and look likely to become more established.

10-2-2016 PEGO MARSHES, ALICANTE - 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.

11-12-2015 BAGAN, MYANMAR - PIED BUSH CHAT (FEMALE) (Saxicola caprata)

The pied bush chat (Saxicola caprata) is a small passerine bird found ranging from West Asia and Central Asia to the Indian subcontinent and Southeast Asia. About sixteen subspecies are recognized through its wide range with many island forms. It is a familiar bird of countryside and open scrub or grassland where it is found perched at the top of short thorn trees or other shrubs, looking out for insect prey. They pick up insects mainly from the ground, and were, like other chats, placed in the thrush family Turdidae, but are now considered as Old World flycatchers.

They nest in cavities in stone walls or in holes in an embankment, lining the nest with grass and animal hair. The males are black with white shoulder and vent patches whose extent varies among populations. Females are predominantly brownish while juveniles are speckled.

At 13 cm (5.1 in), the pied bush chat is slightly smaller than the Siberian stonechat, Saxicola maurus, although it has a similar dumpy structure and upright stance. The male is black except for a white rump, wing patch and lower belly. The iris is dark brown, the bill and legs black. The female is drab brown and slightly streaked. Juveniles have a scaly appearance on the underside but dark above like the females.

The breeding season is mainly February to August with a peak in March to June. Males sing from prominent perches. The whistling call is somewhat like that of an Indian robin and has been transcribed as we are tea for two with tea at higher note. The nest is built in a hole in a wall or similar site lined with grass and hair, and two to five eggs are laid. Paired males did not reduce their dawn singing behaviour when their mates were trapped and temporarily excluded from the territory. This study suggests that males use dawn chorus to mediate social relationships with neighbouring males to proclaim an established territory. The eggs are small and broadly oval with pale bluish-white or pinkish ground colour and speckles and blotches towards the broad end. They measure about 0.67 by 0.55 inches (1.7 by 1.4 cm). Eggs are incubated chiefly by the female for 12 to 13 days.

Brood parasitism by the common cuckoo (race bakeri) has been noted to be common in the Shan State of Burma, with the cuckoo visiting the nest at dusk and removing an egg before quickly laying its own. The female has dark brown upperparts and rufous underparts and rump. She has no white wing patches. Juveniles are similar to females. Males display during the breeding season by splaying the tail, fluttering and puffing up the white scapular feathers.

This species is insectivorous, and like other chats hunts from a prominent low perch. They have been noted to feed on Pyralid moths and whitefly.

Nematode parasites in the genus Acuaria have been noted. Adult birds have few predators although bats (Megaderma lyra) and wintering Asio flammeus have been noted to prey on them.

12-12-2015 BAGAN, MYANMAR - PIED BUSH CHAT (MALE) (Saxicola caprata)

The pied bush chat (Saxicola caprata) is a small passerine bird found ranging from West Asia and Central Asia to the Indian subcontinent and Southeast Asia. About sixteen subspecies are recognized through its wide range with many island forms. It is a familiar bird of countryside and open scrub or grassland where it is found perched at the top of short thorn trees or other shrubs, looking out for insect prey.

The male is black except for a white rump, wing patch and lower belly. The iris is dark brown, the bill and legs black. The female is drab brown and slightly streaked. Juveniles have a scaly appearance on the underside but dark above like the females.

The pied bush chat is a resident breeder in tropical southern Asia from the Greater Middle East through the Indian subcontinent eastwards to Indonesia. They colonized Papua New Guinea around 1950. It is found in open habitats including scrub, grassland and cultivation.

Some populations are partially migratory. A ringed individual of subspecies rossorum has been recovered from Israel. The populations in India also appear to show seasonal movements but the patterns are unclear. Subspecies bicolor is found in peninsular India in winter. In Karwar on the western coast, it is said to appear in October and stay till May but not seen during the rainy season. Said to be absent in the Baroda district of Gujarat from April to September. Claud Buchanan Ticehurst noted that it was a summer visitor to Baluchistan leaving in October and further that the birds from Baluchistan were indistinguishable from rossorum of Turkestan.

The breeding season is mainly February to August with a peak in March to June. Males sing from prominent perches. The whistling call is somewhat like that of an Indian robin and has been transcribed as we are tea for two with tea at higher note. The nest is built in a hole in a wall or similar site lined with grass and hair, and two to five eggs are laid.

6-2-2016 GANDIA, VALENCIA - CABBAGE WHITE BUTTERFLY (Pieris rapae)

Pieris rapae is a small- to medium-sized butterfly species of the whites-and-yellows family Pieridae. It is known in Europe as the small white, in North America as the cabbage white or cabbage butterfly, on several continents as the small cabbage white, and in New Zealand as the white butterfly. The butterfly is recognizable by its white color with small black dots on its wings, and it can be distinguished from P. brassicae by its larger size and the black band at the tip of its forewings.

The caterpillar of this species, often referred to as the "imported cabbageworm", is a pest to crucifer crops such as cabbage, kale, bok choy and broccoli. Pieris rapae is widespread in Europe and Asia; it is believed to have originated in the Eastern Mediterranean region of Europe, and to have spread across Eurasia thanks to the diversification of brassicaceous crops and the development of human trade routes. Over the past two centuries, it spread to North Africa, North America, New Zealand, and Australia, as a result of accidental introductions.

 

In appearance it looks like a smaller version of the large white (Pieris brassicae). The upperside is creamy white with black tips on the forewings. Females also have two black spots in the center of the forewings. Its underwings are yellowish with black speckles. It is sometimes mistaken for a moth due to its plain appearance. The wingspan of adults is roughly 32–47 mm (1.3–1.9 in).

6-2-2016 GANDIA, 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.

6-2-2016 GANDIA, VALENCIA - COMMON CHAFFINCH (FEMALE) (Fringilla coelebs)

The Eurasian chaffinch, common chaffinch, or simply the chaffinch (Fringilla coelebs) is a common and widespread small passerine bird in the finch family. The male is brightly coloured with a blue-grey cap and rust-red underparts. The female is more subdued in colouring, but both sexes have two contrasting white wing bars and white sides to the tail. The male bird has a strong voice and sings from exposed perches to attract a mate.

The chaffinch breeds in much of Europe, across the Palearctic to Siberia. The female builds a nest with a deep cup in the fork of a tree. The clutch is typically four or five eggs, which hatch in about 13 days. The chicks fledge in around 14 days, but are fed by both adults for several weeks after leaving the nest. Outside the breeding season, chaffinches form flocks in open countryside and forage for seeds on the ground. During the breeding season, they forage on trees for invertebrates, especially caterpillars, and feed these to their young. 

The eggs and nestlings of the chaffinch are taken by a variety of mammalian and avian predators. Its large numbers and huge range mean that chaffinches are classed as of least concern by the International Union for Conservation of Nature.

They are partial migrants; birds breeding in warmer regions are sedentary, while those breeding in the colder northern areas of their range winter further south.

6-2-2016 GANDIA, VALENCIA - EURASIAN BLACKBIRD (MALE) (Turdus merula)

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

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

5-2-2016 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. 

5-2-2016 VILLALONGA RESERVOIR, VALENCIA - 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.

As with all kingfishers, the Common kingfisher is very territorial, mainly because each day it has to eat about 60% of its body weight. They even defend their territory against their mates and offspring. Individuals are solitary for most of the year, roosting in heavy cover beside their favorite hunting spot. When another kingfisher comes into its territory, the birds will both sit on a perch at some distance from one another and perform territorial displays, usually the display of beaks and plumage. Fights occasionally occur, one bird grabbing the other one’s beak and trying to hold their opponent under the water. Their flight is very fast, causing their wings to seem like a blue haze. 

These birds communicate vocally and are well known for a long, trilling call like a repetition of the sound “chee”. During mating, the male whistles loudly to a female and will chase her through and above the trees. When diving for prey, their eyes are covered by a membrane and they rely on touch alone to know when they should snap their jaws shut.

Common kingfishers are serially monogamous and seek a new mate every year. They nest on their own. The female is given food by the male before copulation, usually a fish. 2-3 clutches of eggs are laid yearly, in April, and another by July, with sometimes, a third in early October. Nests are on sandy banks along streams. Sometimes they use a hole in a wall or a rotten tree stump, or a termite mound, where they dig a tunnel and at the end create a nest chamber. 

Both the male and the female work to excavate a 50 to 90-cm-long burrow, taking turns. 6 to 7 white eggs are laid and incubation lasts around 19 to 21 days, done by both parents. Usually, the female does the brooding at night and both parents do it during the day. Young are given food by both their parents and they fledge at about 23-24 days, sometimes more. Four days later they make their first dive. Very soon they become independent and leave the territory where they were born.

The Common kingfisher in most parts of its range is indeed common, but it is under threat from river pollution, disturbances, and human developments. It is also vulnerable to bouts of severe winter weather, as it is unable to feed when bodies of water freeze over.

According to IUCN’s Red List, the global population of the Common kingfisher is around 700,000-1,399,999 mature individuals. Estimates for national populations include: in China, about 10,000-100,000 breeding pairs and 50-10,000 individuals on migration; in Taiwan, 10,000-100,000 breeding pairs; in Korea, 100-10,000 breeding pairs, with 50-1,000 individuals on migration; in Japan, 10,000-100,000 breeding pairs with 50-1,000 individuals on migration, and in Russia, 100-100,000 breeding pairs with 50-10,000 individuals on migration. The European population is estimated at 97,500-167,000 pairs, which equates to 195,000-334,000 mature individuals. Overall, currently, Common kingfishers are classified as Least Concern (LC) on the IUCN Red List.

Common kingfishers serve as a good indicator of the health of an ecosystem. As they feed on small aquatic animals, toxins in the water affect them severely. A strong kingfisher population therefore usually means a healthy habitat. Common kingfishers are also important predators throughout their range of small fish from freshwater habitats, thus controlling their populations.

5-2-2016 VILLALONGA RESERVOIR, VALENCIA - EUROPEAN MOORHEN (FEMALE) (Gallinula chloropus)

The common moorhen (Gallinula chloropus), also known as the waterhen or swamp chicken, is a bird species in the rail family (Rallidae). It is distributed across many parts of the Old World.

The common moorhen lives around well-vegetated marshes, ponds, canals and other wetlands. The species is not found in the polar regions or many tropical rainforests. Elsewhere it is likely the most common rail species, except for the Eurasian coot in some regions.

The closely related common gallinule of the New World has been recognized as a separate species by most authorities, starting with the American Ornithologists' Union and the International Ornithological Committee in 2011.

The moorhen is a distinctive species, with 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. In the related common gallinule (Gallinula galeata) of the Americas, the frontal shield has a fairly straight top and is less wide towards the bill, giving a marked indentation to the back margin of the red area.

The common moorhen gives a wide range of gargling calls and will emit loud hisses when threatened. A midsized to large rail, it can range from 30 to 38 cm (12 to 15 in) in length and span 50 to 62 cm (20 to 24 in) across the wings. The body mass of this species can range from 192 to 500 g (6.8 to 17.6 oz).

This is a common breeding and resident bird in marsh environments, rivers, well-vegetated lakes and even in city parks. Populations in areas where the waters freeze, such as eastern Europe, will migrate to more temperate climates. In China, common moorhen populations are largely resident south of the Yangtze River, whilst northern populations migrate in the winter, therefore these populations show high genetic diversity.

This species will consume a wide variety of vegetable material and small aquatic creatures. 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. Despite loss of habitat in parts of its range, the common moorhen remains plentiful and widespread.

5-2-2016 VILLALONGA RESERVOIR, VALENCIA - CETTI'S WARBLER (Cettia cetti)

Cetti's warbler (Cettia cetti ) is a small, brown bush-warbler which breeds in southern and central Europe, northwest Africa and the east Palearctic as far as Afghanistan and northwest Pakistan. The sexes are alike. The bird is named after the 18th century Italian zoologist, Francesco Cetti. This species is very difficult to see because of its skulking habits.

The Cetti's warbler is approximately 13–14 cm (5.1–5.5 in) from bill to tail. The male weighs 15 g (0.53 oz) and the female 12 g (0.42 oz). Cetti's warbler has a rounded head with a narrow pale grey stripe arching over conspicuous black eyes, and short, rounded wings. The upperparts are a rich chestnut or dark reddish-brown; the throat and breast are pale grey. The tail is longer and broader than many other warblers. The sexes have similar plumage, but males are 26% to 32% heavier than females with a wing-length 11.2% to 13% longer. The male has a wing longer than 60 mm; the female has a wing shorter than 55 mm. The birds can be aged by their plumage; juveniles look similar to adults but have fresh plumage and two dark or dark grey spots on the tongue. Cetti's warbler is unusual among passerine birds in having ten tail feathers (rectrices) rather than the usual twelve.

Cetti's warblers signal their presence with loud song. Their song is distinct, comes in loud bursts, and has a unique structure that allows the birds to avoid mating with other species.

5-2-2016 VILLALONGA RESERVOIR, VALENCIA - MALLARD HYBRID (FEMALE) (Anas platyrhynchos)

The mallard (/ˈmælɑːrd, ˈmælərd/) or wild duck (Anas platyrhynchos) is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa. It 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. Males have green heads, while the females (hens or ducks) have mainly brown-speckled plumage. Both sexes have an area of white-bordered black or iridescent purple or blue feathers called a speculum on their wings; males especially tend to have blue speculum feathers. The mallard is 50–65 cm (20–26 in) long, of which the body makes up around two-thirds the length.

The wingspan is 81–98 cm (32–39 in) and the bill is 4.4 to 6.1 cm (1.7 to 2.4 in) long. It is often slightly heavier than most other dabbling ducks, weighing 0.7–1.6 kg (1.5–3.5 lb). Mallards live in wetlands, eat water plants and small animals, and are social animals preferring to congregate in groups or flocks of varying sizes.

The female lays 8 to 13 creamy white to greenish-buff spotless eggs, on alternate days. Incubation takes 27 to 28 days and fledging takes 50 to 60 days. The ducklings are precocial and fully capable of swimming as soon as they hatch.

2-2-2016 VILLALONGA RESERVOIR - SPOTLESS STARLING (Sturnus unicolor)

The spotless starling (Sturnus unicolor ) is a passerine bird in the starling family, Sturnidae. It is closely related to the common starling (S. vulgaris ), but has a much more restricted range, confined to the Iberian Peninsula, Northwest Africa, southernmost France, and the islands of Sicily, Corsica and Sardinia. It is largely non-migratory.

The spotless starling (Sturnus unicolor ) is a passerine bird in the starling family, Sturnidae. It is closely related to the common starling (S. vulgaris ), but has a much more restricted range, confined to the Iberian Peninsula, Northwest Africa, southernmost France, and the islands of Sicily, Corsica and Sardinia. It is largely non-migratory.

The adult spotless starling is very similar to the common starling, but marginally larger (21–23 cm length; 70–100 g weight), and has darker, oily-looking black plumage, slightly purple- or green-glossed in bright light, which is entirely spotless in spring and summer, and only with very small pale spots in winter plumage, formed by the pale tips of the feathers. It also differs in having conspicuously longer throat feathers (twice the length of those on common starlings), forming a shaggy "beard" which is particularly obvious when the bird is singing. Its legs are bright pink. In summer, the bill is yellow with a bluish base in males and a pinkish base in females; in winter, it is duller, often blackish. Young birds are dull brown, darker than young common starlings, and have a black bill and brown legs. Confusion with the common starling is particularly easy during the winter, when common starlings are abundant throughout the spotless starling's range, but also in summer where their breeding ranges overlap in northeastern Spain and the far south of France. It can also be confused with the common blackbird (Turdus merula ), which differs most obviously in its longer tail and lack of plumage gloss.

Like the common starling, it walks rather than hops, and has a strong direct flight, looking triangular-winged and short-tailed. It is a noisy bird and a good mimic; its calls are similar to the common starling's, but louder.

2-2-2016 VILLALONGA RESERVOIR, VALENCIA - 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.

2-2-2016 MONTE CORONA, VALENCIA - WHITE WAGTAIL (Motacilla alba)

The White wagtail (Motacilla alba) is a small insectivorous bird of the 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 is the national bird of Latvia and has been featured on the stamps of several countries.

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.

1-2-2016 LES FOIS , VALENCIA - WALL BROWN BUTTERFLY (Lasiommata megera)

Lasiommata megera, the wall or wall brown, is a butterfly in the family Nymphalidae (subfamily Satyrinae). It is widespread in the Palearctic realm with a large variety of habitats and number of generations a year.

The species lives in North Africa, Europe, the Caucasus, Asia Minor, the Middle East, western Siberia, northern Tian Shan, Dzungarian Alatau, Kazakhstan and Dzungaria.

Habitats include forest edges and clearings, shrubby areas in ravines and river valleys and sparse woodlands. It is also found in mountain habitats up to 0–3,000 metres (0–9,843 ft) above sea level.

The imago flies from April to October in two or three generations depending on locality and altitude. The larva feeds on grasses in the genera Festuca, Bromus, Deschampsia, Poa, Dactylis and Brachypodium.

31-1-2016 HONG KONG, CHINA - MRS GOULD'S SUNBIRD (Aethopyga gouldiae)

 Mrs. Gould's sunbird (Aethopyga gouldiae) is a sunbird species native to forests and shrublands from the southern foothills of the Himalayas to Southeast Asia.

Mrs. Gould's sunbird is widely distributed in Bangladesh, Bhutan, Laos, Myanmar, Nepal, Thailand, India, Vietnam and Southern China. It is found in the evergreen broad-leaved forest, monsoon forest and deciduous broad-leaved forest at 1000-3500 m above sea-level. It is also occasionally found in orchards and bamboo forest within its range. There is a non-breeding population in Hong Kong.
