30-1-2017 MONTE CORONA, VALENCIA - MEDITERRANEAN PALE GLOW-WORM CATERPILLAR (Nyctophila reichii)

Nyctophila reichii, commonly known as the Mediterranean firefly, is a species of firefly. The species is very common in the southern and eastern part of the Iberian Peninsula.

Nyctophila reichii, the Mediterranean glow-worm, characterized by its orange

yellowish tone, is the species most recorded from both sources of information. 

We identified 95 larvae, 34 males and 25 females (including the 6 records that show both males and females). This species shows a clear Mediterranean and Southern distribution, with no records in the Northern provinces except one from Galicia (Spanish region north of Portugal).

The biology and phenology of this species is still unknown. Data of the survey allow us to show some phenological patterns for the period 2004-2010. Adult males and females were seen from late May until late July (Table 2). Despite the data it is still insufficient to draw conclusions about the relationship between latitude and day of adult emergence, the later records (second fortnight of July) correspond to the northern provinces of Spain. 

Larvae were found during the whole year across all of Spain, even during 

months when adults are present (June and July), although in lower numbers 

compared to the previous and subsequent months. The latter pattern may 

indicate a two year life-cycle as reported for other lampyrid species, i.e. L. 

noctiluca (Tyler, 2002). 

Males and females were often found in groups sometimes more than 200 

individuals within a 40m2 patch of riverside forest, or more than twelve males.

3-3-2017 MONTE CORONA, VALENCIA - RED CROSSBILL (MALE) (Loxia curvirostra)

The Red Crossbill is primarily identified by its call, a single note "chip" that varies between the different types. These calls are frequently given and are key to distinguishing between the various populations.

Breeding occurs in coniferous forests, with timing closely linked to the maturation of conifer seeds. Red Crossbills may nest at any time of year if they find an area with an adequate cone crop.

Similar species include the Two-barred Crossbill, Parrot Crossbill, Scottish Crossbill, and Cassia Crossbill. These species were once considered subspecies of the Red Crossbill but are now recognized as distinct, primarily based on call differences.

The diet of the Red Crossbill is specialized, consisting primarily of seeds from conifer cones. They use their unique bill shape to pry apart the scales of cones and access the seeds within.

The Red Crossbill is currently listed as Least Concern on the IUCN Red List, indicating that it is not at immediate risk of widespread decline.

2-3-2017 PEGO MARJAL, ALICANTE - EUROPEAN ROBIN (Erithacus rubecula)

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.

Baby robins are helpless at birth but reach the size of their parents after just two weeks. Robins fly at 17 to 32 mph. Robin have about 2,900 feathers. Only the male robin sings the "true robin song," and he sings it to declare his personal nesting territory.

But likely the most important reason is that the patch of red feathers serves as a warning to other robins to stay off their patch. Robins are highly territorial birds, and may wish to defend an area because it has good food and water provisions, or is a good place to find mates and raise their young.

European Robins eat seeds and berries during the winter. In summer they feed mostly on ground-dwelling invertebrates, even accompanying gardeners to grab insects and worms exposed by freshly turned soil.

Habitat. European Robins inhabit shaded woodlands ranging from backyard gardens to mossy coniferous forests. In general, this species frequents cool, damp, shady habitats that offer undergrowth for cover, perches for singing, small patches of bare ground for foraging, and walls, banks, or rocks for nesting.

2-3-2017 PEGO MARJAL, ALICANTE - 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.

2-3-2017 PEGO MARJAL, ALICANTE - BOOTED EAGLE (Hieraaetus pennatus

The booted eagle, Hieraaetus pennatus, is a medium-sized bird of prey, with a stature comparable to the common buzzard. It exhibits sexual dimorphism, with females being larger, weighing approximately 840–1,025 grams, while males are lighter at 510–770 grams. The species measures around 40 cm in length and boasts a wingspan ranging from 110 to 132 cm. It is characterized by two distinct plumage morphs: a pale variant with light grey feathers and a darker head and flight feathers, and a darker morph with mid-brown plumage and dark grey flight feathers.

When identifying the booted eagle, look for the white markings on the wings, often referred to as "landing lights," which are visible when the bird is in flight. The pale morph is dominant, but the darker morph can be more prevalent in certain eastern populations. The call of the booted eagle is a distinctive shrill "kli-kli-kli."

The booted eagle favors wooded, often hilly landscapes with some open areas. It breeds in rocky, broken terrain but is adaptable during migration, utilizing a variety of habitats except dense forests.

This raptor has a wide distribution, breeding in southern Europe, North Africa, and across Asia, with a disjunct breeding population in southwestern Africa. Northern populations are migratory, wintering in Sub-Saharan Africa and South Asia, while the southern African populations are sedentary.

The booted eagle is typically observed flying at low altitudes, making it quite conspicuous. It is often seen in pairs or as solitary individuals. The species is known for its sophisticated courtship rituals involving elaborate flight displays.

The booted eagle's vocalization is a piercing "kli-kli-kli," which can be heard during its flight.

Monogamous by nature, the booted eagle lays 1-2 eggs in a nest constructed from sticks and lined with green leaves, either in a tree or on a crag. The female incubates the eggs for about 45 days, while the male provides food. After hatching, the female continues to guard the nest and the young, with the male supplying all the nourishment until the chick fledges after 70-75 days.

The dark morph of the booted eagle may be confused with other local medium-sized birds of prey due to its coloration and size.

The booted eagle hunts small mammals, reptiles, and birds, often stooping from flight with wings folded and feet extended to capture its prey. In Southern Africa, birds are the most common prey, although frogs are also suggested to be an important dietary component elsewhere.

The booted eagle is currently listed as Least Concern on the IUCN Red List. However, there is a notable lack of research on this species, particularly the Southern African populations, which were only discovered in the 1980s. Changes in climate and human land use may influence migration patterns, underscoring the need for further study to understand the ecology and conservation status of this species.

1-3-2017 VILLALONGA RESERVOIR, VALENCIA - GREY HERON (Ardea cinerea)

The grey heron (Ardea cinerea) is a long-legged wading bird of the heron family, Ardeidae, native throughout temperate Europe and Asia, and also parts of Africa. It is resident in much of its range, but some populations from the more northern parts migrate southwards in autumn. A bird of wetland areas, it can be seen around lakes, rivers, ponds, marshes and on the sea coast. It feeds mostly on aquatic creatures which it catches after standing stationary beside or in the water, or stalking its prey through the shallows.

Standing up to 1 metre (3 ft 3 in) tall, adults weigh from 1 to 2 kg (2 to 4 lb). They have a white head and neck with a broad black stripe that extends from the eye to the black crest. The body and wings are grey above and the underparts are greyish-white, with some black on the flanks. The long, sharply pointed beak is pinkish-yellow and the legs are brown.

The birds breed colonially in spring in heronries, usually building their nests high in trees. A clutch of usually three to five bluish-green eggs is laid. Both birds incubate the eggs for around 25 days, and then both feed the chicks, which fledge when 7-8 weeks old. Many juveniles do not survive their first winter, but if they do, they can expect to live for about 5 years.

1-3-2017 MONTE CORONA, VALENCIA - EUROPEAN ROBIN (Erithacus rubecula)

The European robin (Erithacus rubecula), known simply as the robin or robin redbreast in Great Britain and Ireland, is a small insectivorous passerine bird, a member of the chat subfamily of the Old World flycatcher family. It is a plucky little bird, with a length of about 12.5–14.0 cm and a weight of 16–22 g. Both sexes are similarly adorned with an orange breast and face, lined with grey, brown upper-parts, and a whitish belly.

Adult robins can be identified by their orange breast and face, bordered by a bluish-grey on the sides of the neck and chest. The upperparts are brownish, or olive-tinged in British birds, and the belly is whitish. The bill and eyes are black. Juvenile robins are distinguishable by their spotted brown and white plumage, with patches of orange gradually appearing as they mature.

The European robin is a bird of diverse habitats, found in woodlands, gardens, and parks across its range. It is particularly associated with areas where the soil is dug or disturbed, allowing it easy access to its invertebrate prey.

This bird has a wide distribution across Europe, extending east to Western Siberia and south to North Africa. It is sedentary in most of its range except the far north, where it is migratory.

26-2-2017 PEGO MARJAL, ALICANTE - WHITE WAGTAIL (Motacilla alba)

The White wagtail (Motacilla alba) is a small insectivorous bird of the open country, often near habitation and water. It prefers bare areas for feeding, where it can see and pursue its prey. In urban areas, it has adapted to foraging on paved areas such as car parks. It is the national bird of Latvia and has been featured on the stamps of several countries.

The White wagtail is a slender bird with the characteristic long, constantly wagging tail of its genus. There are a number of other subspecies, some of which may have arisen because of partial geographical isolation, such as the resident British and Irish form, the pied wagtail M. a. yarrellii, which now also breeds in adjacent areas of the neighbouring European mainland. The Pied wagtail exchanges the grey colour of the nominate form with black (or very dark grey in females), but is otherwise identical in its behaviour. Other subspecies, the validity of some of which is questionable, differ in the colour of the wings, back, and head, or other features. Some rraces show sexual dimorphism during the breeding season. As many as six subspecies may be present in the wintering ground in India or Southeast Asia and here they can be difficult to distinguish.

White wagtails breed throughout Eurasia, only being absent in the Arctic. They also breed in the mountains of Morocco and western Alaska. These birds are residents in the milder parts of their range such as western Europe and the Mediterranean, but migratory in much of the rest of their range. Northern European breeders winter around the Mediterranean and in tropical and subtropical Africa, and Asiatic birds move to the Middle East, India, and Southeast Asia. Birds from the North American population also winter in tropical Asia. White wagtails occupy a wide range of habitats but are absent from deserts. They inhabit grasslands, seashores, rocky shorelines, sand beaches, tidepools, rivers, lakeshores, farmland, gardens, and parks. They are also often found in towns and villages. 

26-2-2017 PEGO MARJAL, ALICANTE - EUROPEAN SERIN (MALE) (Serinus serinus)

The European serin, or simply the serin (Serinus serinus), is a diminutive member of the finch family, Fringillidae. This sprightly bird is the smallest within its family, closely related to the Atlantic canary. It is characterized by its short tail and a length that spans a mere 11 to 12 centimeters. The serin's plumage is a tapestry of nature's palette, with upper parts dappled in dark-streaked greyish green and a conspicuous yellow rump. The underparts are a canvas of yellow breast and white belly, both adorned with heavy streaks.

When attempting to identify the European serin, look for the male's radiant yellow face and breast, which stand out against the greenish backdrop of its feathers. The male also boasts yellow wing bars and yellow tail sides, which can be quite helpful in distinguishing it from similar species. Both sexes share a buzzing trill of a song that resonates through their Mediterranean habitats.

The European serin is partial to open woodland and cultivated areas, often with a sprinkling of conifers. These environments provide the perfect backdrop for breeding and foraging.

This species has a breeding range that extends across southern and central Europe and into North Africa. Populations along the southern and Atlantic coasts tend to be resident, while those in the north are migratory, seeking warmer climates in southern Europe during the winter months.

Outside of the breeding season, the European serin is a sociable creature, forming flocks that may sometimes mingle with other finch species. It is an active and often conspicuous bird, its presence easily announced by its distinctive trill.

The serin's song is a distinctive buzzing trill, a sound that becomes part of the ambient music in regions where these birds are common.

The European serin weaves its nest within the shelter of a shrub or tree, where it lays a clutch of 3 to 5 eggs. The chosen breeding habitats are often areas of open woodland and cultivation, with a preference for some conifers.

The diet of the European serin is predominantly seeds, but it does not shy away from including insects during the breeding season, providing essential protein for its young.

The IUCN Red List categorizes the European serin as Least Concern, indicating that, for now, this species does not face any imminent threats to its survival.

This bird has a wide distribution across Europe, extending east to Western Siberia and south to North Africa. It is sedentary in most of its range except the far north, where it is migratory.

The robin is diurnal and is known for its boldness in human presence, often seen investigating gardeners at work. It is territorial, with males known to fiercely defend their territory. The robin's diet is primarily composed of insects and worms, but it will also consume berries and fruit, especially in autumn and winter.

The robin's song is a delightful fluting warble, more plaintive during the winter months. Both sexes sing, with the male's song typically starting before dawn and ending after dusk. Urban robins may sing at night, possibly to avoid noise pollution during the day.

Robins are versatile in their choice of nesting sites, often opting for unusual locations such as nooks in machinery or even discarded clothing. They typically lay two or three clutches of eggs per season, with the eggs being cream, buff, or white and speckled with reddish-brown.

The European robin is unique among the Erithacus genus, with its closest relatives being the Japanese robin and the Ryukyu robin, which are now placed in a different genus.

Robins primarily feed on insects, spiders, and worms. During colder months, their diet is supplemented with berries and fruit. They are also known to visit bird tables for seed mixtures and suet.

The European robin is classified as Least Concern by the IUCN, with a stable and possibly increasing population. It does not face any significant threats that would warrant concern for its long-term survival.

26-2-2017 PEGO MARJAL, ALICANTE - 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.

26-2-2017 ADOR CAMPO, 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.

26-2-2017 BARRACK PALMA DE GANDIA, VALENCIA - COMMON CHIFFCHAFF (Phylloscopus collybita)

The Common Chiffchaff, Phylloscopus collybita, is a diminutive and sprightly leaf warbler known for its distinctive, onomatopoeic song. This small, migratory passerine is characterized by its greenish-brown upperparts and off-white underparts, with a weight ranging from 6 to 8 grams and a length of 10-12 centimeters.

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.

The male Common Chiffchaff is fiercely territorial during the breeding season, defending its core territory against rivals. It exhibits a fearless nature, even attacking predators that threaten its nest. Outside the breeding season, these birds may form small flocks with other warblers.

26-2-2017 MONTE CORONA, VALENCIA - EUROPEAN ROBIN (Erithacus rubecula)

The UK's favourite bird. Thanks to its bright red breast, it's familiar throughout the year and especially at Christmas. Males and females look identical, young birds have no red breast and are spotted with golden brown. Robins sing nearly all year round and despite their cute appearance, they are aggressively territorial and are quick to drive away intruders. They will sing at night next to street lights.

In winter, the robin puffs up its plumage to insulate its body against cold winds.

The European robin is perhaps the best known of all British birds.  It is a common visitor to gardens and once attracted to food put out on a bird table, it will return to it all winter through.

Every continent has its own robins, but only the Japanese and Ryukyu robins are closely related.

Features of the robin include its distinctive red breast and face, grey under parts, brown head, wings and tail.  Their flight is distinguishable by rapid wing beats for short, fast flight.

26-2-2017 MONTE CORONA, VALENCIA - WHITE WAGTAIL (Motacilla alba)

The White Wagtail is mostly an aquatic bird, but this species can be common in various types of habitats, as well near water to hunt as in urban parks and cities for roosting in trees.

The adult male of nominate race in breeding plumage has black and white head. The forehead, lores, cheeks, ear-coverts and head sides are white. Chin and throat are black, as the rear crown, the nape and the hind neck.

On the upperparts, mantle and scapulars to uppertail-coverts are grey. The upperwing shows greyish, black and white pattern, forming two white wingbars.  

The long tail shows black central pair of rectrices finely edged white. The outer two pairs are white. The tail is similar in length to the wings.  

On the underparts, following chin and throat, breast is black too and contrasts strongly with the white belly. Breast sides and flanks are washed pale grey.

The pointed bill is black. The eyes are blackish-brown. Legs and feet are black.

The female in breeding plumage has slightly duller head pattern, with sometimes some grey on crown and nape. There often are some pale spots on the black throat.

In non-breeding plumage, both sexes have olive-grey wash on both crown and nape. Chin, throat and breast are white with some black mottling.

22-3-2017 PEGO MARJAL, ALICANTE - COMMON CRANE (Grus grus)

The common crane, known scientifically as Grus grus and also referred to as the Eurasian crane, is a majestic bird belonging to the Gruidae family. This medium-sized crane is the only species commonly found in Europe, apart from the demoiselle crane and the Siberian crane, which are primarily seen in the continent's far eastern regions. The common crane is distinguished by its slate-grey plumage, blackish forehead, lores, and a striking bare red crown. A white streak extends from behind the eyes to the upper back, setting it apart from similar species.

Adult common cranes measure between 100–130 cm in length and boast a wingspan of 180–240 cm. Their body weight ranges from 3 to 6.1 kg, with males typically larger and heavier than females. The species exhibits sexual size dimorphism, most notably in weight and wing length. Juveniles can be identified by their yellowish-brown feather tips and lack of adult coloration, including the drooping wing feathers and bright neck pattern.

Common cranes favor wetlands as their preferred habitats, thriving in boreal and taiga forests, mixed forests, and treeless moors. They breed in environments that offer peace and minimal human disturbance, often near small lakes or pools.

The common crane's breeding range spans Europe and the Palearctic to Siberia, with significant populations in Russia, Finland, and Sweden. It migrates to wintering grounds in Portugal, Spain, northern Africa, and parts of Asia, including China and the Indian subcontinent.

These cranes are social birds outside the breeding season, forming flocks that can number up to 400 individuals. They engage in a spectacular dancing display, which includes leaping with wings uplifted. This behavior serves complex social functions and can occur at any time of year.

The common crane's call is a loud, trumpeting sound that can be heard from great distances. It is typically given in flight and during their display dances.

Common cranes are monogamous and may form pair bonds that last for many years. They engage in elaborate courtship rituals each spring, which include synchronized calls and dances. Nests are built in or near shallow water, and the clutch usually contains two eggs. Both parents are fiercely protective of their nest and young.

The common crane can be confused with the hooded and black-necked cranes of Asia, but its unique coloration and display behaviors are distinguishing features.

Omnivorous in nature, common cranes feed on a variety of plant and animal matter. Their diet includes roots, seeds, berries, insects, and small vertebrates. They forage in small groups, benefiting farmers by consuming waste grain in fields.

The common crane is classified as Least Concern by the IUCN, with a global population estimated at around 500,000 individuals. However, habitat loss and degradation pose significant threats to the species, leading to local extinctions and conservation efforts, such as reintroduction projects in the United Kingdom.

22-3-2017 PEGO MARJAL, ALICANTE - CATTLE EGRET (Bubulcus 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.

22-3-2017 PEGO MARJAL, ALICANTE - 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 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.
