22-3-2024 BIOPARC, VALENCIA - COMMON DWARF MONGOOSE (Helogale parvula) NIKON P900

The common dwarf mongoose (Helogale parvula ) is a mongoose species native to Angola, northern Namibia, KwaZulu-Natal in South Africa, Zambia and East Africa. It is part of the genus Helogale and as such is related to H. hirtula.

Common dwarf mongooses are the smallest African carnivores. They have a large pointed head, small ears, a long tail, short limbs, and long claws. Their soft fur is very variable in color, ranging from yellowish red to very dark brown.

Common dwarf mongooses range from East to southern Central Africa, from Ethiopia to the provinces of Limpopo and Mpumalanga in the Republic of South Africa. These animals are usually found in dry grassland, open woodlands, wooded savannas, and bushland. They are especially common in areas with many termite mounds and avoid dense forests and deserts.

Common dwarf mongooses are diurnal animals. They are highly social and live in extended family groups of 2 to 30 animals. There is a strict hierarchy among same-sexed animals within a group, headed by the dominant pair (normally the oldest group members). All group members cooperate in helping to rear the pups and in guarding the group against predators. Dwarf mongooses are territorial, and each group uses an area of approximately 30-60 hectares. They sleep at night in disused termite mounds, although they occasionally use piles of stones, hollow trees, etc. Mongooses mark their territory with anal gland and cheek gland secretions and latrines. Territories often overlap slightly, which can lead to confrontations between different groups, with the larger group tending to win. Common dwarf mongooses begin and end each day sunbathing and socializing with the members of their groups. The rest of the day these animals spend looking for food among brush and rocks. They communicate with each other with the help of twitters, whistles, trills, and vibrations. 

22-3-2024 BIOPARC, VALENCIA - ADDAX (MALE) (Addax nasomaculatus) NIKON P900


The addax (Addax nasomaculatus) is an antelope native to the Sahara Desert. The only member of the genus Addax, it was first described scientifically by Henri de Blainville in 1816. Addax are well-adapted to exist in their desert habitat, as they can live without water for long periods of time. Although extremely rare in their native habitat due to unregulated hunting, addax are quite common in captivity. They were once abundant in North Africa but currently are only native to a few countries. They are extirpated from Algeria, Egypt, Libya, Sudan, and Western Sahara, but have been reintroduced into Morocco and Tunisia.

The addax is a spiral-horned antelope. The horns, which are found on both males and females, have two to three twists and are typically 55-80 cm (22-31 in) in females and 70-85 cm (28-33 in) in males, although the maximum recorded length is 109.2 cm (43.0 in). The lower and middle portions of the horns are marked with a series of 30 to 35 ring-shaped ridges. The coloring of the addax's coat varies with the season. In the winter, it is greyish-brown with white hindquarters and legs, and long, brown hair on the head, neck, and shoulders. In the summer, the coat turns almost completely white or sandy blonde. Their head is marked with brown or black patches that form an 'X' over their noses. They have scraggly beards and prominent red nostrils. Long, black hairs stick out between their curved and spiraling horns, ending in a short mane on the neck. The tail is short and slender, ending in a puff of black hair. The hooves are broad with flat soles and strong dewclaws to help them walk on soft sand. All four feet possess scent glands. The females of this species are smaller than the males.

22-3-2024 BIOPARC, VALENCIA - GRANT'S ZEBRA (Equus quagga ssp. boehmi) NIKON P900

Grant's zebra (Equus quagga boehmi ) is the smallest of the seven subspecies of the plains zebra. This subspecies represents the zebra form of the Serengeti-Mara ecosystem.

This northern subspecies is vertically striped in front, horizontally on the back legs, and diagonally on the rump and hind flanks. Shadow stripes are absent or only poorly expressed. The stripes, as well as the inner spaces, are broad and well defined. Northerly specimens may lack a mane. Grant’s zebras grow to be about 182 to 243 cm (6-8 ft) long and 120 to 140 cm (3.9 to 4.6 ft) tall, and generally weigh about 300 kg (660 lb). The zebras live in family groups of up to 18 zebras, and they are led by a single stallion. Grant’s zebras typically live 20 years.

22-3-2024 BIOPARC, VALENCIA - NORTHERN PINTAIL (Anastasia acuta) NIKON P900

The Northern pintail (Anas acuta) is a duck species that has a wide geographic distribution. Unusually for a bird with such a large range, it has no geographical subspecies if the possibly conspecific duck Eaton's pintail is considered to be a separate species. The Northern pintail is a large bird, and the male's long central tail feathers give rise to the species' English and scientific names.

Northern pintails breed across northern areas of the Palearctic south to about Poland and Mongolia, and in Canada, Alaska, and the Midwestern United States. Mainly in winters south of their breeding range, reaches almost to the equator in Panama, northern sub-Saharan Africa, and tropical South Asia. Small numbers migrate to Pacific islands, particularly Hawaii, where a few hundred birds winter on the main islands. In parts of the range, such as Great Britain and the northwestern United States, pintails may be present all year. The breeding habitat of Northern pintails is open unwooded wetlands, such as wet grassland, lakeside, or tundra. In winter, they can be found in a wider range of open habitats, such as sheltered estuaries, brackish marshes, coastal lagoons, and flooded and dry agricultural fields.

The Northern pintail broadly overlaps in size with the similarly widespread mallard, but is more slender, elongated, and gracile, with a relatively longer neck and (in males) a longer tail. The unmistakable breeding plumaged male has a chocolate-brown head and white breast with a white stripe extending up the side of the neck. Its upperparts and sides are grey, but elongated grey feathers with black central stripes are draped across the back from the shoulder area. The vent area is yellow, contrasting with the black underside of the tail, which has the central feathers elongated to as much as 10 cm (3.9 in). The bill is bluish and the legs are blue-grey. The adult female is mainly scalloped and mottled in light brown with a more uniformly grey-brown head, and its pointed tail is shorter than the male's; it is still easily identified by its shape, long neck, and long grey bill. In non-breeding (eclipse) plumage, the drake pintail looks similar to the female but retains the male upperwing pattern and long grey shoulder feathers. Juvenile birds resemble the female, but are less neatly scalloped and have a duller brown speculum with a narrower trailing edge.

18-10-2015 LAKELAND, THURROCK - CANADA GOOSE (Branta canadensis) (JUVENILE) NIKON P900

 

A big, brownish, black and white goose. Differs from Barnacle Goose by a light brownish breast and a more brownish body. Base of bill and forehead black. White tail-coverts but black tail-feathers, and uniformly dark brown wings. Generally gives a large and long-necked impression, but different subspecies shows a lot of variation.

In recent years, Canada goose populations in some areas have grown substantially, so much so that many consider them pests for their droppings, bacteria in their droppings, noise, and confrontational behavior. This problem is partially due to the removal of natural predators and an abundance of safe, human-made bodies of water near food sources, such as those found on golf courses, in public parks and beaches, on sports fields, and in planned communities. Due in part to the interbreeding of various migratory subspecies with the introduced non-migratory giant subspecies, Canada geese are frequently a year-round feature of such urban environments.

22-3-2024 BIOPARC, VALENCIA - AFRICAN SPOONBILL (Platalea alba)

The African spoonbill (Platalea alba ) is a long-legged wading bird of the ibis and spoonbill family Threskiornithidae. The species is widespread across Africa and Madagascar, including Botswana, Kenya, Mozambique, Namibia, South Africa, and Zimbabwe.

The African spoonbill is a long-legged wading bird that is almost unmistakable through most of its range. During the breeding season, the bird is all white except for its red legs and face and long grey spatulate bill. Immature birds lack the red face and have a yellow bill. Unlike herons, spoonbills fly with their necks outstretched.

African spoonbills are widespread across sub-Saharan Africa and Madagascar, including Botswana, Kenya, Mozambique, Namibia, South Africa, and Zimbabwe. They live in marshy wetlands with some open shallow water; these include river banks, lake shores, marshes, flood plains, reservoirs, and sometimes coastal lagoons and estuaries.

African spoonbills are social birds that are active during the day. Outside of the breeding season, they can be found singly, in pairs, or in small groups. These birds spend most of their time walking slowly in shallow water searching for food. They fish using their open bill to catch prey items by swinging it from side-to-side in the water. The moment any small aquatic creature touches the inside of the bill it is snapped shut. Long legs and thin, pointed toes enable them to walk easily through varying depths of water. When not foraging African spoonbills rest along the shores, often in groups; they are usually silent and only when alarmed produce loud grunts.

African spoonbills are monogamous and form pairs, however, some males may attempt to mate with more than one female during the breeding season (polygynous behavior). The birds begin breeding in the winter, which lasts until spring. They nest in colonies in trees or reedbeds. Their nest is built from sticks and reeds and lined with leaves. The female lays 3 to 5 eggs, usually during the months of April or May. The eggs are incubated by both parents for up to 29 days. Upon hatching the chicks are cared for by both parents for around 20 to 30 days and are ready to leave the nest soon afterward. They begin flying after another 4 weeks.

22-3-2024 BIOPARC, VALENCIA - EUROPEAN MOORHEN (Gallinula chloropus)

The Common moorhen (Gallinula chloropus) is a bird species in the rail family (Rallidae) found across many parts of the Old World. These birds live around well-vegetated marshes, ponds, canals, and other wetlands. The word 'moor' as a part of their name is an old sense meaning marsh.

 Common moorhens have predominantly black and brown plumage, with the exception of a white under-tail, white streaks on the flanks, yellow legs, and a red frontal shield. The bill is red with a yellow tip. The young are browner and lack the red shield. The frontal shield of the adult has a rounded top and fairly parallel sides; the tailward margin of the red unfeathered area is a smooth waving line.

Сommon moorhens are widespread across Europe, Asia, and Africa. Populations in areas where the waters freeze, such as eastern Europe, will migrate to more temperate climates. In China, Common moorhens are largely resident south of the Yangtze River, whilst northern populations migrate in the winter. These birds live around well-vegetated marshes, ponds, canals, and other wetlands. They can even be found in city parks and urban areas.

2-4-2024 MONTE CORONA, VALENCIA - WAVE MOTH (idaea cervantaria)


Small moth of the Geometridae family; It is distributed in southeastern France, the Iberian Peninsula and northwest Africa; present in the warm areas of the Iberian Peninsula.

Geometric shape, with the front wings ending in a sharp edge and the rear wings with a wide and rounded shape; gray background color, this gray can be darker, lighter or with an ocher tone; Two irregular lines are drawn on the wings, one proximal and one distal on the wing dorsum, a dark dot on each wing, a subterminal dark line formed by small black strokes, unlike other Idaea, which only have a subterminal dotted line; long ocher fimbriae.

It lives in dry and sunny places, rocky slopes.

I do not know the food plants for the larvae, but this photograph corresponds to an open area of ​​dryland crops, where trees and shrubs are scarce and grasses and other wild herbaceous plants are abundant.

They fly in one generation a year, the months of May to July

22-3-2024 BIOPARC, VALENCIA - AFRICAN SPURRED TORTOISE (Centrochelys sulcata)

The African spurred tortoise (Centrochelys sulcata), also called the sulcata tortoise, is an endangered species of tortoise inhabiting the southern edge of the Sahara Desert, the Sahel, in Africa. It is the largest mainland species of tortoise in Africa, and the third-largest in the world, after the Galapagos tortoise and Aldabra giant tortoise. It is the only living species in its genus, Centrochelys, with the five other species in the family already extinct.

In 1779 the English illustrator John Frederick Miller included a hand-coloured plate of the African spurred tortoise in his Icones animalium et plantarum and coined the binomial name Testudo sulcata.[4] Its specific name sulcata is from the Latin word sulcus meaning "furrow" and refers to the furrows on the tortoise's scales.[5] The species was subsequently given other binomial names. There are no recognized subspecies despite there being two separate populations, one in Western Africa and the other in Eastern Africa. There are also three different, yet similar, haplotypes. One haplotype is found in and closely around Sudan, another is found in the western portion of their range, and the last haplotype is found in Senegal, Mali, and Sudan.

22-3-2024 BIOPARC, VALENCIA - SAVANNAH ELEPHANT (Loxodonta Africana)

The African bush elephant (Loxodonta africana), also known as the African savanna elephant, is one of two extant African elephant species and one of three extant elephant species. It is the largest living terrestrial animal, with bulls reaching an average shoulder height of 3.04–3.36 metres (10.0–11.0 ft) and a body mass of 5.2–6.9 t (5.7–7.6 short tons) (with the largest recorded specimen having a shoulder height of 3.96 m (13 ft 0 in) and a body mass of 10.4 t (11.5 short tons)).

It is distributed across 37 African countries and inhabits forests, grasslands and woodlands, wetlands and agricultural land. Since 2021, it has been listed as Endangered on the IUCN Red List. It is threatened foremost by habitat destruction, and in parts of its range also by poaching for meat and ivory.

It is a social mammal, travelling in herds composed of cows and their offspring. Adult bulls usually live alone or in small bachelor groups. It is a herbivore, feeding on grasses, creepers, herbs, leaves, and bark. The menstrual cycle lasts three to four months, and females are pregnant for 22 months, the longest gestation period of any mammal.


The African bush elephant occurs in sub-Saharan Africa which includes Uganda, Kenya, Tanzania, Botswana, Zimbabwe, Namibia, Zambia, and Angola. It moves between a variety of habitats, including subtropical and temperate forests, dry and seasonally flooded grasslands, woodlands, wetlands, and agricultural land from sea level to mountain slopes. In Mali and Namibia, it also inhabits desert and semi-desert areas.

In Ethiopia, the African bush elephant has historically been recorded up to an elevation of 2,500 m (8,200 ft). By the late 1970s, the population had declined to a herd in the Dawa River valley and one close to the Kenyan border.

22-3-2024 BIOPARC, VALENCIA - FERRUGINOUS DUCK (MALE) (Aythya nyroca)


The ferruginous duck (Aythya nyroca), also known as ferruginous pochard, common white-eye or white-eyed pochard, is a medium-sized diving duck from Eurosiberia. The scientific name is derived from Greek aithuia an unidentified seabird mentioned by authors including Hesychius and Aristotle, and nyrok, the Russian name for a duck.

The breeding male is a rich, dark chestnut on the head, breast and flanks with contrasting pure white undertail coverts. In flight the white belly and underwing patch are visible. The females are duller and browner than the males. The male has a yellow eye and the females have a dark eye.

The ferruginous duck prefers quite shallow fresh waterbodies with rich submerged and floating vegetation with dense stands of emergent vegetation on the margins. In some areas it will use saline or brackish pools or wetlands. On passage and wintering will also frequent coastal waters, inland seas and large, open lagoons.

The breeding range of the ferruginous duck is from Iberia and the Maghreb east to western Mongolia, south to Arabia, although in the west is now scarce and localised and locally extirpated in some countries. The duck winters throughout the Mediterranean Basin and the Black Sea, smaller number migrate into sub-Saharan Africa via the Nile Valley. Eastern birds winter in south and south-east Asia.

22-3-2024 BIOPARC, VALENCIA - CHIMPANZEE (Pan troglodytes)


The chimpanzee (/tʃɪmpænˈzi/; Pan troglodytes), or simply known as the chimp, is a species of great ape native to the forests and savannahs of tropical Africa. It has four confirmed subspecies and a fifth proposed one. When its close relative the bonobo was more commonly known as the pygmy chimpanzee, this species was often called the common chimpanzee or the robust chimpanzee. The chimpanzee and the bonobo are the only species in the genus Pan. Evidence from fossils and DNA sequencing shows that Pan is a sister taxon to the human lineage and is thus humans' closest living relative. The chimpanzee is covered in coarse black hair, but has a bare face, fingers, toes, palms of the hands, and soles of the feet. It is larger and more robust than the bonobo, weighing 40–70 kg (88–154 lb) for males and 27–50 kg (60–110 lb) for females and standing 150 cm (4 ft 11 in).

The chimpanzee lives in groups that range in size from 15 to 150 members, although individuals travel and forage in much smaller groups during the day. The species lives in a strict male-dominated hierarchy, where disputes are generally settled without the need for violence. Nearly all chimpanzee populations have been recorded using tools, modifying sticks, rocks, grass and leaves and using them for hunting and acquiring honey, termites, ants, nuts and water. The species has also been found creating sharpened sticks to spear small mammals. Its gestation period is eight months. The infant is weaned at about three years old but usually maintains a close relationship with its mother for several years more.

The chimpanzee is listed on the IUCN Red List as an endangered species. Between 170,000 and 300,000 individuals are estimated across its range. The biggest threats to the chimpanzee are habitat loss, poaching, and disease. Chimpanzees appear in Western popular culture as stereotyped clown-figures and have featured in entertainments such as chimpanzees' tea parties, circus acts and stage shows. Although many chimpanzees have been kept as pets, their strength, aggressiveness, and unpredictability makes them dangerous in this role. Some hundreds have been kept in laboratories for research, especially in the United States. Many attempts have been made to teach languages such as American Sign Language to chimpanzees, with limited success.

22-3-2024 BIOPARC, VALENCIA - RED RIVER HOG (Potamochoerus porcus)

The red river hog (Potamochoerus porcus) or bushpig (a name also used for Potamochoerus larvatus) is a wild member of the pig family living in Africa, with most of its distribution in the Guinean and Congolian forests. It is rarely seen away from rainforests, and generally prefers areas near rivers or swamps.

The red river hog lives in rainforests, wet dense savannas, and forested valleys, and near rivers, lakes and marshes. The species' distribution ranges from the Congo area and Gambia to the eastern Congo, southwards to the Kasai and the Congo River. The exact delineation of its range versus that of the bushpig is unclear; but in broad terms, the red river hog occupies western and central Africa, and the bushpig occupies eastern and southern Africa. Where the two meet, they are sometimes said to interbreed, although other authorities dispute this. Although numerous subspecies have been identified in the past, none are currently recognised.

22-3-2024 BIOPARC, VALENCIA - FOREST BUFFALO (FEMALE) (Syncerus caffer ssp. nanus)

The African forest buffalo (Syncerus caffer nanus), also known as the dwarf buffalo or the Congo buffalo, is the smallest subspecies of the African buffalo. It is related to the Cape buffalo (Syncerus caffer caffer), the Sudan buffalo (Syncerus caffer brachyceros), and the Nile buffalo (Syncerus caffer aequinoctialis). However, it is the only subspecies that occurs mainly in the rainforests of Central Africa and Western Africa, with an annual rainfall around 1,500 mm (59 in). It has been proposed to represent a distinct species, Syncerus nanus.

The African forest buffalo is a small subspecies of the African buffalo. Cape buffaloes weigh 425 to 870 kg (937 to 1,918 lb), whereas African forest buffaloes are much lighter, weighing in at 250 to 320 kg (550–705 lbs). Weight is not the only differentiation, however; this subspecies has a reddish-brown hide that is darker in the facial area. The shape and size of the horns distinguish African forest buffalo from the other subspecies. African forest buffalo have much smaller horns than their savanna counterparts the Cape, Sudan and Nile buffalo. Cape buffalo horns often grow and fuse together, but African forest buffalo horns rarely fuse. 

22-3-2024 BIOPARC, VALENCIA - FOREST SITATUNGA (Tragelaphus spekii ssp. gratus)


 Larger in body than the Zambezi Sitatunga found in Zambia and Botswana, the forest Sitatunga has a darker coat with distinct white stripes and a white dorsal ridge.

The species is still present in several countries in Central Africa ; it is discontinuously distributed in West Africa

The sitatunga is semi aquatic, and so specialized that it occurs only in swamps or permanent marshes. Partial to papyrus and phragmites within swamps, it may also occur in wetlands dominated by bullrushes, reeds, and sedges. They frequent the deepest parts of the swamp. (Estes, 1991; Nowak, 1991)


The Sitatunga, a swamp-dwelling antelope, exhibits great elongation of the hooves, which have a wide splay and naked padlike pattern. They possess unique flexibility of the joints at the feet, representing structural adaptations for walking on boggy and marshy ground.

Coloration varies geographically and individually. Males are gray-brown to chocolate-brown, females are brown to bright chestnut, and calves are bright rufous-red, woolly coated, spotted, and striped. Adults are long coated and have characteristic whiteish marks on the face, ears, cheeks, body, legs, and feet.

Males are considerably larger than females (100 cm tall vs. 75-90 cm tall). Males possess horns ranging in length from 508-924 mm. Horns are characterized by two twists and are ivory tipped.

22-3-2024 BIOPARK, VALENCIA - RING TAILED LEMUR (Lemur catta)

The Ring-tailed lemur has a slender frame and narrow face, fox-like muzzle. Its long, bushy tail is ringed in alternating black and white transverse bands, numbering 12 or 13 white rings and 13 or 14 black rings, and always ending in a black tip. The total number of rings nearly matches the approximate number of caudal vertebrae (~25). Its tail is longer than its body and is not prehensile. Instead, it is only used for balance, communication, and group cohesion. The pelage (fur) is so dense that it can clog electric clippers. The ventral (chest) coat and throat are white or cream. The dorsal (back) coat varies from gray to rosy-brown, sometimes with a brown pygal patch around the tail region, where the fur grades to pale gray or grayish brown. The dorsal coloration is slightly darker around the neck and crown. The hair on the throat, cheeks, and ears is white or off-white and also less dense, allowing the dark skin underneath to show through. The muzzle is dark grayish and the nose is black, and the eyes are encompassed by black triangular patches. Facial vibrissae (whiskers) are developed and found above the lips (mystacal), on the cheeks (genal), and on the eyebrow (superciliary). Vibrissae are also found slightly above the wrist on the underside of the forearm. The ears are relatively large compared to other lemurs and are covered in hair, which has only small tufts if any. Although slight pattern variations in the facial region may be seen between individuals, there are no obvious differences between the sexes.


 The natural range of this species occupies the south and southwest Madagascar, where scattered populations of Ring-tailed lemurs are found from Tolagnaro in the southeast to Morondava on the west coast and Ambalavao inland. Additionally, a single, isolated population inhabits the Andringitra Massif on the southeastern plateau of the island. Preferred types of habitat are spiny forests, lowland gallery forests, dry scrubs, dry deciduous forests, and, sometimes, rock canyons. Meanwhile, the population in the above-mentioned Andringitra Massif lives at higher elevations, among bare rocks, low bushes, and subalpine vegetation. This area is known to have one of the harshest climates on the island.

22-3-2024 BIOPARK, VALENCIA - AFRICAN SACRED IBIS (Threskiornis aethiopicus ssp. aethiopicus)


The African sacred ibis (Threskiornis aethiopicus ) is a wading bird native to Africa and the Middle East. It is especially known for its role in the religion of the Ancient Egyptians, where it was linked to the god Thoth; despite this, the species is currently extirpated from Egypt.

African sacred ibises have all-white body plumage apart from dark plumes on the rump. Males are generally slightly larger than females.

The bald head and neck, thick curved bill, and legs of these birds are black. The white wings show a black rear border in flight. The eyes are brown with a dark red orbital ring. Sexes are similar, but juveniles have dirty white plumage, a smaller bill and some feathering on the neck, greenish-brown scapular, and more black on the primary coverts.

22-3-2024 BIOPARK, VALENCIA - RED CRESTED POCHARD (MALE) (Netta rufina)

The red-crested pochard (Netta rufina ) is a large diving duck. The scientific name is derived from Greek Netta "duck", and Latin rufina, "golden-red" (from rufus, "ruddy"). Its breeding habitat is lowland marshes and lakes in southern Europe and it extends from the steppe and semi-desert areas on the Black Sea to Central Asia and Mongolia, wintering in the Indian Subcontinent and Africa. It is somewhat migratory, and northern birds winter further south into north Africa.

The adult male is unmistakable. It has a rounded orange head, red bill and black breast. The flanks are white, the back brown, and the tail black. The female is mainly a pale brown, with a darker back and crown and a whitish face. Eclipse males are like females but with red bills. They are gregarious birds, forming large flocks in winter, often mixed with other diving ducks, such as common pochards. They feed mainly by diving or dabbling. They eat aquatic plants, and typically upend for food more than most diving ducks.

A wheezing veht call can be given by the male. Series of hoarse vrah-vrah-vrah calls can also be heard from females.

Red-crested pochards build nests by the lakeside among vegetation and lay 8–12 pale green eggs. The birds' status in the British Isles is much confused because there have been many escapes and deliberate releases over the years, as well as natural visitors from the continent. However, it is most likely that they are escapees that are now breeding wild and have built up a successful feral population. They are most numerous around areas of England including Gloucestershire, Oxfordshire, Northamptonshire and also spotted in Leicestershire.

The red-crested pochard is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.

Larger than a Pochard, the male has an orange-brown head with a red beak and pale flanks (lower sides). Females are brown with pale cheeks. In flight, they show whitish underwings. They dive, dabble and up-end for their food. There is a large population in Spain but smaller numbers in France, Netherlands and Germany. Occasional wild birds may come to the UK from the Continent. The UK breeding birds almost certainly all come from escaped birds.

The red-crested pochard is naturally found in a wide range extending from southern and central Europe across central Asia, as far west as Mongolia. Its attractive appearance has made it a popular bird in wildfowl collections in the UK. Over the years, red-crested pochards have escaped from collections and nested in the wild, leading to an established population in England.

It's possible that some of the red-crested pochards seen in the UK, particularly in southeast England, have arrived on their own from continental Europe. Over the last century, the European population has spread north into the Netherlands and Germany. They are migratory, flying between breeding grounds and wintering sites.

Red-crested pochards are usually found on freshwater lakes and pools, particularly with reedbeds. They often feed at the surface, but can also dive for food. In winter they gather in large flocks.


Red-crested pochards prefer to nest in eutrophic ponds and lakes that are bordered by emergent halophytes and beds of macrophytes. They also nest near slow-current rivers with clearings of open water or islands with shrubs and grasses. Prior to the 1980's, red-crested pochards preferred nesting near brackish water. Since then, nearly the entire breeding population has changed its habitat to freshwater marshes and reed beds, likely as a response to growing populations of yellow-legged gulls and the predators they attract. 

During their molting period, red-crested pochards no longer fly. They seek out areas of open water (coastal, inland, brackish, or fresh) with an abundance of charophyte beds. In the winter months, lakes and ponds are used as daytime resting areas and the existing vegetation provides some shelter. Preferred habitats are in open spaces that are free from disturbances and contain accessible feeding sites.

30-3-2024 RIO SERPIS GANDIA, VALENCIA - EURASIAN BLACKCAP (FEMALE) (Sylvia atricapilla)

The Eurasian blackcap (Sylvia atricapilla) is a common and widespread warbler that breeds in much of Europe, western Asia, and northwestern Africa. Its rich and varied song has led to the blackcap being described as the "mock nightingale" and it has been featured in literature, films, and music.

The Eurasian blackcap is mainly grey in color with distinct male and female plumages. The adult male has olive-grey upperparts, other than a paler grey nape and a neat black cap on the head. The underparts are light grey, becoming silvery white on the chin, throat, and upper breast. The tail is dark grey, with an olive tint to the outer edge of each feather. The bill and long legs are grey, and the iris is reddish brown. The female resembles the male but has a reddish-brown cap and a slightly browner tone to the grey of the upperparts. Juveniles are similar to the female, but their upperparts have a slight rufous tinge, and the breast and flanks have a more olive tone; young males have darker brown cap than their female counterparts.


 

30-3-2024 RIO SERPIS GANDIA, VALENCIA - SPOTLESS STARLING (Sturnus unicolor)


The spotless starling (Sturnus unicolor ) is a passerine bird in the starling family, Sturnidae. It is closely related to the common starling (S. vulgaris ), but has a much more restricted range, confined to the Iberian Peninsula, Northwest Africa, southernmost France, and the islands of Sicily, Corsica and Sardinia. It is largely non-migratory.

The spotless starling (Sturnus unicolor ) is a passerine bird in the starling family, Sturnidae. It is closely related to the common starling (S. vulgaris ), but has a much more restricted range, confined to the Iberian Peninsula, Northwest Africa, southernmost France, and the islands of Sicily, Corsica and Sardinia. It is largely non-migratory.

The adult spotless starling is very similar to the common starling, but marginally larger (21–23 cm length; 70–100 g weight), and has darker, oily-looking black plumage, slightly purple- or green-glossed in bright light, which is entirely spotless in spring and summer, and only with very small pale spots in winter plumage, formed by the pale tips of the feathers. It also differs in having conspicuously longer throat feathers (twice the length of those on common starlings), forming a shaggy "beard" which is particularly obvious when the bird is singing. Its legs are bright pink. In summer, the bill is yellow with a bluish base in males and a pinkish base in females; in winter, it is duller, often blackish. Young birds are dull brown, darker than young common starlings, and have a black bill and brown legs. Confusion with the common starling is particularly easy during the winter, when common starlings are abundant throughout the spotless starling's range, but also in summer where their breeding ranges overlap in northeastern Spain and the far south of France. It can also be confused with the common blackbird (Turdus merula ), which differs most obviously in its longer tail and lack of plumage gloss.

Like the common starling, it walks rather than hops, and has a strong direct flight, looking triangular-winged and short-tailed. It is a noisy bird and a good mimic; its calls are similar to the common starling's, but louder.

30-3-2024 RIO SERPIS GANDIA, VALENCIA - EUROPEAN SERIN (MALE) (Serinus serinus)


The European serin is a small short-tailed bird, 11–12 cm in length. The upper parts are dark-streaked greyish green, with a yellow rump. The yellow breast and white belly are also heavily streaked. The male has a brighter yellow face and breast, yellow wing bars and yellow tail sides. The song of this bird is a buzzing trill, very familiar in Mediterranean countries.

It breeds across southern and central Europe and North Africa. Southern and Atlantic coast populations are largely resident, but the northern breeders migrate further south in Europe for the winter. Open woodland and cultivation, often with some conifers, is favoured for breeding. It builds its nest in a shrub or tree, laying 3–5 eggs. It forms flocks outside the breeding season, sometimes mixed with other finches.

The food is mainly seeds, and, in the breeding season, insects. This small serin is an active and often conspicuous bird.

30-3-2024 RIO SERPIS GANDIA, VALENCIA - EURASIAN COLLARED DOVE (Streptopelia decaocto)


The Eurasian collared dove (Streptopelia decaocto) is a dove species native to Europe and Asia. During the 20th century, the Eurasian collared dove spectacularly expanded its range from the Middle East to right across Europe. Accidentally introduced in 1974 into the Bahamas, this pale chunky bird soon spread to the mainland in Florida. A relative of the mourning dove, its name comes from its black half-collar around its neck.

The Eurasian collared dove is grey-buff to pinkish-grey overall, a little darker above than below, with a blue-grey underwing patch. The tail feathers are grey-buff above, and dark grey and tipped white below; the outer tail feathers are also tipped whitish above. It has a black half-collar edged with white on its nape. The short legs are red and the bill is black. The iris is red, but from a distance, the eyes appear to be black, as the pupil is relatively large and only a narrow rim of reddish-brown iris can be seen around the black pupil. The eye is surrounded by a small area of bare skin, which is either white or yellow. The two sexes are virtually indistinguishable; juveniles differ in having a poorly developed collar, and a brown iris.

30-3-2024 RIO SERPIS GANDIA, VALENCIA - SMALL WHITE BUTTERFLY (Pieris rapae)


Pieris rapae is a small- to medium-sized butterfly species of the whites-and-yellows family Pieridae. It is known in Europe as the small white, in North America as the cabbage white or cabbage butterfly, on several continents as the small cabbage white, and in New Zealand as the white butterfly. The butterfly is recognizable by its white color with small black dots on its wings, and it can be distinguished from P. brassicae by its larger size and the black band at the tip of its forewings.

The caterpillar of this species, often referred to as the "imported cabbageworm", is a pest to crucifer crops such as cabbage, kale, bok choy and broccoli. Pieris rapae is widespread in Europe and Asia; it is believed to have originated in the Eastern Mediterranean region of Europe, and to have spread across Eurasia thanks to the diversification of brassicaceous crops and the development of human trade routes. Over the past two centuries, it spread to North Africa, North America, New Zealand, and Australia, as a result of accidental introductions.

30-3-2024 RIO SERPIS GANDIA, VALENCIA - WESTERN CATTLE EGRET (Bubulcus ibis ssp. ibis)

 


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

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

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

28-3-2024 VILLALONGA RESERVOIR, VALENCIA - EURASIAN GREAT CORMORANT (Phalacrocorax carbo)

Great cormorants are monogamous, with pairs sometimes reuniting in subsequent years. The male chooses the nest site, displaying to attract the female by waving his wings up and down and flashing his white rump patch. He will also swing his head from side to side while holding his tail erect and calling loudly. The female responds by swinging her head slightly and “purring”. This species breeds at any time, depending on food resources. Breeding takes place in colonies of as many as 2,000 pairs, although colonies of a smaller size are typical. Colonies are often located close to other species, like darters, herons, and spoonbills. The parents build their nest with reeds, sticks, and seaweeds on a cliff, in a tree, or in a bush, according to the region. Often a nest is reused. 2 to 6 eggs are laid, with an average of 3-4. The parents share the incubation for 27 to 31 days. The altricial chicks hatch at intervals and fledge at about 50 days old. They remain with their parents for 50 or more days, relying on them for food. The young start to breed between 2 and 4 years old, typically when 3 years old.


Great cormorants have large populations and are widespread, although surveys are not complete across their range. Being an important fish competitor, in the past, they were almost extinct in Europe. However, in recent years increases have been observed, thanks to intensive protection. But in some countries, expanding conflicts with fish farms and fisheries lead to new persecution. Another threat is that hatchlings may be eaten by raptors before fledging.

Population number

The IUCN Red List reports that the global population of Great cormorants is about 1,400,000-2,100,000 individuals. The European population is estimated at 401,000-512,000 pairs, which equates to 803,000-1,020,000 mature individuals. Overall, currently, Great cormorants are classified as Least Concern (LC) on the IUCN Red List and their numbers today are increasing.

28-3-2024 POTRIES RESERVOIR, 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. Males are typically larger and heavier than females. 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, the Great cormorant 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 the 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 active during the day and are social birds, usually leaving roosts to forage early in the morning and returning within an hour. Little time each day is spent foraging, although parents with young tend to forage for longer. Much of the day is spent resting and preening near foraging areas or at roosts. Great cormorants generally are not aggressive towards one another, apart from at nest sites, where they exhibit territorial behavior. There may be dominance hierarchies. Outside of the breeding season, they usually gather in mixed-age, mixed-sex groups.

22-3-2024 BIOPARK, VALENCIA - 22-3-2024 BIOPARK, VALENCIA - DRILL

The drill (Mandrillus leucophaeus) is one of Africa’s most endangered mammals. It is related to baboons and even more closely to mandrills.

The drill is a large baboon with a short tail and a dark grey-brown body. This animal is among the most endangered primates in Africa. Drills exhibit well-defined sexual dimorphism with males, being up to twice as large as females. These forest baboons have pink, mauve, and blue rumps. Adult males are distinguished by pink lower lip as well as a dark grey to black face with a white chin and raised grooves on the nose. Meanwhile, females are identified by lacking the pink chin.

The natural range of this species is restricted to Cameroon, where these animals occur north of the Sanaga river and on the south-western edge of the coastal island of Fernando Poo (Bioko). The Korup National Park in the north of Cameroon holds the largest protected population of drills. The preferred habitat of these primates is mature lowland, coastal and riverine forest. However, they are also known to frequent young secondary forests of their range. They generally look for sheltered areas and avoid open terrains. 

22-3-2024 BIOPARK, VALENCIA - SRI LANKAN LEOPARD (Panthera pardus ssp. kotiya)

The Sri Lankan leopard (Panthera pardus kotiya) is a leopard subspecies native to Sri Lanka. It was first described in 1956 by Sri Lankan zoologist Paules Edward Pieris Deraniyagala.

Since 2020, the Sri Lankan leopard has been listed as Vulnerable on the IUCN Red List, as the population is estimated at less than 800 mature individuals, and is probably declining.The Sri Lankan leopard has a tawny or rusty yellow coat with dark spots and close-set rosettes. Seven females measured in the early 20th century averaged a weight of 64 lb (29 kg) and had a mean head-to-body-length of 1.04 m (3 ft 5 in) with a 77.5 cm (2 ft 6.5 in) long tail, the largest being 1.14 m (3 ft 9 in) with a 84 cm (2 ft 9 in) long tail; 11 males averaged 56 kg (124 lb), the largest being 77 kg (170 lb), and measured 1.27 m (4 ft 2 in) with a 86 cm (2 ft 10 in) long tail, the largest being 1.42 m (4 ft 8 in) with a 97 cm (3 ft 2 in) long tail.[3] The Sri Lankan leopard has possibly evolved to become a rather large leopard subspecies, because it is the apex predator in the country. Large males have been suggested to reach almost 100 kg (220 lb), but evidence for this is lacking.

Melanistic leopards are rare. Few records exist, including from Mawuldeniya, Pitadeniya, and Nallathanniya. In October 2019, the Department of Wildlife Conservation recorded live footage of a melanistic individual for the first time, a male.

The Sri Lankan leopard is still found in all habitats throughout the island in both protected and unprotected areas.

In Yala National Park, the Sri Lankan leopard as in other locations, is a solitary hunter, with the exception of females with young. Male's ranges typically overlap the smaller ranges of several females, as well as portions of the ranges of neighboring males, although exclusive core areas are apparent. They are more active and prefer hunting at night, but are also somewhat active during dawn, dusk, and daytime hours. They do not usually store their kills in trees, perhaps because similarly-sized or larger carnivores are absent in Sri Lanka. In 2001 to 2002, adult resident leopard density was estimated at 12.1 mature individuals and 21.7 individuals of all ages per 100 km2 (39 sq mi) in Block I of Yala National Park.

The Sri Lankan leopard hunts by silently stalking its prey, until it is within striking distance, when it unleashes a burst of speed to quickly pursue and pounce on its victim. The prey is usually dispatched with a single bite to the throat. Like most cats, it is pragmatic in its choice of diet, which can include small mammals, birds, and reptiles, as well as larger animals.[1] Sri Lankan axis deer make up the majority of its diet in the dry zone. The animal also preys on sambar, barking deer, wild boar, and monkeys.

No birth season or peak is apparent, with births occur across the year. Its lifespan ranges from 12 to 15 years in the wild, and up to 22 years in captivity.

The leopard is sympatric with the Sri Lankan sloth bear.

22-3-2024 BIOPARK, VALENCIA - GARGENEY (MALE) (Spatula querquedula)

The garganey (Spatula querquedula) is a small dabbling duck. It breeds in much of Europe and across the Palearctic, but is strictly migratory, with the entire population moving to southern Africa, India (in particular Santragachi), Bangladesh (in the natural reservoirs of Sylhet district) and Australasia during the winter of the Northern hemisphere, where large flocks can occur. This species was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae. Like other small ducks such as the Eurasian teal, this species rises easily from the water with a fast twisting wader-like flight.

Their breeding habitat is grassland adjacent to shallow marshes and steppe lakes.

The adult male is unmistakable, with its brown head and breast with a broad white crescent over the eye. The rest of the plumage is grey, with loose grey scapular feathers It has a grey bill and legs. In flight, it shows a pale blue speculum with a white border. When swimming it will show prominent white edges on its tertials. His crown (anatomy) is dark and his face is reddish brown.


Some care is needed in separating the brown female from the similar common teal, but the stronger face markings and more frequent head-shaking when dabbling are good indicators. Confusion with the female of the blue-winged teal is also possible, but the head and bill shape is different, and the latter species has yellow legs. Pale eyebrow, dark eye line, pale lore spot bordered by a second dark line.

Measurements:

Size: 41 cm

Wingspan: 58 - 69 cm.

Weight: 300- 440 g

These birds feed mainly by skimming rather than upending.

The male has a distinctive crackling mating call; the female is rather silent for a female duck, but can manage a feeble quack.

Garganey are rare breeding birds in the British Isles, with most breeding in quiet marshes in Norfolk and Suffolk. In Ireland a few pairs breed in County Wexford, with occasional breeding elsewhere.

The garganey is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies. The status of the garganey on the IUCN Red List is least concern.
