1-12-2020 EL PALMAR, VALENCIA - COMMON KINGFISHER (FEMALE) (Alcedo atthis)
%20(Alcedo%20atthis)%2020.jpg)
The Common Kingfisher (Alcedo atthis), also known as the Eurasian Kingfisher or River Kingfisher, is a vibrant, pocket-sized gem among birds. With its unmistakable silhouette characterized by a stout body, large head, and a long, sharp bill, it is a sight to behold. The male boasts a striking palette with blue upperparts, an orange belly, and a conspicuous white throat and collar. The female mirrors the male's vivid colors but can be discerned by her orange-red lower mandible with a black tip.
To identify the Common Kingfisher, look for its bright blue and orange plumage and its rapid, low flight over water. The male's bill is predominantly black with some red at the base, while the female's bill features an orange-red lower mandible. Juveniles resemble adults but have duller, greener upperparts and paler underparts. Their black bill and legs gradually acquire the adult coloration.

The Common Kingfisher is found along clear, slow-flowing streams and rivers, as well as lakes with well-vegetated banks. It prefers areas with overhanging branches that provide vantage points for hunting. In winter, it may move to coastal regions, frequenting estuaries, harbors, and rocky shores.
This species has a broad range across Eurasia and North Africa. It is a year-round resident in many parts of its range but migrates from colder regions where water bodies freeze in winter.
The Common Kingfisher is a solitary and highly territorial bird, particularly during the breeding season. It is known for its fast and direct flight, often creating a flash of electric blue as it moves along waterways. When hunting, it perches above the water before diving in to catch prey with remarkable precision.

The Common Kingfisher's call is a sharp, high-pitched whistle, often repeated in flight. When alarmed, it emits a harsher sound, and nestlings vocalize with a churring noise to signal hunger.
Breeding pairs form in the autumn, with each bird maintaining its own territory. The courtship involves chasing and ritual feeding. Nests are burrows tunneled into riverbanks, where the female lays glossy white eggs. Both parents share incubation duties, and the young fledge after about a month.
In its range, the Common Kingfisher could be confused with other small blue kingfishers. However, its rufous ear patches and specific head pattern are distinguishing features.
The diet of the Common Kingfisher is predominantly fish, complemented by aquatic insects and, in winter, crustaceans. It hunts by diving from perches, using specialized vision to locate prey underwater.
The Common Kingfisher is classified as Least Concern by the IUCN. It has a large, stable population and a vast global range. However, it remains sensitive to water pollution and habitat disturbance, which can impact local numbers.

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.
