19-11-2017 BILLERICAY, ESSEX - EUROPEAN GREEN WOODPECKER (Picus viridis)


The European green woodpecker (Picus viridis ) is a large green woodpecker with a bright red crown and a black moustache. Males have a red centre to the moustache stripe which is absent in females. It is resident across much of Europe and the western Palearctic but in Spain and Portugal it is replaced by the similar Iberian green woodpecker (Picus sharpei ).

The European green woodpecker spends much of its time feeding on ants on the ground and does not often 'drum' on trees like other woodpecker species. Though its vivid green and red plumage is particularly striking, it is a shy bird, and is more often heard than seen, drawing attention with its loud calls. A nest hole is excavated in a tree; four to six eggs are laid which hatch after 19–20 days.

The European green woodpecker is a large green bird with a bright red crown and a black moustache. Despite its striking plumage, it is a shy bird and is more often heard than seen, drawing attention with its loud calls. Both the males and the females are green above and pale yellowish green below, with yellow rump and red crown and nape; the moustachial stripe has a red centre in the male but is solid black in the female. Juveniles are spotty and streaked all over; the moustache is dark initially, though juvenile males can show some red feathers by early June or usually by July or August.


European green woodpeckers are widely distributed in Europe but are absent from some northern and eastern parts and from Ireland, Greenland, and the Macaronesian Islands. They also occur in western Asia. European green woodpeckers don’t migrate and rarely move more than around 500 m between breeding seasons. They prefer old deciduous trees for nesting and nearby feeding grounds with plenty of ants. This is usually found in semi-open landscapes with small woodlands, hedges, scattered old trees, edges of forests, and floodplain forests. They prefer to forage in grasslands, heaths, plantations, orchards, and lawns.

European green woodpeckers can be seen alone, in pairs, or in company with their young. They are active during the day and spend much of their time feeding on ants on the ground and do not often 'drum' on trees like other woodpecker species. They feed mainly on the ground probing ant nests and licking up adult ants and their larvae. European woodpeckers have tongues that wrap to the back of their head. They often forage in short-grazed or mown permanent grasslands where the availability of ant nests is high. Although European green woodpeckers are shy and wary, they usually produce loud calls, known as yaffling, which first draw attention. They 'drum' rarely (a soft, fast roll), but often give a noisy ‘kyü-kyü-kyück’ while flying. The song is a loud series of 10–18 'klü' sounds which gets slightly faster towards the end and falls slightly in pitch. The females make a thinner ‘pü-pü-pü-pü-pü-pü-pü’.

19-11-2017 BILLERICAY, ESSEX - EURASIAN JACKDAW (Corvus monedula)


The Western Jackdaw (Coloeus monedula), a member of the crow family Corvidae, is a passerine bird recognized by its black plumage with a grey nape and distinctive pale-grey irises. Measuring 34–39 centimeters in length, this bird exhibits a combination of black, grey, and iridescent blue or purple hues across its body, depending on the subspecies.

Adult Western Jackdaws have a stout, black bill and legs, with a body mostly cloaked in shiny black feathers. The head features a sheen that can be purple or blue, and the throat, primaries, and tail display a green-blue iridescence. The cheeks, nape, and neck are a contrasting light grey, and the underparts are slate-grey. Juveniles are duller with less distinct plumage and brownish eyes that turn white around one year of age.

Western Jackdaws favor a variety of habitats including wooded steppes, pastures, coastal cliffs, and urban settings. They thrive in environments where forested areas have been cleared, creating open fields and spaces.

This species is widespread across Europe, western Asia, and North Africa. It is mostly resident, but populations in the north and east migrate southward during winter months.


Western Jackdaws are gregarious and social birds, often seen in flocks. They are known for their intelligence and have been observed using tools. Pairs are monogamous and maintain strong bonds within their social groups.

The vocal repertoire of the Western Jackdaw includes a metallic "chyak-chyak" or "kak-kak" call, often heard in flight. They also emit a hoarse, drawn-out alarm call and have the ability to mimic human speech.

These birds are monogamous and build simple nests of sticks in cavities. They lay about five pale blue or blue-green eggs with brown speckles, which are incubated by the female. The young fledge in four to five weeks.
 
An omnivorous and opportunistic feeder, the Western Jackdaw consumes a wide variety of plant material, invertebrates, and food waste. They exhibit various feeding methods, including jumping, pecking, and probing the soil.

18-11-2017 HANNINGFIELD RESERVOIR, ESSEX - NORTHERN LAPWING (Vanellus vanellus)


The Northern Lapwing, known scientifically as Vanellus vanellus, is a distinctive bird with a notable crest on its head. It measures 28–33 cm in length, with a wingspan of 67–87 cm and a body mass ranging from 128–330 g. The species exhibits sexual dimorphism; males have a pronounced crest and a stark black crown, throat, and breast, which contrasts sharply with their white face. Females and juveniles have shorter crests and less defined head markings, but their overall plumage is similar to that of the males, with a black and white coloration and a greenish tint on the back.

When identifying the Northern Lapwing, look for its rounded wings, short legs, and the characteristic crest that adorns its head. The male's long crest and contrasting black and white facial patterns are particularly striking during the breeding season. In flight, the species can be recognized by its slow wingbeats and the rounded shape of its wings.


The Northern Lapwing is a ground-nesting bird that favors open landscapes such as cultivated fields, grasslands, and wetlands. It is adaptable and can be found in a variety of temperate environments across Eurosiberia.

This bird is a widespread resident throughout temperate regions of Eurosiberia. It is highly migratory, wintering in regions as far south as North Africa and parts of Asia. Western European populations are more sedentary, while vagrants have been known to appear in North America following storms.

The Northern Lapwing is known for its acrobatic display flights, accompanied by a cacophony of calls during the breeding season. It migrates predominantly during the day, often in large flocks. The species is fiercely protective of its nest and young, boldly confronting any potential threats. In winter, it gathers in massive flocks on open land, and it is known to feed nocturnally when the moon is bright.

The Northern Lapwing is quite vocal, especially in the breeding season. Its contact call is a loud "pee-wit," which is also the origin of one of its common names. Males perform a display flight while emitting a wheezy "pee-wit, wit wit, eeze wit," and they may also produce squeaking or mewing sounds.

20-11-2017 LAKESIDE THURROCK, ESSEX - BRITISH BLUE TIT (Cyanistes caeruleus ssp. obscurus)

                               

The Eurasian blue tit (Cyanistes caeruleus) is a small passerine bird easily recognizable by its blue and yellow plumage. The bird is famed for its acrobatic skills, as it can cling to the outermost branches and hang upside down when looking for food.

A typical Eurasian blue tit has an azure-blue crown and dark blue line passing through the eye, and encircling the white cheeks to the chin, giving the bird a very distinctive appearance. The forehead and a bar on the wing are white. The nape, wings, and tail are blue and the back is yellowish-green. The underparts are mostly sulphur-yellow with a dark line down the abdomen. The bill is black, the legs bluish grey, and the irides dark brown. The sexes are similar, but under ultraviolet light, males have a brighter blue crown. Young blue tits are noticeably more yellow.





Eurasian blue tits are widespread and common resident breeders throughout temperate and subarctic Europe and in parts of the Middle East. They inhabit deciduous or mixed woodlands with a high proportion of oak, shrubland with scattered trees, and hedgerows. These small birds are also common in parks, gardens, and even in the center of towns.


Eurasian blue tits are usually resident and non-migratory birds. They are social and often form mixed winter flocks with Great tits. These small birds are active during the day spending most of their time searching for food in trees, bushes, and sometimes on the ground. Blue tits are very active and agile when foraging; they will often ascend a trunk in short jerky hops, imitating a treecreeper, and can hang from almost anywhere. As a rule, they roost in ivy or evergreens, but in harsh winters will roost wherever there is a suitable small hole, be it in a tree or nesting box. Eurasian blue tits sing and call throughout the year. Songs are mostly used in late winter and spring to defend the territory or to attract mates. Calls are used for multiple reasons. The birds inform one another of their location in trees by means of contact-calls.
They use alarm-calls to warn others (including birds of other species) about the presence of predators in the neighborhood. Scolding, for example, is used when a ground predator (e.g. fox, cat, or dog), a low-flying predator, or a perched owl is noticed. Sometimes this is followed by mobbing behavior in which birds gather together in flocks to counter a predator. The alarm whistle warns other birds about the proximity of a Eurasian sparrowhawk, a northern goshawk, a common buzzard, or other flying predators that form a potential danger in the air.


Eurasian blue tits are polygynous meaning that males mate with more than one female. The breeding season takes place between April and late June. Courtship includes flights performed by the male and both partners then give a series of high-pitched 'zeedling' notes. Eurasian blue tits nest in any suitable hole in a tree, wall, or stump, or an artificial nest box, often competing with house sparrows or great tits for the site. The nest itself is a cup made with dried grasses, moss, leaves, wool, hair, and feathers. The female usually produces 2 broods per year laying 7-14 eggs in each clutch. Incubation lasts about 12 to 16 days and is performed by the female. The male feeds the female during this time. The chicks hatch altricial (helpless) and are fed by both parents. They usually spend 3 weeks in the nest before fledging.           

18-11-2017 HANNINGFIELD RESERVOIR, ESSEX - BRITISH GREAT TIT (Parus major ssp. newtoni)


The great tit (Parus major) is a small passerine bird, easily recognized by its black head and neck, striking white cheeks, olive upperparts, and vibrant yellow underparts. This bird is the most widespread species in the genus Parus, found across Europe, the Middle East, Central Asia, and parts of North Africa.

Males are characterized by their bright plumage, with a black bib that extends down the belly, bordered by a lemon-yellow breast. Females and juveniles are similar but have duller coloration. The black line down the belly is also narrower and sometimes broken in these birds.

Great tits favor a variety of woodland habitats, including deciduous and mixed forests, forest edges, and even urban parks and gardens. They are also found in riverine woodlands and, in some regions, boreal taiga.

This species is resident throughout its range, which extends from the Iberian Peninsula to the Amur Valley, and from Scandinavia to the Middle East. It is generally non-migratory, except in harsh winters when it may move to more temperate areas.

Great tits are known for their intelligence and adaptability. They exhibit a range of foraging behaviors and can solve problems with insight learning. They are also cavity nesters and are monogamous, with both parents involved in raising the chicks.


The great tit has a repertoire of up to 40 calls and songs, with the male being particularly vocal. A common call resembles the phrase "teacher, teacher," which is used to proclaim territory.

Breeding occurs once a year, with the female laying up to 12 eggs in a cavity nest. The female incubates the eggs alone, but both parents feed the chicks. In most years, the pair will raise two broods.

In summer, the diet is predominantly insectivorous, while in winter, it expands to include seeds and berries. Great tits are adept at handling large food items and are known to visit bird feeders in urban areas.

The great tit is classified as Least Concern by the IUCN, with a stable and widespread population estimated to be between 300 and 1,100 million birds. It has adapted well to human changes in the environment and is not currently at risk.

18-11-2017 BRENTWOOD, ESSEX - BRITISH BLUE TIT (Cyanistes caeruleus ssp. obscurus)


The blue tit is a delicate little bird, weighing in at around 11g – half the size of a robin. Often considered our most attractive garden bird, the blue tit is extremely colourful, with a bright blue cap, white face, black stripes across the eyes, bright yellow breast and blue, green and white wings.

18-11-2017 HANNINGFIELD RESERVOIR, ESSEX - REDWING (Turdus iliacus)


The redwing (Turdus iliacus) is a bird in the thrush family, Turdidae, native to Europe and the Palearctic, slightly smaller than the related song thrush.

It is 20–24 cm long with a wingspan of 33–34.5 cm and a weight of 50–75 g. The sexes are similar, with plain brown backs and with dark brown spots on the white underparts. The most striking identification features are the red flanks and underwing, and the creamy white stripe above the eye. Adults moult between June and September, which means that some start to replace their flight feathers while still feeding young.

It breeds in northern regions of Europe and the Palearctic, from Iceland south to northernmost Scotland, and east through Scandinavia, the Baltic States, northern Poland and Belarus, and through most of Russia to about 165°E in Chukotka Autonomous Okrug. In recent years it has expanded its range slightly, both in eastern Europe where it now breeds south into northern Ukraine, and in southern Greenland, where the Qaqortoq area was colonised in 1990–1991.

It is often replaced by the related ring ouzel in areas of higher altitude.

It is migratory, wintering in western, central and southern Europe, north-west Africa, and south-west Asia east to northern Iran. Birds in some parts of the west of the breeding range (particularly south-western Norway) may be resident, not migrating at all, while those in the far east of the range migrate at least 6,500–7,000 km to reach their wintering grounds.

16-11-2017 VILLALONGA RESERVOIR, VALENCIA - COMMON CHIFFCHAFF (Phylloscopus collybita)


The Common Chiffchaff, Phylloscopus collybita, is a diminutive and sprightly leaf warbler known for its distinctive, onomatopoeic song. This small, migratory passerine is characterized by its greenish-brown upperparts and off-white underparts, with a weight ranging from 6 to 8 grams and a length of 10-12 centimeters.

In the field, look for the Common Chiffchaff's short whitish supercilium, fine dark bill, and dark legs. Its primary projection is short, and the plumage may appear duller and browner as it wears. Juveniles are browner above with yellow-white underparts, but they soon acquire brighter plumage after their first moult.

The Common Chiffchaff breeds in open woodlands with a mix of taller trees and ground cover across northern and temperate Europe, Asia, and parts of north Africa. It prefers woodland with trees at least 5 meters high and an undergrowth of grasses and nettles.


This species has a vast breeding range, extending from Europe to eastern Siberia and northward to about 70 N. It winters in southern and western Europe, southern Asia, and north Africa. The Common Chiffchaff is one of the earliest spring migrants to return to its breeding grounds and one of the last to depart in autumn.

The male Common Chiffchaff is fiercely territorial during the breeding season, defending its core territory against rivals. It exhibits a fearless nature, even attacking predators that threaten its nest. Outside the breeding season, these birds may form small flocks with other warblers.


The song is a cheerful "chiff-chaff," which heralds the arrival of spring. Calls include a "hweet" sound, less disyllabic than the calls of closely related warblers. The song is a key distinguishing feature from similar species, such as the Iberian Chiffchaff.

The female constructs a domed nest on or near the ground, lined with feathers. Clutches typically consist of 2-7 cream-colored eggs, which hatch after 13-14 days. The female assumes most of the responsibility for brooding and feeding the chicks, with the male playing a minimal role.

The Willow Warbler and Bonelli's Warbler are similar species but can be differentiated by their longer primary projection, sleeker appearance, and different vocalizations. The Iberian Chiffchaff, once considered a subspecies, is now treated as a separate species due to differences in song, morphology, and genetics.


The Common Chiffchaff is insectivorous, feeding on a variety of insects and other small invertebrates. It is known to be an active forager, often seen flitting through foliage or hovering briefly to snatch prey.

The Common Chiffchaff is classified as "Least Concern" by the IUCN, with an extensive range and large population. While one subspecies is likely extinct, the overall species does not face significant threats at present, and populations in some areas are increasing.

16-11-2017 VILLALONGA RESERVOIR, VALENCIA - COMMON DARTER DRAGONFLY (MALE) (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.

15-11-2017 EL SALER, VALENCIA - DOMESTIC MUSCOVY DUCK (Cairina moschata var. domestica)


The Muscovy had been domesticated by various indigenous peoples of the Americas well before the arrival of Christopher Columbus in 1492.

Domestic Muscovy drakes weigh some 4.5–6.3 kg. The duck is much smaller, typically about half the size of the drake, with a weight of 2.3–3.2 kg.[3]: 466 

Recognised colour varieties include five solid colours – black, blue, chocolate, lavender and white[3]: 465  – and eight 'magpie' colours, in which the whole back from the tail to the shoulders and the underside from below the tail to the breast is coloured black, blue, chocolate or lavender, the remainder being white. In the standard magpie colourings the crown of the head is also coloured; in the white-headed magpie colours the head is white.

15-11-2017 RACO DE OLLA, VALENCIA - BLACK WINGED STILT (JUVENILE) (Himantopus himantopus)


The Black-winged Stilt, Himantopus himantopus, is a slender wader known for its strikingly long, pink legs and contrasting black-and-white plumage. This elegant bird is a member of the avocet and stilt family, Recurvirostridae.

Adult Black-winged Stilts measure 33–36 cm in length. They possess a long, thin black bill and display a distinctive black and white coloration. The head and neck are predominantly white, with variable black markings depending on the sex and subspecies. Males typically have a glossy or greenish sheen on their black backs, while females exhibit a more brownish tinge. During flight, their long legs trail behind, and their wingbeats are steady.


These birds favor marshes, shallow lakes, and ponds as their breeding grounds. They are also known to inhabit coastal areas during migration and in the winter months.

The Black-winged Stilt has a wide range, extending across Europe, Asia, and Africa. Some populations migrate to coastal regions in winter, while others in milder climates may remain resident or engage in short-range movements.


Black-winged Stilts are often seen foraging in shallow waters, gracefully picking insects and crustaceans from the surface. They are known to nest in small groups, sometimes alongside avocets, and exhibit a variety of courtship behaviors, including intricate displays and duets.

The flight call of the Black-winged Stilt is a sharp and clear kleek, typically heard during its aerial maneuvers.

Nests are simple bare spots on the ground near water. These birds are communal nesters and may breed in loose colonies. They have been known to breed as far north as Britain, with recent successful breeding events recorded in Southern and Northern England.


The Black-winged Stilt can be confused with other stilt species, such as the Black-necked Stilt (H. mexicanus) in the Americas, the White-backed Stilt (H. melanurus), and the Pied Stilt (H. leucocephalus) in Australasia and New Zealand.

Their diet consists mainly of insects and crustaceans, which they deftly pick from the water's surface or from wet sand.

The IUCN lists the Black-winged Stilt as Least Concern, indicating a stable global population. However, they are protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds, highlighting the importance of international cooperation in their conservation.

15-11-2017 EL SALER, VALENCIA - EUROPEAN ROBIN (Erithacus rubecula)


The European robin (Erithacus rubecula) is a small insectivorous passerine bird. The term robin is also applied to some birds in other families with red or orange breasts. These include the American robin (Turdus migratorius ), a thrush, and the Australasian robins of the family Petroicidae.
The male and female European robins are similar in coloration, with an orange breast and face lined with grey, brown upperparts, and a whitish belly. The bill and eyes are black. Juveniles are spotted brown and white in coloration, with patches of orange gradually appearing.

European robins occur in Eurasia east to Western Siberia, south to Algeria, and on the Atlantic islands as far west as the Central Group of the Azores and Madeira. Irish and British robins are largely resident but a small minority, usually female, migrate to southern Europe during winter, a few as far as Spain. Scandinavian and Russian robins migrate to Britain and western Europe to escape the harsher winters. European robins prefer spruce woods in northern Europe, contrasting with their preference for parks and gardens in Ireland and Great Britain. These may also be found in grasslands, shrubby vegetation, hedgerows with some tall trees, orchards, and farmlands.

15-11-2017 EL SALER, VALENCIA - EURASIAN KESTREL (Falco tinnunculus)


The common kestrel, Falco tinnunculus, is a bird of prey from the kestrel group within the falcon family Falconidae. It is also known as the European kestrel, Eurasian kestrel, or Old World kestrel. In the United Kingdom, it is often simply referred to as the "kestrel." This raptor is small compared to other birds of prey but larger than most songbirds, with long wings and a distinctive long tail.

Males and females exhibit sexual dimorphism in their plumage. The male has a blue-grey cap and tail with a black tip bordered by a narrow white rim. Its back is chestnut with black spots, and the underside is buff with black streaks. The female is larger and lacks the blue-grey coloring, having a brown back with black bars and a similar underside to the male. Both sexes have a prominent black malar stripe, bright yellow cere, feet, and eye-ring, with dark toenails, bill, and iris.

The common kestrel favors open habitats such as fields, heaths, shrubland, and marshland. It does not require woodland but needs alternative perching and nesting sites like rocks or buildings. It thrives in treeless steppes and can adapt to human settlements and various landscapes, from wetlands to arid savannas.

15-11-2017 EL SALER, 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.


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.

15-11-2017 EL SALER, VALENCIA - WESTERN CATTLE EGRET (Bubulcus ibis ssp. ibis)


The Cattle Egret, a member of the heron family Ardeidae, is a small white bird recognized for its association with grazing animals. It exhibits a stout build, with a wingspan ranging from 88 to 96 cm, and a body length between 46 to 56 cm. The species is relatively light, weighing between 270 to 512 grams. It is characterized by a short, thick neck, a robust bill, and a somewhat hunched posture.

Outside the breeding season, the adult Cattle Egret has predominantly white plumage, a yellow bill, and greyish-yellow legs. Come breeding time, the western variety develops striking orange-buff plumes on the back, breast, and crown, while the bill, legs, and irises turn a vivid red. The eastern variety differs slightly with buff coloration extending to the cheeks and throat during breeding, and the plumes taking on a more golden hue. Both sexes are similar in appearance, though males are marginally larger with longer breeding plumes.

Cattle Egrets are adaptable birds that exploit a variety of drier and open habitats more than other heron species. Their preferred environments include seasonally inundated grasslands, pastures, farmlands, wetlands, and rice paddies.

Originally native to parts of Asia, Africa, and Europe, the Cattle Egret has seen a significant expansion in its distribution, colonizing much of the rest of the world over the last century. It is now found in the tropics, subtropics, and warm-temperate zones globally.

15-11-2017 EL SALER, VALENCIA - SMALL WHITE BUTTERFLY (Pieris rapae)


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

The caterpillar of this species, often referred to as the "imported cabbageworm", is a pest to crucifer crops such as cabbage, kale, bok choy and broccoli. Pieris rapae is widespread in Europe and Asia; it is believed to have originated in the Eastern Mediterranean region of Europe, and to have spread across Eurasia thanks to the diversification of brassicaceous crops and the development of human trade routes. Over the past two centuries, it spread to North Africa (about 1800), North America (1860s), Hawaii (1897), New Zealand (1930), and Australia (1937), as a result of accidental introductions.

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

Pieris rapae has a wingbeat frequency averaging 12.8 flaps per second.


The species has a natural range across Europe, Asia, and North Africa. It was accidentally introduced to Quebec, Canada, around 1860 and spread rapidly throughout North America. The species has spread to all North American life zones from Lower Austral/Lower Sonoran to Canada. Estimates show that a single female of this species might be the progenitor in a few generations of millions. It is absent or scarce in desert and semidesert regions (except for irrigated areas). It is not found north of Canadian life zone, nor on Channel Islands off the coast of southern California. By 1898, the small white had spread to Hawaii; by 1929, it had reached New Zealand and the area around Melbourne, Australia, and found its way to Perth as early as 1943. It does not seem to have made it to South America.

In Britain, it has two flight periods, April–May and July–August, but is continuously brooded in North America, being one of the first butterflies to emerge from the chrysalis in the spring and flying until hard freeze in the fall.

The species can be found in any open area with diverse plant association. It can be seen usually in towns, but also in natural habitats, mostly in valley bottoms. Although an affinity towards open areas is shown, the small white is found to have entered even small forest clearings in recent years.

The nominate subspecies P. r. rapae is found in Europe, while Asian populations are placed in the subspecies P. r. crucivora. Other subspecies include atomaria, eumorpha, leucosoma, mauretanica, napi, novangliae, and orientalis.

15-11-2017 EL SALER, VALENCIA - BLACK REDSTART (FEMALE) (Phoenicurus ochruros)


The Black redstart (Phoenicurus ochruros) is a small passerine bird in the genus Phoenicurus. Like its relatives, it was formerly classed as a member of the thrush family (Turdidae), but is now known to be an Old World flycatcher (Muscicapidae).

The adult male of this species is overall dark grey to black on the upperparts and with a black breast; the lower rump and tail are orange-red, with the two central tail feathers dark red-brown. The belly and undertail are either blackish-grey (western subspecies) or orange-red (eastern subspecies); the wings are blackish-grey with pale fringes on the secondaries forming a whitish panel (western subspecies) or all blackish (eastern subspecies). The female is grey (western subspecies) to grey-brown (eastern subspecies) overall except for the orange-red lower rump and tail, greyer than the common redstart; at any age, the grey axillaries and underwing coverts are also distinctive. There are two distinct forms in first calendar year males at least in western subspecies, with the first ('carei') being similar to females and the second ('paradoxus') approaching adult males but lacking the whitish wing panel that does only develop during post-breeding molt of wing feathers in the second calendar year. This second form is much rarer than the first.


 Black redstarts breed in south and central Europe and Asia and north-west Africa, from Great Britain and Ireland (where local) south to Morocco, east to central China. They are resident in the milder parts of their range, but north-eastern birds migrate to winter in southern and western Europe and Asia, and north Africa. In some areas, birds that breed in mountains move to lower elevations in winter. Black redstarts inhabit stony ground in mountains, particularly cliffs and stony slopes with xerophytic vegetation. They are also found in villages, and urban areas and often occur in large industrial complexes that have bare areas and cliff-like buildings.

15-11-2017 EL SALER, VALENCIA - BLACK HEADED GULL (Chroicocephalus ridibundus)


The black-headed gull (Chroicocephalus ridibundus) is a small, nimble gull with a wingspan ranging from 94 to 110 cm and a body length of 37 to 44 cm. It weighs between 190 and 400 grams. Despite its name, the adult's summer plumage features a chocolate-brown head, which can appear black from a distance. The body is pale grey, and the primary wing feathers are tipped with black. The bill and legs are a striking red. In winter, the brown head is replaced by a white one with dark spots. Juveniles are mottled with brown spots and have a black band on the tail. There is no sexual dimorphism in plumage.

In flight, the white leading edge of the wing is a distinctive field mark. The summer adult's brown head, red bill, and legs are key identifiers, while the winter plumage features two dark spots on the head. Juveniles can be recognized by their mottled brown pattern and black tail band.

This species nests in colonies on the ground in large reed beds, marshes, or islands within lakes. It is not pelagic and is seldom seen far from coasts.

The black-headed gull breeds across much of the Palearctic, including Europe and coastal eastern Canada. It is migratory, wintering further south, but some remain in the milder westernmost areas of Europe. It is also present in northeastern North America and occasionally seen as far south as Virginia and some Caribbean islands.

Highly gregarious in winter, the black-headed gull is an opportunistic feeder, consuming a wide range of food from insects to carrion. It is known for its "kree-ar" call and displays various behaviors such as eggshell removal from the nest, which is believed to reduce predation risk.

14-11-2017 ADOR CAMPO, VALENCIA - LITTLE OWL (Athene noctua)


The Little Owl, Athene noctua, is a diminutive yet distinctive bird, often associated with the goddess Athena in Greek mythology and Minerva in Roman lore. This bird is characterized by a flat-topped head, a robust, compact body, and a relatively short tail. Its plumage is a mottled greyish-brown, adorned with white spots, streaks, and bars, giving it a cryptic appearance. Both sexes are similar in size, measuring approximately 22 cm in length with a wingspan of 56 cm, and weighing around 180 grams.

The Little Owl possesses a large head, elongated legs, and striking yellow eyes. Its white "eyebrows" lend it a somewhat stern expression. Juvenile birds are somewhat duller than adults and lack the white crown spots. The species is known for its woodpecker-like bounding flight. During the moult, which occurs from July to November, males begin shedding feathers before females.


This owl favors open countryside and thrives in a variety of habitats, including agricultural lands with hedgerows and trees, orchards, woodland edges, parks, gardens, steppes, and semi-deserts. It can also be found in treeless areas such as dunes, and near human-made structures like ruins and quarries.

The Little Owl's range spans much of temperate and warmer parts of Europe, the Palearctic east to Korea, and North Africa. It has been introduced to Britain and the South Island of New Zealand, where it has established populations.

The Little Owl is known for its territorial nature, with males defending their territories from intruders. It is partly diurnal and can often be seen perched in prominent positions during the day. Its diet consists of insects, earthworms, other invertebrates, and small vertebrates. The owl is adept at swooping down on prey from its perch and is known to cache surplus food.


The Little Owl's call is a querulous "kiew, kiew," and it also produces various whistling or trilling sounds. During the breeding season, it may emit more modulated calls, and pairs can engage in duets. Near the nest, the owl may make yelping, chattering, or barking noises.

Breeding season sees increased vocal activity at night in late spring. Nests are located in a variety of places, including tree holes, cliffs, and old buildings. The female lays a clutch of about four eggs, which she incubates. The male provides food during this period, and both parents feed the chicks once hatched. Young owls fledge at about seven weeks of age.

The Little Owl can be confused with other small owl species, but its distinctive "eyebrows," yellow eyes, and flight pattern help differentiate it.

The Little Owl's diet is diverse, including mammals like mice and voles, birds, and a wide range of insects. It hunts both on the ground and in flight, and food caching behavior has been observed.

14-11-2017 MONTE CORONA, VALENCIA - HORSE CHESTNUT MOTH (Pachycnemia hippocastanaria)


Pachycnemia hippocastanaria, the horse chestnut moth, is a moth of the family Geometridae. It is found in most of Europe.

The wingspan is 28–32 mm. Adults are on wing from April to May, and again in a partial second generation in August, usually with fewer and smaller moths.


A distinctly southern species in Britain, occurring only on the heaths of the southernmost counties, although in places can be fairly common.

The moths fly in April and May, with a second brood in August, usually with fewer and smaller moths, although in some parts of the country, the autumn brood now appears to produce more records.

Both the English and Latin names refer to the horse chestnut, but the origins of these are unknown, as the larval foodplant is heather (Calluna).
