20-4-2018 OKAVANGO DELTA, BOTSWANA - VERVET MONKEY (Chlorocebus pygerythrus)

The Vervet monkey (Chlorocebus pygerythrus) is an Old World monkey native to Africa. The term "vervet" is also used to refer to all the members of the genus Chlorocebus. These adorable monkeys live in social groups and involve their communication and alarm calls, specifically in regard to kin and group recognition, and particular predator sightings.

The Vervet monkey is of medium to large size and has a black-tipped tail which is often longer than its body. Its fur is olive or gray, lighter on the underside. Its hands and feet are black, as are its ears and face. Its face has a white band above it, framed with white cheek tufts. Its arms and legs are long, about the same length as each other, to enable the monkey to walk with ease on all fours while on the ground, and this actually makes it quite speedy when running. The males tend to be bigger than the females.

31-12-2018 ADOR CAMPO, VALENCIA - MEDITERRANEAN PALE GLOW-WORM (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.

Fireflies are insects of the order Coleoptera, that is, of the group of beetles, and of the family Lampyridae, whose members have the remarkable characteristic of emitting light from the end of the abdomen by means of a chemical reaction. This luminescence that we see as small points of light on summer nights has the function of sexual attraction.

Nyctophila reichii, the Mediterranean firefly, is the most common species of firefly in the Bages region. Like other fireflies, Nyctophila reichii has a very marked sexual dimorphism; males and females would be considered different species if they were not seen copulating (in image 5a).

Adult females - in images 1 and 2 - are much larger than males; they have a large, swollen abdomen, about 4 cm long, light in colour with a pinkish tinge, short elytra that do not quite cover the abdomen, vestigial wings that are not used for flight and the pronotum forming a pinkish growth on the head. At night, females emit a cold, greenish light through the luminescent organs located on the ventral side of the last three abdominal segments, in order to attract a male. Females often adopt a contorted posture with the tip of the abdomen pointing upwards so that the luminescence is more visible.

The males - in images 3 and 4 - are much smaller, about 15-18 mm; they have the appearance of a typical beetle with well-developed elytra covering the abdomen and membranous wings that allow it to fly. The males of the Mediterranean firefly do not emit luminescence.

The larvae are dark and segmented, with the sides of the body red (photos 6, 7, 8 and 9). Both in the larval and adult stages, fireflies are specialized predators in the capture of snails and slugs. Image 6 shows a Nyctophila reichii larva devouring a dune snail ( Theba pisana ) .

30-12-2018 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.

Conservation Status

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.

30-12-2018 POTRIES, 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.

30-12-2018 POTRIES, 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.

27-12-2018 OLIVA MARJAL, 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.

The Willow Warbler and Bonelli's Warbler are similar species but can be differentiated by their longer primary projection, sleeker appearance, and different vocalizations. The Iberian Chiffchaff, once considered a subspecies, is now treated as a separate species due to differences in song, morphology, and genetics.

The Common Chiffchaff is insectivorous, feeding on a variety of insects and other small invertebrates. It is known to be an active forager, often seen flitting through foliage or hovering briefly to snatch prey.

The Common Chiffchaff is classified as "Least Concern" by the IUCN, with an extensive range and large population. While one subspecies is likely extinct, the overall species does not face significant threats at present, and populations in some areas are increasing.

27-12-2018 ADOR CAMPO, VALENCIA - EURASIAN KESTREL (Falco tinnunculus)

The common kestrel, Falco tinnunculus, is a bird of prey from the kestrel group within the falcon family Falconidae. It is also known as the European kestrel, Eurasian kestrel, or Old World kestrel. In the United Kingdom, it is often simply referred to as the "kestrel." This raptor is small compared to other birds of prey but larger than most songbirds, with long wings and a distinctive long tail.

Males and females exhibit sexual dimorphism in their plumage. The male has a blue-grey cap and tail with a black tip bordered by a narrow white rim. Its back is chestnut with black spots, and the underside is buff with black streaks. The female is larger and lacks the blue-grey coloring, having a brown back with black bars and a similar underside to the male. Both sexes have a prominent black malar stripe, bright yellow cere, feet, and eye-ring, with dark toenails, bill, and iris.

The common kestrel favors open habitats such as fields, heaths, shrubland, and marshland. It does not require woodland but needs alternative perching and nesting sites like rocks or buildings. It thrives in treeless steppes and can adapt to human settlements and various landscapes, from wetlands to arid savannas.

26-12-2018 CAMI LES FONTS OLIVA, VALENCIA - MALLARD (MALE) (Anas platyrhynchos)

The mallard is widely distributed across the Northern and Southern Hemispheres; in North America its range extends from southern and central Alaska to Mexico, the Hawaiian Islands, across the Palearctic, from Iceland and southern Greenland and parts of Morocco (North Africa) in the west, Scandinavia and Britain to the north, and to Siberia, Japan, and South Korea. Also in the east, it ranges to south-eastern and south-western Australia and New Zealand in the Southern hemisphere.: 505  It is strongly migratory in the northern parts of its breeding range, and winters farther south. For example, in North America, it winters south to the southern United States and northern Mexico, but also regularly strays into Central America and the Caribbean between September and May. A drake later named "Trevor" attracted media attention in 2018 when it turned up on the island of Niue, an atypical location for mallards.

The mallard inhabits a wide range of habitats and climates, from the Arctic tundra to subtropical regions. It is found in both fresh- and salt-water wetlands, including parks, small ponds, rivers, lakes and estuaries, as well as shallow inlets and open sea within sight of the coastline. Water depths of less than 0.9 metres (3.0 ft) are preferred, with birds avoiding areas more than a few metres deep. They are attracted to bodies of water with aquatic vegetation.

26-12-2018 OLIVA PUERTO, VALENCIA - YELLOW LEGGED GULL (JUVENILE) (Larus michahellis)

The Yellow-legged Gull (Larus michahellis) is a large, robust seabird with a commanding presence. Its size can be quite variable, with the smallest females being scarcely larger than a Common Gull, and the largest males approaching the heft of a Great Black-backed Gull. Adults typically exhibit a grey back, a shade lighter than that of the Lesser Black-backed Gull, and their heads are notably whiter in the autumn months. A distinctive feature is their yellow legs, which give this species its common name.

When observing the Yellow-legged Gull, look for the yellow legs that contrast with the grey back and the white head, which becomes even whiter during the autumn. The wing tips are black with limited white spots, and adults have a red spot on the bill. The eye is surrounded by a red ring. Juveniles can be identified by their paler head, rump, and underparts, dark bill and eyes, and a black band on the tail.

This gull favors a variety of coastal environments, often nesting on sea cliffs, islands, and occasionally on buildings within urban settings. It is also known to breed on trees in some regions.

The Yellow-legged Gull has a breeding range centered around the Mediterranean Sea, extending to the Atlantic islands and coasts as far north as Brittany and west to the Azores. Its presence is also noted on the western side of the Black Sea.

The species is known for its adaptability, with many individuals remaining in the same area year-round, while others migrate to milder regions of western Europe or head south to areas such as Senegal and the Red Sea. Post-breeding dispersal can lead to increased numbers in regions like southern England from July to October.

The vocalizations of the Yellow-legged Gull are characterized by a loud, laughing call that is deeper and more nasal than that of the Herring Gull.

Breeding typically occurs in colonies, with nests constructed on the ground or cliff ledges. The nests are mounds of vegetation, and the species is known for its vigorous defense of its eggs, usually numbering three. Incubation lasts for 27–31 days, and fledging occurs after 35–40 days.

An opportunistic forager, the Yellow-legged Gull is omnivorous, feeding on a wide range of items from rubbish tips to field prey, coastal offerings, and even other seabirds' catches. Remarkably, during periods of food scarcity, such as the lockdown in Italy in 2020, these gulls have been observed preying on larger animals like rats and rock doves.

The Yellow-legged Gull is currently listed as Least Concern on the IUCN Red List, indicating that it does not face any immediate threat of extinction.

26-12-2018 KIKO PORT OLIVA, VALENCIA - EURASIAN GREAT CORMORANT (Phalacrocorax carbo)

The great cormorant is a large black bird, but there is a wide variation in size in the species' wide range. Weight is reported to vary from 1.5 kg (3 lb 5 oz) to 5.3 kg (11 lb 11 oz). Males are typically larger and heavier than females, with the nominate race (P. c. carbo) averaging about 10% larger in linear measurements than the smallest race in Europe (P. c. sinensis). The lightest average weights cited are in Germany (P. c. sinensis), where 36 males averaged 2.28 kg (5 lb 1⁄2 oz) and 17 females averaged 1.94 kg (4 lb 4+1⁄2 oz). The highest come from Prince Edward Island in Canada (P. c. carbo), where 11 males averaged 3.68 kg (8 lb 2 oz) and 11 females averaged 2.94 kg (6 lb 7+1⁄2 oz). Length can vary from 70 to 102 cm (27+1⁄2 to 40 in) and wingspan from 121 to 160 cm (47+1⁄2 to 63 in). They are tied as the second largest extant species of cormorant after the flightless cormorant, with the Japanese cormorant averaging at a similar size. In bulk if not in linear dimensions, the blue-eyed shag species complex of the Southern Oceans are scarcely smaller at average. It has a longish tail and yellow throat-patch. Adults have white patches on the thighs and on the throat in the breeding season. In European waters it can be distinguished from the common shag by its larger size, heavier build, thicker bill, lack of a crest and plumage without any green tinge. In eastern North America, it is similarly larger and bulkier than double-crested cormorant, and the latter species has more yellow on the throat and bill and lack the white thigh patches frequently seen on great cormorants. Great cormorants are mostly silent, but they make various guttural noises at their breeding colonies.

26-12-2018 OLIVA MARJAL, 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 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.

26-12-2018 CAMI LES FONTS OLIVA, VALENCIA - GREYLAG GOOSE (Anser anser)

The Greylag Goose (Anser anser) is a large and robust member of the waterfowl family Anatidae, easily recognized by its mottled and barred grey and white plumage. It boasts an orange beak, pink legs, and a sizeable stature, measuring between 74 and 91 centimeters in length and weighing an average of 3.3 kilograms. This species is the progenitor of most domestic goose breeds and exhibits a wide distribution across Europe and Asia.

Adult Greylag Geese have a rotund body, a thick and long neck, and a large head and bill. Their legs and feet are pink, and their bill is orange or pink with a white or brown nail. The wingspan ranges from 147 to 180 centimeters. Males are typically larger than females, and the eastern subspecies rubirostris is larger than the nominate subspecies. The plumage is greyish brown with a darker head and paler underparts, with black spotting that varies among individuals. Juveniles can be identified by their lack of black speckling and greyish legs.

Greylag Geese breed in a variety of wetland habitats, including moorlands, marshes, lakes, and coastal islands. They prefer areas with dense vegetation for cover. In winter, they occupy semi-aquatic habitats such as estuaries, marshes, flooded fields, and agricultural lands.

The Greylag Goose has a Palearctic distribution, with the western subspecies breeding from Iceland to central Europe and the eastern subspecies from Romania to northeastern China. Northern populations often migrate southwards to spend the winter in warmer regions, while many populations are resident year-round.

Greylag Geese are known for their lifelong monogamous pair bonds. They are gregarious and form flocks, which provides safety in numbers. Family groups stay together, migrating southwards in autumn and separating the following year. They are herbivorous, feeding mainly on grasses, and can cause damage to agricultural crops.

26-12-2018 OLIVA PUERTO, 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.

26-12-2018 CAMI LES FONTS OLIVA, VALENCIA - MALLARD (FEMALE) (Anas platyrhynchos)

The mallard (/ˈmælɑːrd, ˈmælərd/) or wild duck (Anas platyrhynchos) is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa. It has been introduced to New Zealand, Australia, Peru, Brazil, Uruguay, Argentina, Chile, Colombia, the Falkland Islands, and South Africa. Belonging to the subfamily Anatinae of the waterfowl family Anatidae, mallards live in wetlands, eat water plants and small animals, and are social animals preferring to congregate in groups or flocks of varying sizes.

Males (drakes) have green heads, while the females (hens) have mainly brown-speckled plumage. Both sexes have an area of white-bordered black or iridescent purple or blue feathers called a speculum on their wings; males especially tend to have blue speculum feathers. The mallard is 50–65 cm (20–26 in) long, of which the body makes up around two-thirds the length. The wingspan is 81–98 cm (32–39 in) and the bill is 4.4 to 6.1 cm (1.7 to 2.4 in) long. It is often slightly heavier than most other dabbling ducks, weighing 0.7–1.6 kg (1.5–3.5 lb).

The female lays 8 to 13 creamy white to greenish-buff spotless eggs, on alternate days. Incubation takes 27 to 28 days and fledging takes 50 to 60 days. The ducklings are precocial and fully capable of swimming as soon as they hatch.

The short, thick-necked Western Cattle-Egret spends most of its time in fields rather than streams. It forages at the feet of grazing cattle, head bobbing with each step, or rides on their backs to pick at ticks. This stocky white heron has yellow plumes on its head and neck during breeding season. Originally from Africa, it found its way to North America in 1953 and quickly spread across the continent. Elsewhere in the world, it forages alongside camels, ostriches, rhinos, and tortoises—as well as farmers’ tractors.

To find Western Cattle-Egrets, head to agricultural areas near wetlands. These are tropical herons, so your best chances will be in warm parts of the southern U.S. Seeing cattle-egrets is not difficult once you find the right habitat—they usually walk around in the open, on dry land, as they hunt grasshoppers and other small animals. True to their name, cattle-egrets often associate with cows and other large farm animals, waiting to strike until the cow disturbs an insect or frog. Sometimes, cattle-egrets even stand atop cows and horses, making them both easy to spot and easy to identify.The short, thick-necked Western Cattle-Egret spends most of its time in fields rather than streams.

Sometimes, cattle-egrets even stand atop cows and horses, making them both easy to spot and easy to identify.

In 2023, ornithologists split Cattle Egret into two species: Western Cattle-Egret and Eastern Cattle-Egret. Western-Cattle Egret occurs in Africa, western Asia, southern Europe, and the Americas. Eastern Cattle-Egret, meanwhile, inhabits southern and eastern Asia, Australia, and New Zealand.

Western Cattle-Egrets are native to Africa but somehow reached northeastern South America in 1877. They continued to spread, arriving in the United States in 1941 and nesting there by 1953. In the next 50 years, they became one of the most abundant of the North American herons, showing up as far north as Alaska and Newfoundland.

Western Cattle-Egrets follow large animals or machines and eat invertebrates stirred up from the ground. They will fly toward smoke from long distances away, to catch insects fleeing a fire.

The Western Cattle-Egret has a broad and flexible diet that occasionally includes other birds. In the Dry Tortugas off the coast of Florida, migrating cattle egrets have been seen hunting migrating warblers.

Western and Eastern Cattle-Egrets have many names around the world, usually referencing the grazing animals they team up with to forage. In various languages they are known as cow cranes, cow herons, cow birds, elephant birds, rhinoceros egrets, and hippopotamus egrets.

The oldest Western Cattle-Egret on record was at least 17 years old when it was captured and released in Pennsylvania in 1979. It was originally banded in Maryland in 1962.

The Black Redstart (Phoenicurus ochruros) is a small, charismatic passerine bird, exhibiting a blend of dark and vibrant plumage. Males are distinguished by their dark grey to black upperparts and breast, with a striking orange-red rump and tail. Females and juveniles are more subdued in color, with grey to grey-brown feathers and the same vivid tail coloration that is the hallmark of the species.

Adult males are easily identified by their dark upperparts and black breast, contrasting with the orange-red lower rump and tail. The belly and undertail may vary from blackish-grey to orange-red, depending on the subspecies. Females and juveniles are less conspicuous, with overall greyer tones and a distinctive orange-red rump and tail. The presence of pale fringes on the secondaries forms a whitish wing panel in some subspecies.

The Black Redstart has adapted remarkably to urban environments, often found nesting in crevices or holes within buildings. Originally a dweller of stony mountainous regions, it now thrives in industrial areas with similar structural features.

This species is widely distributed across south and central Europe, Asia, and north-west Africa. It is a resident in milder regions, while populations in the northeast migrate to warmer areas during winter.

The Black Redstart is known for its robin-like movements, including quick ducks of the head and body, and frequent tail flicking. Males possess a rattling song and a tick call, adding to their distinctive presence.

The Black Redstart's vocal repertoire includes a variety of calls, which differ among subspecies. The male's song is a rattling melody, while its call is a sharp 'tick', often heard during its active foraging.

Typically monogamous, the Black Redstart begins breeding in mid-April. Nests are built by females in sheltered nooks, lined with soft materials. Clutches consist of 4 to 6 eggs, incubated primarily by the female. Both parents tend to the fledglings, which leave the nest after 12 to 19 days.

The Common Redstart shares some similarities but can be distinguished by its different behavior, ecological requirements, and less dark plumage.

The Black Redstart's diet includes insects, which it often catches mid-flight. It is also known to forage in coastal areas for tiny crustaceans and flies.

The IUCN Red List classifies the Black Redstart as Least Concern, indicating a stable population across its extensive range.

26-12-2018 OLIVA MARJAL, VALENCIA - HOUSE SPARROW (MALE) (Passer domesticus)

The house sparrow (Passer domesticus) is a member of the sparrow family Passeridae. This small bird typically measures around 16 cm (6.3 in) in length and weighs between 24–39.5 g (0.85–1.39 oz). The species exhibits sexual dimorphism, with females and young birds displaying pale brown and grey plumage, while males are characterized by more vibrant black, white, and brown markings.

Males can be identified by their bright black, white, and brown markings, with a distinctive black bib, white cheeks, and a grey crown. Females lack the striking head patterns of males and are predominantly buffish with softer coloration. Juveniles resemble adult females but are generally paler with less defined markings.

The house sparrow is highly adaptable and can thrive in both urban and rural environments. It is commonly found in close association with human habitation and avoids dense forests, grasslands, polar regions, and deserts far from human development.

Native to Europe, the Mediterranean Basin, and much of Asia, the house sparrow has been introduced to various regions worldwide, including parts of Australasia, Africa, and the Americas, making it one of the most widely distributed wild birds.

House sparrows are social birds, often seen in flocks. They exhibit a range of behaviors, including dust or water bathing and communal roosting. Males are known to be territorial around their nesting sites.

The house sparrow's vocalizations are predominantly variations of a simple chirping call. Males may sing or give an "ecstatic call" during the breeding season, and the species uses a variety of calls for different social interactions.

House sparrows are generally monogamous and may mate for life. They can breed in the season following their hatching and often produce multiple clutches per year, with each clutch containing up to five eggs. Nest sites are varied, with a preference for cavities.

An opportunistic feeder, the house sparrow's diet consists mainly of seeds from grains and weeds, but it also consumes insects and other invertebrates, especially during the breeding season when feeding young.
