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.

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.

27-3-2024 CREU DE LONGA, ALBUFERA - EURASIAN KESTREL (Falco tinnunculus)


The common kestrel (Falco tinnunculus) is a bird of prey species belonging to the kestrel group of the falcon family Falconidae. It is also known as the European kestrel, Eurasian kestrel, or Old World kestrel. In the United Kingdom, where no other kestrel species commonly occurs, it is generally just called "kestrel".
This species occurs over a large range. It is widespread in Europe, Asia, and Africa, as well as occasionally reaching the east coast of North America. It has colonized a few oceanic islands, but vagrant individuals are generally rare; in the whole of Micronesia for example, the species was only recorded twice each on Guam and Saipan in the Marianas.


Common kestrels are small compared with other raptors, but larger than most songbirds. They are mainly light chestnut brown in color with blackish spots on the upperside and buff with narrow blackish streaks on the underside; the remiges are also blackish. The males have fewer black spots and streaks and their cap and tail are blue-grey. The tail is brown with black bars in females and has a black tip with a narrow white rim in both sexes. All Common kestrels have a prominent black malar stripe like their closest relatives. The cere, feet, and a narrow ring around the eye are bright yellow; the toenails, bill, and iris are dark. Juveniles look like adult females, but the underside streaks are wider; the yellow of their bare parts is paler.


Common kestrels are found in Europe, Asia, and Africa. These birds are sedentary but in the cold parts of their range, they migrate south in winter. Common kestrels live in open habitats such as tundra, taiga, grassland, shrubland, marshland, fields, and heaths. They can also be found in forested areas and readily adapt to human settlement, as long as sufficient swathes of vegetation are available. They also occur in wetlands, moorlands, arid savanna, and from the sea to the lower mountain range.


Common kestrels are usually seen alone but sometimes may travel in small flocks and nest in loose colonies. These birds hunt by day hovering about 10-20 m (35-65 ft) above the ground, searching for prey, either by flying into the wind or by soaring using ridge lift. Like most birds of prey, Common kestrels have keen eyesight enabling them to spot small prey from a distance. Once prey is sighted, the bird makes a short, steep dive toward the target. They often hunt along the sides of roads and motorways. Another favorite (but less conspicuous) hunting technique is to perch a bit above the ground cover, surveying the area. When the bird spots prey animals moving by, it will pounce on them. They also prowl a patch of hunting ground in a ground-hugging flight, ambushing prey as they happen across it. Common kestrels communicate with each other using various calls. When alarmed they utter 'kii-kii-kiikii' and in flight, the birds produce a 'kik-kik' call.


Common kestrels are monogamous and form long-lasting pair bonds. They start breeding in April or May in temperate Eurasia and between August and December in the tropics and southern Africa. Common kestrels nest in cavities, preferring holes in cliffs, trees, or buildings; in built-up areas, the birds will often nest on buildings and will reuse the old nests of other birds. Common kestrels are usually solitary nesters but may sometimes nest in loose colonies. The female lays a clutch of 3 to 7 eggs. Incubation lasts around 4 weeks, and only the female incubates the eggs. The male is responsible for providing her with food, and for some time after hatching this remains the same. Later, both parents share brooding and hunting duties until the young fledge, after 4-5 weeks. The family stays close together for a few weeks, during which time the young learn how to fend for themselves and hunt prey. They become reproductively mature and are ready to breed for the first time by the next breeding season.

27-3-2024 LLUXTENT, VALENCIA - GREAT TIT (Parus major)


The great tit (Parus major) is a small passerine bird in the tit family Paridae. It is a widespread and common species throughout Europe, the Middle East, Central Asia and east across the Palearctic to the Amur River, south to parts of North Africa where it is generally resident in any sort of woodland; most great tits do not migrate except in extremely harsh winters. Until 2005 this species was lumped with numerous other subspecies. DNA studies have shown these other subspecies to be distinct from the great tit and these have now been separated as two distinct species, the cinereous tit (Parus cinereus) of southern Asia, and the Japanese tit (Parus minor) of East Asia. The great tit remains the most widespread species in the genus Parus.

The great tit is a distinctive bird with a black head and neck, prominent white cheeks, olive upperparts and yellow underparts, with some variation amongst the numerous subspecies. It is predominantly insectivorous in the summer, but will consume a wider range of food items in the winter months, including small hibernating bats. Like all tits it is a cavity nester, usually nesting in a hole in a tree. The female lays around 12 eggs and incubates them alone, although both parents raise the chicks. In most years the pair will raise two broods. The nests may be raided by woodpeckers, squirrels and weasels and infested with fleas, and adults may be hunted by sparrowhawks. The great tit has adapted well to human changes in the environment and is a common and familiar bird in urban parks and gardens. The great tit is also an important study species in ornithology.

22-3-2024 BIOPARK, VALENCIA - COMMON WATERBUCK (Kobus ellipsiprymnus ssp. ellipsiprymnus) NIKON P950X

 

The waterbuck (Kobus ellipsiprymnus) is a large antelope found widely in sub-Saharan Africa. It is placed in the genus Kobus of the family Bovidae. It was first described by Irish naturalist William Ogilby in 1833. Its 13 subspecies are grouped under two varieties: the common or ellipsiprymnus waterbuck and the defassa waterbuck. The head-and-body length is typically between 177 and 235 cm (70 and 93 in) and the typical height is between 120 and 136 cm (47 and 54 in). In this sexually dimorphic antelope, males are taller and heavier than females. Males reach roughly 127 cm (50 in) at the shoulder, while females reach 119 cm (47 in). Males typically weigh 198–262 kg (437–578 lb) and females 161–214 kg (355–472 lb). Their coat colour varies from brown to grey. The long, spiral horns, present only on males, curve backward, then forward, and are 55–99 cm (22–39 in) long.

Waterbucks are rather sedentary in nature. As gregarious animals, they may form herds consisting of six to 30 individuals. These groups are either nursery herds with females and their offspring or bachelor herds. Males start showing territorial behaviour from the age of 5 years, but are most dominant from the six to nine. The waterbuck cannot tolerate dehydration in hot weather, and thus inhabits areas close to sources of water. Predominantly a grazer, the waterbuck is mostly found on grassland. In equatorial regions, breeding takes place throughout the year, but births are at their peak in the rainy season. The gestational period lasts 7–8 months, followed by the birth of a single calf.


Waterbucks inhabit scrub and savanna areas along rivers, lakes, and valleys. Due to their requirement for grasslands and water, waterbucks have a sparse ecotone distribution. The IUCN lists the waterbuck as being of least concern. More specifically, the common waterbuck is listed as of least concern. while the defassa waterbuck is near threatened. The population trend for both is downwards, especially that of the defassa, with large populations being eliminated from certain habitats because of poaching and human disturbance.

22-3-2024 BIOPARC, VALENCIA - AFRICAN WATTLED LAPWING (Vanellus senegallus) NIKON P900


The African wattled lapwing (Vanellus senegallus), also known as the Senegal wattled plover or simply wattled lapwing, is a large lapwing, a group of largish waders in the family Charadriidae. It is a resident breeder in most of sub-Saharan Africa outside the rainforests, although it has seasonal movements.

These are conspicuous and unmistakable birds. They are large brown waders with a black crown, white forehead and large yellow facial wattles. The tail is white, tipped black, and the long legs are yellow.

In flight, the upperwings have black flight feathers and brown coverts separated by a white bar. The underwings are white with black flight feathers. The African wattled lapwing has a loud peep-peep call.

This species is a common breeder in wet lowland habitats, especially damp grassland. It often feeds in drier habitats, such as golf courses, picking insects and other invertebrates from the ground. It lays three or four eggs on a ground scrape.

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

22-3-2024 BIOPARC, VALENCIA - ROTHSCHILD'S GIRAFFE (Giraffa camelopardalis rothschildi)

The Rothschild’s giraffe, also known as the Baringo or Ugandan giraffe is a subspecies of the Northern giraffe. It was named after the London zoologist Lionel Water Rothschild who first described the subspecies in the early 1900s.

The giraffe is the world’s tallest land mammal and the Rothschild’s giraffe is one of the tallest subspecies, growing up to 6m tall. Its colouring is unique compared to other giraffes as their markings stop half way down their legs.

Giraffes live in small herds with males and females living separately outside of the breeding season. Females give birth to a single calf after a gestation period of around 15 months.

Lifespan is 20 years.

25-3-2024 MONTE CORONA, VALENCIA - WAVE MOTH (Scopula minorata)

Scopula minorata is a moth of the family Geometridae. It was described by Jean Baptiste Boisduval in 1833. It is found in Africa south of the Sahara, the Arabian Peninsula and on the islands of the Indian Ocean. Furthermore, it is found in southern Europe. It can be distinguished from Scopula lactaria only by examination of its genitalia.

The wingspan is 15–20 millimetres (0.59–0.79 in).

25-3-2024 RIO SERPIS GANDIA, VALENCIA - EURASIAN BLACKBIRD (MALE) (Turdus merula)

The Common blackbird (Turdus merula) is a species of true thrush. It is also called the Eurasian blackbird (especially in North America, to distinguish it from the unrelated New World blackbirds), or simply the blackbird where this does not lead to confusion with a similar-looking local species. This common and conspicuous species has given rise to a number of literary and cultural references, frequently related to its song.

Common blackbirds are omnivores. They mainly eat cultivated fruits like apples, pears, strawberries, cherries, and grapes. They also eat wild berries and fruits, insects, spiders, earthworms, and some seeds, when hunting on the ground.

Common blackbirds breed in Europe, North Africa, India, and southern China. Populations in the north and east migrate to winter in Egypt and the west and southeast of Asia. Depending on latitude, Common blackbirds may be resident, partially migratory, or fully migratory. These birds live in very varied habitats, including mountainous regions and big city centers, where they inhabit open forests and forest edges, woodlands, cultivated areas, gardens, and parks if the cover is dense enough for hiding.

Common blackbirds are diurnal and eat mainly on the ground, turning the leaf litter to find the invertebrates hidden below. The bird runs for a short distance and stops suddenly to turn its head sideways to detect its prey and hops while it digs the ground with its bill to attract worms. It will feed in trees and bushes on the fruits and berries that it prefers. These birds will often take sunbaths, while flattened on grass or warm ground, with their beak open and their head inclined, and wings and tails spread. Common blackbirds are territorial, strongly defending their territory, mostly in urban areas where each pair does not have much space. Females may also fight, in defense of a good nest site. While winter food is available, Common blackbirds will stay within their territory for the year, although they will occupy different areas. Migrating birds are more gregarious, flying in small flocks and eating in loose groups at the wintering grounds.

Common blackbirds are monogamous and pairs usually stay together for life. Courtship displays begin very soon, often in February. Males sing at dawn. An individual will fan its tail and raise it vertically while drawing its head into its shoulders until it looks like a black ball with a yellow beak. The female fluffs up the feathers of her neck and rump in answer to the male’s display. Common blackbirds breed in spring and are able to produce three clutches. Females build a robust nest within vegetation, low down but well hidden, located in the fork of tree branches. Usually, 3 to 4 eggs are laid, greenish and mottled with brown. The female incubates the eggs, sometimes relieved by the male for brief periods, and the chicks hatch in 12 to 14 days and leave the nest when they are 13 to 14 days old. They climb into the vegetation around the nest to hide, where both parents feed them for two or three more weeks.
