22-9-2016 OLIVA MARJAL, VALENCIA - FANTAIL WARBLER (Cisticola juncidis)


The zitting cisticola or streaked fantail warbler (Cisticola juncidis ) is a widely distributed Old World warbler whose breeding range includes southern Europe, Africa (outside the deserts and rainforest), and southern Asia down to northern Australia. A small bird found mainly in grasslands, it is best identified by its rufous rump; as well, it lacks any gold on the collar and the brownish tail is tipped with white. During the breeding season, males have a zigzagging flight display accompanied by regular "zitting" calls that have been likened to repeated snips of a scissor. They build their pouch nest suspended within a clump of grass.

The zitting cisticola is 10 to 12 cm (3.9 to 4.7 in) in length. It is brown above, heavily streaked with black markings. The underparts are whitish, and the tail is broad, white-tipped and flicked frequently, giving rise to the alternative name for the species. The adult males have less crown streaking and more back marking than the females, but there are no great difference between the sexes or the eighteen geographical races. The absence of a nuchal collar separate it from the golden-headed cisticola (Cisticola exilis ). In the non-breeding season, they tend to skulk within the grass and can be hard to spot.


21-9-2016 RIVER JUCAR, VALENCIA - COMMON DARTER DRAGONFLY (FEMALE) (Sympetrum striolatum)


The common darter (Sympetrum striolatum) is a dragonfly of the family Libellulidae native to Eurasia. It is one of the most common dragonflies in Europe, occurring in a wide variety of water bodies, though with a preference for breeding in still water such as ponds and lakes. In the south of its range adults are on the wing all year round.

Sympetrum species are not easy to tell apart and in most areas more than one Sympetrum species will occur. Females and teneral individuals have light yellow thorax and abdomen. Males turn red as they mature. Females darken with age, becoming a dark chocolate brown, and sometimes develop a blue colouration to the bottom of the abdomen. The wings also develop a brown tinge with age. In all cases the legs have a cream or yellow stripe on a black background - this is a diagnostic feature of this species. The pterostigma of the females can be red, blue, pale blue or brown.


Adults can be seen on the wing all year round in southern Europe but in northern regions they occur from June to November.

This small dragonfly is seen in a wide variety of habitats, including lakes, ponds, canals and slow-flowing rivers. They are ambush predators, waiting on a prominent perch - such as a leaf or the top of a gate, until prey fly past, whereupon they will fly after it. They are territorial on breeding waters, often attempting to chase much bigger dragonflies away such as southern hawkers. This habit of repeatedly returning to a sunny spot allows you to easily predict where they are going to land, which is why it is one of the easiest dragonflies to photograph.

In suitable hunting areas away from water, however, they are not territorial: large numbers may assemble - groups of several hundred in a single field have been recorded - and lines of insects can be seen along the top of field gates.

Eggs are not laid, but broadcast from the air: the male holds the female in tandem and swings her down and forward over water. At the furthest point of the arc the female releases some of her eggs to fall on the water.

21-9-2016 RIVER JUCAR, VALENCIA - NOMAD DRAGONFLY (MALE AND FEMALE) (Sympetrum fonscolombii)


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

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


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

21-9-2016 RIVER JUCAR, VALENCIA - EURASIAN GOLDEN ORIOLE (FEMALE) (Oriolus oriolus)


The Eurasian golden oriole (Oriolus oriolus) is the only member of the Old World oriole family of passerine birds breeding in Northern Hemisphere temperate regions. The name "oriole" was first used in the 18th century and is an adaptation of the scientific Latin genus name, which is derived from the Classical Latin "aureolus" meaning golden. Various forms of "oriole" have existed in Romance languages since the 12th and 13th centuries. Albertus Magnus used the Latin form oriolus in about 1250 and erroneously stated that it was onomatopoeic because of the golden oriole's song. In medieval England, its name, derived from the song, was the woodwele.

Males of this species are golden yellow in color with black wings that have yellow-tipped coverts. Females are almost greenish with a yellowish-white belly. Despite the bright colors of males it's quite difficult to spot these birds in the yellow and green leaves of the canopy due to their secretive habits.


Golden orioles breed from western Europe and Scandinavia east to China. They winter in central and southern Africa. These birds live in various habitats. In Western Europe they prefer open broadleaf forests and plantations, copses, riverine forests, orchards, and large gardens; in Eastern Europe, they may inhabit the more continuous forest as well as mixed or coniferous forests. They generally avoid treeless habitats but may forage there. In their wintering habitat, Golden orioles are found in semi-arid to humid woodland, tall forests, riverine forest, woodland/savanna mosaic, and savanna.

Golden orioles are diurnal birds but generally migrate during the night; however, in the spring migration, they may travel during the day. They are usually seen alone, in pairs, or small groups. Golden orioles forage on the ground and in tree canopies using their bills to pick insects out of crevices. These birds communicate with the help of various calls. Their alarm call is a screech like a jay, but the song is a beautiful fluting weela-wee-ooo or or-iii-ole, unmistakable once heard. Breeding pairs often sing in duets when females answer to the males' song with a short skweeeeer.

21-8-2015 MONTE CORONA, VALENCIA - 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).

19-7-2015 GANDIA, VALENCIA - HOUSE SPARROW (FEMALE) (Passer domesticus)


The house sparrow (Passer domesticus) is a bird of the sparrow family Passeridae, found in most parts of the world. It is a small bird that has a typical length of 16 cm (6.3 in) and a mass of 24–39.5 g (0.85–1.39 oz). Females and young birds are coloured pale brown and grey, and males have brighter black, white, and brown markings. One of about 25 species in the genus Passer, the house sparrow is native to most of Europe, the Mediterranean Basin, and a large part of Asia. Its intentional or accidental introductions to many regions, including parts of Australasia, Africa, and the Americas, make it the most widely distributed wild bird.

The house sparrow is strongly associated with human habitation, and can live in urban or rural settings. Though found in widely varied habitats and climates, it typically avoids extensive woodlands, grasslands, polar regions, and hot, dry deserts far away from human development. For sustenance, the house sparrow routinely feeds at home and public bird feeding stations, but naturally feeds on the seeds of grains, flowering plants and weeds. However, it is an opportunistic, omnivorous eater, and commonly catches insects, their larvae, caterpillars, invertebrates and many other natural foods.


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, as well as being a food item and a symbol of lust, sexual potency, commonness, and vulgarity. Though it is widespread and abundant, its numbers have declined in some areas.

23-6-2015 MONTE CORONA, VALENCIA - RHINOCEROS BEETLE (Xyloryctes jamaicensis)


The European rhinoceros beetle (Oryctes nasicornis) is a large flying beetle belonging to the subfamily Dynastinae.

Oryctes nasicornis reach a length of 20–42 millimetres (0.79–1.65 in), with a maximum of 47 millimetres (1.9 in). It is one of the largest beetles found in Europe. Elytra are reddish brown with a glazed appearance, while head and pronotum are slightly darker. The underside of the body and the legs are covered with long red hair. It is a sexually dimorphic species. The male's head is topped by a long curved horn (hence its common name), while the females have no horns.

Oryctes nasicornis inhabits the Palaearctic region, excluding the British Isles. It is the only representative of the Dynastinae family found in Northern Europe. It is widespread in the Mediterranean basin up to Pakistan, the Near East and North Africa.

The rhinoceros beetle lives on wood, and the large larvae can be found in rotting wood stumps and around sawdust. At the margin of its distribution, the beetle is often found in connection with sawmills and horse racing tracks.

The larvae grow in decaying plants feeding on woody debris (xylophagy), generally non-resinous. They can reach a length of 60–100 millimetres (2.4–3.9 in). The development period lasts 2 to 4 years. The adult’s size is influenced by the quality and abundance of food.

The mammoth wasp (Megascolia maculata) is a parasitoid of O. nasicornis larvae. The female wasp lays one egg inside the beetle larva; when the egg hatches, the wasp larva will feed on the host.

The adult beetle emerges between the end of March to May, and lives for a few months until autumn. It occurs mainly during the months of June and July and is very active, flying at dusk and by night, attracted by lights. In this stage they do not feed, consuming only the reserves accumulated during the larval stages.


19-7-2015 VILLALONGA RIO SERPIS, 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.

Lifespan around 4–5 years. Sexual maturity is reached in their second year. Breeding takes place in spring after they wake from winter hibernation. 1-5 eggs are laid, each around 9x15mm, in cracks in rocks or under stones. During development the eggs swell and after 8 weeks when ready to hatch they can be 8x15mm in size. They hatch out around early July. 

They are found in the north-east of the Iberian peninsula, including southern France in parts of the Pyrenees. They are not found above 3400m elevation.

19-9-2016 VILLALONGA RESERVOIR, VALENCIA - 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.

19-9-2016 VILLALONGA RESERVOIR, VALENCIA - LITTLE EGRET (Egretta garzetta)


The little egret (Egretta garzetta) is a species of small heron in the family Ardeidae. It is a white bird with a slender black beak, long black legs and, in the western race, yellow feet. As an aquatic bird, it feeds in shallow water and on land, consuming a variety of small creatures. It breeds colonially, often with other species of water birds, making a platform nest of sticks in a tree, bush or reed bed. A clutch of three to five bluish-green eggs is laid and incubated by both parents for about three weeks. The young fledge at about six weeks of age.

Its breeding distribution is in wetlands in warm temperate to tropical parts of Asia, Africa, Australia, and Europe. A successful colonist, its range has gradually expanded north, with stable and self-sustaining populations now present in the United Kingdom.


In warmer locations, most birds are permanent residents; northern populations, including many European birds, migrate to Africa and southern Asia to over-winter there. The birds may also wander north in late summer after the breeding season, and their tendency to disperse may have assisted in the recent expansion of the bird's range. At one time common in Western Europe, it 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. By the beginning of the 21st century the bird was breeding again in France, the Netherlands, Ireland and Britain. Its range is continuing to expand westward, and the species has begun to colonise the New World; it was first seen in Barbados in 1954 and first bred there in 1994. The International Union for Conservation of Nature has assessed the bird's global conservation status as being of "least concern".


The adult little egret is 55–65 cm (22–26 in) long with an 88–106 cm (35–42 in) wingspan, and weighs 350–550 g (12–19 oz). Its plumage 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.


The breeding range of the western race (E. g. garzetta) includes southern Europe, the Middle East, much of Africa and southern Asia. Northern European populations are migratory, mostly travelling to Africa although some remain in southern Europe, while some Asian populations migrate to the Philippines. The eastern race, (E. g. nigripes), is resident in Indonesia and New Guinea, while E. g. immaculata inhabits Australia and New Zealand, but does not breed in the latter. During the late twentieth century, the range of the little egret expanded northwards in Europe and into the New World, where a breeding population was established on Barbados in 1994. The birds have since spread elsewhere in the Caribbean region and on the Atlantic coast of the United States.

The little egret's habitat varies widely, and includes the shores of lakes, rivers, canals, ponds, lagoons, marshes and flooded land, the bird preferring open locations to dense cover. On the coast it inhabits mangrove areas, swamps, mudflats, sandy beaches and reefs. Rice fields are an important habitat in Italy, and coastal and mangrove areas are important in Africa. The bird often moves about among cattle or other hoofed mammals. 

19-9-2016 VILLALONGA RESERVOIR, VALENCIA - COMMON KINGFISHER (MALE) (Alcedo atthis)


The common kingfisher (Alcedo atthis), also known as the Eurasian kingfisher and river kingfisher, is a small kingfisher with seven subspecies recognized within its wide distribution across Eurasia and North Africa. It is resident in much of its range, but migrates from areas where rivers freeze in winter.

This sparrow-sized bird has the typical short-tailed, large-headed kingfisher profile; it has blue upperparts, orange underparts and a long bill. It feeds mainly on fish, caught by diving, and has special visual adaptations to enable it to see prey under water. The glossy white eggs are laid in a nest at the end of a burrow in a riverbank.

The common kingfisher was first described by Carl Linnaeus in the 10th edition of his Systema Naturae in 1758 as Gracula atthis. The modern binomial name derives from the Latin alcedo, 'kingfisher' (from Greek ἀλκυών, halcyon), and Atthis, a beautiful young woman of Lesbos, and favourite of Sappho.


The genus Alcedo comprises seven small kingfishers that all eat fish as part of their diet. The common kingfisher's closest relative is the cerulean kingfisher that has white underparts and is found in parts of Indonesia. 

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.

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.
