30-12-2020 MUNTANYETA DEL SANTS, VALENCIA - NORTHERN LAPWING (Vanellus vanellus)
%2020.jpg)
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.
Its diet consists primarily of insects and other small invertebrates. The Northern Lapwing often feeds in mixed flocks with Golden Plovers and Black-headed Gulls, the latter of which may steal food but also offer some protection against predators.

%2022.jpg)
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.
Breeding takes place on the ground in a simple scrape. The species typically lays 3–4 eggs, which are zealously defended against all intruders. The Northern Lapwing's breeding strategy includes feigning injury to distract predators from its nest.
30-12-2020 CREU DE LONGA, VALENCIA - MEADOW PIPIT (Anthus pratensis)
The Meadow Pipit, Anthus pratensis, is a small, unassuming bird of the passerine family. It measures between 14.5 to 15 cm in length and weighs a mere 15 to 22 grams. Its plumage is predominantly brown above and buff below, with darker streaks adorning most of its body. The tail is brown with narrow white edges, and it stands on pale pinkish-yellow legs. A distinctive feature is its notably long hind claw, surpassing the length of its other hind toes.
When identifying the Meadow Pipit, look for its streaked appearance and listen for its weak "tsi-tsi" call. In flight, observe its song, which is a simple, repetitive tune that increases in pace towards the end. The bird's small size and long hind claw are also key identification markers.
The Meadow Pipit favors open spaces such as pastures, bogs, and moorlands. It can also be found in low-intensity agricultural areas and, during winter, in saltmarshes and occasionally open woodlands.
This species breeds across the Palearctic, from Greenland and Iceland to the Ural Mountains, and south to central France and Romania. An isolated population resides in the Caucasus Mountains. While migratory over most of its range, wintering in southern Europe, North Africa, and southwestern Asia, it remains resident year-round in western Europe.
The Meadow Pipit is a terrestrial bird, feeding on the ground and using elevated perches to scan for predators. It is known to move to the coast or lowlands during winter, even in areas where it is considered resident.
The call of the Meadow Pipit is a soft "tsi-tsi." Its song, delivered during a short song flight, is a simple melody that quickens as it progresses.
Nests are well-concealed on the ground in dense vegetation. Clutches typically contain two to seven eggs, which hatch after 11 to 15 days. Fledging occurs 10 to 14 days post-hatching, and the species often raises two broods per year. The Meadow Pipit is a frequent host for the cuckoo's parasitic breeding strategy.
Its diet consists mainly of insects and other invertebrates, favoring prey less than 5 mm in length. During winter, it also consumes seeds from grasses, sedges, rushes, heather, and crowberry berries.
The Meadow Pipit is classified as Least Concern by the IUCN. However, there has been a noted decline in populations, particularly in French farmland, where numbers have dropped by 68% over the past 17 years.
The meadow pipit (Anthus pratensis) is a small passerine bird that breeds throughout much of the Palearctic, from south-eastern Greenland and Iceland east to just east of the Ural Mountains in Russia, and south to central France and Romania; an isolated population also occurs in the Caucasus Mountains. It is migratory over most of its range, wintering in southern Europe, North Africa, and south-western Asia, but is resident year-round in western Europe, although even here many birds move to the coast or lowlands in winter.
It is primarily a species of open habitats, either uncultivated or low-intensity agriculture, such as grassland, moorland, and heathland, but also occurs in small numbers on arable land. In winter, it also uses saltmarshes and sometimes open woodland. It is a fairly terrestrial pipit, always feeding on the ground, but using elevated perches such as shrubs, fence lines, or electric wires as vantage points to watch for predators.

The White Wagtail is commonly found in open country, often in close proximity to human habitation and water sources. It shows a preference for bare areas which facilitate the sighting and pursuit of prey. This bird has adapted well to urban environments, utilizing paved areas such as parking lots for foraging.
This species has a vast breeding range across Europe, the Asian Palearctic, parts of North Africa, and has a presence in Alaska. It is a migratory bird, with populations moving to Africa and parts of Asia during the winter. In Great Britain and Ireland, the darker subspecies known as the Pied Wagtail is more prevalent.
The White Wagtail is known for its perpetual tail wagging, a behavior that remains somewhat enigmatic but is thought to be a signal of vigilance to predators. It is a monogamous bird that defends its breeding territory with determination.
The call of the White Wagtail is a sharp "chisick," softer than that of the Pied Wagtail. Its song is more structured and is used by males to attract females rather than to mark territory.
30-12-2020 CREU DE LONGA, VALENCIA - GLOSSY IBIS (Plegadis falcinellus)
The Glossy Ibis, Plegadis falcinellus, is a wading bird of the family Threskiornithidae, known for its striking, sickle-shaped bill. This mid-sized ibis measures 48–66 cm in length, with a wingspan of 80–105 cm. Breeding adults boast reddish-brown bodies and iridescent bottle-green wings, while non-breeders and juveniles display a more subdued coloration. The species is characterized by a brownish bill, dark facial skin with blue-gray to cobalt blue borders, and red-brown legs. In flight, the ibis extends its neck and exhibits a graceful V formation.
When identifying the Glossy Ibis, look for its unique glossy feathers and the distinct shape of its bill. The bird's flight pattern is also a telltale sign, as it flies with its neck outstretched, unlike herons. Listen for its various croaks and grunts, particularly the hoarse grrrr sound during the breeding season.
The Glossy Ibis favors freshwater or brackish wetlands with tall, dense emergent vegetation such as reeds, papyrus, or rushes, and low trees or bushes. It can also be found in lagoons, floodplains, wet meadows, swamps, reservoirs, sewage ponds, rice paddies, and irrigated farmland. Coastal habitats like estuaries and salt marshes are less common for this species.
This ibis is the most widespread of its kind, breeding in warm regions across Europe, Asia, Africa, Australia, and the Americas. It is migratory, with European birds wintering in Africa and North American birds migrating southward. The species has been expanding its range, with increasing numbers in Europe and successful breeding in Britain as of 2022.
The Glossy Ibis is known for its nomadic tendencies and dispersal movements post-breeding. Northern populations are migratory, traversing vast distances such as the Sahara Desert. The species nests in mixed colonies and forms large flocks during migration and winter. It often roosts communally with other species, sometimes in trees far from feeding areas.
The Glossy Ibis is relatively quiet, but it does produce a range of vocalizations, including croaks and grunts. A distinctive hoarse grrrr can be heard during the breeding season.
Nesting occurs above water on platforms of twigs and vegetation, with both parents incubating the 3 to 4 eggs laid. Chicks leave the nest after about a week but are fed by parents for another 6 to 7 weeks, fledging around 28 days old.
The ibis's diet is seasonal and opportunistic, feeding on a variety of prey such as insects, annelids, molluscs, crustaceans, and occasionally fish, amphibians, lizards, small snakes, and nestling birds.
The Glossy Ibis is classified as Least Concern by the IUCN. However, it faces threats from habitat degradation and loss due to drainage, salinity changes, groundwater extraction, and invasive plant species. It is protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA).

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.
The black-headed gull is a vocal species, particularly in colonies. Its call is a familiar "kree-ar," and its scientific name suggests a laughing sound.

27-12-2020 SOLLANA, 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.
27-12-2020 ULLAL DE BALDOVI, VALENCIA - LESSER BLACK BACKED GULL (JUVENILE) (Larus fuscus)
%20(Larus%20fuscus)%20%2020.jpg)
Adult lesser black-backed gulls have yellow legs and a yellow bill with a red spot. Their wings and back are either black or dark grey, depending on the subspecies. In winter, the head becomes greyer. Juveniles display scaly black-brown upperparts and a distinctive wing pattern. They can be differentiated from juvenile herring gulls by their darker, unbarred tertial feathers.
This species is found along coasts and lakes, where it breeds and feeds. It has adapted to urban environments in some cities, nesting alongside herring gulls.
The lesser black-backed gull breeds on the Atlantic coasts of Europe and is migratory, wintering from the British Isles to West Africa. It has expanded its range to North America, particularly along the east coast, where it is now present year-round in increasing numbers.
These gulls are social birds, breeding colonially. They exhibit a fixed action pattern during feeding, where the young peck at the red spot on the adult's bill to induce regurgitation.
27-12-2020 SOLLANA, VALENCIA - EUROPEAN STARLING (Sturnus vulgaris)
The Common Starling, Sturnus vulgaris, is a medium-sized passerine bird characterized by its glossy black plumage with a metallic sheen. Throughout the year, the plumage is speckled with white, though less so during the breeding season. Adults measure approximately 20 cm in length, with pink legs and a seasonally changing bill color—black in winter and yellow in summer. Juveniles display browner plumage compared to adults.
arling, look for its iridescent black feathers, which may appear purple or green when reflecting light. The bird's bill is black in the winter and transitions to yellow in the summer, aiding in identification. The starling's flight is strong and direct, with pointed wings that are distinctive in the air. On the ground, its waddling gait is notable.
Common Starlings are highly adaptable, favoring urban and suburban areas where they find ample nesting and roosting opportunities. They also inhabit grasslands, such as farmlands and pastures, where short grass makes foraging for invertebrates easier.
Native to temperate Europe and western Asia, the Common Starling has been introduced to Australia, New Zealand, North America, and other regions. Its range extends from Europe to northern Africa and across the Palearctic to western Mongolia.
The Common Starling is a gregarious bird, especially in autumn and winter, forming large flocks known as murmurations. These flocks are thought to be a defense against predators. On the ground, starlings forage in groups, often following grazing animals to feed on disturbed invertebrates.
The Common Starling's song is a varied mix of melodic and mechanical sounds, including mimicked noises from other bird species and the environment. Males sing to attract mates and defend their territory. Calls include a harsh alarm scream and a variety of social chatters.
Breeding occurs in the spring and summer, with the female laying four to five glossy, pale blue eggs in a nest built within a natural or artificial cavity. Both parents share incubation duties, and the young fledge after about three weeks.
The Spotless Starling is similar in appearance but can be distinguished by its lack of iridescent spots in adult breeding plumage and longer throat feathers.
Omnivorous, the Common Starling's diet includes a wide range of invertebrates, seeds, and fruit. They employ various foraging techniques, such as probing the ground and catching flying insects.
27-12-2020 MUNTANYETA DEL SANTS, VALENCIA - COMMON CHAFFINCH (FEMALE) (Fringilla coelebs)
%20(Fringilla%20coelebs)%2021.jpg)
The Eurasian chaffinch, or simply the chaffinch (Fringilla coelebs), presents a striking dichotomy in plumage between the sexes. The male is resplendent with a blue-grey cap and rust-red underparts, while the female's attire is more subdued, though both genders boast two white wing bars and white sides to their tails. The male's robust voice is a herald of spring, as he sings from exposed perches to court a mate.
To identify the male chaffinch, look for the black forehead, blue-grey crown, and rust-red breast, which fades to a pale creamy-pink on the belly. The wings feature a white panel on the coverts and a buff-white bar on the secondaries and inner primaries. Females and juveniles are more muted with grey-brown shades above and paler below, but retain the distinctive wing markings.
Chaffinches favor wooded environments, thriving in areas where the July isotherm ranges from 12 to 30°C. They are adaptable, however, and can be found in a variety of forested landscapes across their range.
This small passerine bird is widespread across Europe and parts of Asia, extending to Siberia. It is also an introduced species in some regions, such as New Zealand and South Africa.
%20(Fringilla%20coelebs)%2022.jpg)
Chaffinches are gregarious outside the breeding season, forming flocks in open countryside. They exhibit partial migration, with birds in colder regions moving south for the winter, while those in milder areas may remain sedentary.
The male chaffinch's song is a delightful mix of trills and chirps, with regional dialects adding to the chorus. Each male typically has a repertoire of two or three song types.
Monogamous by nature, chaffinches breed once they reach one year of age. The female meticulously constructs a nest in the fork of a tree, laying a clutch of 4-5 eggs that hatch in about 13 days. The fledglings take to the wing approximately 14 days later but continue to receive parental care for several weeks thereafter.
During the breeding season, chaffinches forage in trees for invertebrates, particularly caterpillars, to feed their young. Outside this period, their diet shifts to seeds and plant material found on the ground.
Chaffinches must be vigilant against a variety of predators, including crows and squirrels, which may prey upon their eggs and nestlings. They are also susceptible to parasites such as the protozoal Trichomonas gallinae and the Fringilla coelebs papillomavirus, which can cause tumors on their feet and legs.
