5-1-2025 PEGO MARJAL, VALENCIA - EUROPEAN STONECHAT (MALE) (Saxicola rubicola)

The European stonechat, Saxicola rubicola, is a small, charming passerine bird, once thought to be a member of the thrush family but now placed within the Old World flycatcher family, Muscicapidae. This species exhibits a striking sexual dimorphism, with males donning a black plumage with vibrant orange throats and females wearing a more subdued brown.

Males in their summer plumage are unmistakable with their black heads, orange throats, and white bellies. They also sport a distinctive white half-collar and small white patches on the wings and rump. Females, on the other hand, are predominantly brown with less pronounced white wing patches. Both sexes have notably short wings, which are shorter than those of their migratory relatives.

The European stonechat favors heathlands, coastal dunes, and open grasslands dotted with shrubs, brambles, and heather. These habitats provide the perfect backdrop for their active foraging and breeding behaviors.

This species is widely distributed across Europe, reaching as far east as Ukraine and the South Caucasus, and can also be found in parts of North Africa.

Stonechats are known for their lively presence, often perching conspicuously as they keep a vigilant eye on their surroundings. They exhibit a partial migratory pattern, with some populations moving southward to escape the colder winters.

The male stonechat's song is a delightful, high-pitched twitter, reminiscent of a dunnock's melody. Both sexes communicate with a distinctive call that evokes the sound of two stones being tapped together. 

5-1-2025 PEGO MARJAL, 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.

5-1-2025 PEGO MARJAL, VALENCIA - EURASIAN GREAT CORMORANT (Phalacrocorax carbo)

The great cormorant (Phalacrocorax carbo), a robust seabird, is cloaked in predominantly black plumage. It is a member of the cormorant family, with a widespread distribution. The species exhibits considerable size variation across its range, with males generally larger than females. Notable features include a longish tail and a distinctive yellow throat-patch. During the breeding season, adults boast white patches on their thighs and throat.

To identify the great cormorant, look for its large size, heavy build, and thick bill. It lacks a crest and its plumage does not have a green tinge, distinguishing it from the common shag. In North America, it is bulkier than the double-crested cormorant and has less yellow on the throat and bill. The white thigh patches are a key identifier.

Great cormorants are found in a variety of aquatic environments including seas, estuaries, freshwater lakes, and rivers. They often nest in colonies close to these water bodies.

This species has a broad distribution, breeding across the Old World, Australia, and the Atlantic coast of North America. Northern populations tend to migrate southward in winter, seeking coasts rich in fish.

Great cormorants are generally silent but may emit guttural noises at breeding colonies. They are known for their wing-drying posture, often seen with wings outstretched to dry after diving.

16-7-2024 ROTTERDAM ZOO, NETHERLANDS - RHINOCEROS IGUANA (Cyclura cornuta)

Aside from Hispaniola and its surrounding islands, the rhinoceros iguana was previously found on Navassa Island (with an endemic subspecies: C. c. onchiopsis), but was extirpated there.

Rhinoceros iguanas, like most members of Cyclura, are usually docile and well-tempered. As with many lizard species, “head-bobbing” is a commonly observed form of communication used by the rhinoceros iguana. Males, especially, appear to “nod” their heads toward one another as an assertion of dominance, or announcing their “ownership” of an area. It is oftentimes a warning to not come any closer, as well as to communicate (with females) their desire to mate. At times, this form of body language is directed at humans (by both wild and captive iguanas) as a warning, or as a sort of “greeting” to their human caretaker(s). The females (more or less) only nod their heads to ward off incessant advances from males, and female-to-female head bobbing is infrequent, though not nonexistent.

22-3-2017 TROGON LODGE, COSTA RICA - MOUNTAIN THRUSH (Turdus plebejus)

The Mountain Thrush, known scientifically as Turdus plebejus, is a robust member of the thrush family, Turdidae. This bird, once called the Mountain Robin, is a Central American native with a rather unassuming plumage. Adults are cloaked in a uniform dull olive-brown, with subtle white streaks gracing the throat. They measure between 23 to 26 centimeters in length and tip the scales at an average of 86 grams. The bill is a stark black, while the legs are a dark brown hue. Juveniles share a resemblance with adults but are distinguished by buff or orange streaks on their head and upperparts, and dark spotting on their underparts.

To identify the Mountain Thrush, look for its olive-brown plumage and faint white throat streaks. It can be confused with its relatives, the Sooty Thrush, which is darker with an orange bill, eye ring, and legs, and the Clay-colored Thrush, which is paler with a yellow bill.

4-1-2015 MONTE CORONA, VALENCIA - EURASIAN BLACKCAP (FEMALE) (Sylvia atricapilla)

The Eurasian blackcap, Sylvia atricapilla, is a common and widespread typical warbler known for its distinctive cap and melodious song. The species exhibits sexual dimorphism with males sporting a black cap and females a chestnut one. The upperparts are generally olive-grey, while the underparts are pale grey. This bird is small and agile, measuring around 13 cm in length with a wingspan of 7–8 cm.

Males can be identified by their black caps and light grey underparts, while females have a reddish-brown cap and a slightly browner hue to their grey upperparts. Juveniles resemble females but have a rufous tinge to their upperparts and a more olive tone on the breast and flanks. The blackcap's tail is dark grey with an olive edge to each feather, and it has a grey bill and legs with a reddish-brown iris.

The blackcap favors mature deciduous woodlands with a well-developed understory. It also occupies parks, large gardens, and overgrown hedges, provided there are tall trees for songposts and dense shrubs for nesting.

This warbler breeds across much of Europe, western Asia, and northwestern Africa. It is a partial migrant, with northern populations wintering in northwestern Europe, around the Mediterranean, and in tropical Africa. Some have adapted to wintering in British and Irish gardens.

Blackcaps are territorial during the breeding season, with males establishing and defending their territories through song and display. They are mainly monogamous and may raise one to two broods per season. The species is known for its leap-frog migration pattern, where northern populations migrate further south than those from the Mediterranean.

The male blackcap's song is a rich musical warble, often ending in a high-pitched crescendo. In isolated areas, a simpler song may be heard. Calls include a hard "tac-tac" and various squeaks and trills. The song is sometimes confused with that of the garden warbler but is slightly higher-pitched and more broken.

Blackcaps typically build a neat cup-shaped nest in brambles or scrub, laying a clutch of 4–6 buff eggs with grey and brown markings. Both parents incubate the eggs and care for the altricial chicks, which fledge in about 11–12 days.

The blackcap can be confused with other dark-headed Sylvia species, such as the Sardinian and Orphean warblers, but these have more extensive black on the head and are larger with white tail edges.

During the breeding season, blackcaps feed mainly on insects, switching to fruit in late summer. In winter, they consume small fruits and may rely on food provided in gardens, such as bread, fat, and peanuts.

Despite pressures from hunting in the Mediterranean and natural predation, the blackcap has been expanding its range for decades and is classified by the International Union for Conservation of Nature (IUCN) as Least Concern. Its population is estimated to be between 101 and 161 million individuals globally.

24-3-2017 RANCHO NATURALISTA, COSTA RICA - WHITE NECKED JACOBIN (MALE) (Florisuga mellivora)

The White-necked Jacobin, scientifically known as Florisuga mellivora, is a medium-sized hummingbird adorned with a striking plumage. The male is particularly distinctive, boasting a dark blue head and chest, contrasted by a pure white belly and tail, the latter tipped with black. A white band graces the nape, setting apart the blue head from the vibrant green back and elongated uppertail coverts. Females exhibit a more variable appearance, often showing green upperparts and a blue-green throat, with white "scales" and a white belly. Their tails are mostly green with a blue terminal band.

Males are unmistakable with their contrasting blue and white plumage. Females and immatures can be more challenging to identify due to their variability, but typically females have less white in the tail and a bronzy hue on the throat and chest.

3-1-2025 SOLLANA, ALBUFERA - EURASIAN HOOPOE (Upupa epops)

The Eurasian hoopoe (Upupa epops) is the most widespread species of the genus Upupa. It is a distinctive cinnamon coloured bird with black and white wings, a tall erectile crest, a broad white band across a black tail, and a long narrow downcurved bill. Its call is a soft "oop-oop-oop".

The Eurasian hoopoe is native to Europe, Asia and the northern half of Africa. It is migratory in the northern part of its range. Some ornithologists consider the African and Madagascar hoopoes its subspecies.

The Eurasian hoopoe was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae. He cited the earlier descriptions by the French naturalist Pierre Belon and by the Swiss naturalist Conrad Gessner, both of which had been published in 1555. Linnaeus placed the Eurasian hoopoe with the northern bald ibis and the red-billed chough in the genus Upupa and coined the binomial name Upupa epops. The specific epithet epops in the Ancient Greek word for a hoopoe.

The muscles of the head allow the hoopoe's bill to be opened when it is inserted into the ground.

The Eurasian hoopoe is a medium-sized bird, 25–32 cm (9.8–12.6 in) long, with a 44–48 cm (17–19 in) wingspan. It weighs 46–89 g (1.6–3.1 oz).[7] The species is highly distinctive, with a long, thin tapering bill that is black with a fawn base. The strengthened musculature of the head allows the bill to be opened when probing inside the soil. The hoopoe has broad and rounded wings capable of strong flight; these are larger in the northern migratory subspecies. The hoopoe has a characteristic undulating flight, which is like that of a giant butterfly, caused by the wings half closing at the end of each beat or short sequence of beats.[7] Adults may begin their moult after the breeding season and continue after they have migrated for the winter.

The call is typically a trisyllabic oop-oop-oop, which may give rise to its English and scientific names, although two and four syllables are also common. An alternative explanation of the English and scientific names is that they are derived from the French name for the bird, huppée, which means crested. In the Himalayas, the calls can be confused with that of the Himalayan cuckoo (Cuculus saturatus), although the cuckoo typically produces four notes. Other calls include rasping croaks, when alarmed, and hisses. Females produce a wheezy note during courtship feeding by the male.

3-1-2025 MUNTANYETA DEL SANS, ALBUFERA - GLOSSY IBIS (Plegadis falcinellus)

The Glossy Ibis, Plegadis falcinellus, is a wading bird of the family Threskiornithidae, known for its striking, sickle-shaped bill. This mid-sized ibis measures 48–66 cm in length, with a wingspan of 80–105 cm. Breeding adults boast reddish-brown bodies and iridescent bottle-green wings, while non-breeders and juveniles display a more subdued coloration. The species is characterized by a brownish bill, dark facial skin with blue-gray to cobalt blue borders, and red-brown legs. In flight, the ibis extends its neck and exhibits a graceful V formation.

When identifying the Glossy Ibis, look for its unique glossy feathers and the distinct shape of its bill. The bird's flight pattern is also a telltale sign, as it flies with its neck outstretched, unlike herons. Listen for its various croaks and grunts, particularly the hoarse grrrr sound during the breeding season.

The Glossy Ibis favors freshwater or brackish wetlands with tall, dense emergent vegetation such as reeds, papyrus, or rushes, and low trees or bushes. It can also be found in lagoons, floodplains, wet meadows, swamps, reservoirs, sewage ponds, rice paddies, and irrigated farmland. Coastal habitats like estuaries and salt marshes are less common for this species.

This ibis is the most widespread of its kind, breeding in warm regions across Europe, Asia, Africa, Australia, and the Americas. It is migratory, with European birds wintering in Africa and North American birds migrating southward. The species has been expanding its range, with increasing numbers in Europe and successful breeding in Britain as of 2022.

The Glossy Ibis is known for its nomadic tendencies and dispersal movements post-breeding. Northern populations are migratory, traversing vast distances such as the Sahara Desert. The species nests in mixed colonies and forms large flocks during migration and winter. It often roosts communally with other species, sometimes in trees far from feeding areas.

The Glossy Ibis is relatively quiet, but it does produce a range of vocalizations, including croaks and grunts. A distinctive hoarse grrrr can be heard during the breeding season.

Nesting occurs above water on platforms of twigs and vegetation, with both parents incubating the 3 to 4 eggs laid. Chicks leave the nest after about a week but are fed by parents for another 6 to 7 weeks, fledging around 28 days old.

The ibis's diet is seasonal and opportunistic, feeding on a variety of prey such as insects, annelids, molluscs, crustaceans, and occasionally fish, amphibians, lizards, small snakes, and nestling birds.

3-1-2025 MUNTANYETA DEL SANS, ALBUFERA - GREAT EGRET (Ardea alba)

The great egret, known scientifically as Ardea alba, is a majestic bird with a stately bearing and an impressive wingspan. This large egret is adorned with all-white plumage and can stand up to a meter tall. It is a cosmopolitan species, found across temperate and tropical regions worldwide.

To identify the great egret, look for its yellow bill and contrasting black legs and feet, which may vary slightly during the breeding season. During this time, the bill may darken, and the lower legs may lighten. The great egret also sports ornamental feathers on its back when in breeding plumage. Both sexes appear identical, and juveniles resemble nonbreeding adults. The great egret can be distinguished from the intermediate egret by the gape of its bill, which extends well beyond the back of the eye.

The great egret favors habitats close to water, such as large lakes with reed beds and other extensive wetlands. It nests in colonies, often at heights of 10 to 40 feet within trees.

This bird has a vast range, occurring worldwide in suitable habitats. It is particularly common across the Sun Belt of the United States and throughout the Neotropics.

The great egret is known for its slow, graceful flight with its neck retracted, a characteristic of herons and bitterns. It walks with its neck extended and wings held close. Generally silent, it may emit a low, hoarse croak when disturbed and a louder croaking at breeding colonies.

The great egret's vocalizations include a low croak when disturbed and various croaking and squawking sounds during the breeding season.

Breeding begins at 2-3 years of age with monogamous pairings. The male initiates nest building to attract a female. The nest is a sizable structure of sticks, lined with plant material. The species lays up to six bluish-green eggs, with both parents sharing incubation duties over 23-26 days. The young are fed by regurgitation and can fly within 6-7 weeks.

The great egret can be confused with the snowy egret, which is smaller with a black bill and yellow feet. In North America, it may also be mistaken for the white morph of the great blue heron, which is larger with a thicker bill.

The great egret's diet consists of fish, frogs, small mammals, reptiles, crustaceans, and insects. It typically forages in shallow water, standing still or slowly stalking its prey before impaling it with its sharp bill.

The great egret is listed as Least Concern by the IUCN. It has recovered from historical threats such as plume hunting and has adapted well to human presence. It is partially migratory, with some populations moving south during colder winters. The species is a symbol of conservation success and represents the National Audubon Society.

2-1-2025 POTRIES, VALENCIA - EURASIAN GREAT CORMORANT (Phalacrocorax carbo)

The great cormorant (Phalacrocorax carbo), a robust seabird, is cloaked in predominantly black plumage. It is a member of the cormorant family, with a widespread distribution. The species exhibits considerable size variation across its range, with males generally larger than females. Notable features include a longish tail and a distinctive yellow throat-patch. During the breeding season, adults boast white patches on their thighs and throat.

To identify the great cormorant, look for its large size, heavy build, and thick bill. It lacks a crest and its plumage does not have a green tinge, distinguishing it from the common shag. In North America, it is bulkier than the double-crested cormorant and has less yellow on the throat and bill. The white thigh patches are a key identifier.

Great cormorants are found in a variety of aquatic environments including seas, estuaries, freshwater lakes, and rivers. They often nest in colonies close to these water bodies.

This species has a broad distribution, breeding across the Old World, Australia, and the Atlantic coast of North America. Northern populations tend to migrate southward in winter, seeking coasts rich in fish.

Great cormorants are generally silent but may emit guttural noises at breeding colonies. They are known for their wing-drying posture, often seen with wings outstretched to dry after diving.

Mostly silent, the great cormorant vocalizes with guttural sounds in the vicinity of its breeding colonies.

Great cormorants typically nest in colonies near wetlands, rivers, or sheltered inshore waters, often returning to the same site annually. Their nests are constructed from sticks and can be located in trees, on cliff ledges, or on predator-free ground. They lay clutches of three to five pale blue or green eggs, which are incubated for about 28 to 31 days.

These birds are piscivorous, diving to catch fish such as wrasses, sand smelt, flathead, and common soles. They exhibit seasonal dietary shifts, preferring larger fish in colder temperatures. Their foraging efficiency is influenced by the size of the prey rather than the quantity.

The great cormorant is currently listed as Least Concern by the IUCN. Conservation efforts have led to a population rebound, with approximately 1.2 million birds in Europe alone. However, their increasing numbers have led to conflicts with fisheries due to predation on fish stocks.
