24-11-2020 MARJALES DE INTERIOR, ALBUFERA - 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.
Cattle Egrets are often seen in the company of cattle or other large mammals, benefiting from the insects and small vertebrates these animals disturb. They are known for their migratory behavior, with some populations moving seasonally, while others disperse post-breeding.
At breeding colonies, the Cattle Egret emits a soft, guttural "rick-rack" call but is generally quiet outside this setting.
Breeding occurs in colonies, often near water and in the company of other wading birds. The nest is a platform of sticks in trees or shrubs. Both parents are involved in nest construction and incubation, which lasts about 23 days. Chicks are born with some down and are dependent on their parents for warmth and food.
The Cattle Egret can be confused with other white egrets, but its shorter neck, more robust build, and behavior around livestock help distinguish it.
The diet is varied, primarily consisting of insects like grasshoppers, crickets, and flies. They also consume spiders, frogs, small reptiles, and occasionally bird eggs and chicks. They are known to forage in fields, often near grazing animals, and have been observed following farm machinery to catch disturbed prey.
The Cattle Egret is classified as Least Concern by the IUCN, with an extensive range and a large, stable population. Its successful colonization of new areas has led to it being considered an invasive species in some regions, though it has not yet been noted to have significant negative impacts.
24-11-2020 MARJALES DE INTERIOR, ALBUFERA - 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.
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.

22-11-2020 PEGO MARJAL, ALICANTE - COMMON CHIFFCHAFF (Phylloscopus collybita)
%2020.jpg)
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.
22-11-2020 LA FONT EN CARROS, VALENCIA - BLACK REDSTART (FEMALE) (Phoenicurus ochruros)
%20(Phoenicurus%20ochruros)%2021.jpg)
The Black Redstart (Phoenicurus ochruros) is a small, charismatic passerine bird, exhibiting a blend of dark and vibrant plumage. Males are distinguished by their dark grey to black upperparts and breast, with a striking orange-red rump and tail. Females and juveniles are more subdued in color, with grey to grey-brown feathers and the same vivid tail coloration that is the hallmark of the species.
Adult males are easily identified by their dark upperparts and black breast, contrasting with the orange-red lower rump and tail. The belly and undertail may vary from blackish-grey to orange-red, depending on the subspecies. Females and juveniles are less conspicuous, with overall greyer tones and a distinctive orange-red rump and tail. The presence of pale fringes on the secondaries forms a whitish wing panel in some subspecies.
The Black Redstart has adapted remarkably to urban environments, often found nesting in crevices or holes within buildings. Originally a dweller of stony mountainous regions, it now thrives in industrial areas with similar structural features.
%20(Phoenicurus%20ochruros)%2022.jpg)
This species is widely distributed across south and central Europe, Asia, and north-west Africa. It is a resident in milder regions, while populations in the northeast migrate to warmer areas during winter.
The Black Redstart is known for its robin-like movements, including quick ducks of the head and body, and frequent tail flicking. Males possess a rattling song and a tick call, adding to their distinctive presence.
The Black Redstart's vocal repertoire includes a variety of calls, which differ among subspecies. The male's song is a rattling melody, while its call is a sharp 'tick', often heard during its active foraging.
%20(Phoenicurus%20ochruros)%2023.jpg)
Typically monogamous, the Black Redstart begins breeding in mid-April. Nests are built by females in sheltered nooks, lined with soft materials. Clutches consist of 4 to 6 eggs, incubated primarily by the female. Both parents tend to the fledglings, which leave the nest after 12 to 19 days.
The Common Redstart shares some similarities but can be distinguished by its different behavior, ecological requirements, and less dark plumage.
The Black Redstart's diet includes insects, which it often catches mid-flight. It is also known to forage in coastal areas for tiny crustaceans and flies.
The IUCN Red List classifies the Black Redstart as Least Concern, indicating a stable population across its extensive range.

20-11-2020 GALISTEO, CACERAS - BLACK STORK (BLACK STORK (ciconia nigra)
The black stork (Ciconia nigra) is a large bird in the stork family Ciconiidae. It was first described by Carl Linnaeus in the 10th edition of his Systema Naturae. Measuring on average 95 to 100 cm (37 to 39 in) from beak tip to end of tail with a 145-to-155 cm (57-to-61 in) wingspan, the adult black stork has mainly black plumage, with white underparts, long red legs and a long pointed red beak. A widespread but uncommon species, it breeds in scattered locations across Europe (predominantly in Portugal and Spain, and central and eastern parts), and east across the Palearctic to the Pacific Ocean. It is a long-distance migrant, with European populations wintering in tropical Sub-Saharan Africa, and Asian populations in the Indian subcontinent. When migrating between Europe and Africa, it avoids crossing broad expanses of the Mediterranean Sea and detours via the Levant in the east, the Strait of Sicily in the center, or the Strait of Gibraltar in the west. An isolated, non-migratory, population occurs in Southern Africa.
