12-2-2020 BIOPARC, VALENCIA - EURASIAN BLACKBIRD (MALE) (Turdus merula)


The Common Blackbird, Turdus merula, is a true thrush and a familiar sight in gardens and woodlands. The male is distinguished by its all-black plumage, bright yellow eye-ring, and orange-yellow bill, which darkens slightly during winter. Females and juveniles are more demure in their attire, sporting mainly dark brown feathers.

Adult males are entirely black with the exception of the yellow eye-ring and bill. Females are sooty-brown with a duller bill, and juveniles resemble females but have pale spots on their upperparts. The very young may also exhibit a speckled breast.

The Common Blackbird thrives in a variety of habitats including woodlands with dense undergrowth, gardens, parks, and hedgerows. It shows a preference for deciduous trees and areas with thick vegetation.

The Common Blackbird thrives in a variety of habitats including woodlands with dense undergrowth, gardens, parks, and hedgerows. It shows a preference for deciduous trees and areas with thick vegetation.

This species is widespread across Europe, western Asia, and North Africa. It has also been introduced to Australia and New Zealand. Its range varies from resident populations in the milder regions to partially or fully migratory populations in areas with more severe winters.


The Common Blackbird is territorial, especially during breeding season, with males displaying distinctive threat behaviors to ward off rivals. Outside of breeding season, they can be more sociable, often forming small flocks. The species is known for its adaptability to urban environments, where it may overwinter more readily than in rural settings.

The male's song is a melodious and fluted warble, often heard from elevated perches during the breeding season. The Common Blackbird also has a repertoire of calls including a sharp "seee" when agitated and a "pook-pook-pook" to signal ground predators.

Monogamous by nature, the Common Blackbird builds a neat, cup-shaped nest, often in dense shrubbery. The female lays three to five bluish-green eggs adorned with reddish-brown blotches. Both parents are involved in feeding the altricial chicks until they fledge.

An omnivore, the Common Blackbird forages primarily on the ground for insects, earthworms, seeds, and berries. It is adept at pulling earthworms from the soil and foraging through leaf litter for other invertebrates.

2020 GALAPPAGOS, ECUADOR - VAMPIRE GROUND FINCH (Geospiza septentrionalis)


The Vampire Ground Finch (Geospiza septentrionalis) is a rare, small bird found only on Wolf and Darwin Islands in the Galápagos, known for feeding on the blood of Nazca and blue-footed boobies. They use their sharp beaks to peck at the base of feathers on seabirds, drinking the blood as an adaptation to survive in resource-poor environments. 


Key Facts About the Vampire Ground Finch: 
Unique Behavior: The finch drinks blood, a behavior thought to have evolved from feeding on parasites found on the boobies. 

Limited Range: They are endemic to only two remote, northern Galápagos Islands: Wolf and Darwin.

Diet: While known for drinking blood, their diet mainly consists of seeds, invertebrates, and cactus nectar during the wet season. They also eat eggs, rolling them to break them open.

Evolutionary Adaptation: This blood-drinking behavior developed as an adaptation to the arid, resource-poor environment, helping them survive.


Physical Appearance: They have a sharp, thin, and pointed beak. Males are generally sooty-black, while females are brown with grey streaks.

Conservation Status: The species is listed as Vulnerable on the IUCN Red List, with a small, restricted population estimated at 250–999 mature individuals.

Threats: Major threats include the introduced parasitic fly Philornis downsi and potential habitat changes, which can impact their population.

Similarities to Other Species: Formerly considered a subspecies of the Sharp-beaked Ground Finch, they are now recognized as a distinct species. 

12-2-2020 BIOPARC, VALENCIA - COMMON OSTRICH (FEMALE) (Struthio camelus)


The common ostrich (Struthio camelus) is the world's largest and heaviest bird, standing up to 9 feet tall and weighing up to 320 pounds. Found in African savannas, they are flightless but can run at speeds over 40 mph (70 km/h), using powerful two-toed legs for defense. They lay the largest eggs, which can weigh up to 3 pounds. 

Here are the key facts about the common ostrich:

Size and Speed: Ostriches are the fastest-running birds, capable of reaching speeds of 43–45 mph ( km/h) and sprinting up to 16 feet in a single stride. They weigh between 200 and 320 pounds (90-145 kg) and stand 6–9 feet tall.


Physical Characteristics: They have massive, powerful legs, long necks, and the largest eyes of any land animal—roughly 2 inches in diameter. They are the only birds with two toes, designed for running and kicking. Males have black and white feathers, while females are brown.

Diet: As omnivores, they consume plants, roots, seeds, insects, and small reptiles. They often swallow pebbles and sand to help grind food in their gizzard.


Lifespan: In the wild, they typically live to be about 30-40 years old, while in captivity, they can live up to 50 years.

Predators and Defense: While adult ostriches can defend themselves against lions, hyenas, and leopards with a powerful kick, they are most vulnerable to predators when young.

Common Misconceptions: Ostriches do not bury their heads in the sand; they lay their heads flat on the ground to blend in with the landscape when threatened.

Unique Features: They use their wings (which are useless for flight) as rudders to change direction while running and for shade. 

12-2-2020 BIOPARC, VALENCIA - GRANT'S ZEBRA (Equus quagga ssp. boehmi)


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 and others across central Africa.

This subspecies is distributed in Zambia west of the Luangwa river west to Kariba, Katanga Province of the Democratic Republic of the Congo, north to the Kibanzao Plateau, and in Tanzania north from Nyangaui and Kibwezi into southwestern Kenya as far as Sotik. It can also be found in eastern Kenya and east of the Great Rift Valley into southernmost Ethiopia. It occurs as far as the Juba River in Somalia.

Duncan (1992) recognized the Upper Zambezi zebra (Equus quagga zambeziensis Prazak, 1898[2]). Groves and Bell (2004) came to the conclusion that the zebras from West Zambia and Malawi cannot be distinguished cranially and that they differ only slightly from other northern plains zebras. The minor size difference does not justify a separate subspecific status for the Upper Zambezi zebra. Therefore, they combine these zebras with Grant's zebra (Equus quagga boehmi).


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 led by a single stallion. Grant’s zebras typically live 20 years.

Recent civil wars in the Congo, Rwanda, Somalia, Sudan, Ethiopia, and Uganda have caused dramatic declines in all wildlife populations, including those of Grant’s zebra.[citation needed] It is now extirpated from Burundi. Civil war in Angola during much of the past 25 years has devastated its wildlife populations, including its once-abundant plains zebra, and destroyed the national parks administration and infrastructure. Consequently, Grant's zebra is probably extinct or nearly so in Angola, although confirmation will have to wait until future surveys are conducted.

16-2-2020 MONTE CORONA, VALENCIA - HOUSE SPARROW (MALE) (Passer domesticus)


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

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

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

16-2-2020 MONTE CORONA, VALENCIA - CATALONIA WALL LIZARD (Podarcis liolepis)


Podarcis liolepis, the Columbretes wall lizard or Catalan wall lizard, is very similar to the other lizards in the genus Podarcis. This species was formerly described as a subspecies of the Iberian wall lizard, but has now been elevated to species status. These are slender lizards with long tails, narrow tapered heads and long thin toes, and stout legs. Colours are variable, although generally grey-brown. Often very subtle spots and stripes along the back and flanks can be seen and these can be more distinguished in the female. The underside is a much lighter cream or beige with sometimes a reddish tint. Adults grow 15–20 cm in length from the nose to tip of the tail. Body length can be a little as one third of the total body length, the tail making up the other two thirds.

19-2-2020 EL SALER, VALENCIA - GREATER FLAMINGO (Phoenicopterus roseus)


The greater flamingo, Phoenicopterus roseus, stands as the most widespread and largest member of the flamingo family. This majestic bird is adorned with pinkish-white plumage, save for the red wing coverts and contrasting black primary and secondary flight feathers. The bill is a striking pink with a black tip, and the legs are a uniform pink, completing the iconic look of this species.


Adult greater flamingos can be identified by their height, ranging from 110 to 150 cm, and their weight between 2 and 4 kg. The largest males can reach up to 187 cm tall and weigh 4.5 kg. Observers should note the distinctive coloration, with the majority of the body being pinkish-white, red wing coverts, and black flight feathers. The pink bill with a black tip and entirely pink legs are also key identification features. The call of the greater flamingo is reminiscent of a goose-like honking.


Greater flamingos favor mudflats and shallow coastal lagoons with saline water, where they can be seen stirring the mud with their feet in search of food.

This species is common in the Old World, with a range that includes Northern and Sub-Saharan Africa, the Indian Subcontinent, the Middle East, the Levant, and Southern Europe. Notably, they are found in coastal regions and along water bodies such as the Nile River, the Persian Gulf, the Gulf of Aden, the Red Sea, and the Mediterranean.


Greater flamingos are social birds, often found in large flocks. They feed with their heads down, filtering out sustenance from the water with their specially adapted bills. During the breeding season, these birds engage in a fascinating display of spreading uropygial secretions over their feathers to enhance their color, a behavior likened to applying "make-up."

The vocalization of the greater flamingo is a distinctive honking, similar to that of a goose, which can be heard over considerable distances.

The species lays a single chalky-white egg on a mud mound, a typical breeding behavior for flamingos.

Greater flamingos feed on a diet that includes small shrimp, seeds, blue-green algae, microscopic organisms, and mollusks. They filter their food from the water with their downward-facing heads and movable upper jaws.

The IUCN Red List classifies the greater flamingo as Least Concern, indicating a stable population. However, they face threats from habitat encroachment and pollution in their water supplies.

In the voice of David Attenborough, one might say: "The greater flamingo, with its elegant stature and vibrant hues, is a testament to the wonders of the avian world. As it sifts through the shallows, one cannot help but be captivated by its grace and the delicate balance it maintains within its ecosystem."

19-2-2020 MONTE CORONA, VALENCIA - MEDITERRANEAN SPINY FALSE WOLF SPIDER (Zoropsis spinimana)



Tuesday, 18 February 2020

12-2-2020 BIOPARC, VALENCIA - RUPPELL'S VULTURE (Gyps rueppelli)


Rüppell's vulture (Gyps rueppelli) is a large bird and its name comes from the 19th-century German zoologist and explorer Eduard Rüppell. It is native to the Sahel region and East Africa and its current population is decreasing due to loss of habitat, incidental poisoning, and other factors. Rüppell's vulture is considered to be the highest-flying bird, with confirmed evidence of a flight at an altitude of 11,300 m (37,000 ft) above sea level.

Both sexes of this species look alike: mottled brown or black overall with a whitish-brown underbelly and thin, dirty-white fluff covering the head and neck. The base of the neck has a white collar, the eye is yellow or amber, and the crop patch is deep brown. The head does not have feathers. This is an adaptation that occurred because of the Rüppell vulture's tendency to stick its head inside of its prey when eating. Without the adaptation, feeding would become extremely messy.

Rüppell's vultures are diurnal and very social birds, roosting, nesting, and feeding in large flocks. Like most vultures, they are silent, except when at their nesting ground or foraging around a carcass. They spend much of their time flying, gliding with wings held level, or using slow, powerful wing beats. They often fly at great altitudes, using strong winds or thermals for more efficient soaring. These vultures locate food by sight only, and once they see a carcass they swoop down, land a little way off, and then bound forward with wings spread and their long neck outstretched. Fights with other vultures are common as the birds struggle to get their meal, their necks often turning deep red from aggression as they hiss, grunt, and chatter at their opponent.

12-2-2020 BIOPARC, VALENCIA - HAMERKOP (Scopus umbretta)


The hamerkop (Scopus umbretta), also called the umbrette, is a medium-sized bird. It is the only living species in the genus Scopus and the family Scopidae. The species and family was long thought to sit with the Ciconiiformes but is now placed with the Pelecaniformes, and its closest relatives are thought to be the pelicans and the shoebill. The shape of its head with a long bill and crest at the back is reminiscent of a hammer, which has given this species its name after the Afrikaans word for hammerhead. It is a medium-sized waterbird with brown plumage. It is found in mainland Africa, Madagascar and Arabia, living in a wide variety of wetlands, including estuaries, lakesides, fish ponds, riverbanks, and rocky coasts. The hamerkop is a sedentary bird that often shows local movements.

12-2-2020 BIOPARC, VALENCIA - AFRICAN FISH EAGLE (Haliaeetus vocifer)

                                      

The African fish eagle, or African sea eagle, is a majestic bird of prey that graces the skies of sub-Saharan Africa. It is a symbol of national pride, being the national bird of Malawi, Namibia, Zambia, and Zimbabwe. This raptor is known for its striking appearance, with a mostly brown body contrasted by a snow-white head, breast, and tail. The face is featherless and a vivid yellow, matching the color of its formidable, hooked beak, tipped in black. The African fish eagle's eyes are a deep, dark brown, and its powerful black wings carry it effortlessly over open waters.

Adult African fish eagles are unmistakable with their white heads and chests, brown bodies, and large black wings. Females are larger than males, with wingspans reaching up to 2.4 meters, compared to the 2-meter span of males. Juveniles can be identified by their overall brown plumage and paler eyes. The species exhibits sexual dimorphism, with females being heavier, weighing between 3.2 to 3.6 kilograms, while males weigh between 2.0 to 2.5 kilograms.


These eagles are typically found near freshwater lakes, reservoirs, rivers, and sometimes along coastlines at river mouths or lagoons. They thrive in a variety of habitats, including grasslands, swamps, marshes, tropical rainforests, and even desert-bordering coastlines.

The African fish eagle is indigenous to sub-Saharan Africa, with a presence in most areas south of the Sahara Desert. It is commonly seen in regions like the Orange River, the Okavango Delta, and around Lake Victoria and other large Rift Valley lakes.

The African fish eagle is known for its iconic, evocative call, which many consider the essence of Africa. It is a territorial bird, often seen perched high in a tree, surveying its domain. When hunting, it exhibits remarkable prowess, swooping down to snatch fish from the water with its taloned feet.

The call of the African fish eagle is a high-pitched and clear "weee-ah, hyo-hyo" or "heee-ah, heeah-heeah," with the male's call being particularly shrill.


Breeding occurs during the dry season, with pairs believed to mate for life. They maintain and reuse multiple nests, which can grow quite large over time. The female lays one to three eggs, primarily white with reddish speckles, and both parents share incubation duties. Chicks fledge at around 70 to 75 days old and remain dependent on their parents for up to three months.

The African fish eagle primarily feeds on fish, which it catches by swooping from a perch. It has specialized structures on its toes called spiricules to help grasp slippery prey. While fish are the mainstay of its diet, it also consumes waterbirds, small turtles, baby crocodiles, frogs, insects, and occasionally mammals. It is also known to engage in kleptoparasitism, stealing prey from other birds.


The African fish eagle is classified as Least Concern by the IUCN, with an estimated population size of around 300,000 individuals and a wide distribution area.

The African fish eagle may be superficially similar to the bald eagle, but they are found on different continents and can be distinguished by their calls and habitat preferences.

Mummified African fish eagles have been discovered at the Necropolis at Elkab, indicating the bird's significance in ancient cultures.

12-2-2020 BIOPARC, VALENCIA - DAMA GAZELLE (Nanger dama)


The dama gazelle (Nanger dama), also known as the addra gazelle or mhorr gazelle, is a species of gazelle. It lives in Africa, in the Sahara desert and the Sahel. A critically endangered species, it has disappeared from most of its former range due to overhunting and habitat loss, and natural populations only remain in Chad, Mali, and Niger. Its habitat includes grassland, shrubland, semi-deserts, open savanna and mountain plateaus. Its diet includes shrubs, herbs, grasses, leaves (especially Acacia leaves), shoots, and fruit.

In Niger, the dama gazelle has become a national symbol. Under the Hausa name meyna or ménas, the dama gazelle appears on the badge of the Niger national football team, who are popularly called the Ménas.


The dama gazelle is white with a reddish-brown head and neck. Both sexes usually have medium-length ringed horns curved like an "S". Males' horns are about 35 cm (14 in) long, while females' horns are much shorter. The head is small with a narrow muzzle, and the eyes are relatively large. It has a longer neck and longer legs than most gazelles. It is between 90 and 95 cm (35 and 37 in) tall at the shoulder, weighs between 35 and 75 kg (77 and 165 lb), and has a lifespan up to 12 years in the wild or 18 in captivity. A few days following birth, dama young are strong enough to follow the herd, and after a week, they are able to run as fast as the adults. The dama gazelle is considered the largest species of gazelle, with incredibly long legs, which provide extra surface area to dissipate heat, one of the many ways it stays cool in its hot desert environment. It also tends to need more water than some of its desert relatives, but it can withstand fairly long periods of drought. Unlike many other desert mammals, the dama gazelle is a diurnal species, meaning it is active during the day. Always on the alert, the dama gazelle uses a behavior called pronking to warn herd members of danger. Pronking involves the animal hopping up and down with all four of its legs stiff, so that its limbs all leave and touch the ground at the same time. Males also establish territories, and during breeding season, they actively exclude other mature males. They mark their territories with urine and dung piles and secretions from glands near their eyes.


The Dama gazelle does not need a lot of water, but it needs more than other desert animals. It is not as resistant and perishes from a lack of water during the drought season. The environment has become ill-suited for it. Habitat pressure from pastoral activity is another reason for decline, as are introduced diseases from livestock.

Another reason for the decline of the dama gazelle is habitat destruction. Humans cut down the branches of the trees on which this gazelle feeds. As a result, the trees die and the gazelle cannot eat. Human threats are the most dangerous of threats to the dama gazelle. The main reason this species of gazelle is endangered is because of mechanized hunting; hunters using vehicles increase its decline. Civil unrest, for instance in Sudan, also negatively affects the life of the dama gazelle. Since the gazelle is already having a hard time surviving, these conditions have made its habitat unsuitable. A potential threat the dama gazelle faces is tourism. Tourists want to take pictures of this endangered species, and in doing so, may be perceived as a threat, especially during the hot season. Gazelles will run away from perceived danger, and in the hot season may overheat and die of stress.


The dama gazelle's historical range included the desert and arid zones of Chad (eastern), and the Darfur and Kordofan Provinces of Sudan. Due to wars in their range, habitat destruction, desertification, overhunting, and human and livestock population expansion, they are now extremely rare, occurring only as vagrants or in pockets

The life span of the dama gazelle is unknown in the wild. In human care, individual males have lived up to 15 years and individual females have lived up to 19 years.

Dama gazelles obtain most of their water from the plants they consume. Their diet includes various desert shrubs and acacias, along with rough desert grasses.

At the Zoo, they eat orchard grass hay and alfalfa hay — about a flake each per day. In addition they eat roughly 2.5 pounds of herbivore pellet per day, with leaf eater biscuits and browse as treats.

12-2-2020 BIOPARC, VALENCIA - ADDAX (MALE) (Addax nasomaculatus)


In its tenth anniversary year, BIOPARC Valencia is taking another step in its conservation efforts for the most threatened species. This time, it is joining the important European Endangered Species Programme (EEP) for the unique Addax antelope ( Addax nasomaculatus ), which is listed as critically endangered on the International Union for Conservation of Nature (IUCN) Red List , with fewer than 100 mature individuals estimated to remain in the wild. The arrival of two females from Nuremberg and Hanover (Germany) is the first step towards establishing a breeding group and also introduces a new species to the park's animal collection. These two young females, born in 2016 and 2017, will be on display in the Savannah area after an acclimatization period in their indoor enclosure. 


This African species is the largest desert ungulate , a rounded antelope with long legs and a straight profile, distinguished by its large, vertically growing horns, present in both sexes, which curl in a spiral pattern. Also known as the "white antelope" due to the color of its coat, which darkens to grayish and brownish tones in winter, it has a characteristic white "X"-shaped mask that contrasts with its dark forehead. It is not a fast runner, making it easy prey for quicker predators such as lions, cheetahs, leopards, caracals, hyenas, and servals (which particularly prey on calves).


Adapted to the most arid and extreme terrains, the Addax inhabited the deserts of North Africa , from vast sand dune systems to compacted desert plains. They could go months without water and even years without drinking, obtaining moisture only from the plants they ate. Their acclimatization to survive in these inhospitable areas also allowed the Addax to allow their body temperature to rise during the day and lower during the cool of the night without losing water. Their nasal passage cooled arterial blood as it flowed through the nasal membrane before reaching the brain, protecting this vital organ from overheating.

12-2-2020 BIOPARC, VALENCIA - COMMON DWARF MONGOOSE (Helogale parvula)


The common dwarf mongoose ranges from East to southern Central Africa, from Eritrea and Ethiopia to the provinces of Limpopo and Mpumalanga in the Republic of South Africa. It inhabits primarily dry grassland, open forests and bushland up to an elevation of 2,000 m (6,600 ft). It is especially common in areas with many termite mounds, its favorite sleeping place. It avoids dense forests and deserts.

The common dwarf mongoose is a diurnal animal. It is a highly social species that lives in extended family groups of two to thirty 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 from predators.

Young mongooses attain sexual maturity by one year of age but delay dispersal, with males usually emigrating (in the company of their brothers) at 2–3 years old. Dispersing males may join other established groups, either as subordinates or by ousting the resident males, or they may found new groups with unrelated dispersing females. In contrast, females normally remain in their home group for life, queuing for the dominant position. They will, however, emigrate to found a new group if they lose their place in the hierarchy to a younger sister.

12-2-2020 BIOPARC, VALENCIA - GREAT WHITE PELICAN (Pelecanus onocrotalus)

The great white pelican, known scientifically as Pelecanus onocrotalus, is a gargantuan bird, surpassed in size only by its cousin, the Dalmatian pelican. With a body length ranging from 140 to 180 cm and a wingspan stretching from 226 to 360 cm, it is one of the largest flying birds. The pelican's bill is an impressive 28.9 to 47.1 cm long, colored in hues of pink and yellow, and is accompanied by a pale-yellow gular pouch. Males are generally larger than females and exhibit a pronounced sexual dimorphism, with males averaging more than 30% heavier than females.

Adult great white pelicans are predominantly white with black flight feathers and a faint pink tinge on the neck. The bill is bluish-grey with a red tip and a yellowish gular pouch. During the breeding season, males display pinkish facial skin, while females exhibit a more orangey hue. Juveniles are distinguishable by their darker, brownish underparts and patterned underwings. 

These pelicans favor shallow, warm freshwater environments, such as lakes, swamps, and lagoons, often with dense reed beds nearby for nesting. They are also found in coastal estuarine areas and occasionally at elevations up to 1,372 m in East Africa and Nepal.

12-2-2020 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.


Chimpanzees are highly intelligent, social great apes native to African forests and savannas, sharing roughly 98%–99% of their DNA with humans. Known for using tools, having complex emotional lives, and living in fission-fusion communities, they are our closest living relatives. They are endangered, with populations threatened by habitat loss and hunting. 
Key Facts About Chimpanzees
Intelligence & Tools: Chimpanzees are among the most intelligent species, known for using sticks to "fish" for termites and leaves to soak up water. They can recognize themselves in mirrors, a sign of self-awareness.

12-2-2020 BIOPARC, VALENCIA - CAPE PORCUPINE (Hystrix africaeaustralis)


The Cape porcupine (Hystrix africaeaustralis), Cape crested porcupine or South African porcupine, is a species of Old World porcupine native to central and southern Africa.

Cape porcupines are the largest rodents in Africa and also the world's largest porcupines. Cape porcupines are amongst the largest living rodents in the world; a few other rodents appear to be larger in body mass such as the capybara and the Eurasian and North American beavers. They are similar in appearance to, the slightly smaller and close relatives, the crested porcupines. They can most easily be distinguished from them by the presence of a band of short white spines along the midline of the rump. Indian porcupines are almost the same size on average as well, being slightly heavier on average than crested porcupine but slightly lighter than Cape porcupines. 


Cape porcupines measure 63 to 81 centimetres (25 to 32 inches) long from the head to the base of the tail, with the tail adding a further 11–20 centimetres (4.3–7.9 inches). They weigh from 10 to 24 kilograms (22 to 53 pounds), with exceptionally large specimens weighing up to 30 kg (66 lb); males and females are not significantly different in size. The average weight of males from Zimbabwe was 16.9 kg (37 lb) and while the average for females there was 18.4 kg (41 lb) while in the Orange river valley of South Africa males averaged 12.3 kg (27 lb) and females averaged 13 kg (29 lb).

They are heavily-built animals, with stocky bodies, short limbs, and an inconspicuous tail. The body is covered in long spines up to 50 centimetres (20 in) in length, interspersed with thicker, sharply pointed, defence quills up to 30 centimetres (12 in) long, and with bristly, blackish or brownish fur. The spines on the tail are hollow, and used to make a rattling sound to scare away predators. An erectile crest of long, bristly hairs runs from the top of the head down to the shoulders. The spines and quills cover the back and flanks of the animal, starting about a third of the way down the body, and continuing onto the tail. The quills have multiple bands of black and white along their length, and grow from regularly spaced grooves along the animal's body; each groove holding five to eight quills. The remainder of the animal, including the undersides, is covered with dark hair.

The eyes and ears are relatively small, and the mobile whiskers are short. The feet have five clawed toes, although the first toes on the forefeet are vestigial. Females have two pairs of teats.

12-2-2020 BIOPARC, VALENCIA - VERREAUX'S EAGLE OWL (Bubo lacteus)


Verreaux's eagle-owl (Ketupa lactea), also commonly known as the milky eagle owl or giant eagle owl, is a member of the family Strigidae. This species is widespread in sub-Saharan Africa. A member of the genus Ketupa, it is the largest African owl, measuring up to 66 cm (26 in) in total length. This eagle-owl is a resident primarily of dry, wooded savanna. Verreaux's eagle-owl is mainly grey in color and is distinguishable from other large owls by its bright pink eyelids, a feature shared with no other owl species in the world.


Verreaux's eagle-owl is a highly opportunistic predator equipped with powerful talons. Just over half of its known diet is composed of mammals but equal or even greater numbers of birds and even insects may be hunted locally, along with any other appropriately sized prey that is encountered. This species is considered of Least Concern by IUCN as it occurs over a wide range and has shown some adaptability to human-based alterations and destruction of habitat and adaptability to diverse prey when a primary prey species declines in a region. As a large, highly territorial species of owl, it does, however, occur at fairly low densities and some regional declines have been reported.


Verreaux's eagle-owl is found through most of sub-Saharan Africa, though it is absent from most of the deep rainforests. The species is found at the highest densities in eastern and southern Africa. As this species avoids primary forests, it is found very spottily in west Africa. Their western distribution includes The Gambia, Senegal, Guinea and Sierra Leone.

Eastward from those countries to the Central African Republic, the species is distributed in a narrow transitional zone between the Sahara and rainforests. Seemingly isolated populations occur in central Nigeria and central Mali. In south-western Africa, they range up to as far north as the southern parts of the Republic of the Congo and the Democratic Republic of the Congo, through most of Namibia (excluding the coastal regions) and northern South Africa. In east Africa, their distribution is more or less continuous from southern Sudan, Eritrea and inland Somalia down to South Africa as far as the region of the city of Durban.

12-2-2020 BIOPARC, VALENCIA - PYGMY HIPPOPOTAMUS (Choeropsis liberiensis)


The pygmy hippopotamus or pygmy hippo (Choeropsis liberiensis) is a small hippopotamid which is native to the forests and swamps of West Africa, primarily in Liberia, with small populations in Sierra Leone, Guinea, and Ivory Coast. It has been extirpated from Nigeria and possibly Guinea-Bissau.

The pygmy hippopotamus is reclusive and nocturnal. It is one of only two extant species in the family Hippopotamidae, the other being its much larger relative, the common hippopotamus (Hippopotamus amphibius) or Nile hippopotamus. The pygmy hippopotamus displays many terrestrial adaptations, but like the common hippopotamus, it is semiaquatic and relies on water to keep its skin moist and its body temperature cool. Behaviors such as mating and giving birth may occur in water or on land. The pygmy hippopotamus is herbivorous, feeding on ferns, broad-leaved plants, grasses, and fruits it finds in the forests.


A rare nocturnal forest creature, the pygmy hippopotamus is a difficult animal to study in the wild. Pygmy hippos were unknown outside West Africa until the 19th century. Introduced to zoos in the early 20th century, they breed well in captivity and the vast majority of research is derived from zoo specimens.

The survival of the species in captivity is more assured than in the wild; in a 2015 assessment, the International Union for Conservation of Nature estimated that fewer than 2,500 pygmy hippos remain in the wild.

Pygmy hippos are primarily threatened by loss of habitat, as the forests are logged and converted to farm land, and are also vulnerable to poaching, hunting for bushmeat, natural predators and war. Pygmy hippos are among the species illegally hunted for food in Liberia.


Like the common hippopotamus, the pygmy hippopotamus emerges from the water at dusk to feed. It relies on game trails to travel through dense forest vegetation. It marks trails by vigorously waving its tail while defecating to further spread its feces. The pygmy hippopotamus spends about six hours a day foraging for food.

Pygmy hippos are herbivorous. They do not eat aquatic vegetation to a significant extent and rarely eat grass because it is uncommon in the thick forests they inhabit. The bulk of a pygmy hippo's diet consists of herbs, ferns, broad-leaved plants, herbaceous shoots, forbs, sedges and fruits that have fallen to the forest floor. The wide variety of plants pygmy hippos have been observed eating suggests that they will eat any plants available. This diet is of higher quality than that of the common hippopotamus.

17-2-2020 SALEM, VALENCIA - PINE PROCESSIONARY CATERPILLAR (Thaumetopoea pityocampa)


The pine processionary (Thaumetopoea pityocampa) is a moth of the subfamily Thaumetopoeinae in the family Notodontidae, known for the irritating hairs of its caterpillars, their processions, and the economic damage they cause in coniferous forests. The species was first described scientifically by Michael Denis and Ignaz Schiffermüller in 1775, though it was known to the ancients, with remedies described by Theophrastus, Dioscorides and Pliny the Elder. Its processionary behaviour was described in 1916 by the French entomologist Jean-Henri Fabre. It is one of the most destructive species to pines and cedars in Central Asia, North Africa and southern Europe.

The species is notable for the behaviour of its caterpillars, which overwinter in tent-like nests high in pine trees, and which proceed through the woods in nose-to-tail columns, protected from predators by their severely irritating hairs.

The species is one of the few insects where the larva develops in winter in temperate zones. Global warming is causing the species to affect forests progressively further north. The urticating hairs of the caterpillar larvae cause harmful (and in some cases allergic) reactions, in humans and other mammals.

17-2-2020 SALEM, 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 and the United Kingdom 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 the latter's larger size and black band at the tip of the 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 (about 1800), North America (1860s), Hawaii (1897), New Zealand (1930), and Australia (1937), as a result of accidental introductions.
