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).

13-11-2017 JALON, ALICANTE - 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.

12-11-2017 VILLALONGA RESERVOIR, VALENCIA - WHITE WAGTAIL (Motacilla alba)


12-11-2017 VILLALONGA RESERVOIR, VALENCIA - EURASIAN GREAT CORMORANT (Phalacrocorax carbo)



12-11-2017 PEGO MARJAL, ALICANTE - WATER PIPIT (Anthus spinoletta)



12-11-2017 PEGO MARJAL, 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.

9-11-2017 OLIVA MARJAL, VALENCIA - COMMON CHIFFCHAFF (Fringilla coelebs)


9-11-2017 BONAIRE, VALENCIA - EURASIAN TREE SPARROW (FEMALE) (Passer montanus)


The house sparrow (Passer domesticus) is a member of the sparrow family Passeridae. This small bird typically measures around 16 cm (6.3 in) in length and weighs between 24–39.5 g (0.85–1.39 oz). The species exhibits sexual dimorphism, with females and young birds displaying pale brown and grey plumage, while males are characterized by more vibrant black, white, and brown markings.

Males can be identified by their bright black, white, and brown markings, with a distinctive black bib, white cheeks, and a grey crown. Females lack the striking head patterns of males and are predominantly buffish with softer coloration. Juveniles resemble adult females but are generally paler with less defined markings.


The house sparrow is highly adaptable and can thrive in both urban and rural environments. It is commonly found in close association with human habitation and avoids dense forests, grasslands, polar regions, and deserts far from human development.

Native to Europe, the Mediterranean Basin, and much of Asia, the house sparrow has been introduced to various regions worldwide, including parts of Australasia, Africa, and the Americas, making it one of the most widely distributed wild birds.

House sparrows are social birds, often seen in flocks. They exhibit a range of behaviors, including dust or water bathing and communal roosting. Males are known to be territorial around their nesting sites.

The house sparrow's vocalizations are predominantly variations of a simple chirping call. Males may sing or give an "ecstatic call" during the breeding season, and the species uses a variety of calls for different social interactions.

House sparrows are generally monogamous and may mate for life. They can breed in the season following their hatching and often produce multiple clutches per year, with each clutch containing up to five eggs. Nest sites are varied, with a preference for cavities.

9-11-2017 CANAL LES FONTS OLIVA, VALENCIA - MALLARD (MALE) (Anas platyrhynchos)


The mallard or wild duck (Anas platyrhynchos) is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa, and 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.  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 mallard is widely distributed across the Northern and Southern Hemispheres; in North America its range extends from southern and central Alaska to Mexico, the Hawaiian Islands, across the Palearctic, from Iceland and southern Greenland and parts of Morocco (North Africa) in the west, Scandinavia and Britain to the north, and to Siberia, Japan, and South Korea. Also in the east, it ranges to south-eastern and south-western Australia and New Zealand in the Southern hemisphere It is strongly migratory in the northern parts of its breeding range, and winters farther south.


The mallard inhabits a wide range of habitats and climates, from the Arctic tundra to subtropical regions. It is found in both fresh- and salt-water wetlands, including parks, small ponds, rivers, lakes and estuaries, as well as shallow inlets and open sea within sight of the coastline. Water depths of less than 0.9 metres (3.0 ft) are preferred, with birds avoiding areas more than a few metres deep. They are attracted to bodies of water with aquatic vegetation.

9-11-2017 CAMI LES FONTS OLIVA, VALENCIA - MALLARD (FEMALE) (Anas platyrhynchos)


The female is only brown and white. She is smaller than the male and has straight tail feathers. Body Length: 20-28 inches. Wing tip to wing tip: 30-40 inches.

Females and juveniles are mottled brown with orange-and-brown bills. Both sexes have a white-bordered, blue “speculum” patch in the wing. Mallards are “dabbling ducks”—they feed in the water by tipping forward and grazing on underwater plants. They almost never dive.

Unlike some waterfowl, like Mute Swans, which stay together year in and year out, Mallards only hook up for a single season. For them it’s one and done. Each fall Mallards get together in large flocks and begin the process of selecting a new mate for the following spring. They perform an assortment of wild courtship displays until pairs are formed. Once paired off the new couple has their own mating rituals, and one of these is called the “inciting” display. Here the female follows the male around, no matter where he goes. It sometimes looks as if he’s trying to get away from her and I understand why because she is yapping in his ear the entire time. This is unique because most other females save their nagging until after the wedding. And no bird can nag better than Mrs. Mallard. Her voice is the quintessential duck call. Any TV show, kid’s toy or cartoon that needs a duck call uses the voice of a female Mallard. The classic, loud “quack, quack, quack” is exclusively hers. The male’s voice, conversely, is softer and less harsh. His quiet quack has an up-note at the end, almost like he’s asking a question (probably, “Is she ever going to shut up?”).

18-11-2017 HANNINGFIELD RESERVOIR, ESSEX - ROOK (Corvus frugilegus)


The rook (Corvus frugilegus) is a member of the family Corvidae in the passerine order of birds. It is found in the Palearctic, its range extending from Scandinavia and western Europe to eastern Siberia. It is a large, gregarious, black-feathered bird, distinguished from similar species by the whitish featherless area on the face. Rooks nest collectively in the tops of tall trees, often close to farms or villages, the groups of nests being known as rookeries.

Rooks are mainly resident birds, but the northernmost populations may migrate southwards to avoid the harshest winter conditions. The birds form flocks in winter, often in the company of other Corvus species or jackdaws. They return to their rookeries and breeding takes place in spring. They forage on arable land and pasture, probing the ground with their strong bills and feeding largely on grubs and soil-based invertebrates, but also consuming cereals and other plant material. Historically, farmers have accused the birds of damaging their crops, and have made efforts to drive them away or kill them. Like other corvids, they are intelligent birds with complex behavioural traits and an ability to solve simple problems.

8-11-2017 ULLAL DE BOLDOVI, VALENCIA - EURASIAN KESTREL (Falco tinnunculus)


The Common kestrel (Falco tinnunculus) is a bird of prey species that belongs to the falcon family Falconidae. This species occurs over a large range and in Britain, where no other kestrel species commonly occurs, it is generally just called "kestrel".

Common kestrels are small compared with other raptors, but larger than most songbirds. They are mainly light chestnut brown in color with blackish spots on the upperside and buff with narrow blackish streaks on the underside; the remiges are also blackish. The males have fewer black spots and streaks and their cap and tail are blue-grey. The tail is brown with black bars in females and has a black tip with a narrow white rim in both sexes. All Common kestrels have a prominent black malar stripe like their closest relatives. The cere, feet, and a narrow ring around the eye are bright yellow; the toenails, bill, and iris are dark. Juveniles look like adult females, but the underside streaks are wider; the yellow of their bare parts is paler.

Common kestrels are found in Europe, Asia, and Africa. These birds are sedentary but in the cold parts of their range, they migrate south in winter. Common kestrels live in open habitats such as tundra, taiga, grassland, shrubland, marshland, fields, and heaths. They can also be found in forested areas and readily adapt to human settlement, as long as sufficient swathes of vegetation are available. They also occur in wetlands, moorlands, arid savanna, and from the sea to the lower mountain range.


Common kestrels are usually seen alone but sometimes may travel in small flocks and nest in loose colonies. These birds hunt by day hovering about 10-20 m (35-65 ft) above the ground, searching for prey, either by flying into the wind or by soaring using ridge lift. Like most birds of prey, Common kestrels have keen eyesight enabling them to spot small prey from a distance. Once prey is sighted, the bird makes a short, steep dive toward the target. They often hunt along the sides of roads and motorways. Another favorite (but less conspicuous) hunting technique is to perch a bit above the ground cover, surveying the area. When the bird spots prey animals moving by, it will pounce on them. They also prowl a patch of hunting ground in a ground-hugging flight, ambushing prey as they happen across it. Common kestrels communicate with each other using various calls. When alarmed they utter 'kii-kii-kiikii' and in flight, the birds produce a 'kik-kik' call.

Common kestrels are monogamous and form long-lasting pair bonds. They start breeding in April or May in temperate Eurasia and between August and December in the tropics and southern Africa. Common kestrels nest in cavities, preferring holes in cliffs, trees, or buildings; in built-up areas, the birds will often nest on buildings and will reuse the old nests of other birds. Common kestrels are usually solitary nesters but may sometimes nest in loose colonies. The female lays a clutch of 3 to 7 eggs. Incubation lasts around 4 weeks, and only the female incubates the eggs. The male is responsible for providing her with food, and for some time after hatching this remains the same. Later, both parents share brooding and hunting duties until the young fledge, after 4-5 weeks. The family stays close together for a few weeks, during which time the young learn how to fend for themselves and hunt prey. They become reproductively mature and are ready to breed for the first time by the next breeding season.



In the mid-20th century populations of Common kestrels declined due to heavy use of organochlorine and other pesticides. At present, these birds of prey are not considered globally threatened, however, in some areas, they still suffer from pesticides as well as from habitat degradation and decline of their primary small mammal prey.

According to the IUCN Red List, the total population size of the Common kestrel is around 4,300,000-6,700,000 mature individuals. The European population consists of 411,000-631,000 pairs, which equates to 823,000-1,270,000 mature individuals Currently, this species is classified as Least Concern (LC) on the IUCN Red List but its numbers today are decreasing.

8-11-2017 TANCAT DE PIPA, VALENCIA - EURASIAN GREAT CORMORANT (Phalacrocorax carbo)


8-11-2017 TANCAT DE PIPA, VALENCIA - BOOTED EAGLE (Hieraaetus pennatus)


The booted eagle, Hieraaetus pennatus, is a medium-sized bird of prey, with a stature comparable to the common buzzard. It exhibits sexual dimorphism, with females being larger, weighing approximately 840–1,025 grams, while males are lighter at 510–770 grams. The species measures around 40 cm in length and boasts a wingspan ranging from 110 to 132 cm. It is characterized by two distinct plumage morphs: a pale variant with light grey feathers and a darker head and flight feathers, and a darker morph with mid-brown plumage and dark grey flight feathers.

When identifying the booted eagle, look for the white markings on the wings, often referred to as "landing lights," which are visible when the bird is in flight. The pale morph is dominant, but the darker morph can be more prevalent in certain eastern populations. The call of the booted eagle is a distinctive shrill "kli-kli-kli."

The booted eagle favors wooded, often hilly landscapes with some open areas. It breeds in rocky, broken terrain but is adaptable during migration, utilizing a variety of habitats except dense forests.

This raptor has a wide distribution, breeding in southern Europe, North Africa, and across Asia, with a disjunct breeding population in southwestern Africa. Northern populations are migratory, wintering in Sub-Saharan Africa and South Asia, while the southern African populations are sedentary.

8-11-2017 MUNTANYETA DEL SANS, VALENCIA - EUROPEAN STARLING (Sturnus vulgaris)


The Common starling (Sturnus vulgaris) is a medium-sized passerine bird in the starling family, Sturnidae. It is a noisy bird, especially in communal roosts and other gregarious situations, with an unmusical but varied song. Its gift for mimicry has been noted in literature including the Mabinogion and the works of Pliny the Elder and William Shakespeare.

The Сommon starling is a medium-sized bird. It has glossy black plumage with a metallic sheen, which is speckled with white at some times of the year. The legs are pink and the bill is black in winter and yellow in summer. Juveniles are grey-brown and by their first winter resemble adults though often retaining some brown juvenile feathering, especially on the head. They can usually be sexed by the color of the irises, rich brown in males, mouse-brown, or grey in females.

Common starlings are native to Eurasia and are found throughout Europe, northern Africa (from Morocco to Egypt), India (mainly in the north but regularly extending further south and extending into the Maldives) Nepal, the Middle East including Syria, Iran, and Iraq and north-western China. Common starlings in the south and west of Europe are mainly resident, although other populations migrate from regions where the winter is harsh. Most birds from northern Europe, Russia, and Ukraine migrate southwestwards or southeastwards. 


In the autumn, when immigrants are arriving from eastern Europe, many of Britain's common starlings are setting off for Iberia and North Africa. Common starlings prefer urban or suburban areas, reedbeds, grassy areas such as farmland, grazing pastures, playing fields, golf courses, and airfields where short grass makes foraging easy. They occasionally inhabit open forests and woodlands and are sometimes found in shrubby areas. These birds are also found in coastal areas, where they nest and roost on cliffs and forage amongst the seaweed.

Common starlings are highly gregarious birds, especially in autumn and winter when huge, noisy flocks may form near roosts. These birds move by walking or running, rather than hopping. Their flight is quite strong and direct; their triangular-shaped wings beat very rapidly, and periodically the birds glide for a short way without losing much height before resuming powered flight. When in a flock, starlings take off almost simultaneously, wheel and turn in unison, form a compact mass, or trail off into a wispy stream, bunch up again, and land in a coordinated fashion. Common starlings feed by day using three types of foraging behavior. "Probing" involves the bird plunging its beak into the ground randomly and repetitively until an insect has been found. "Hawking" is the capture of flying insects directly from the air, and "lunging" is the less common technique of striking forward to catch a moving invertebrate on the ground. Earthworms are caught by pulling from the soil. Common starlings communicate with help of various calls that include a flock call, threat call, attack call, snarl call, and copulation calls. The alarm call is a harsh scream, and while foraging together Common starlings squabble incessantly. They chatter while roosting and bathing, making a great deal of noise that can cause irritation to people living nearby. Their song consists of a wide variety of both melodic and mechanical-sounding noises as part of a ritual succession of sounds. The songsters are more commonly male although females also sing on occasion.
