9-1-2019 ALBUFERA, VALENCIA - NORTHERN LAPWING (Vanellus vanellus)
The northern lapwing (Vanellus vanellus), also known as the peewit or pewit, tuit or tewit, green plover, or (in Ireland and Great Britain) pyewipe or just lapwing, is a bird in the lapwing subfamily. It is common through temperate Eurosiberia.
The northern lapwing was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Tringa vanellus. The species is now placed with the other lapwings in the genus Vanellus that was introduced by the French zoologist Mathurin Jacques Brisson in 1760. The scientific name Vanellus is Medieval Latin for the northern lapwing and derives from vannus, a winnowing fan. The species is monotypic: no subspecies are recognised.
The name lapwing has been variously attributed to the "lapping" sound its wings make in flight, from the irregular progress in flight due to its large wings (the Oxford English Dictionary derives this from an Old English word meaning "to totter"), or from its habit of drawing potential predators away from its nest by trailing a wing as if broken. The names peewit, pewit, tuit or tew-it are onomatopoeic and refer to the bird's characteristic call.
Like the golden plovers, this species prefers to feed at night when there is moonlight.
The northern lapwing is a 28–33 cm (11–13 in) long bird with a 67–87 cm (26–34 in) wingspan and a body mass of 128–330 g (4.5–11.6 oz).[10] It has rounded wings and a crest. It is also the shortest-legged of the lapwings. It is mainly black and white, but the back is tinted green. The male has a long crest and a black crown, throat and breast contrasting with an otherwise white face. Females and young birds have shorter crests, and have less strongly marked heads, but plumages are otherwise quite similar.
This is a vocal bird in the breeding season, with constant calling as the crazed tumbling display flight is performed by the male. The typical contact call is a loud, shrill "pee-wit" from which they get their other name of peewit. Displaying males usually make a wheezy "pee-wit, wit wit, eeze wit" during their display flight; these birds also make squeaking or mewing sounds.
It is highly migratory over most of its extensive range, wintering further south as far as North Africa, northern India, Nepal, Bhutan and parts of China. It migrates mainly by day, often in large flocks. Lowland breeders in westernmost areas of Europe are resident. It occasionally is a vagrant to North America, especially after storms, as in the Canadian sightings after storms in December 1927 and in January 1966.
It is a wader that breeds on cultivated land and other short vegetation habitats. 3–4 eggs are laid in a ground scrape. The nest and young are defended noisily and aggressively against all intruders, up to and including horses and cattle.
In winter, it forms huge flocks on open land, particularly arable land and mud-flats.
It feeds primarily on insects and other small invertebrates. This species often feeds in mixed flocks with golden plovers and black-headed gulls, the latter often robbing the two plovers, but providing a degree of protection against predators. Additionally, they use one leg to beat the ground until worms surface, known as a variation of worm charming.
9-1-2019 DEVESA, VALENCIA - BLACK REDSTART (FEMALE) (Phoenicurus ochruros)
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.

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.
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.
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.
9-1-2019 ALBUFERA, VALENCIA - NORTHERN LAPWING (Vanellus vanellus)
The northern lapwing (Vanellus vanellus), also known as the peewit or pewit, tuit or tewit, green plover, or (in Ireland and Great Britain) pyewipe or just lapwing, is a bird in the lapwing subfamily. It is common through temperate Eurosiberia.

9-1-2019 RACO DE OLLA, VALENCIA - MALLARD (MALE & FEMALE) (Anas platyrhynchos)
%20(Anas%20platyrhynchos)%2020.jpg)
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.
9-1-2019 ALBUFERA, VALENCIA - LITTLE EGRET (Egretta garzetta)
The little egret is a small, white heron with black legs, a black bill, and bright yellow feet that are a key identifier. These birds are found across Europe, Africa, Asia, and Australia and are highly social, often seen hunting in flocks. During breeding season, they develop long, elegant plumes on their heads and backs. They are opportunistic hunters that primarily eat fish and crustaceans in shallow water, sometimes using their feet to stir up prey.
Physical characteristics
Size: 55–65 cm in length with a wingspan of 88–95 cm.
Weight: 350–550g.
Plumage: Entirely white, including long plumes on the crest, back, and chest during breeding season.
Legs and feet: Black legs with distinctive yellow feet.
Bill: Pointed, jet-black bill.
Habitat and distribution
Global range: Found in tropical and temperate regions of Europe, Africa, Asia, and Australia.
Habitat: Prefers shallow waters like coastal areas, estuaries, and freshwater wetlands, and can be found in both rural and urban areas.
UK presence: A recent colonizer, first breeding in 1996, but now a common resident in much of the country.
9-1-2019 ALBUFERA, VALENCIA - BLACK HEADED GULL (Chroicocephalus ridibundus)
%2020.jpg)
The black-headed gull (Chroicocephalus ridibundus) is a small gull that breeds in much of the Palearctic in Europe and Asia, and also locally in smaller numbers in coastal eastern Canada. Most of the population is migratory and winters further south, but many also remain in the milder areas of northwestern Europe. It was formerly sometimes cited as "common black-headed gull" to distinguish it from "great black-headed gull" (an old name for Pallas's gull).
Black-headed gulls were among the birds most heavily hit by the 2023 avian influenza outbreak, with over 4,000 birds killed in Great Britain by early May; similarly high mortality rates were also reported from France, the Netherlands, Italy and Germany.
%2021.jpg)
The black-headed gull is a bold and opportunistic feeder. It eats insects, fish, seeds, worms, scraps, and carrion in towns, or invertebrates in ploughed fields with equal facility. It is a noisy species, especially in colonies, with a familiar "kree-ar" call.
It displays a variety of behaviour and adaptations. Some of these include removing eggshells from the nest after hatching, begging co-ordination between siblings, differences between sexes, conspecific brood parasitism, and extra-pair paternity. They are found in a variety of different habitats.
9-1-2018 ALBUFERA, VALENCIA - GREY WAGTAIL (Motacilla cinerea)
%2021.jpg)
The Grey Wagtail, Motacilla cinerea, is a slender bird of the wagtail family, Motacillidae, with an overall length of approximately 18–19 cm. It bears a resemblance to the Yellow Wagtail but is distinguished by the yellow on its underside being confined to the throat and vent. The male, during the breeding season, is characterized by a striking black throat.
This species can be identified by its narrow white supercilium and a broken eye ring. The upperparts are a soft grey, while the underparts are predominantly whitish, with a contrasting yellow vent. Breeding males are notable for their black throats bordered by whitish moustachial stripes.
The Grey Wagtail is invariably found in association with running water during the breeding season. It may nest in natural settings or utilize man-made structures close to streams. Outside of breeding times, it can also be observed around lakes, coasts, and other watery environments.
The Grey Wagtail has a wide distribution across Eurosiberia, with several populations breeding in this region and migrating to tropical areas in Asia and Africa. Subspecies are found in the Azores, Madeira, Canary Islands, and from western Europe to central, east, and northeast Asia.
9-1-2018 ALBUFERA, VALENCIA - COMMON WATER CROWFOOT (Ranunculus aquatilis)
A member of the buttercup family, Common water-crowfoot displays white, buttercup-like flowers with yellow centres. It can form mats in ponds, ditches and streams during spring and summer.
Scientific name is Ranunculus aquatilis.
It can be seen in the UK from May to September.
Ranunculus aquatilis, the common water-crowfoot or white water-crowfoot, is a plant species of the genus Ranunculus, native throughout most of Europe and western North America, and also northwest Africa.
This is an aquatic plant, growing in mats on the surface of water. It has branching thread-like underwater leaves and toothed floater leaves. In fast flowing water the floaters may not be grown. The flowers are white petaled with yellow centres and are held a centimetre or two above the water. The floater leaves are used as props for the flowers and are grown at the same time.

8-1-2019 OLIVA CAMPO, VALENCIA - COMMON CHAFFINCH (MALE) (Fringilla coelebs)
%20(Fringilla%20coelebs)%2020.jpg)
The adult male Common chaffinch has a black forehead and a blue-grey crown, nape and upper mantle. The rump is a light olive-green; the lower mantle and scapulars form a brown saddle. The side of the head, throat and breast are a dull rust-red merging to pale creamy pink on the belly. The central pair of tail feathers are dark grey with a black shaft streak. The rest of the tail is black apart from the two outer feathers on each side which have white wedges. Each wing has a contrasting white panel on the coverts and a buff-white bar on the secondaries and inner primaries. The flight feathers are black with white on the basal portions of the vanes.
%20(Fringilla%20coelebs)%2022.jpg)
The secondaries and inner primaries have pale yellow fringes on the outer web whereas the outer primaries have a white outer edge. After the autumn moult, the tips of the new feathers have a buff fringe that adds a brown cast to the coloured plumage. The ends of the feathers wear away over the winter so that by the spring breeding season the underlying brighter colours are displayed. The eyes have dark brown irises and the legs are grey-brown. In winter the bill is a pale grey and slightly darker along the upper ridge or culmen, but in spring the bill becomes bluish-grey with a small black tip. The adult female is much duller in appearance than the male. The head and most of the upperparts are shades of grey-brown. The underparts are paler. The lower back and rump are a dull olive green. The wings and tail are similar to those of the male. The juvenile resembles the female.

7-1-2019 GANDIA MARJAL, VALENCIA - SPECKLED WOOD BUTTERFLY (Pararge aegeria)
The speckled wood (Pararge aegeria) is a butterfly found in and on the borders of woodland areas throughout much of the Palearctic realm. The species is subdivided into multiple subspecies, including Pararge aegeria aegeria, Pararge aegeria tircis, Pararge aegeria oblita, and Pararge aegeria insula. The color of this butterfly varies between subspecies. The existence of these subspecies is due to variation in morphology down a gradient corresponding to a geographic cline.
The background of the wings ranges from brown to orange, and the spots are either pale yellow, white, cream, or a tawny orange. The speckled wood feeds on a variety of grass species. The males of this species exhibit two types of mate locating behaviors: territorial defense and patrolling. The proportion of males exhibiting these two strategies changes based on ecological conditions. The monandrous female must choose which type of male can help her reproduce successfully. Her decision is heavily influenced by environmental conditions.
7-1-2019 GANDIA MARJAL, VALENCIA - EURASIAN COOT (Fulica atra)
%2020.jpg)
The Eurasian coot, Fulica atra, also known as the common coot or Australian coot, is a distinctive waterbird with a slaty-black body, a glossy black head, and a striking white bill topped with a white frontal shield. This bird is a member of the Rallidae family, which includes rails and crakes. Both sexes exhibit similar plumage, making them indistinguishable in the field.
Adult Eurasian coots measure 36–38 cm in length with a wingspan of 70–80 cm. Males are slightly heavier than females, weighing around 890 g compared to the females' 750 g. The species is characterized by its white bill and frontal shield, which contrast sharply with its all-black body. Juveniles are paler with a whitish breast and lack the facial shield, which develops fully by one year of age.
The Eurasian coot is found on freshwater lakes and ponds and has adapted well to urban environments, often seen in city parks and gardens with water bodies.
This bird has a broad range across the Old World, including Europe, Asia, Australia, New Zealand, and parts of North Africa. It is a resident in milder regions but migrates south and west from much of Asia during winter.
%2021.jpg)
The Eurasian coot is less secretive than many rails, often visible on open water or grasslands. It is territorial and aggressive during the breeding season, with both parents defending their territory. In non-breeding seasons, coots may form large flocks. They are reluctant flyers, preferring to run across water surfaces, and are known for bobbing their heads while swimming.
This species is known for its noisy demeanor, producing a variety of crackling, explosive, or trumpeting calls, which are often heard at night.
Coots build bulky, sometimes floating nests, concealed in vegetation or in the open. Both sexes construct the nest, with the male gathering materials. Clutches typically contain 6-10 buff-colored eggs speckled with black or dark brown. Both parents incubate the eggs, which hatch after 21-24 days. Chicks are precocial and nidifugous, with distinctive orange-red tips on their down.
Omnivorous in nature, the Eurasian coot consumes small live prey, including other birds' eggs, as well as algae, vegetation, seeds, and fruit. It employs various feeding techniques, both on land and in water.
The Eurasian coot is classified as Least Concern by the IUCN and is protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA).
7-1-2019 GANDIA MARJAL, VALENCIA - EUROPEAN ROBIN (Erithacus rubecula)
%2020.jpg)
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.
European robins are active during the day, however, they may also hunt insects on moonlit nights or near artificial light at night. These are generally solitary and territorial birds, and males are noted for their highly aggressive territorial behavior. They will fiercely attack other males and competitors that stray into their territories and may even attack other small birds without apparent provocation.
%2021.jpg)
European robins communicate using a variety of calls, including a ticking note that usually indicates anxiety or mild alarm. During the breeding season, robins produce a fluting, warbling song. Both the male and female sing during the winter, when they hold separate territories; the song then sounds more plaintive than the summer version.
The female typically moves a short distance from the summer nesting territory to a nearby area that is more suitable for winter feeding. The male keeps the same territory throughout the year. During the breeding season, males usually initiate their morning song an hour before civil sunrise and usually terminate their daily singing around thirty minutes after sunset. They may also sing at night, especially in urban areas that are artificially lit during the night.

6-1-2019 ADOR CAMPO, VALENCIA - LITTLE OWL (Athene noctua)
%2020.jpg)
This owl usually perches in an elevated position ready to swoop down on any small creature it notices. It feeds on prey such as insects and earthworms, as well as small vertebrates including amphibians, reptiles, birds and mammals. It may pursue prey on the ground and it caches surplus food in holes or other hiding places. A study of the pellets of indigestible material that the birds regurgitate found mammals formed 20 to 50% of the diet and insects 24 to 49%. Mammals taken included mice, rats, voles, shrews, moles and rabbits. The birds were mostly taken during the breeding season and were often fledglings, and including the chicks of game birds. The insects included Diptera, Dermaptera, Coleoptera, Lepidoptera and Hymenoptera. Some vegetable matter (up to 5%) was included in the diet and may have been ingested incidentally.
The little owl is territorial, the male normally remaining in one territory for life. However, the boundaries may expand and contract, being largest in the courtship season in spring. The home range, in which the bird actually hunts for food, varies with the type of habitat and time of year. Little owls with home-ranges that incorporate a high diversity of habitats are much smaller (< 2 ha) than those which breed in monotonous farmland (with home-ranges over 12 ha). Larger home-ranges result in increased flight activity, longer foraging trips and fewer nest visits. If a male intrudes into the territory of another, the occupier approaches and emits its territorial calls. If the intruder persists, the occupier flies at him aggressively. If this is unsuccessful, the occupier repeats the attack, this time trying to make contact with his claws. In retreat, an owl often drops to the ground and makes a low-level escape. The territory is more actively defended against a strange male as compared to a known male from a neighbouring territory; it has been shown that the little owl can recognise familiar birds by voice.
%2021.jpg)
The little owl is partly diurnal and often perches boldly and prominently during the day. If living in an area with a large amount of human activity, little owls may grow used to humans and will remain on their perch, often in full view, while people are around. The little owl has a life expectancy of about 16 years. However, many birds do not reach maturity; severe winters can take their toll and some birds are killed by road vehicles at night, so the average lifespan may be on the order of 3 years.
This owl becomes more vocal at night as the breeding season approaches in late spring. The nesting location varies with habitat, nests being found in holes in trees, in cliffs, quarries, walls, old buildings, river banks and rabbit burrows. A clutch of 3 to 5 eggs is laid (occasionally 2 to 8). The eggs are broadly elliptical, white and without gloss; they measure about 35.5 by 29.5 mm (1.40 by 1.16 in). They are incubated by the female who sometimes starts sitting after the first egg is laid. While she is incubating the eggs, the male brings food for her. The eggs hatch after 28 or 29 days. At first the chicks are brooded by the female and the male brings in food which she distributes to them. Later, both parents are involved in hunting and feeding them. The young leave the nest at about 7 weeks, and can fly a week or two later. Usually there is a single brood but when food is abundant, there may be two. The energy reserves that little owl chicks are able to build up when in the nest influences their post-fledgling survival, with birds in good physical condition having a much higher chance of survival than those in poor condition. When the young disperse, they seldom travel more than about 20 km (12 mi). Pairs of birds often remain together all year round and the bond may last until one partner dies.
6-1-2019 PEGO MARJAL, ALICANTE - COMMON BUZZARD (Buteo buteo)
%2019.jpg)
Common buzzards are medium-sized birds of prey found across Europe, Asia, and Africa, known for their broad wings and fan-shaped tail, and have a varied diet that includes small mammals, birds, and carrion.
