30-3-2016 VILLALONGA RESERVOIR, VALENCIA - LITTLE RINGED PLOVER (Charadrius dubius)


The little ringed plover (Charadrius dubius ) is a small plover. The genus name Charadrius is a Late Latin word for a yellowish bird mentioned in the fourth-century Vulgate. It derives from Ancient Greek kharadrios a bird found in river valleys (kharadra, "ravine"). The specific dubius is Latin for doubtful, since Sonnerat, writing in 1776, thought this bird might be just a variant of common ringed plover.

Adult little ringed plovers have a grey-brown back and wings, a white belly and a white breast with one black neckband. They have a brown cap, a white forehead, a black mask around the eyes with white above and a short dark bill. The legs are flesh-coloured and the toes are all webbed.


This species differs from the larger ringed plover in leg colour, the head pattern, and the presence of a clear yellow eye-ring.

Their breeding habitat is open gravel areas near freshwater, including gravel pits, islands and river edges across the Palearctic including northwestern Africa. They nest on the ground on stones with little or no plant growth. Both males and females take turns incubating the eggs.

They are migratory and winter in Africa. These birds forage for food on muddy areas, usually by sight. They eat insects and worms.


The Little Ringed Plover is a small plover with a distinctive black and white head pattern, similar to the Ringed Plover. It has a black beak and pale (not orange) legs. Close views reveal a distinctive yellow eye-ring. In flight, it shows a plain brown wing without the white wing stripe that Ringed Plover has. It first bred in the UK in 1938 and is now a year-round resident of a large part of England and Wales – thanks to man-made habitats such as gravel pits. It's listed as a Schedule 1 species under The Wildlife and Countryside Act.


A small, rotund wading bird, the Little ringed plover nests on bare gravel around flooded gravel pits, sandy riverbanks and reservoirs. Like other plovers, it forages for invertebrates and crustaceans in a particular way: standing and watching, running forward, pecking, then standing still again. It is a migrant species, arriving in this country in mid-March and leaving again in July.

 
Daintier than the ringed plover, the Little ringed plover has a black bill, pale, creamy-brown legs, and a bright yellow ring around the eye. It is sandy-brown above and white below, with a black chest-band and black bridle markings on the head.

30-3-2016 VILLALONGA RESERVOIR, VALENCIA - BLACK WINGED STILT (JUVENILE) (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.


Striking large black-and-white wader with a thin, straight bill and bright pink legs, found in wetlands with open shallow water throughout much of Africa and Eurasia, often in brackish habitats. Some populations are migratory, departing northerly breeding grounds for warmer southern regions. Often forms noisy colonies on bare ground near water. Essentially unmistakable throughout much of its range, but compare with Pied Stilt in parts of Southeast Asia. Feeds by wading in water, picking from the water surface with its needle-like bill. In flight, long pink legs stick out far beyond the tail. Calls loudly and stridently, especially when alarmed during the breeding season.

The black-winged stilt (Himantopus himantopus) is a widely distributed, very long-legged wader in the avocet and stilt family Recurvirostridae. Its scientific name, Himantopus himantopus, is sometimes used to generalize a single, almost cosmopolitan species. Alternatively, it is restricted to the form that is widespread in Europe, Asia and Africa, which equals the nominate group of H. himantopus sensu lato. Meanwhile, the black-necked (H. mexicanus) and white-backed stilts (H. melanurus) both inhabit the Americas; the pied stilt (H. leucocephalus) ranges from Australasia and New Zealand. Today, most sources accept between one and four actual species. The taxonomic name Himantopus comes from Greek, meaning "strap-foot" or "thong-foot".

30-3-2016 MONTE CORONA, VALENCIA - TIGER MOTH (Arctia fasciata)


Arctia tigrina is a moth of the family Erebidae. It is found on the Iberian Peninsula and the South of France and Italy. The larvae feed on various plants, including Syringa, Euphorbia and Genista species. This species, along with the others of the genus Atlantarctia, was moved to Arctia as a result of phylogenetic research published by Rönkä et al. in 2016.

30-3-2016 MONTE CORONA, VALENCIA - SARDINIAN WARBLER (MALE) (Sylvia melanocephala)


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


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

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

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

30-3-2016 MONTE CORONA - EGYPTIAN BIRD GRASSHOPPER (Anacridium aegyptium)


Anacridium aegyptium, the Egyptian grasshopper or Egyptian locust, is a species of insect belonging to the subfamily Cyrtacanthacridinae.

A fairly common species, the Egyptian grasshopper is present in most of Europe, the Afrotropical realm, eastern Palearctic realm, the Near East, and North Africa, and has recently been observed in Cape Town, South Africa.

These grasshoppers inhabit trees and shrubs, scrub land, maquis, and orchards in warm and bright environments, at an elevation from sea level to 1,500 m.

Anacridium aegyptium is one of the largest European grasshoppers. Adult males grow up to 30–56 mm (1.2–2.2 in) long, while females reach 46–70 mm (1.8–2.8 in) in length. Their bodies are usually gray, brown, or olive-coloured, and their antennae are relatively short and robust. The tibiae of the hind legs are blue, while the femora are orange. The hind femora have characteristic dark marks. They are also easily identified by their characteristic eyes, which have vertical black and white stripes. Their pronota show a dorsal orange stripe and several small white spots. The wings are clear with dark marks.

30-3-2016 MONTE CORONA, VALENCIA - COMMON WOOD PIGEON (Columba palumbus)


The Common wood pigeon (Columba palumbus) is a member of the dove and pigeon family (Columbidae), native to the western Palearctic. It has historically been known as the Ring dove, and is locally known in southeast England as the "culver"; the latter name has given rise to several areas known for keeping pigeons to be named after it, such as Culver Down.

The Common wood pigeon is a large member of the dove and pigeon family. Adult birds bear a series of green and white patches on their necks and a pink patch on their chest. Juvenile birds do not have white patches on either side of the neck. When they are about six months old they gain small white patches on both sides of the neck; these patches gradually enlarge until they are fully formed when the bird is about 6-8 months old. Juvenile birds also have a greyer beak and an overall lighter grey appearance than adults.



Common wood pigeons occur in Europe, Asia, and northern Africa. In the colder northern and eastern parts of Europe and western Asia they are migrants, but in southern and western Europe populations are often abundant residents. Wood pigeons inhabit deciduous or coniferous woodlands, shrubland, and cultivated areas. They are also commonly seen in parks, gardens, towns, and cities.

This species is a folivore, essentially feeding on leaves of various plants. It is a solitary species, harmless to crops. Adults are mainly seen in August and September, but they are active throughout the year. After mating, these grasshoppers overwinter as adults. Spawning occurs in spring just under the soil surface and the nymphs appear in April. These grasshoppers undergo several molts. Nymphs differ from adults in appearance; their color varies from yellow to bright green and ocher and the wings are absent or small, as they are gradually developed after each molt.

Waders exploit the resources of the banks depending on the size of their legs and bills. They do not go into the water beyond what the length of their bill and legs allow them to. Thus, the Little Ringed Plover is one of the least able to enter the water, using only surface water. 

The Little Ringed Plover is resident on Tenerife, Gran Canaria and Fuerteventura, and is a passage migrant to all the other Canary Islands. I have seen several on La Palma in recent years, more frequently at the irrigation basins in Las Martelas (Los Llanos de Aridane).

29-3-2016 VILLALONGA RESERVOIR, VALENCIA - LITTLE EGRET (Egretta garzetta)


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


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

28-3-2016 VILLALONGA RESERVOIR, VALENCIA - HOUSE SPARROW (MALE) (Passer domesticus)


The House sparrow (Passer domesticus) is a small passerine bird found in most parts of the world. The extent of its range makes it the most widely distributed wild bird on the planet. Because of its numbers, ubiquity, and association with human settlements, the House sparrow is culturally prominent. It is extensively, and usually unsuccessfully, persecuted as an agricultural pest. It has also often been kept as a pet and was a food item. Though it is widespread and abundant, its numbers have declined in some areas.
