4-6-2014 MONTE CORONA, VALENCIA - CATALONIA WALL LIZARD (Podarcis liolepis)

Podarcis liolepis, the Columbretes wall lizard or Catalan wall lizard, is very similar to the other lizards in the genus Podarcis. This species was formerly described as a subspecies of the Iberian wall lizard, but has now been elevated to species status. These are slender lizards with long tails, narrow tapered heads and long thin toes, and stout legs. Colours are variable, although generally grey-brown. Often very subtle spots and stripes along the back and flanks can be seen and these can be more distinguished in the female. The underside is a much lighter cream or beige with sometimes a reddish tint. Adults grow 15–20 cm in length from the nose to tip of the tail. Body length can be a little as one third of the total body length, the tail making up the other two thirds.

9-7-2014 MONTE CORONA, VALENCIA - WHITE WAGTAIL (Motacilla alba)

The White Wagtail (Motacilla alba) is a small, elegant passerine bird, a member of the family Motacillidae, which includes pipits and longclaws. This slender bird measures between 16.5 to 19 cm in length, with East Asian subspecies reaching up to 21 cm. It is characterized by its long, constantly wagging tail, a behavior that has become synonymous with the genus. Weighing an average of 25 g, the White Wagtail can live up to 12 years in the wild.

Adult White Wagtails exhibit a distinctive plumage with a combination of grey, black, and white. The bird's upper parts are generally grey, with a white face, belly, and breast. Males during the breeding season may show a darker back, and the species is known for its sharp, brisk call and more melodious song during courtship.

The White Wagtail is commonly found in open country, often in close proximity to human habitation and water sources. It shows a preference for bare areas which facilitate the sighting and pursuit of prey. This bird has adapted well to urban environments, utilizing paved areas such as parking lots for foraging.

This species has a vast breeding range across Europe, the Asian Palearctic, parts of North Africa, and has a presence in Alaska. It is a migratory bird, with populations moving to Africa and parts of Asia during the winter. In Great Britain and Ireland, the darker subspecies known as the Pied Wagtail is more prevalent.

The White Wagtail is known for its perpetual tail wagging, a behavior that remains somewhat enigmatic but is thought to be a signal of vigilance to predators. It is a monogamous bird that defends its breeding territory with determination.                                             

9-7-2014 PEGO MARSHES, ALICANTE - NOMAD DRAGONFLY (MALE) (Sympetrum fonscolombii)

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

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 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.

9-6-2014 PEGO MARSHES, ALICANTE - SQUACCO HERON (Ardeola ralloides)

The Squacco Heron is a tawny buff brown heron with a streaked head and back, and in breeding a black and white mane.

Adult: The adult nonbreeding Squacco Heron has a head that is finely streaked in black, brown, and grey, forming a modest crown but no elongated plumes in nonbreeding season. The relatively large and powerful bill is pale green yellow with a black tip and top. The lores are dull yellow green. The irises are yellow. The hind neck, like the head, is finely streaked in black, brown and grey. The upperparts are buff brown with slight tawny tinge. The wings are white and are mostly concealed at rest by the back plumes. The plumes are shorter than in the breeding season. The rump and tail are white. Foreneck and breast are bright buff coarsely streaked in dark brown. The remaining underparts are white. The relatively short legs and the feet are dull yellow green.

In breeding plumage, the upper parts become brighter and deeper. The crown is a mane of yellow buff or straw-colored feathers. The crown feathers are slightly elongated (1-5 cm) and are bordered with black. Several very elongated feathers (13-14 cm long) occur on the back of the crown. These are white bordered with black, and extend over the upper back. The lores are green or blue. The lower neck and back plumes are golden to cinnamon buff. The foreneck and breast are red gold. During courtship, the bill becomes bright blue except for the dark to black tip. The lores turn briefly blue before reverting via emerald to yellow green. The irises in courtship are richer yellow. The back is pink brown, with longest back feathers being golden and drooping over the wings. The legs are bright red in courtship, fading to pink after pairing. The other soft parts colors return to normal after the eggs are laid.

Variation: The sexes are alike. Geographic variation is not recognized taxonomically. South and central African birds were once considered recognized as the subspecies paludivaga.

30-5-2014 SALERNO, ITALY - BARN SWALLOW (Hirundo rustica)

The barn swallow (Hirundo rustica) is a migratory passerine bird, recognized as the most widespread species of swallow in the world. It is a distinctive bird with blue upperparts and a long, deeply forked tail, known for its graceful flight and agile maneuvers. The adult male of the nominate subspecies is 17–19 cm in length, including elongated outer tail feathers, and has a wingspan of 32–34.5 cm. It is adorned with a rufous forehead, chin, and throat, which are set apart from the off-white underparts by a broad dark blue breast band. The outer tail feathers are elongated, contributing to the iconic "swallow tail."

The barn swallow can be identified by its steel blue upperparts, a rufous face, and a dark blue breast band that separates the rufous from the off-white underparts. The deeply forked tail is a key characteristic, with a line of white spots across the upper tail's outer end. Females resemble males but have shorter tail streamers and less glossy blue coloring. Juveniles are browner with paler rufous faces and whiter underparts, lacking the adult's long tail streamers.

The barn swallow favors open country with low vegetation, such as pastures, meadows, and farmland, often near water. It avoids heavily wooded or steep areas and densely built-up locations. The species typically nests in man-made structures like barns and stables, or under bridges and wharves.

This bird has a vast global range, breeding across the Northern Hemisphere and wintering in much of the Southern Hemisphere. Its distribution spans Europe, Asia, Africa, and the Americas.

28-4-2014 JALON, ALICANTE - KNAPWEED FRITILLARY BUTTERFLY (Melitaea phoebe ssp. occitanica)

Melitaea phoebe, the knapweed fritillary, is a butterfly of the family Nymphalidae. It is found in the Palearctic realm, except the northernmost locations. It used to include Melitaea telona, recently revalidated as a distinct cryptic species.

The wingspan is 34–50 mm. M. phoebe. The largest Melitaea of the Old World, at least certain of its forms. The forewing much more pointed than in the previous species; equally variable in colour as well as the distinctness of the markings. The black markings are usually united, in some cases even covering nearly the whole wings, but in other cases may be strongly reduced. It is characteristic for this species that the reddish yellow submarginal lunate spot situated between the two median veins reaches with its vertex considerably farther into the disc than the other yellow lunate spots. This is especially the case on the forewing, but also on the hindwing the submarginal lunule between the 1. and 2. median veins projects farther basad than the others of the same row. Wheeler (1903) gives a short description.

The butterfly flies from April to September depending on the location. The larvae feed on Plantago and Centaurea species (including Centaurea jacea).

Named in the Classical tradition.Phoebe is in Greek mythology is one of the first generation of Titans, who were one set of sons and daughters of Uranus and Gaia.

12-3-2018 VILLALONGA, VALENCIA - SWEET PEA (Section Lathyrus)

Lathyrus /ˈlæθɪrəs/ is a genus of flowering plants in the legume family Fabaceae, and contains approximately 160 species. Commonly known as peavines or vetchlings, they are native to temperate areas, with a breakdown of 52 species in Europe, 30 species in North America, 78 in Asia, 24 in tropical East Africa, and 24 in temperate South America. There are annual and perennial species which may be climbing or bushy. This genus has numerous sections, including Orobus, which was once a separate genus. The genus has numerous synonyms, including Pisum, the ancient Latin name for the pea.

28-1-2014 LORCA, MURCIA - THEKLA LARK (Galerida theklae)

Thekla's lark (Galerida theklae), also known as the Thekla lark, is a species of lark that breeds on the Iberian Peninsula, in northern Africa, and sub-Saharan Africa from Senegal to Somalia. It is a sedentary (non-migratory) species. This is a common bird of dry open country, often at some altitude. Thekla's lark was named by Alfred Edmund Brehm in 1857 for his recently deceased sister Thekla Brehm (1833–1857). The name is a modern Greek one, Θέκλα (Thekla), which comes from ancient Greek Θεόκλεια (Theokleia) derived from θεός (theos, "god") and κλέος (kleos, "glory" or "honour"). The population is declining in Spain, but this is a common bird with a very wide range and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".

This is a smallish lark, slightly smaller than the Eurasian skylark. It has a long, spiky, erectile crest. It is greyer than the Eurasian skylark, and lacks the white wing and tail edge of that species. It is very similar to the widespread crested lark. It is smaller and somewhat greyer than that species, and has a shorter bill. In flight, it shows grey underwings, whereas the crested lark has reddish underwings. The body is mainly dark-streaked grey above and whitish below. The sexes are similar.

Thekla's lark is native and resident in France, Spain, Portugal, Algeria, Egypt, Eritrea, Ethiopia, Kenya, Libya, Morocco, Somalia, Tunisia and Western Sahara. Its typical habitat is rugged areas with scrub, bare patches of ground and semi-arid grassland.

It nests on the ground, laying two to six eggs. Its food is weed, seeds and insects, the latter especially in the breeding season.

The song is melodious and varied, with mournful whistles and mimicry included. It is softer and more tuneful than that of the crested lark, and may be sung during flight or from the ground or an exposed perch.

28-1-2014 MURCIA - BLUE ROCK THRUSH (MALE) (Monticola solitarius)

The blue rock thrush (Monticola solitarius) is a species of chat. This thrush-like Old World flycatcher was formerly placed in the family Turdidae. It breeds in southern Europe, northwest Africa, and from Central Asia to northern China and Malaysia. The blue rock thrush is the official national bird of Malta (the word for it in Maltese being Merill) and was shown on the Lm 1 coins that were part of the country's former currency.

The blue rock thrush is a starling-sized bird, 21–23 cm (8.3–9.1 in) in length with a long slim bill. The breeding male of the nominate subspecies is unmistakable, with all blue-grey plumage apart from its darker wings. Females and immatures are much less striking, with dark brown upperparts, and paler brown scaly underparts. The male of the subspecies M. s. philippensis has rufous-chestnut plumage from the mid-breast down to the undertail. Both sexes lack the reddish outer tail feathers of rock thrush.

The male blue rock thrush sings a clear, melodious call that is similar to, but louder than, the call of the rock thrush.

15-6-2013 HELSINKI, FINLAND - HAZEL GROUSE (Tetrastes bonasia)

The hazel grouse (Tetrastes bonasia), sometimes called the hazel hen, is one of the smaller members of the grouse family of birds. It is a sedentary species, breeding across the Palearctic as far east as Hokkaido, and as far west as eastern and central Europe, in dense, damp, mixed coniferous woodland, preferably with some spruce. The bird is sometimes referred to as "rabchick" (from рябчик) by early 20th century English speaking travellers to Russia.

 

11-6-2013 VILLEFRANCIA, NAVARRA - EUROPEAN GREENFINCH (Chloris chloris)

The European greenfinch or simply the greenfinch (Chloris chloris) is a small passerine bird in the finch family Fringillidae.

This bird is widespread throughout Europe, North Africa and Southwest Asia. It is mainly resident, but some northernmost populations migrate further south. The greenfinch has also been introduced into Australia, New Zealand, Uruguay, and Argentina.

The European greenfinch is 15 cm (5.9 in) long with a wingspan of 24.5 to 27.5 cm (9.6 to 10.8 in). It is similar in size and shape to a house sparrow, but is mainly green, with yellow in the wings and tail. The female and young birds are duller and have brown tones on the back. The bill is thick and conical. The song contains a lot of trilling twitters interspersed with wheezes, and the male has a "butterfly" display flight. Male greenfinch birds exhibit higher degrees of fluctuating asymmetry. The development of bones of males may be more easily disrupted than that of females.

The European greenfinch feeds on a great variety of seeds, berries, fruit, buds, flowers and some arthropods. It forages in trees and bushes, and also on the ground.

12-8-2012 DANUBE DELTA, ROMANIA - GREY HEADED WOODPECKER (Picus canus)

The grey-headed woodpecker (Picus canus), also known as the grey-faced woodpecker, is a Eurasian member of the woodpecker family, Picidae. Along with the more commonly found European green woodpecker and the Iberian green woodpecker, it is one of three closely related sister species found in Europe. Its distribution stretches across large parts of the central and Eastern Palaearctic, all the way to the Pacific Ocean.

The grey-headed woodpecker is more demanding than the European green woodpecker in terms of its habitat. It prefers deciduous forest with a high proportion of dead trees, feeding primarily on ants, although not being as exclusively dependent on this group as the green woodpecker. The grey-headed woodpecker's nest is typically excavated into dead or severely damaged trees.

In the majority of areas for which population numbers are available, the grey-headed woodpecker is in decline. IUCN's Least Concern rating is primarily based on the large distribution of the species.

29-7-2012 SEVASTOPOL, CRIMEA - EURASIAN OYSTERCATCHER (Haematopus ostralegus)

The Eurasian oystercatcher (Haematopus ostralegus) also known as the common pied oystercatcher, or (in Europe) just oystercatcher, is a wader in the oystercatcher bird family Haematopodidae. It has striking black and white plumage, a long straight orange-red bill, red eyes and relatively short dull pink legs. The sexes are similar in appearance but the bill of the female is longer than that of the male.

It is the most widespread of the oystercatchers, with three races breeding in western Europe, central Eurosiberia, Kamchatka, China, and the western coast of Korea. No other oystercatcher occurs within this area.

29-7-2012 SEVASTOPOL, CRIMEA - SYRIAN WOODPECKER (Dendrocopos syriacus)

The Syrian woodpecker (Dendrocopos syriacus) is a member of the woodpecker family, the Picidae.

The woodpecker is a resident breeding bird from southeastern Europe east to Iran. Its range has expanded further northwest into Europe in recent years. It is an inhabitant of open woodlands, cultivation with trees and scrubs, and parks, depending for food and nesting sites upon old trees. It is often an inconspicuous bird, in spite of the plumage.

29-7-2012 SEVASTOPOL, CRIMEA - NORTHERN WHITE BREASTED HEDGEHOG (Erinaceus roumanicus)

The northern white-breasted hedgehog (Erinaceus roumanicus) is a species of hedgehog.

The range of the species extends in the west as far as Poland, Austria and the former Yugoslavia, and south to Greece and the Adriatic Islands, including populations on Crete, Corfu and Rhodes. It is found eastwards through Russia and Ukraine, as far east as the Ob River in Siberia. It is widespread throughout this range, and there are no signs of a significant population decline.

Taxonomically, it was for a time considered to be a subspecies of E. europaeus, and later a subspecies of E. concolor. Since the 1990s, it has been considered a separate species in its own right, following new genetic and morphological studies, with five subspecies - E. roumanicus roumanicus, E. roumanicus bolkayi, E. roumanicus drozdovskii, E. roumanicus nesiotes, and E. roumanicus pallidus.

In Europe, the size of the northern white-breasted hedgehog in southern Europe was greater in comparison to white-breasted hedgehog in northern Europe. The size of the northern white-breasted hedgehog varied based on the temperature and precipitation, the size of the white-breasted hedgehog was larger in higher temperatures. The higher the precipitation, specifically summer precipitation, the smaller the size of the white-breasted hedgehog.

24-7-2012 DANUBE DELTA, ROMANIA - PIED WHEATEAR (Oenanthe pleschanka)

The pied wheatear (Oenanthe pleschanka) is a wheatear, a small insectivorous passerine bird that was formerly classed as a member of the thrush family Turdidae, but is now more generally considered to be an Old World flycatcher (family Muscicapidae). This migratory central Asiatic wheatear occurs from the extreme southeast of Europe to China, and has been found wintering in India and northeastern Africa. It is a very rare vagrant to western Europe.

The male is a boldly marked white-and-black bird. The white crown tinged with brown contrasts with the black face and throat and white rump. The female is browner, and the head is washed with sandy buff. Females are darker than the females of the northern wheatear, look smaller and show less white on the rump. The tail feathers are white with characteristic black markings, which form an inverted black "T" pattern that resembles the tail of the western black-eared wheatear. This 14 centimetres (5.5 in) bird nests in open, stony, sparsely vegetated regions, laying four to six eggs in a hole, under a stone or in a rock crevice. The pied wheatear primarily eats insects but will also take seeds. 

The pied wheatear is native to Southeast Europe and Western Asia. The breeding range extends from Romania and Bulgaria to Siberia, Altai and Mongolia and southwards to the Caucasus, Transcaspia, Turkestan, Iran and Afghanistan. It occurs at altitudes of up to 2,000 metres (6,600 ft) in the Altai and up to 3,000 metres (9,800 ft) in the Tien Shan. It migrates to Northeast Africa, passing through Southwest Asia on the way. In the breeding season it is found in rough open country, steppes with scant vegetation, stony slopes and hilly country. In its winter quarters it is found in similar locations with rock, scree and on plains with thorny scrub. It sometimes visits grassy areas and gardens. It has occurred as a vagrant in Italy, Heligoland and Scotland.

24-7-2012 DANUBE DELTA, ROMANIA - RED BREASTED FLYCATCHER (Ficedula parva)

The red-breasted flycatcher (Ficedula parva) is a small passerine bird in the Old World flycatcher family. It breeds in eastern Europe and across Central Asia and is migratory, wintering in south Asia. It is a regular passage migrant in western Europe, whereas the collared flycatcher which breeds further east is rare. This is because of the different migration direction. The Asian species Ficedula albicilla, previously considered a subspecies of the red-breasted flycatcher, has the red throat surrounded by grey and a different song. It is usually now separated as the taiga flycatcher (Pallas, 1811).

The breeding male of this small 11–12 cm long flycatcher is mainly brown above and white below, with a grey head and orange throat. The bill is black and has the broad but pointed shape typical of aerial insectivores. As well as taking insects in flight, this species hunts caterpillars amongst the oak foliage, and will take berries. The base of the outertail feather is white and the tail is often flicked upwards as they perch looking out for insect prey which are caught on the wing or sometimes from the ground. In winter they are mostly silent but have a typical chip-chip-chr-rrr flycatcher call. In their breeding season, the song consists of melodious whistles, like that of the European pied flycatcher.

Non-breeding males, females and juveniles have brown heads and lack the throat collar, but are easily distinguished from other Ficedula flycatchers on size and the wheatear-like tail pattern, with an inverted dark T against the white tail sides.

They are found mainly deciduous woodlands, especially near water. They build an open nest in a tree hole or similar recess. 4–7 eggs are laid.

Studies on their spring arrivals to the breeding quarters in Poland from 1973–2002 show that males are returning earlier with increasing temperatures.

The genus name is from Latin and refers to a small fig-eating bird supposed to change into the blackcap in winter. The specific parva is Latin for "small".

24-7-2012 DANUBE DELTA, ROMANIA - BLACK WOODPECKER (Dryocopus martius)

The black woodpecker (Dryocopus martius) is a large woodpecker that lives in mature forests across the northern Palearctic. It is the sole representative of its genus in that region. Its range is expanding. The black woodpecker is easily the largest woodpecker species in Europe as well as in the portion of Asia where it lives and is one of the largest species worldwide. This non-migratory species tends to make its home in old-growth forest or large forest stands and excavates a large tree hole to reside in. In turn, several species rely on black woodpeckers to secondarily reside in the holes made in trees by them. This woodpeckers diet consists mostly of carpenter ants. This species is closely related to, and fills the same ecological niche in Europe as, the pileated woodpecker of North America and the lineated woodpecker of South America, also being similar to the white-bellied woodpecker which is distributed to the south somewhat of the black woodpecker in Asia.

24-7-2012 DANUBE DELTA, ROMANIA - BEARDED REEDLING (Panurus biarmicus)

The bearded reedling (Panurus biarmicus) is a small, long-tailed passerine bird found in reed beds near water in the temperate zone of Eurasia. It is frequently known as the bearded tit or the bearded parrotbill, as it historically was believed to be closely related to tits or parrotbills. Today it is known to lack close relatives and it is the only species in the family Panuridae.

The bearded reedling is strongly sexually dimorphic and form life-long pairs. These social birds are highly productive and can breed several times in a season. They mostly feed on small invertebrates in summer and plant seeds in winter.

24-7-2012 DANUBE DELTA, ROMANIA - CORN CRAKE (Crex crex)

The Corn Crake, also known as the Corncrake or Landrail (Crex crex), is a medium-sized bird belonging to the rail family. It exhibits brownish-black upperparts streaked with buff or grey, and its wings are adorned with chestnut markings. The underparts are a blue-grey hue, transitioning to rust-colored and white bars on the flanks and undertail. The bill is a robust, flesh-toned structure, the iris pale brown, and the legs and feet a pale grey. Juveniles resemble adults in plumage, while downy chicks are black, a common trait among rails.

Males are distinguishable by their slightly larger size and more vivid upperparts compared to females. The Corn Crake's distinctive chestnut wing coverts and barred flanks aid in its identification. In flight, it reveals white edges on the inner wing and its legs dangle characteristically.

The Corn Crake favors grasslands, particularly hayfields for breeding, and similar environments during winter migration. It avoids very wet habitats and prefers areas with vegetation that is not too tall or dense to walk through.

This species breeds across Europe and Asia, extending to western China, and migrates to Africa for the Northern Hemisphere's winter. Its range includes lowlands and upland regions, with some populations nesting at high altitudes.

The Corn Crake is a secretive bird, often hidden within vegetation. It exhibits a high-stepping walk and can run swiftly through grass. When disturbed, it may take a weak, fluttering flight but is capable of stronger flight over longer distances, such as during migration.

24-7-2012 DANUBE DELTA, ROMANIA - RED NECKED GREBE (Podiceps grisegena)

The red-necked grebe (Podiceps grisegena) is a migratory aquatic bird found in the temperate regions of the northern hemisphere. Its wintering habitat is largely restricted to calm waters just beyond the waves around ocean coasts, although some birds may winter on large lakes. Grebes prefer shallow bodies of fresh water such as lakes, marshes or fish-ponds as breeding sites.

The red-necked grebe is a nondescript dusky-grey bird in winter. During the breeding season, it acquires the distinctive red neck plumage, black cap and contrasting pale grey face from which its name was derived. It also has an elaborate courtship display and a variety of loud mating calls. Once paired, it builds a nest from water plants on top of floating vegetation in a shallow lake or bog.

Like all grebes, the Red-necked is a good swimmer, a particularly swift diver, and responds to danger by diving rather than flying. The feet are positioned far back on the body, near the tail, which makes the bird ungainly on land. It dives for fish or picks insects off vegetation; it also swallows its own feathers, possibly to protect the digestive system. The conservation status of its two subspecies—P. g. grisegena found in Europe and western Asia, and the larger P. g. holboelii (formerly Holbœll grebe), in North America and eastern Siberia—is evaluated as Least Concern, and the global population is stable or growing.

24-7-2012 DANUBE DELTA, ROMANIA - MARSH FROG (Pelophylax ridibundus)

The marsh frog (Pelophylax ridibundus) is a species of water frog native to Europe and parts of western Asia.

The marsh frog is the largest type of frog in most of its range, with males growing to a size around 100 mm (3.9 in) SVL and females slightly larger (4 in) SVL.[4] There is a large variation in colour and pattern, ranging from dark green to brown or grey, sometimes with some lighter green lines; a lighter line on the back is generally present. The frog will usually be darker coloured in early spring to absorb heat more efficiently.

Tadpoles can reach up to 190 mm (7.3 in) in length, but this usually occurs in places with long winters where the tadpole has time to grow.

They occur in a large part of Europe starting from western France and spreading out into the Middle East and about a quarter into Russia. There are also isolated populations in Saudi Arabia and the Russian Far East, along with some introduced populations in the United Kingdom and other places.

These frogs are very lenient in their habitats, and are able to inhabit a majority of different types of water bodies. Marsh frogs hibernate during the winter either underwater or in burrows, and are able to use the magnetic field of the Earth to locate breeding ponds.

Adult marsh frogs have a large head that is able to devour a wide variety of prey, mostly arthropods and other invertebrates, as well as small fish, other amphibians (including conspecifics), reptiles, small birds, and rodents. In an analysis of 53 adults in Thrace, flies made up 40% and beetles 20% of their diet. These frogs have been found to climb onto water buffalo so they could eat the flies attracted to it, hinting at a possible mutualistic relationship.

As tadpoles, they eat a wide range of organic matter including algae, detritus, decaying plants, invertebrates, and dead animals.

 In places where they were introduced, marsh frogs may pose a threat to the native Pelophylax by diluting the gene pool, but there is evidence that although they may hybridize they do not affect the overall population that greatly.

24-7-2012 DANUBE DELTA, ROMANIA - THRUSH NIGHTINGALE (Luscinia luscinia)

The thrush nightingale (Luscinia luscinia), also known as the sprosser, is a small passerine bird that was formerly classed as a member of the thrush family Turdidae, but is now more generally considered to be an Old World flycatcher, Muscicapidae. It, and similar small European species, are often called chats.

It is a migratory insectivorous species breeding in forests in Europe and the Palearctic and overwintering in Africa. The distribution is more northerly than the very closely related common nightingale, Luscinia megarhynchos, which it closely resembles in appearance. It nests near the ground in dense undergrowth.

The thrush nightingale is similar in size to the European robin. It is plain greyish-brown above and white and greyish-brown below. Its greyer tones, giving a cloudy appearance to the underside, and lack of the common nightingale's obvious rufous tail side patches are the clearest plumage differences from that species. Sexes are similar. It has a similar but more powerful song than that of the nightingale.

24-7-2012 DANUBE DELTA, ROMANIA - RING OUZEL (Turdus torquatus)

The ring ouzel (Turdus torquatus) is a mainly European member of the thrush family Turdidae. It is a medium-sized thrush, 23–24 centimetres (9.1–9.4 in) in length and weighing 90–138 grams (3.2–4.9 oz). The male is predominantly black with a conspicuous white crescent across its breast. Females are browner and duller than males, and young birds may lack the pale chest markings altogether. In all but the northernmost part of its range, this is a high-altitude species, with three races breeding in mountains from Ireland east to Iran. It breeds in open mountain areas with some trees or shrubs, the latter often including heather, conifers, beech, hairy alpenrose or juniper. It is a migratory bird, leaving the breeding areas to winter in southern Europe, North Africa and Turkey, typically in mountains with juniper bushes. The typical clutch is 3–6 brown-flecked pale blue or greenish-blue eggs. They are incubated almost entirely by the female, with hatching normally occurring after 13 days. The altricial, downy chicks fledge in another 14 days and are dependent on their parents for about 12 days after fledging.

The ring ouzel is omnivorous, eating invertebrates, particularly insects and earthworms, some small vertebrates, and a wide range of fruit. Most animal prey is caught on the ground. During spring migration and the breeding season, invertebrates dominate the adult's diet and are also fed to the chicks. Later in the year, fruit becomes more important, particularly the common juniper.

With an extensive range and a large population, the ring ouzel is evaluated as least concern by the International Union for Conservation of Nature (IUCN). There are signs of decline in several countries; suspected causes including climate change, human disturbance, hunting and outdoor leisure activities. Loss of junipers may also be a factor in some areas. Natural hazards include predation by mammalian carnivores and birds of prey, and locally there may also be competition from other large thrushes such as the common blackbird, mistle thrush and fieldfare.

 

24-7-2012 DANUBE DELTA, ROMANIA - EURASIAN SISKIN (Spinus spinus)

 The Eurasian siskin (Spinus spinus) is a small passerine bird in the finch family Fringillidae. It is also called the European siskin, common siskin or just siskin. Other (archaic) names include black-headed goldfinch, barley bird and aberdevine. It is very common throughout Europe and Eurosiberia. It is found in forested areas, both coniferous and mixed woodland where it feeds on seeds of all kinds, especially of alder and conifers.

It can be distinguished from other similar finches by the colour of the plumage. The upper parts are greyish green and the under parts grey-streaked white. Its wings are black with a conspicuous yellow wing bar, and the tail is black with yellow sides. The male has a mainly yellow face and breast, with a neat black cap. Female and young birds have a greyish green head and no cap. It is a trusting, sociable and active bird. The song of this bird is a pleasant mix of twitters and trills. For these reasons it is often raised in captivity.

These birds have an unusual migration pattern as every few years in winter they migrate southwards in large numbers. The reasons for this behaviour are not known but may be related to climatic factors and above all the availability of food. In this way overwintering populations can thrive where food is abundant. This small finch is an acrobatic feeder, often hanging upside-down like a tit. It will visit garden bird feeding stations.
