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.

15-5-2016 MONTE CORONA - EUROPEAN RABBIT (Oryctolagus cuniculus)


The European rabbit is smaller than the European hare and Mountain hare and lacks black ear tips, as well as having proportionately shorter legs. The fur of the European rabbit is generally greyish-brown, but this is subject to much variation. The guard hairs are banded brown and black, or grey, while the nape of the neck and scrotum are reddish. The chest patch is brown, while the rest of the underparts are white or grey. A white star shape is often present on kits' foreheads but rarely occurs in adults. The whiskers are long and black, and the feet are fully furred and buff-coloured. The tail has a white underside, which becomes prominent when escaping danger. This may act as a signal for other rabbits to run. Moulting occurs once a year, beginning in March on the face and spreading over the back. The underfur is completely replaced by October-November. The European rabbit exhibits great variation in colour, from light sandy to dark grey and completely black. Such variation depends largely on the amount of guard hairs relative to regular pelage.

15-5-2016 MONTE CORONA - SPOTTED FLYCATCHER (Muscicapa striata)


Spotted flycatchers are one of our summer migrants that spend the winter in Africa. They are one of the latest migrants to reach us, with a few trickling into the country from late April and most arriving from mid-May.
Despite arriving relatively late, spotted flycatchers manage to rear two broods of young before departing at the end of August. The success of the second clutch is increased by fewer eggs being laid, meaning less mouths to fill. They will nest in gardens but the nest is usually well hidden on ledges or behind climbing plants.

Spotted flycatchers prefer large flying insects, including flies and butterflies. However, if the weather is cool and insects aren’t flying, they will take smaller invertebrates from leaves and branches. If poor weather persists, many nests fail as these smaller invertebrates tend to be eaten by the parents rather than fed to the young.

In order to reduce the chances of their invertebrate prey escaping, spotted flycatchers have a series of modified feathers, like bristles, down the sides of the bill. They have also adapted to catch stinging insects. They rub the sting end on their perch to remove it, making the prey safe to eat.

The spotted flycatcher is red listed due to its rapid and consistent population decline with an 89 per cent decrease between 1967 and 2012. Evidence suggests that this is due to poor annual survival rates of first year birds, but conditions in their wintering grounds in Africa may also have contributed to the decline.

15-5-2016 MONTE CORONA - HOUSE SPARROW (MALE) (Passer domesticus)


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.

15-5-2016 MONTE CORONA, 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.

Tiny with very small, stubby bill. Both sexes are heavily streaked, with yellow rumps. Males have a bright yellow face and breast; this is gray-brown in females. Common in parks, gardens, cities, agricultural areas,and forest edges. Often sings from electricity wires, posts, TV antennas, and the tops of trees. Frantically fast song is often delivered in arcing song flight with "slow motion" wingbeats. Feeds on seeds and sometimes invertebrates.

14-5-2016 - CULLERA, VALENCIA - MALLARD (MALE) (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.

14-5-2016 - CULLERA, VALENCIA - EURASIAN COOT (Fulica atra)


The Eurasian coot (Fulica atra), also known as the Common coot, or Australian coot, is a member of the rail and crake bird family, the Rallidae. It is found in Europe, Asia, Australia, New Zealand, and parts of North Africa. Similar-looking coot species are found throughout the world, with the largest variety of coot species living in South America.

The Eurasian coot is 36–38 cm (14–15 in) in length with a wing-span of 70–80 cm (28–31 in); males weigh around 890 g (31 oz) and females 750 g (26 oz). It is largely black except for the white bill and frontal shield (which gives rise to the phrase "as bald as a coot", in use as early as 1430). As a swimming species, the coot has partial webbing on its long strong toes. The sexes are similar in appearance.

The juvenile is paler than the adult, has a whitish breast, and lacks the facial shield; the adult black plumage develops when about 3–4 months old, but the white shield is only fully developed at about one year old.

12-5-2016 DENIA, ALICANTE - SPECKLED WOOD BUTTERFLY (Pararge aegeria)


The speckled wood (Pararge aegeria) is a butterfly found in and on the borders of woodland areas throughout much of the Palearctic realm. The species is subdivided into multiple subspecies, including Pararge aegeria aegeria, Pararge aegeria tircis, Pararge aegeria oblita, and Pararge aegeria insula. The color of this butterfly varies between subspecies. The existence of these subspecies is due to variation in morphology down a gradient corresponding to a geographic cline. The background of the wings ranges from brown to orange, and the spots are either pale yellow, white, cream, or a tawny orange. The speckled wood feeds on a variety of grass species. The males of this species exhibit two types of mate locating behaviors: territorial defense and patrolling. The proportion of males exhibiting these two strategies changes based on ecological conditions. The monandrous female must choose which type of male can help her reproduce successfully. Her decision is heavily influenced by environmental conditions.

14-9-2015 CUIDAD DE ENCONTADA, CUENCA - ROCK BUNTING (Emberiza cia)


The rock bunting (Emberiza cia) is a passerine bird in the bunting family Emberizidae, a group now separated by most modern authors from the finches, Fringillidae.

The genus name Emberiza is from Old German Embritz, a bunting. The specific cia is from a local Italian name for this bird, from zirlare, "to chirp".

It breeds in northwest Africa, southern Europe east to central Asia, and the Himalayas. It also breeds locally in central Europe. It is partially migratory, with northern populations wintering further south, mainly within the breeding range of the resident southern populations. It is a rare wanderer to western Europe.


The rock bunting breeds in open dry rocky mountainous areas.

This bird is 16 cm in length. The breeding male has chestnut upperparts, unmarked deep buff underparts, and a pale grey head marked with black striping.

The female rock bunting is a washed-out version of the male, with paler underparts, a grey-brown back and a less contrasted head. The juvenile is similar to the female, but with a streaked head.

There are four races differing mainly in the plumage shades, although the subspecies which breeds in Europe, Africa and western Turkey is the only one to show white wing bars.

It lays three to five greyish eggs in a lined nest on the ground or occasionally in a low bush. Its natural food consists of insects when feeding young, and otherwise seeds.

The call is a sharp tseee, and the song is a twittering churrrr-chirrriiii-itt.

12-5-2016 DENIA, ALICANTE - 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.


Outside of the breeding season, their plumage becomes duller, with the upperparts an olive-grey and the black head becoming less rich in colour.

Females are generally duller in appearance than males, with a grey head and a paler reddish eye ring. The throat is white, darkening into a grey-brown belly and flanks, while the upperparts and wings are pale brown. The female’s tail has white outer edges but is otherwise brown.

Juvenile Sardinian warblers resemble adult females, although there is less contrast between the colours, and they are altogether browner, with brownish heads, and buff-brown wing patterning.

12-5-2016 DENIA HARBOUR - EUROPEAN SHAG (JUVENILE) (Phalacrocorax aristotelis)


The European shag or common shag (Gulosus aristotelis ) is a species of cormorant. It is the only member of the monotypic genus Gulosus. It breeds around the rocky coasts of western and southern Europe, southwest Asia and north Africa, mainly wintering in its breeding range except for the northernmost birds. In Britain this seabird is usually referred to as simply the shag. The scientific genus name derives from the Latin for glutton. The species name aristotelis commemorates the Greek philosopher Aristotle.

This is a medium-large black bird, 68 to 78 cm (27 to 31 in) long and with a 95-to-110-centimetre (37 to 43 in) wingspan. It has a longish tail and yellow throat-patch. Adults have a small crest in the breeding season. It is distinguished from the great cormorant by its smaller size, lighter build, thinner bill, and, in breeding adults, by the crest and metallic green-tinged sheen on the feathers. Among those differences are that a shag has a lighter, narrower beak; and the juvenile shag has darker underparts. The European shag's tail has 12 feathers, the great cormorant's 14 feathers. The green sheen on the feathers results in the alternative name green cormorant sometimes being given to the European shag.


It feeds in the sea, and, unlike the great cormorant, is rare inland. It will winter along any coast that is well-supplied with fish.

The European shag is one of the deepest divers among the cormorant family. Using depth gauges, European shags have been shown to dive to at least 45 m (148 ft). European shags are preponderantly benthic zone feeders, i.e. they find their prey on the sea bottom. They will eat a wide range of fish but their commonest prey is the sand eel. Shags will travel many kilometres from their roosting sites in order to feed.

In UK coastal waters, dive times are typically around 20 to 45 seconds, with a recovery time of around 15 seconds between dives; this is consistent with aerobic diving, i.e. the bird depends on the oxygen in its lungs and dissolved in its bloodstream during the dive. When they dive, they jump out of the water first to give extra impetus to the dive.


It breeds on coasts, nesting on rocky ledges or in crevices or small caves. The nests are untidy heaps of rotting seaweed or twigs cemented together by the bird's own guano. The nesting season is long, beginning in late February but some nests are not started until May or even later. Three eggs are laid. Their chicks hatch without down and so they rely totally on their parents for warmth, often for a period of two months before they can fly. Fledging may occur at any time from early June to late August, exceptionally to mid-October.

The shag is a pursuit-diving seabird that feeds predominantly in benthic habitats. Due to the relative ease with which diet samples can be collected from this species (regurgitated food or pellets) and the perceived conflict between the Phalacrocoracidae and fisheries, shag diet competition has been the subject of substantial scientific interest. Evidence collected at one colony, the Isle of May, Scotland, between 1985 and 2014, suggests that shag chick diet composition in this population has diversified in response to ocean warming. Shags also feed on fewer sandeel on windy days, presumably due to the strong effect of wind on flight in this species. The year-round diet of full-grown shags at this colony has also changed over the past 3 decades, from sandeel specialists to an increasingly diverse prey base.

11-5-2016 LAKE BENEARES, VALENCIA - LARGE CARPENTER BEE (Genus Xylocopa)


Carpenter bees are species in the genus Xylocopa of the subfamily Xylocopinae. The genus includes some 500 bees in 31 subgenera. The common name "carpenter bee" derives from their nesting behavior; nearly all species burrow into hard plant material such as dead wood or bamboo. The main exceptions are species in the subgenus Proxylocopa, which dig nesting tunnels in suitable soil.

Many species in this enormous genus are difficult to tell apart; most species are all black, or primarily black with some yellow or white pubescence. Some differ only in subtle morphological features, such as details of the male genitalia. Males of some species differ confusingly from the females, being covered in greenish-yellow fur. The confusion of species arises particularly in the common names; in India, for example, the common name for any all-black species of Xylocopa is bhanvra (or bhomora - ভোমোৰা - in Assamese), and reports and sightings of bhanvra or bhomora are commonly misattributed to a European species, Xylocopa violacea; however, this species is found only in the northern regions of Jammu and Kashmir and Punjab, and most reports of bhanvra, especially elsewhere in India, refer to any of roughly 15 other common black Xylocopa species in the region, such as X. nasalis, X. tenuiscapa, or X. tranquebarorum.

Non-professionals commonly confuse carpenter bees with bumblebees; the simplest rule of thumb for telling them apart is that most carpenter bees have a shiny abdomen, whereas bumblebee abdomens are completely covered with dense hair. Males of some species of carpenter bees have a white or yellow face, unlike bumblebees, while females lack the bare corbicula of bumblebees; the hind leg is entirely hairy.


In several species, the females live alongside their own daughters or sisters, creating a small social group. They use wood bits to form partitions between the cells in the nest. A few species bore holes in wood dwellings. Since the tunnels are near the surface, structural damage is generally minor or superficial. However, carpenter bee nests are attractive to woodpeckers, which may do further damage by drilling into the wood to feed on the bees or larvae.

Carpenter bees have short mouthparts and are important pollinators on some open-faced or shallow flowers; for some they even are obligate pollinators, for example the maypop (Passiflora incarnata) and Orphium, which are not pollinated by any other insects. They also are important pollinators of flowers with various forms of lids, such as Salvia species and some members of the Fabaceae. However many carpenter bees "rob" nectar by slitting the sides of flowers with deep corollae.

Xylocopa virginica is one example of a species with such nectar robbing behavior. With their short labia the bees cannot reach the nectar without piercing the long-tubed flowers; they miss contact with the anthers and perform no pollination. In some plants, this reduces fruit and seed production, while others have developed defence mechanisms against nectar robbing. When foraging for pollen from some species with tubular flowers however, the same species of carpenter bees still achieve pollination, if the anthers and stigmata are exposed together.

11-5-2016 ALCOY, ALICANTE - LARGE CARPENTER BEE (Genus Xylocopa)


Carpenter bees are species in the genus Xylocopa of the subfamily Xylocopinae. The genus includes some 500 bees in 31 subgenera.

Males of some species of carpenter bees have a white or yellow face, unlike bumblebees, while females lack the bare corbicula of bumblebees; the hind leg is entirely hairy.

The wing venation is characteristic; the marginal cell in the front wing is narrow and elongated, and its apex bends away from the costa. The front wing has small stigma. When closed, the bee's short mandibles conceal the labrum. The clypeus is flat.[3] Males of many species have much larger eyes than the females, which relates to their mating behavior.

In the United States, two eastern species, Xylocopa virginica and X. micans, occur. Three more species are primarily western in distribution, X. sonorina, X. tabaniformis orpifex, and X. californica. X. virginica is by far the more widely distributed species.

8-5-2016 MONTE CORONA, VALENCIA - VIOLET CARPENTER BEE (Xylocopa violacea)


Xylocopa violacea, the violet carpenter bee, is the common European species of carpenter bee, and one of the largest bees in Europe. It is also native to Asia.

Like most members of the genus Xylocopa, it makes its nests in dead wood. It is not particularly aggressive, and will attack only if forced to.

The range of Xylocopa violacea extends from Europe eastward across Asia as far as central China, restricted to latitudes above 30 degrees. In India, any all-black species of Xylocopa are referred to by the common name "bhanvra" (or "bhomora" - ভোমোৰা - in Assamese), and reports and sightings of bhanvra are commonly misattributed to this species; however, this species is found only in the northern regions of Jammu and Kashmir and Punjab. Most sightings refer to any of several other common black Xylocopa, such as X. nasalis, X. tenuiscapa, or X. tranquebarorum.

In 2006, Xylocopa violacea was reported from Cardigan, Wales. In 2007, it was found breeding for the first time in England, in Leicestershire. This follows a northwards expansion of its range in France, Germany, and the Channel Islands. In 2010 it was recorded in Northamptonshire and Worcestershire.

Violet carpenter bees hibernate over winter and they emerge in the spring, usually around April or May. Hibernation is undertaken by the adults in wood where there are abandoned nest tunnels. In the late spring or early summer, they may be seen around searching for mates and suitable nesting sites. After mating, the gravid females bore tunnels in dead wood, which is where the name "carpenter bee" comes from, although old nest tunnels may be used.

Like other solitary bees, the female creates the nest alone. The eggs are laid within a series of small cells, each of which is supplied with a pollen ball for the larvae to feed upon. The adults emerge in late summer then hibernate until the following year.

9-5-2016 PEGO MARSHES, ALICANTE - 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.


This species is found mainly in grassland habitats, often near water. Most populations are resident, but some East Asian populations migrate south to warmer areas in winter. In the Himalayas, they ascend to about 1,900 m (6,200 ft) during summer but are below 1,300 m (4,300 ft) in the winter. This species is a rare vagrant to northern Europe, mostly as a spring overshoot. Its European range is generally expanding, although northern populations are especially susceptible to hard winters.

Zitting cisticolas are very small insectivorous birds, sometimes found in small groups. The breeding season is associated with the rains. Two broods a year occur in many regions. Males are generally polygynous, but some are monogamous. The male builds the initial nest structure deep in the grasses, and invites females using a special display. Females that accept the male complete the nest. The nest is made by binding living leaves into the soft fabric of felted plant-down, cobwebs, and grass. The zitting cisticola's nest is a cup shape with a canopy of tied-together leaves or grasses overhead for camouflage; 3–6 eggs are laid. The female incubates the egg. The eggs hatch after about 10 days. More than one brood may be raised. Females change their mates frequently and rarely stay within the same territory, while males are less mobile, maintaining non-overlapping song-territories which shift from day to day. Females can sometimes breed in their first year.

9-5-2016 PEGO MARSHES, VALENCIA - BARN SWALLOW (Hirundo rustica)


The Barn swallow (Hirundo rustica) is the most widespread species of swallow in the world. In fact, it has the largest natural distribution of any of the world's passerines, ranging over 251 million square kilometers globally. In Anglophone Europe it is just called the swallow; in northern Europe, it is the only common species called a "swallow" rather than a "martin".
