26-4-2019 PEGO MARJAL, ALICANTE - EURASIAN TREE SPARROW (MALE) (Passer montanus)


The Eurasian tree sparrow (Passer montanus) is a charming passerine bird, easily recognized by its rich chestnut crown and nape, and a distinctive black patch on each pure white cheek. Both sexes are similarly adorned, and the juveniles mirror the adults, albeit with slightly duller hues. This species is somewhat smaller than the closely related house sparrow, and its size is approximately 12.5–14 cm in length, with a wingspan of about 21 cm.

To identify the Eurasian tree sparrow, look for the kidney-shaped black ear patch on each white cheek, the black chin and throat, and the light brown upperparts streaked with black. The wings bear two narrow white bars, and the legs are pale brown. The bill is lead-blue in summer, darkening almost to black in winter. Unlike the house sparrow, there is no sexual dimorphism in plumage, making both males and females equally easy to identify.

In Europe, the Eurasian tree sparrow is typically found in lightly wooded open countryside, while in eastern Asia, it is more common in urban settings. It prefers nesting in natural cavities, holes in buildings, or even the abandoned nests of other large birds. This species is not typically found in mountainous regions, despite its scientific name suggesting otherwise.


The Eurasian tree sparrow has a broad distribution across temperate Eurasia and Southeast Asia, and it has been introduced to other regions such as the United States. Its range extends from Europe across Asia to the Lena River and south to the northern regions of Turkey, the Caucasus, Kazakhstan, Mongolia, and North Korea.

The Eurasian tree sparrow is a sociable bird, often seen in flocks. It is sedentary in most of its range, but northern populations may migrate southward in winter. This species is known for its untidy nests and can breed in a variety of locations, from tree holes to urban structures.

The Eurasian tree sparrow does not have a true song but communicates with a series of excited "tschip" calls during courtship and other monosyllabic chirps for social interactions. Its flight call is a harsh "teck."


Breeding maturity is reached within a year, and the typical clutch consists of five or six eggs. Both parents incubate the eggs for about 12-13 days, and the chicks fledge after 15-18 days. The species may raise two or three broods each year.

The Eurasian tree sparrow can be confused with the house sparrow, but the latter has a grey, not brown, crown and lacks the distinctive face pattern of the tree sparrow.

Primarily a seed and grain eater, the Eurasian tree sparrow forages on the ground in flocks. During the breeding season, it also consumes invertebrates to feed its young. It is known to visit feeding stations, particularly for peanuts.

With an extensive range and large population, the Eurasian tree sparrow is classified as Least Concern globally. However, there have been significant declines in western European populations due to changes in farming practices, such as increased use of herbicides and loss of winter stubble fields.

26-4-2019 PEGO MARJAL, 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 the latter's larger size and black band at the tip of the 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.

24-4-2019 MONTE CORONA, VALENCIA - EURASIAN COLLARED DOVE (Streptopelia decaocto)


The Eurasian collared dove, collared dove or Turkish dove (Streptopelia decaocto) is a dove species native to Europe and Asia; it was introduced to Japan, North America and islands in the Caribbean.

The Eurasian collared dove is not migratory, but is strongly dispersive. Over the last century, it has been one of the great colonisers of the bird world, travelling far beyond its native range to colonise colder countries, becoming a permanent resident in several of them. Its original range at the end of the 19th century was warm temperate and subtropical Asia from Turkey east to southern China and south through India to Sri Lanka. In 1838 it was reported in Bulgaria, but not until the 20th century did it expand across Europe, appearing in parts of the Balkans between 1900 and 1920, and then spreading rapidly northwest, reaching Germany in 1945, Great Britain by 1953 (breeding for the first time in 1956), Ireland in 1959, and the Faroe Islands in the early 1970s. 


Subsequent spread was 'sideways' from this fast northwestern spread, reaching northeast to north of the Arctic Circle in Norway and east to the Ural Mountains in Russia, and southwest to the Canary Islands and northern Africa from Morocco to Egypt, by the end of the 20th century. In the east of its range, it has also spread northeast to most of central and northern China, and locally (probably introduced) in Japan. It has also reached Iceland as a vagrant (41 records up to 2006), but has not colonised successfully there.

The Eurasian collared dove is a medium-sized dove, distinctly smaller than the wood pigeon, similar in length to a rock pigeon but slimmer and longer-tailed, and slightly larger than the related European turtle dove, with an average length of 32 cm (13 in)[14] from tip of beak to tip of tail, with a wingspan of 47–55 cm (19–22 in), and a weight of 125–240 g (4.4–8.5 oz). It is grey-buff to pinkish-grey overall, a little darker above than below, with a blue-grey underwing patch. The tail feathers are grey-buff above, and dark grey and tipped white below; the outer tail feathers are also tipped whitish above. It has a black half-collar edged with white on its nape from which it gets its name. The short legs are red and the bill is black. 


The iris is red, but from a distance the eyes appear to be black, as the pupil is relatively large and only a narrow rim of reddish-brown iris can be seen around the black pupil. The eye is surrounded by a small area of bare skin, which is either white or yellow. The two sexes are virtually indistinguishable; juveniles differ in having a poorly developed collar, and a brown iris. The subspecies S. d. xanthocycla differs in having yellow rather than white eye-rings, darker grey on the head and the underparts a slightly darker pink.
The song is a goo-GOO-goo. The Eurasian collared dove also makes a harsh loud screeching call lasting about two seconds, particularly in flight just before landing. A rough way to describe the screeching sound is a hah-hah.

Eurasian collared doves cooing in early spring are sometimes mistakenly reported as the calls of early-arriving common cuckoos and, as such, a mistaken sign of spring's return.

26-4-2019 PEGO MARJAL, ALICANTE - FIELD BINDWEED (Convolvulus arvensis)


Convolvulus arvensis, or field bindweed, is a species of bindweed in the Convolvulaceae native to Europe and Asia. It is a rhizomatous and climbing or creeping herbaceous perennial plant with stems growing to 0.5–2 metres (1.6–6.6 ft) in length. It is usually found at ground level with small white and pink flowers.

Other common names, mostly obsolete, include lesser bindweed, European bindweed, withy wind (in basket willow crops), perennial morning glory, small-flowered morning glory, creeping Jenny, and possession vine.

Convolvulus arvensis is a perennial vine that typically climbs to 1 metre (3.3 ft). The vine produces woody rhizomes from which it resprouts in the spring, or when the aboveground vines are removed.

The leaves are spirally arranged, linear to arrowhead-shaped, 2–5 cm (0.79–1.97 in) long and alternate, with a 1–3 cm (0.39–1.18 in) petiole. The flowers are trumpet-shaped, 1–2.5 cm (0.39–0.98 in) diameter, white or pale pink, with five slightly darker pink radial stripes. Flowering occurs in the mid-summer (in the UK, between June and September) when white to pale pink, funnel-shaped flowers develop. Flowers are approximately 0.75–1 in (1.9–2.5 cm) across and are subtended by small bracts. Fruit are light brown, rounded and 0.125 inches (3.2 mm) wide. Each fruit contains 2 or 4 seeds that are eaten by birds and can remain viable in the soil for decades. The stems climb by twisting around other plant stems in a counter-clockwise direction.

26-4-2019 PEGO MARJAL, ALICANTE - SCARLET PIMPERNEL (Lysimachia arvensis)


Lysimachia arvensis, syn. Anagallis arvensis, commonly known as scarlet pimpernel, red pimpernel, red chickweed, poor man's barometer, poor man's weather-glass, shepherd's weather glass or shepherd's clock, is a species of low-growing annual plant with brightly coloured flowers, most often scarlet but also bright blue and sometimes pink. The native range of the species is Europe and Western Asia and North Africa. The species has been distributed widely by humans, either deliberately as an ornamental flower or accidentally. L. arvensis is now naturalised almost worldwide, with a range that encompasses the Americas, Central and East Asia, the Indian Subcontinent, Malesia, the Pacific Islands, Australasia and Southern Africa.

This common European plant is generally considered a weed and is an indicator of light soils, though it grows opportunistically in clay soils as well. The origin of the name pimpernel comes from late Middle English pympernele [1400–50], derived from Middle French pimprenelle, from Old French piprenelle, and ultimately from Vulgar Latin *piperīnella (piper 'pepper' + -īn- '-ine' + -ella diminutive suffix).

The flower serves as the emblem of the fictional hero the Scarlet Pimpernel.


When found as a summer annual, the scarlet pimpernel has a low-growing creeping habit, but as a winter annual, it forms a half-rosette with an upright stem. It has weak sprawling stems with square cross-section growing to about 5–30 centimetres (2–12 in) long. They bear bright green, soft, ovate sessile leaves in opposite pairs. The orange, red or blue, radially symmetric flowers, about 10–15 millimetres (0.4–0.6 in) in diameter, are produced singly in the leaf axils from spring to autumn. The petal margins are somewhat crenate and have small glandular hairs. The stamens have lollipop hairs and therefore attract a variety of pollinators, especially flies, but the flowers are also capable of autopollination. The dehiscent capsule fruits ripen from August to October in the northern hemisphere. The weight of the fruiting body bends the stem, and the seeds are transported by the wind or rain. Blue-flowered plants (treated as L. arvensis f. azurea by some sources) are common in some areas, such as the Mediterranean region, and should not be confused with the related blue pimpernel, Lysimachia foemina. In 2007, a molecular phylogenetic study showed that Lysimachia foemina is more closely related to Lysimachia monelli than to Lysimachia arvensis, and should be treated as a separate species (all three species were then placed in Anagallis). The species has a diploid chromosome count of 2n=40.

Scarlet pimpernel flowers open only when the sun shines, and even close in overcast conditions. This habit leads to names such as "shepherd's weather glass". It has been observed along the verges of salted roads, creating a broad red band along the roadside.

24-4-2019 CREU DE LONGA, VALENCIA - GREY HERON (Ardea cinerea)


The Grey Heron (Ardea cinerea) is a statuesque wading bird belonging to the family Ardeidae. It is a familiar sight in both rural and urban settings, often seen standing stoically along the water's edge. An adult Grey Heron is a large bird, reaching up to 100 cm in height, with a wingspan between 155 to 195 cm. It weighs between 1 to 2 kg. The plumage is predominantly ashy-grey above, with a greyish-white underbelly and some black on the flanks. A striking feature is the white head and neck adorned with a broad black stripe that extends from the eye to the black crest. The beak is pinkish-yellow, long, and sharply pointed, while the legs are a brown hue.
When identifying the Grey Heron, look for the white head with the black supercilium and crest, the long grey neck, and the ashy-grey wings and back. The underparts are lighter, and the legs are long and brown. Juveniles can be distinguished by their duller grey neck and smaller crest. The beak is a useful indicator of age, being brighter in breeding adults.


Grey Herons are highly adaptable and can be found in a variety of watery habitats including lakes, rivers, ponds, marshes, and coastal environments. They require shallow waters for foraging or areas with shelving margins where they can wade.

Native to temperate Europe and Asia, as well as parts of Africa, the Grey Heron has a broad range. Northern populations may migrate southwards in autumn, while others remain resident year-round. Vagrant sightings have occurred in the Caribbean, Bermuda, and parts of North America.

The Grey Heron exhibits a slow, deliberate flight with its neck retracted in an S-shape. It is known for its solitary foraging habits, often standing motionless or stalking prey through shallow waters. It is also a communal rooster, often found in trees or cliffs at night.


The primary call of the Grey Heron is a loud croaking "fraaank." At breeding colonies, a variety of guttural and raucous noises can be heard, including greeting calls between mates and alarm calls when predators are nearby.

Breeding takes place in colonies, or heronries, typically in high trees near water. Nests are reused and added to each year. The breeding season sees a clutch of three to five bluish-green eggs laid, which both parents incubate. Chicks fledge at 7-8 weeks old.

The Grey Heron can be confused with the larger North American Great Blue Heron or the South American Cocoi Heron. However, it can be distinguished by its size and the coloration of its flanks and thighs.

Grey Herons are apex predators within their ecosystem, feeding on a variety of aquatic creatures such as fish, amphibians, crustaceans, and insects. They have also been known to consume small mammals and juvenile birds.

The Grey Heron is classified as Least Concern by the IUCN, indicating a stable and widespread population.

24-4-2019 CREU DE LONGA, VALENCIA - LITTLE STINT (Calidris minuta)


The Little Stint, scientifically known as Calidris minuta, is a diminutive wader, a member of the family Scolopacidae. It is recognized by its small stature, fine dark bill, and dark legs, which set it apart from other waders, save for its close relatives, the dark-legged stints. This species exhibits a fine bill tip, unwebbed toes, and a notable long primary projection.

This bird nests on a scrape in bare ground, laying 3–5 eggs. It is polygamous, and male and female may incubate separate clutches.
Food is small invertebrates picked off the mud.


In breeding plumage, the adult Little Stint can be identified by an orange hue on the breast, a stark white throat, and a pronounced white V on the back. Winter plumage makes identification more challenging, while juveniles can be spotted by their pale crown stripes and a faintly pinkish breast. The bird's call is a distinctive sharp "stit."

The Little Stint is found in arctic regions during the breeding season, favoring open, bare ground for nesting.

A true long-distance migrant, the Little Stint breeds in the arctic realms of Europe and Asia. When not breeding, it travels extensively to wintering grounds in Africa and south Asia. It has also been recorded as a vagrant in North America and Australia.


The Little Stint is known for its gregarious nature during the non-breeding season, often forming substantial flocks with other Calidris waders, particularly the Dunlin. These flocks are commonly seen on coastal mudflats or at the edges of inland pools.

Polygamous by nature, the Little Stint lays 3-5 eggs in a scrape on the ground. Both males and females may incubate separate clutches, a unique aspect of their breeding behavior.

The diet of the Little Stint consists of small invertebrates, which it picks off from the mud.


The Little Stint is currently listed as Least Concern by the IUCN, indicating that it is not at immediate risk of population decline. However, its numbers are influenced by the population dynamics of lemmings, which in turn affect predation rates by other Arctic species. The Little Stint is also protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA).


The Little Stint is a very small wading bird that breeds in the Arctic tundra of Europe and Asia and migrates to wintering grounds in Africa, South Asia, and southern Europe. Key characteristics include its small size, short, straight black bill, and black legs, with a brownish-grey back and white underside. They are often seen in flocks on estuaries and muddy shores, sometimes joining other waders like Dunlin. 


Physical characteristics

Size: Tiny wading bird, smaller than a Dunlin.
Bill: Short, straight, and black.
Legs: Medium-length and black.
Plumage: Brownish-grey above and white underneath; in winter, it is grey above.
Juvenile appearance: Autumn birds have two pale stripes or "braces" down their back. 


Habitat and behavior

Habitat: Prefers estuaries and muddy shores of wetlands.
Social behavior: Often found in flocks, sometimes mixed with other waders.
Migration: A long-distance migrant, with most birds seen passing through the UK in autumn.

Breeding: Nests on the tundra in northern Scandinavia and Siberia. 
Geographic range
Breeding: Arctic Europe and Asia.
Wintering: Africa, South Asia, and southern Europe.
Vagrant: Occasionally seen in North America and Australia. 

26-4-2019 PEGO MARJAL, ALICANTE - WHINCHAT ( Saxicola rubetra)


The whinchat (Saxicola rubetra) is a small migratory passerine bird breeding in Europe and western Asia and wintering in central Africa. At one time considered to be in the thrush family, Turdidae, it is now placed in the Old World flycatcher family, Muscicapidae. Both sexes have a strong supercilium, brownish upper parts mottled darker, a pale throat and breast, a pale buff to whitish belly, and a blackish tail with white bases to the outer tail feathers, but in the breeding season, the male has an orange-buff throat and breast.The whinchat (Saxicola rubetra) is a small migratory passerine bird breeding in Europe and western Asia and wintering in central Africa. At one time considered to be in the thrush family, Turdidae, it is now placed in the Old World flycatcher family, Muscicapidae. Both sexes have a strong supercilium, brownish upper parts mottled darker, a pale throat and breast, a pale buff to whitish belly, and a blackish tail with white bases to the outer tail feathers, but in the breeding season, the male has an orange-buff throat and breast.


The whinchat is a solitary species, favouring open grassy country with rough vegetation and scattered small shrubs. It perches in elevated locations ready to pounce on the insects and other small invertebrates that form its diet. The nest is built by the female on the ground in coarse vegetation, with a clutch of four to seven eggs being laid. The hen incubates the eggs for about thirteen days and then both parents feed the nestlings. Fledging takes place about eighteen days after hatching and the parents continue to feed the young for another fortnight. Moulting takes place in late summer before the migration southwards, and again on the wintering grounds in Africa before the migration northwards in spring. The whinchat is a common species with a wide range and the International Union for Conservation of Nature has classified it as being of "least concern".

26-4-2019 PEGO MARJAL, ALICANTE - WESTERN YELLOW WAGTAIL (Motacilla flava)


The Western Yellow Wagtail, Motacilla flava, is a small, graceful passerine bird belonging to the wagtail family, Motacillidae. This species is noted for its slender build and the characteristic long, constantly wagging tail, a hallmark of its genus. Among its European relatives, it boasts the shortest tail. The adult male in breeding plumage is predominantly olive above with a vibrant yellow underbelly. Females and non-breeding males may exhibit a paler yellow, often intermixed with white.

To identify the Western Yellow Wagtail, look for a bird measuring about 15–16 cm in length. Breeding males display a variety of head colors and patterns, which can be quite distinctive, depending on the subspecies. In general, males have a more vivid plumage compared to the females, which are more subdued and often have a greenish wash.


This insectivorous bird favors open country near water sources, such as wet meadows, where it can be seen foraging for food.

The Western Yellow Wagtail breeds across much of temperate Europe and Asia. It is a resident bird in the milder parts of its range, like western Europe. However, populations from the north and east undertake migrations to Africa and south Asia to escape the winter chill.


The Western Yellow Wagtail is known for its dynamic tail movement, which it exhibits while walking on the ground. It is a sociable bird, often seen in small flocks during migration or in its wintering grounds.

The call of the Western Yellow Wagtail is a distinctive high-pitched 'jeet', which can be heard during its active periods.

Breeding takes place in tussocks, where the female lays a clutch of 4–8 speckled eggs. The nest is often situated close to the ground, concealed within dense vegetation.


The Western Yellow Wagtail can be confused with other wagtail species, but its shorter tail and the color variations in the breeding male's head plumage are helpful distinguishing features.

As an insectivore, the Western Yellow Wagtail feeds primarily on insects, which it catches with quick, darting movements on the ground or in flight.

The IUCN Red List categorizes the Western Yellow Wagtail as Least Concern, indicating that, currently, there are no significant threats to its global population.

24-4-2019 CREU DE LONGA, VALENCIA - EUROPEAN MOORHEN (Gallinula chloropus)


The common moorhen, known scientifically as Gallinula chloropus, is a bird of the rail family, Rallidae. It is a bird of striking appearance, with a mix of black and brown plumage, a white under-tail, and white streaks along its flanks. Its legs are a vibrant yellow, and it sports a distinctive red frontal shield. The bill is a matching red with a yellow tip. Juveniles are a duller brown and do not have the red shield.
Adult moorhens can be identified by their red frontal shield, which has a rounded top and fairly parallel sides. The tailward margin of the red unfeathered area is smoothly curved. Their yellow legs and the combination of their black and brown plumage with white markings make them quite distinctive. The young are browner and lack the red shield, making them less conspicuous.

The common moorhen is found in a variety of wetland habitats, including marshes, ponds, canals, and lakes that are rich in vegetation. It is also known to inhabit city parks with suitable water bodies.

24-4-2019 CREU DE LONGA, VALENCIA - COMMON GREENSHANK (Tringa nebularia)


The Common Greenshank, Tringa nebularia, presents itself as a graceful wader from the extensive Scolopacidae family. Its name, derived from the Neo-Latin term for the green sandpiper and the Latin for "mist," alludes to its marshy dwellings. In breeding plumage, it dons a brown attire, while in winter, it adopts a more subdued grey-brown. Notably larger than its cousin, the Common Redshank, it boasts long greenish legs and a long bill with a grey base, which appears upturned when the bird is in water.

Upon sighting, one may observe the white wedge on its back during flight. The bill's shape is distinctive, and its size is a helpful indicator, being somewhat larger than the Common Redshank. The bird's call, a rapid succession of three short fluty notes, can be transcribed as "teu-teu-teu."

The Common Greenshank favors dry ground adjacent to marshy areas for breeding, indicative of its preference for damp environments.


A subarctic species, the Common Greenshank breeds from northern Scotland, spreading east across northern Europe and the Palearctic. It is migratory, seeking winter refuge in Africa, the Indian subcontinent, and Australasia, typically near freshwater.

This bird is migratory, breeding on dry ground near marshy areas and laying about four eggs in a ground scrape.

The bird's vocalizations consist of a series of three short fluty notes, which can be heard as "teu-teu-teu."


The Common Greenshank nests on dry ground in proximity to marshes, where it lays approximately four eggs in a simple ground scrape.

The Marsh Sandpiper may appear similar when the Common Greenshank is in water, but the latter's bill shape is a distinguishing feature.

The diet of the Common Greenshank includes small invertebrates, and it will opportunistically consume small fish and amphibians.

The IUCN lists the Common Greenshank as Least Concern, indicating a stable population. However, under the Australian EPBC Act, it was listed as Endangered in 2024. It is also a subject of the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA). 


Key Characteristics

Appearance: Grey-brown back, silvery-white belly, dark streaks on breast (breeding), long green legs, long bill slightly upturned and dark at the tip.
Size: About 30-35 cm long with a wingspan of 55-69 cm.
Flight: Clipped wingbeats, zigzag flight, with toes extending past the tail; white wedge on rump visible. 

Behavior & Diet
Feeding: Hunts by sight in shallow water, eating worms, snails, crustaceans, insects, and small fish.
Social: Often solitary or in small, wary groups, described as nervous and excitable.
Vocalization: Calls include a clear, ringing "tew" or "tyu," and complex songs during breeding. 

Habitat & Migration
Breeding: Bogs, moors, and edges of northern forests (e.g., Scotland, Northern Europe).
Wintering/Migration: Coastal mudflats, estuaries, and inland freshwater wetlands worldwide.
Migration: A passage migrant, visiting UK and other areas during migration and winter. 

24-4-2019 CREU DE LONGA, VALENCIA - GLOSSY IBIS (Plegadis falcinellus)


The Glossy Ibis is a medium-sized wading bird with dark, iridescent plumage, a long curved bill, and long legs. They are found in wetlands and wet fields across much of the globe, where they forage in flocks for a diet of insects, crustaceans, amphibians, and small fish. Their habitat is threatened by drainage and other wetland alterations. 

Appearance
Plumage: A rich chestnut-brown body, with metallic green and purple sheens on the wings and back, especially on breeding adults.
Bill: A long, down-curved bill, often greenish-brown.
Size: About 23 inches (58 cm) long with a 36-inch (91 cm) wingspan.
Distinguishing features: Breeding adults have fine white lines around the base of their bill and a reddish-brown or cobalt-blue facial patch.
In flight: They fly with their neck outstretched and legs trailing straight behind. 

Habitat and range
Habitat: Found in a variety of wetland environments, including freshwater and saltwater marshes, rice fields, and riverbanks.
Range: A cosmopolitan species found in parts of Europe, Asia, Africa, Australia, North America, and South America. 


Diet and feeding
Diet: Omnivorous, feeding on insects (like beetles, dragonflies, and grasshoppers), worms, crustaceans (like crayfish and leeches), small fish, and amphibians.
Feeding behavior: They forage by wading in shallow water and probing the mud with their bills, which are equipped with sensory organs to detect vibrations.
Flocking: They typically forage in groups, sometimes with other species like egrets. 

Reproduction
Nesting: They are colonial nesters, building nests in vegetation like reeds or tamarisks.
Eggs: Typically lay 3-4 eggs, with both parents participating in nest building and feeding the young. 

Conservation
Status: Not listed as threatened globally by the IUCN.
Threats: Local populations can be threatened by habitat alteration, such as drainage and irrigation, and the invasion of exotic plants. 

24-4-2019 CREU DE LONGA, VALENCIA - LITTLE EGRET (Egretta garzetta)


The Little Egret, Egretta garzetta, is a dainty heron adorned in pure white plumage. It is characterized by a slender black beak, long black legs, and, notably in the western race, yellow feet. This elegant bird is a sight to behold with its graceful neck and poised stance.

Adult Little Egrets measure between 55–65 cm in length with a wingspan of 88–106 cm, and weigh 350–550 g. Their plumage is predominantly white, though some may exhibit bluish-grey coloration. Breeding adults boast ornate nape plumes reaching about 150 mm, along with distinctive feathers on the breast and elongated scapulars. The bill and lores are black, with greenish-grey skin at the base of the lower mandible and around the eye, which houses a yellow iris. Legs are black with contrasting yellow feet, though juveniles may have greenish-black legs and duller feet. The subspecies E. g. nigripes is distinguished by yellow skin between the bill and eye, and blackish feet.


The Little Egret frequents a variety of wetland habitats, from the shores of lakes and rivers to marshes and coastal regions. It is often found in open environments, such as mangroves, swamps, mudflats, and sandy beaches, as well as human-altered landscapes like rice fields.

The species has a broad breeding distribution across warm temperate to tropical regions of Asia, Africa, Australia, and Europe. Northern populations are migratory, wintering in Africa and southern Asia, while others remain as permanent residents in warmer areas.

Little Egrets are social yet territorial when feeding. They exhibit a range of foraging behaviors, from active chasing to patient ambush. Their movements are often in response to the presence of other animals, which may stir up prey.


The Little Egret's vocalizations include croaking and bubbling sounds at breeding colonies and a harsh alarm call when disturbed. These calls are similar to those of the Black-crowned Night Heron and the Cattle Egret.

Breeding colonies are often mixed with other water birds. Nests are platforms of sticks located in trees, shrubs, or reed beds. Clutches typically consist of three to five bluish-green eggs, incubated by both parents for about three weeks. The young fledge at approximately six weeks old.


The Little Egret can be confused with other white egrets, particularly the Snowy Egret, which shares some of its New World range. However, the Little Egret is larger and has more varied foraging strategies.

The diet is diverse, including fish, amphibians, small reptiles, mammals, birds, crustaceans, molluscs, insects, spiders, and worms. The Little Egret employs various hunting techniques, both in water and on land, to capture its prey.

The Little Egret is classified as "Least Concern" by the IUCN. Conservation measures in the 20th century have allowed populations to recover in Europe, and the species has been expanding its range. It is now successfully colonizing new areas, including the New World.

24-4-2019 CREU DE LONGA, VALENCIA - BLACK WINGED STILT (Himantopus himantopus)


Striking large black-and-white wader with a thin, straight bill and bright pink legs, found in wetlands with open shallow water throughout much of Africa and Eurasia, often in brackish habitats. Some populations are migratory, departing northerly breeding grounds for warmer southern regions. Often forms noisy colonies on bare ground near water. Essentially unmistakable throughout much of its range, but compare with Pied Stilt in parts of Southeast Asia. Feeds by wading in water, picking from the water surface with its needle-like bill. In flight, long pink legs stick out far beyond the tail. Calls loudly and stridently, especially when alarmed during the breeding season.

The black-winged stilt (Himantopus himantopus) is a widely distributed, very long-legged wader in the avocet and stilt family Recurvirostridae. Its scientific name, Himantopus himantopus, is sometimes used to generalize a single, almost cosmopolitan species. Alternatively, it is restricted to the form that is widespread in Europe, Asia and Africa, which equals the nominate group of H. himantopus sensu lato. Meanwhile, the black-necked (H. mexicanus) and white-backed stilts (H. melanurus) both inhabit the Americas; the pied stilt (H. leucocephalus) ranges from Australasia and New Zealand. Today, most sources accept between one and four actual species. The taxonomic name Himantopus comes from Greek, meaning "strap-foot" or "thong-foot".


Adults are 33–36 cm (13–14 in) long, with long, pink legs, and a long, rather thin black bill. The birds are generally black above and white below, with a white head and neck (with a varying amount of black, species-dependent). Males have a black back, often with a greenish gloss or sheen. Females' backs have a brownish hue, contrasting with the black remiges. In populations where the top of the head is normally white (at least in winter), females tend to have less black on the head and neck the entire year-round, while males often have much more black, particularly in summer. This difference is not clear-cut, however, and males usually grow all-white head feathers in winter. 

Immature birds are grey, instead of black, and have a markedly sandy hue on their wings, with light feather fringes appearing as a whitish line in flight.


The breeding habitat of all these stilts is marshes, shallow lakes and ponds. Some populations are migratory and move to the ocean coasts in winter; those in warmer regions are generally resident or short-range vagrants. In Europe, the black-winged stilt is a regular spring overshoot vagrant north of its normal range, occasionally remaining to breed in northern European countries. Pairs successfully bred in Britain in 1987, and after a 27-year hiatus there were two instances of successful breeding in Southern England in 2014. 13 young were fledged in southern England in 2017.Four chicks were successfully fledged in northern England in 2022; this is believed to be the most northerly breeding success for the black-winged stilt.

These birds pick up their food from sand or water. They eat mainly insects and crustaceans.

24-4-2019 CREU DE LONGA, VALENCIA - WESTERN CATTLE EGRET (Bubulcus ibis ssp. ibis)


The western cattle egret (Bubulcus ibis) is a species of heron (family Ardeidae) found in the tropics, subtropics and warm temperate zones. Most taxonomic authorities lump this species and the eastern cattle egret together (called the cattle egret), but some (including the International Ornithologists' Union) separate them. Despite the similarities in plumage to the egrets of the genus Egretta, it is more closely related to the herons of Ardea. Originally native to parts of Asia, Africa and Europe, it has undergone a rapid expansion in its distribution and successfully colonised much of the rest of the world in the last century.

It is a white bird adorned with buff plumes in the breeding season. It nests in colonies, usually near bodies of water and often with other wading birds. The nest is a platform of sticks in trees or shrubs. Western cattle egrets exploit drier and open habitats more than other heron species. Their feeding habitats include seasonally inundated grasslands, pastures, farmlands, wetlands and rice paddies. They often accompany cattle or other large mammals, catching insect and small vertebrate prey disturbed by these animals. Some populations of the cattle egret are migratory and others show post-breeding dispersal.


The adult cattle egret has few predators, but birds or mammals may raid its nests, and chicks may be lost to starvation, calcium deficiency or disturbance from other large birds. This species maintains a special relationship with cattle, which extends to other large grazing mammals; wider human farming is believed to be a major cause of their suddenly expanded range. The cattle egret removes ticks and flies from cattle and consumes them. This benefits both species, but it has been implicated in the spread of tick-borne animal diseases.

The cattle egret has undergone one of the most rapid and wide reaching natural expansions of any bird species. It was originally native to parts of Southern Spain and Portugal, tropical and subtropical Africa and humid tropical and western Asia. In the end of the 19th century it began expanding its range into southern Africa, first breeding in the Cape Province in 1908. Cattle egrets were first sighted in the Americas on the boundary of Guiana and Suriname in 1877, having apparently flown across the Atlantic Ocean. It was not until the 1930s that the species is thought to have become established in that area.


The species first arrived in North America in 1941 (these early sightings were originally dismissed as escapees), bred in Florida in 1953, and spread rapidly, breeding for the first time in Canada in 1962. It is now commonly seen as far west as California. It was first recorded breeding in Cuba in 1957, in Costa Rica in 1958, and in Mexico in 1963, although it was probably established before that. In Europe, the species had historically declined in Spain and Portugal, but in the latter part of the 20th century it expanded back through the Iberian Peninsula, and then began to colonise other parts of Europe; southern France in 1958, northern France in 1981 and Italy in 1985. Breeding in the United Kingdom was recorded for the first time in 2008 only a year after an influx seen in the previous year. In 2008, cattle egrets were also reported as having moved into Ireland for the first time.

The massive and rapid expansion of the cattle egret's range is due to its relationship with humans and their domesticated animals. Originally adapted to a commensal relationship with large grazing and browsing animals, it was easily able to switch to domesticated cattle and horses. As the keeping of livestock spread throughout the world, the cattle egret was able to occupy otherwise empty niches. Many populations of cattle egrets are highly migratory and dispersive, and this has helped the species' range expansion. The species has been seen as a vagrant in various sub-Antarctic islands, including South Georgia, Marion Island, the South Sandwich Islands and the South Orkney Islands. A small flock of eight birds was also seen in Fiji in 2008.

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.

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.

24-4-2019 CREU DE LONGA, VALENCIA - GREY HERON (Ardea cinerea)


The Grey Heron (Ardea cinerea) is a statuesque wading bird belonging to the family Ardeidae. It is a familiar sight in both rural and urban settings, often seen standing stoically along the water's edge. An adult Grey Heron is a large bird, reaching up to 100 cm in height, with a wingspan between 155 to 195 cm. It weighs between 1 to 2 kg. The plumage is predominantly ashy-grey above, with a greyish-white underbelly and some black on the flanks. A striking feature is the white head and neck adorned with a broad black stripe that extends from the eye to the black crest. The beak is pinkish-yellow, long, and sharply pointed, while the legs are a brown hue.
When identifying the Grey Heron, look for the white head with the black supercilium and crest, the long grey neck, and the ashy-grey wings and back. The underparts are lighter, and the legs are long and brown. Juveniles can be distinguished by their duller grey neck and smaller crest. The beak is a useful indicator of age, being brighter in breeding adults.
