3-11-2021 BIOPARC, VALENCIA - SOUTHERN LION (MALE) (Panthera leo ssp. melanochaita)
The Southern lion (Panthera leo melanochaita) is a subspecies inhabiting Southern and East Africa, often characterized by large males with dark, extensive manes. As Africa's largest cat, they live in social prides, with females acting as primary hunters. They are classified as Vulnerable, facing threats from habitat loss and human conflict.Physical and Biological FactsAppearance:
They are the largest of Africa's big cats, with males often weighing over 190kg (up to 225kg+ in some regions) and standing over 3 meters from nose to tail.Manes: Southern males often possess large, dark manes, though color varies from blond to black based on age and climate.Adaptability: They are found in diverse habitats, including savanna grasslands, open woodlands, and semi-arid deserts.
The Southern lion is a lion subspecies from Southern and East Africa. In this region, lion populations were referred to by several regional names, including Katanga lion, Transvaal lion, Kalahari lion, Southeast African lion, Southwest African lion, Masai lion, Serengeti lion, Tsavo lion, and Uganda lion. It has also been referred to as 'Eastern-Southern African lion', 'Southern lion', and as 'southern subspecies'.
The fur of Southern lions varies in color from light buff to dark brown. They have rounded ears and a black tail tuft. Mane color varies from sandy, tawny, isabelline, and light reddish yellow to dark brown and black. Mane length varies from short to extending to knee joints and under the belly. Lions without a mane were observed in the Tsavo area. Mane development is related to age: older males have more extensive manes than younger ones; manes continue to grow up to the age of four to five years, long after lions become reproductively mature.
Males living in the Kenyan highlands develop heavier manes than lions in the more humid and warmer lowlands of eastern and northern Kenya. White lions have occasionally been encountered in and around South Africa's Kruger National Park and the adjacent Timbavati Private Game Reserve. Their whitish fur is a rare morph caused by a double recessive allele. It has normal pigmentation in the eyes and skin. They were removed from the wild in the 1970s, thus decreasing the white lion gene pool.

3-11-2021 BIOPARC, VALENCIA - VULTURINE GUINEAFOWL (Acryllium Vulturinium)
The vulturine guinea fowl (Acryllium vulturinum) is the largest extant species of guinea fowl. Systematically, it is only distantly related to other guinea fowl genera. Its closest living relative, the white breasted guinea fowl, Agelastes meleagrides inhabit primary forests in Central Africa. It is a member of the bird family Numididae, and is the only member of the genus Acryllium. It is a resident breeder in northeast Africa, from southern Ethiopia and Somalia through Kenya and just into northern Tanzania.
The vulturine guinea fowl is a large (61–71 centimetres (24–28 in)) bird with a round body and small head. It's average weight is between 1kg to 1.6kg and it has longer wings, neck, legs and tail than other guinea fowl. The adult has a bare blue face and black neck, and although all other guinea fowl have unfeathered heads, this species looks particularly like a vulture because of the long bare neck and head.
5-11-2021 MONTE CORONA, VALENCIA - WHITE WAGTAIL (Motacilla alba)
%2020.jpg)
The White Wagtail (Motacilla alba) is a small, elegant passerine bird, a member of the family Motacillidae, which includes pipits and longclaws. This slender bird measures between 16.5 to 19 cm in length, with East Asian subspecies reaching up to 21 cm. It is characterized by its long, constantly wagging tail, a behavior that has become synonymous with the genus. Weighing an average of 25 g, the White Wagtail can live up to 12 years in the wild.
Adult White Wagtails exhibit a distinctive plumage with a combination of grey, black, and white. The bird's upper parts are generally grey, with a white face, belly, and breast. Males during the breeding season may show a darker back, and the species is known for its sharp, brisk call and more melodious song during courtship.
The White Wagtail is commonly found in open country, often in close proximity to human habitation and water sources. It shows a preference for bare areas which facilitate the sighting and pursuit of prey. This bird has adapted well to urban environments, utilizing paved areas such as parking lots for foraging.
%2021.jpg)
This species has a vast breeding range across Europe, the Asian Palearctic, parts of North Africa, and has a presence in Alaska. It is a migratory bird, with populations moving to Africa and parts of Asia during the winter. In Great Britain and Ireland, the darker subspecies known as the Pied Wagtail is more prevalent.
The White Wagtail is known for its perpetual tail wagging, a behavior that remains somewhat enigmatic but is thought to be a signal of vigilance to predators. It is a monogamous bird that defends its breeding territory with determination.
The call of the White Wagtail is a sharp "chisick," softer than that of the Pied Wagtail. Its song is more structured and is used by males to attract females rather than to mark territory.
5-11-2021 MARXUQUERA, VALENCIA - EUROPEAN GOLDFINCH (Carduelis carduelis)
%2020.jpg)
The European goldfinch, or simply goldfinch (Carduelis carduelis), is a small, vibrant passerine bird belonging to the finch family. This charming avian species is adorned with a striking red face, encircled by black markings near the eyes, and a black-and-white head. The back and flanks exhibit a warm buff or chestnut brown, while the wings are black with a prominent yellow bar. The tail is black, and the rump is a contrasting white. Males and females are similar in appearance, though the male boasts a slightly more extensive red mask.
Upon closer inspection, one can discern the male goldfinch by its larger, more vivid red mask that extends just beyond the eye. The female's red face does not reach past the eye, and her shoulder feathers are brown, as opposed to the male's black. The bill is ivory-colored, long, and pointed, and the tail is forked. Juveniles can be identified by their plain heads and greyer backs, but the yellow wing stripe is a clear indicator of their species.
The European goldfinch favors open, partially wooded lowlands and is a resident in the milder western parts of its range. In colder regions, it migrates to escape the harsh weather.
3-11-2021 BIOPARC, VALENCIA - FALSE TOMATO FROG (Dyscophus guineti)
Dyscophus guineti, the false tomato frog or the Sambava tomato frog, is a species of frog in the family Microhylidae. It is endemic to Madagascar. Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical swamps, swamps, freshwater marshes, intermittent freshwater marshes, and heavily degraded former forest. It is threatened by habitat loss.
Description The Dyscophus guineti male frogs are yellowish, and in size 60-65mm. The female frogs are red- orange often with many small reticulations, in size 90-95mm. Some of these frogs have an Odontoma which are tumors from a tooth that also contain tissue. These cause bad tooth eruption and displacement of erupted teeth.
Another aspect which concerns these frogs is the way they capture their prey using their tongues and mouth. It is based on how close their prey is to them, the way they capture it changes. If their prey is smaller and at an azimuthal location of less than 40A degrees, they will aim their heads at the prey and not their tongues. If their prey is larger and at an azimuthal location greater than 40A then they proceed to aim both their head and tongue at their prey. The process when the prey is larger is better known as hydrostatic elongation. The dysciphus guinteti also has tongue movements sperate of the lower jaw which changes their speed, momentum, and projection of their tongue in different situations.

3-11-2021 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.
2-11-2021 MONTE CORONA, VALENCIA - TAWNY COCKROACH (Ectobius pallidus)
%2020.jpg)
Ectobius pallidus, the tawny cockroach, is a species of non-cosmopolitan cockroach in the family Ectobiidae. It occurs in southern England, Belgium, France, the Netherlands, Germany, Switzerland, Italy, Spain and Portugal; in North Africa: Algeria and Tunisia. It is now known to be introduced into North America.
Subspecies include:
Ectobius pallidus chopardi Adelung, 1917
Ectobius pallidus minor Ramme, 1923
Ectobius pallidus pallidus (Turton, 1806) – type
Ectobius pallidus punctulatus (Fieber, 1853)

3-11-2021 BIOPARC, VALENCIA - GOLDEN MANTELLA FROG (Mantella aurantiaca)
%2020.jpg)
The golden mantella (Mantella aurantiaca) is a small, terrestrial frog endemic to Madagascar. It has an extremely restricted distribution in three distinct areas centered on the town of Moramanga - Beparasy and Ambohibary Communes, Torotorofotsy Wetland northwest of Andasibe, and in the area of Ambakoana. Mantella aurantiaca is one of Madagascar's most threatened amphibian species due to its limited distribution in an area under tremendous anthropogenic pressure. It may also be threatened by over-collection for the pet trade.
The golden mantella is a uniformly yellow, orange, or red frog measuring 20–26 mm. The inner leg displays red flash marks. The tympanum is visible, but small. Brightly colored skin warns predators that the frog is poisonous. It is thought that the brilliant colors exhibited by the golden mantella are an example of aposematism, warning predators of the poisonous nature of the frog.
%2021.jpg)
The golden mantella is highly seasonal in its behaviour and remains largely inactive during the winter months of May–October. During the summer, the golden mantella is commonly active during the day. They live in groups of typically twice as many males as there are females. When the rains arrive and the temperature warms, frogs emerge from hiding and use small lentic wetlands for breeding. Males often call from concealed positions near a water source. The call is a rather pleasant, repeated click. The frogs do not seem to engage in typical amplexus but rather the male only moves himself over the female's back in virtual amplexus. Eggs are laid on land in moist leaf litter near water and when rains arrive the tadpoles are washed from land into water.
The golden mantella has a diet of small invertebrates. In the wild, this mainly consists of mites, ants, flies, and collembolans. The frogs derive their skin toxins from their diet. These toxins include pumiliotoxin, allopumiliotoxin, homopumiliotoxin alkaloids, pyrrolizidines, indolizidines and quinolizidines. Although poisonous, the snake Thamnosophis lateralis and a skink of the genus Zonosaurus have been observed preying upon this species at Torotorofotsy Wetland.
%2022.jpg)
There are plans to launch a legal regulated collection program for this species.
Showings from a 2017 study found significant difference in captive vs wild golden mantella behavioral response times in captive populations vs wild populations, favoring captive populations.
The golden mantella is occasionally seen in the pet trade and kept in captivity by exotic animal collectors and zoological institutions. They are popular due to their diurnal activity, attractive coloration and relative ease to keep when settled in. Care sheets are easily found for this species. On the downside, however, the golden mantella is critically endangered, and the population is decreasing.
24-10-2021 ATTICA ZOO ATHENS, GREECE - EURASIAN SPOONBILL (Platalea leucorodia)
The Eurasian spoonbill, or common spoonbill, is a wading bird belonging to the ibis and spoonbill family Threskiornithidae. Its scientific name is Platalea leucorodia, with "Platalea" reflecting the broad, spoon-like bill and "leucorodia" originating from Greek, meaning "white heron." This species is almost unmistakable within its range, with adult breeding plumage being predominantly white, save for dark legs, a black bill with a yellow tip, and a distinctive yellow breast patch akin to that of a pelican. It also sports a crest during the breeding season.
In flight, the Eurasian spoonbill can be recognized by its outstretched neck, contrasting with the retracted necks of herons. Non-breeding adults lack the crest and breast patch, while juveniles have a paler bill and black-tipped primary flight feathers. The species is distinguishable from the African spoonbill in winter by the latter's red face and legs and absence of a crest.
Eurasian spoonbills favor extensive, shallow wetlands with muddy or fine sandy substrates. They are found in various marshes, rivers, lakes, floodplains, bogs, and mangrove swamps, indifferent to the salinity of the water. They are particularly drawn to undisturbed islets for nesting and areas with dense vegetation and scattered trees for shelter.

24-10-2021 ATTICA ZOO ATHENS, GREECE - HOODED PARROT (Psephotus dissimilis)
The hooded parrot (Psephotellus dissimilis) is a species of parrot native to the Northern Territory in Australia. It is found in savannah and open woodland and is one of two extant species in its genus that breed in termite mounds. It has declined from much of its original range.
An Australian endemic, the hooded parrot inhabits to semi-arid areas of northeast Northern Territory, and is separated from the golden-shouldered parrot by the Carpentarian faunal barrier.
Though this species has disappeared from most of its original range, it remains common in protected areas. The hooded parrot is evaluated as Least Concern on IUCN Red List of Threatened Species.
The diet consists mainly of seeds, berries and vegetables.
The hooded parrot digs cavities in termite mounds. It generally chooses conical termite mounds, only successful in flat two dimensional mounds if it digs at the edge rather than on the face of the mound. Excavation takes around three weeks. The tunnel is roughly horizontal and around 50 to 80 cm long.
Breeding takes place once or twice a year between April and August. The female lays four or five white, slightly shiny eggs that are 21 long by 19 mm wide.
The hooded parrot has a close ecological relationship with the moth species Trisyntopa neossophila. The female moth lays eggs in the parrot nesting cavity, so that the eggs hatch at the same time as the baby hooded parrots. The moth larvae live in small tunnels at the base of the cavity and emerge to eat the dark material of parrot feces, leaving the white uric acid deposits. They build a silk layer across the base of the cavity to protect themselves from chicks. They pupate in the cavity walls once the juvenile parrots leave the nest.
