23-12-2018 ADOR CAMPO, VALENCIA - EUROPEAN ROBIN (Erithacus rubecula)


23-12-2018 ADOR CAMPO, VALENCIA - LITTLE OWL (Athene noctua)


The Little Owl, Athene noctua, is a diminutive yet distinctive bird, often associated with the goddess Athena in Greek mythology and Minerva in Roman lore. This bird is characterized by a flat-topped head, a robust, compact body, and a relatively short tail. Its plumage is a mottled greyish-brown, adorned with white spots, streaks, and bars, giving it a cryptic appearance. Both sexes are similar in size, measuring approximately 22 cm in length with a wingspan of 56 cm, and weighing around 180 grams.

The Little Owl possesses a large head, elongated legs, and striking yellow eyes. Its white "eyebrows" lend it a somewhat stern expression. Juvenile birds are somewhat duller than adults and lack the white crown spots. The species is known for its woodpecker-like bounding flight. During the moult, which occurs from July to November, males begin shedding feathers before females.

This owl favors open countryside and thrives in a variety of habitats, including agricultural lands with hedgerows and trees, orchards, woodland edges, parks, gardens, steppes, and semi-deserts. It can also be found in treeless areas such as dunes, and near human-made structures like ruins and quarries.


The Little Owl's range spans much of temperate and warmer parts of Europe, the Palearctic east to Korea, and North Africa. It has been introduced to Britain and the South Island of New Zealand, where it has established populations.

The Little Owl is known for its territorial nature, with males defending their territories from intruders. It is partly diurnal and can often be seen perched in prominent positions during the day. Its diet consists of insects, earthworms, other invertebrates, and small vertebrates. The owl is adept at swooping down on prey from its perch and is known to cache surplus food.

The Little Owl's call is a querulous "kiew, kiew," and it also produces various whistling or trilling sounds. During the breeding season, it may emit more modulated calls, and pairs can engage in duets. Near the nest, the owl may make yelping, chattering, or barking noises.


Breeding season sees increased vocal activity at night in late spring. Nests are located in a variety of places, including tree holes, cliffs, and old buildings. The female lays a clutch of about four eggs, which she incubates. The male provides food during this period, and both parents feed the chicks once hatched. Young owls fledge at about seven weeks of age.

The Little Owl can be confused with other small owl species, but its distinctive "eyebrows," yellow eyes, and flight pattern help differentiate it.

The Little Owl's diet is diverse, including mammals like mice and voles, birds, and a wide range of insects. It hunts both on the ground and in flight, and food caching behavior has been observed.

The International Union for Conservation of Nature (IUCN) has classified the Little Owl as "Least Concern" due to its extensive range and large overall population, which appears to be stable.

23-12-2018 LA FONT EN CARROS, 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.


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.

19-12-2018 CATARROJA, VALENCIA - GLOSSY IBIS (Plegadis falcinellus)


The glossy ibis (Plegadis falcinellus) is a water bird in the order Pelecaniformes and the ibis and spoonbill family Threskiornithidae. The scientific name derives from Ancient Greek plegados and Latin, falcis, both meaning "sickle" and referring to the distinctive shape of the bill.

This is the most widespread ibis species, breeding in scattered sites in warm regions of Europe, Asia, Africa, Australia, and the Atlantic and Caribbean regions of the Americas. It is thought to have originated in the Old World and spread naturally from Africa to northern South America in the 19th century, from where it spread to North America. The glossy ibis was first documented in the New World in 1817 (New Jersey). Audubon saw the species just once in Florida in 1832. It expanded its range substantially northwards in the 1940s and to the west in the 1980s. This species is migratory; most European birds winter in Africa, and in North America birds from north of the Carolinas winter farther south. Though generally suspected to be a migratory species in India, the glossy ibis is resident in western India. Birds from other populations may disperse widely outside the breeding season. It is increasing in Europe. It disappeared as a regular breeding bird in Spain in the early 20th century, but re-established itself in 1993 and has since rapidly increased with thousands of pairs in several colonies. It has also established rapidly increasing breeding colonies in France, a country with very few breeding records before the 2000s. An increasing number of non-breeding visitors are seen in northwestern Europe, a region where glossy ibis records historically were very rare. For example, there appears to be a growing trend for birds to winter in Britain and Ireland, with at least 22 sightings in 2010. In 2014, a pair attempted to breed in Lincolnshire, the first such attempt in Britain. The first successful breeding in Britain was a pair which fledged one young in Cambridgeshire in 2022. A few birds now spend most summers in Ireland, but there is no present evidence of breeding. In New Zealand, a few birds arrive there annually, mostly in the month of July; recently a pair bred amongst a colony of royal spoonbill.


Glossy ibises undertake dispersal movements after breeding and are highly nomadic. The more northerly populations are fully migratory and travel on a broad front, for example across the Sahara Desert. Glossy ibis ringed in the Black Sea seem to prefer the Sahel and West Africa to winter, those ringed in the Caspian Sea have been found to move to East Africa, the Arabian peninsula and as far east as Pakistan and India. Numbers of glossy ibis in western India varied dramatically seasonally with the highest numbers being seen in the winter and summers, and drastically declining in the monsoon likely indicating local movements to a suitable area to breed. Populations in temperate regions breed during the local spring, while tropical populations nest to coincide with the rainy season. Nesting is often in mixed-species colonies. When not nesting, flocks of over 100 individuals may occur on migration, and during the winter or dry seasons the species is usually found foraging in small flocks. Glossy ibises often roost communally at night in large flocks, with other species, occasionally in trees which can be some distance from wetland feeding areas.

19-12-2018 CATARROJA, VALENCIA - MEDITERRANEAN MANTIS (FEMALE) (Iris oratoria)



19-12-2018 CATARROJA, VALENCIA - GIANT HOUSE SPIDER (Eratigena atrica)


The giant house spider has been treated as either one species, under the name Eratigena atrica, or as three species, E. atrica, E. duellica and E. saeva. As of April 2020, the three species view was accepted by the World Spider Catalog. They are among the largest spiders of Central and Northern Europe. They were previously placed in the genus Tegenaria. In 2013, they were moved to the new genus Eratigena as the single species Eratigena atrica. In 2018, the three separate species were restored. The bite of these species does not pose a threat to humans or pets, and they are generally reluctant to bite, preferring instead to hide or escape.

The two sexes do not differ in coloration or markings. Its coloration is mainly dark brown. On its sternum is a lighter marking, with three light spots on each side that form an arrow-like shape pointing toward the head of the spider. The opisthosoma features a lighter middle line with six "spots" on each side. The giant house spider has the same coloration as the domestic house spider, Tegenaria domestica; it has earthy tones of brown and muddy red or yellow. They also have conspicuously hairy legs, palps, and abdomen. The female body-size can reach 18.5 millimeters (0.73 in) in length, with males having a slightly smaller body at around 12 to 15 millimeters (0.47 to 0.59 in) in length. The female leg-span is typically around 45 millimeters (1.8 in). The leg span of the male is highly variable, with spans between 25 and 75 millimeters (0.98 and 2.95 in) being common.

Its eight eyes are of equal size and are arranged in two rows. As the eyes contain fewer than 400 visual cells, E. atrica can probably only distinguish light and dark.

19-12-2018 CATARROJA, VALENCIA - 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.

The Glossy Ibis is classified as Least Concern by the IUCN. However, it faces threats from habitat degradation and loss due to drainage, salinity changes, groundwater extraction, and invasive plant species. It is protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA).

19-12-2018 CATARROJA, 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 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.

Immature has brownish-grey head with dusky malar stripe. Chin and throat are greyish-white with narrow grey-brown gorget. The underparts are greyish-white with buff tinge.

There are several subspecies which differ in colour of upperparts and in head pattern. Some of them are now full species.


The White Wagtail in flight utters a high-pitched “tslee-wee” or “tslee-vit” often repeated and some variants. We can also hear a short “tsit”, a harsh “chizzick” and a more slurred “tzwerp”.
The song is a series of twittering phrases interspersed with call notes.
At roost, they utter twittering noises.

The White Wagtail frequents a wide variety of open wet and dry habitats such as seashores, upland rivers and slow-moving lowland rivers, and lakeshores. But this species is also found in cultivated areas, urban parks and gardens, and in the vicinity of towns and cities. This bird is common in gardens around human habitations.

During migrations or winter, it also frequents various wet areas such as edges of reservoirs, lakes and ponds, ricefields and irrigated fields, towns and cities, campsites and beaches.
This species can breed from lowlands to high mountains (up to 5000 metres of elevation in the Himalayas).

The White Wagtail breeds in most parts of Europe and Asia, and some regions of North Africa.


The White Wagtail feeds on numerous small aquatic and terrestrial invertebrates. It catches insects on the ground after a short pursuit, but also on the wing. It pursues the prey with rapid undulating flight, or by short hovering before to hawk it. On the ground, this bird hunts by walking and exploiting all types of surfaces, from roads to roofs and other open areas.
It can pick at preys by running and picking to capture them. It also jumps into the air to hawk a flying insect.

But this aquatic species also forages in shallow water where it catches invertebrates from the surface or in the mud. It also hovers over water or vegetation.
On seacoasts, it forages among the seaweeds along the tideline. When foraging in cultivated areas, it follows the ploughs.

The White Wagtail can be seen alone or in pairs, but during the migration, the birds often gather in loose flocks, as at abundant food sources and at roost.
They roost communally in trees or reedbeds, sometimes inside factories in urban areas.

During the breeding season, the White Wagtail is very territorial and can become very aggressive towards other birds and intruders. They can chase larger birds such as Dippers and shorebirds from the breeding territory. During these threat displays, the plumage is usually puffed up and the tail is raised. The black breast is exposed towards the intruder.

19-12-2018 CATARROJA, 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.

19-12-2018 CATARROJA, VALENCIA - BLACK HEADED GULL (Chroicocephalus ridibundus)



The black-headed gull (Chroicocephalus ridibundus) is a small, nimble gull with a wingspan ranging from 94 to 110 cm and a body length of 37 to 44 cm. It weighs between 190 and 400 grams. Despite its name, the adult's summer plumage features a chocolate-brown head, which can appear black from a distance. The body is pale grey, and the primary wing feathers are tipped with black. The bill and legs are a striking red. In winter, the brown head is replaced by a white one with dark spots. Juveniles are mottled with brown spots and have a black band on the tail. There is no sexual dimorphism in plumage.

In flight, the white leading edge of the wing is a distinctive field mark. The summer adult's brown head, red bill, and legs are key identifiers, while the winter plumage features two dark spots on the head. Juveniles can be recognized by their mottled brown pattern and black tail band.

This species nests in colonies on the ground in large reed beds, marshes, or islands within lakes. It is not pelagic and is seldom seen far from coasts.

The black-headed gull breeds across much of the Palearctic, including Europe and coastal eastern Canada. It is migratory, wintering further south, but some remain in the milder westernmost areas of Europe. It is also present in northeastern North America and occasionally seen as far south as Virginia and some Caribbean islands.


Highly gregarious in winter, the black-headed gull is an opportunistic feeder, consuming a wide range of food from insects to carrion. It is known for its "kree-ar" call and displays various behaviors such as eggshell removal from the nest, which is believed to reduce predation risk.

The black-headed gull is a vocal species, particularly in colonies. Its call is a familiar "kree-ar," and its scientific name suggests a laughing sound.

This gull takes two years to reach maturity. First-year birds can be distinguished by a black terminal tail band and a less developed dark hood in summer. Breeding occurs in colonies, and the species is known for its complex social behaviors, including begging coordination between siblings and conspecific brood parasitism.


The black-headed gull can be confused with the similar-looking Bonaparte's Gull in North America.

The diet includes insects, fish, seeds, worms, scraps, carrion, and invertebrates in ploughed fields. It feeds in towns and agricultural areas with equal relish.

The black-headed gull is listed as Least Concern on the IUCN Red List, indicating it is not currently at significant risk of widespread decline.

Individuals synchronize their vigilance activities with nearby conspecifics, depending on the distance between them.

19-12-2018 CATARROJA, 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.

19-12-2018 CATARROJA, VALENCIA - WESTERN CATTLE EGRET (MALE) (Bubulcus 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.

19-12-2018 CATARROJA, VALENCIA - WHITE WAGTAIL (Motacilla alba)


The White Wagtail (Motacilla alba) is a small, elegant passerine bird, a member of the family Motacillidae, which includes pipits and longclaws. This slender bird measures between 16.5 to 19 cm in length, with East Asian subspecies reaching up to 21 cm. It is characterized by its long, constantly wagging tail, a behavior that has become synonymous with the genus. Weighing an average of 25 g, the White Wagtail can live up to 12 years in the wild.

Adult White Wagtails exhibit a distinctive plumage with a combination of grey, black, and white. The bird's upper parts are generally grey, with a white face, belly, and breast. Males during the breeding season may show a darker back, and the species is known for its sharp, brisk call and more melodious song during courtship.


The White Wagtail is commonly found in open country, often in close proximity to human habitation and water sources. It shows a preference for bare areas which facilitate the sighting and pursuit of prey. This bird has adapted well to urban environments, utilizing paved areas such as parking lots for foraging.


This species has a vast breeding range across Europe, the Asian Palearctic, parts of North Africa, and has a presence in Alaska. It is a migratory bird, with populations moving to Africa and parts of Asia during the winter. In Great Britain and Ireland, the darker subspecies known as the Pied Wagtail is more prevalent.

The White Wagtail is known for its perpetual tail wagging, a behavior that remains somewhat enigmatic but is thought to be a signal of vigilance to predators. It is a monogamous bird that defends its breeding territory with determination.

The call of the White Wagtail is a sharp "chisick," softer than that of the Pied Wagtail. Its song is more structured and is used by males to attract females rather than to mark territory.

White Wagtails are monogamous breeders, with both sexes contributing to nest building. The nest is often placed in crevices or holes near water or in human-made structures. The species lays three to eight cream-colored, speckled eggs, which both parents incubate. Chicks fledge after 12 to 15 days and continue to be fed for a week thereafter.

19-12-2018 CATARROJA, VALENCIA - EUROPEAN GOLDFINCH (Carduelis carduelis)


The European goldfinch, or simply goldfinch (Carduelis carduelis), is a small, vibrant passerine bird belonging to the finch family. This charming avian species is adorned with a striking red face, encircled by black markings near the eyes, and a black-and-white head. The back and flanks exhibit a warm buff or chestnut brown, while the wings are black with a prominent yellow bar. The tail is black, and the rump is a contrasting white. Males and females are similar in appearance, though the male boasts a slightly more extensive red mask.

Upon closer inspection, one can discern the male goldfinch by its larger, more vivid red mask that extends just beyond the eye. The female's red face does not reach past the eye, and her shoulder feathers are brown, as opposed to the male's black. The bill is ivory-colored, long, and pointed, and the tail is forked. Juveniles can be identified by their plain heads and greyer backs, but the yellow wing stripe is a clear indicator of their species.

The European goldfinch favors open, partially wooded lowlands and is a resident in the milder western parts of its range. In colder regions, it migrates to escape the harsh weather.

19-12-2018 CATARROJA, VALENCIA - BLACK HEADED GULL (Chroicocephalus ridibundus)

21-12-2018 MONTE CORONA, VALENCIA - PLANTAIN FAMILY (Antirrhinum controversum)


Very close to Antirrhinum litigiosum and Antirrhinum tortuosum, it differs from them by having lanceolate, acute bracts, lanceolate sepals, subacute to acuminate, recurved. While Antirrhinum litigiosum and Antirrhinum tortuosum have ovate or ovate-lanceolate, obtuse or acute bracts, ovate, obtuse, non-recurved sepals.

Traditionally this species is better known under the epithet of Antirrhinum barrelieri. However, Antirrhinum barrelieri was described from plants cultivated in the Botanical Garden of Angers, according to species originating from seeds from Tortosa (Tarragona). The ancient authors did not appreciate differences between the plants of the E and NE of the Peninsula with those of the SE. However, the most recent studies of the genus do differentiate them, calling those from the SE Antirrhinum barrelieri, a name that could only be assigned to those from the E and NE.

Carlos Pau was able to interpret this confusing situation and proposed the current names of Antirrhinum controversum for the species from the SE Iberian Peninsula and Antirrhinum litigiosum for those from the E and NE Iberian Peninsula


Flower colour: Pale pink.

Flowering: February to November.

Ecology: Ruderal and rock-cut vegetation. It grows in fissures and rocky landings, on walls, at the edge of roads and in stony areas. Indifferent to the substrate, it has a marked preference for limestone. It grows in places with disturbed, rocky or stony soils, slightly nitrified, preferably in sunny to semi-shaded areas and in areas with mild winters.

Altitudinal range: 10 – 1,600 m.

Distribution: Iberian endemism. Dispersed throughout the southeastern third of the Iberian Peninsula.

19-12-2018 CATARROJA, VALENCIA - COMMON CHAFFINCH (FEMALE) (Fringilla coelebs)


The Eurasian chaffinch, or simply the chaffinch (Fringilla coelebs), presents a striking dichotomy in plumage between the sexes. The male is resplendent with a blue-grey cap and rust-red underparts, while the female's attire is more subdued, though both genders boast two white wing bars and white sides to their tails. The male's robust voice is a herald of spring, as he sings from exposed perches to court a mate.

To identify the male chaffinch, look for the black forehead, blue-grey crown, and rust-red breast, which fades to a pale creamy-pink on the belly. The wings feature a white panel on the coverts and a buff-white bar on the secondaries and inner primaries. Females and juveniles are more muted with grey-brown shades above and paler below, but retain the distinctive wing markings.

Chaffinches favor wooded environments, thriving in areas where the July isotherm ranges from 12 to 30°C. They are adaptable, however, and can be found in a variety of forested landscapes across their range.

This small passerine bird is widespread across Europe and parts of Asia, extending to Siberia. It is also an introduced species in some regions, such as New Zealand and South Africa.

Chaffinches are gregarious outside the breeding season, forming flocks in open countryside. They exhibit partial migration, with birds in colder regions moving south for the winter, while those in milder areas may remain sedentary.


The male chaffinch's song is a delightful mix of trills and chirps, with regional dialects adding to the chorus. Each male typically has a repertoire of two or three song types.

Monogamous by nature, chaffinches breed once they reach one year of age. The female meticulously constructs a nest in the fork of a tree, laying a clutch of 4-5 eggs that hatch in about 13 days. The fledglings take to the wing approximately 14 days later but continue to receive parental care for several weeks thereafter.

During the breeding season, chaffinches forage in trees for invertebrates, particularly caterpillars, to feed their young. Outside this period, their diet shifts to seeds and plant material found on the ground.

With its large numbers and expansive range, the Eurasian chaffinch is classified as of Least Concern by the International Union for Conservation of Nature. There is no evidence of significant population declines at present.

Chaffinches must be vigilant against a variety of predators, including crows and squirrels, which may prey upon their eggs and nestlings. They are also susceptible to parasites such as the protozoal Trichomonas gallinae and the Fringilla coelebs papillomavirus, which can cause tumors on their feet and legs.
