2-4-2021 MONTE CORONA, VALENCIA - RING NECKED PHEASANT (Phasianus colchicus)


The common pheasant (Phasianus colchicus), ring-necked pheasant, or blue-headed pheasant, is a bird in the pheasant family (Phasianidae). The genus name comes from Latin phasianus 'pheasant'. The species name colchicus is Latin for 'of Colchis' (modern day Georgia), a country on the Black Sea where pheasants became known to Europeans. Although Phasianus was previously thought to be closely related to the genus Gallus, the genus of junglefowl and domesticated chickens, recent studies show that they are in different subfamilies, having diverged over 20 million years ago.

It is native to Asia, where it is widespread, and also to the extreme southeast of Europe in the northern foothills of the Caucasus Mountains. It has been widely introduced elsewhere as a game bird. In parts of its range, mainly in places where none of its relatives occurs such as in Europe, where it is naturalised, it is simply known as the pheasant. 


Ring-necked pheasant is both the collective name for a number of subspecies and their intergrades that have white neck rings and the name used for the species as a whole in North America.

It is a well-known gamebird, among those of more than regional importance perhaps the most widespread and ancient one in the whole world. The common pheasant is one of the world's most hunted birds; it has been introduced for that purpose to many regions and is also common on game farms, where it is commercially bred.

2-4-2021 MONTE CORONA, VALENCIA - BLUE ROCK THRUSH (MALE) (Monticola solitarius)

The blue rock thrush is a starling-sized bird, 21–23 cm (8.3–9.1 in) in length with a long slim bill. The breeding male of the nominate subspecies is unmistakable, with all blue-grey plumage apart from its darker wings. Females and immatures are much less striking, with dark brown upperparts, and paler brown scaly underparts. The male of the subspecies M. s. philippensis has rufous-chestnut plumage from the mid-breast down to the undertail. Both sexes lack the reddish outer tail feathers of rock thrush.

The male blue rock thrush sings a clear, melodious call that is similar to, but louder than the call of the rock thrush.

The European, north African and southeast Asian birds are mainly resident, apart from altitudinal movements. Other Asian populations are more migratory, wintering in sub-Saharan Africa, India and southeast Asia. This bird is a very uncommon visitor to northern and western Europe.

29-3-2021 BIOPARC, VALENCIA - DUMERIL'S BOA (Acrantophis dumerili)


Acrantophis dumerili, commonly known as Dumeril's boa, is a species of non-venomous snake in the family Boidae. The species is endemic to Madagascar. No subspecies are currently recognized.

Adults of A. dumerili usually grow to 6.5 feet (2 m) in total length (including tail) with the maximum reported to be 8 foot, 6 inches (259 cm). Males usually have longer skinnier tails, while females tend to be larger overall.


A. dumerili is found on Madagascar. The type locality given in the original description is "Amérique mérid. ?", which is later given as "?" by Jan (1863).

Along the western coast and southwestern regions of Madagascar, it is found in a semi-arid habitat that gets fairly low amounts of precipitation.

The diet of A. dumerili consists of small animals, such as birds, lizards, and small mammals, including juvenile lemurs. It is also known to prey on other snakes.


In A. dumerili sexual maturity is reached within 3 to 5 years of age. Males have anal spurs, which are used in courtship. The mating season is March through May, and the young are born some 6 to 8 months later. Ovoviviparous, females give birth to a litters of 6-28. Neonates are 12-18 inches (30–46 cm) long.

Once exported from Madagascar in great numbers, trade in A. dumerili has since been heavily restricted. The species is, however, quite prolific in captivity, and captive bred individuals are easy to find in the exotic pet trade. Though its size makes it more suited to someone experienced with large constrictors, it has a typically docile nature, and readily feeds on rats. The main concern is that it is prone to stress, which can sometimes cause it to stop eating or can contribute to other health issues.

1-4-2021 SILLA , VALENCIA - GLOSSY IBIS (Plegadis falcinellus)


The glossy ibis (Plegadis falcinellus) is a water bird in the order Pelecaniformes and the ibis and spoonbill family Threskiornithidae. The scientific name derives from Ancient Greek plegados and Latin, falcis, both meaning "sickle" and referring to the distinctive shape of the bill.

The historical name black curlew was used for the glossy ibis in Norfolk at least until the early 19th century, and this name also appears in Anglo-Saxon literature.[citation needed] Yalden and Albarella do not mention this species as occurring in medieval England.


This is the most widespread ibis species, breeding in scattered sites in warm regions of Europe, Asia, Africa, Australia, and the Atlantic and Caribbean regions of the Americas. It is thought to have originated in the Old World and spread naturally from Africa to northern South America in the 19th century, from where it spread to North America. The glossy ibis was first documented in the New World in 1817 (New Jersey). Audubon saw the species just once in Florida in 1832.

It expanded its range substantially northwards in the 1940s and to the west in the 1980s. This species is migratory; most European birds winter in Africa, and in North America birds from north of the Carolinas winter farther south. Though generally suspected to be a migratory species in India, the glossy ibis is resident in western India. Birds from other populations may disperse widely outside the breeding season. 


It is increasing in Europe, after earlier major declines in the 19th and early 20th centuries due to uncontrolled heavy hunting pressure and habitat loss. Birds which arrived in Great Britain and Ireland were routinely shot as trophies until the 1920s, when attitudes started to change. It disappeared as a regular breeding bird in Spain in the early 20th century, but with legal protection re-established itself in 1993 and has since rapidly increased with thousands of pairs in several colonies. It has also established rapidly increasing breeding colonies in France, a country with very few breeding records before the 2000s. 


However, in Italy, where illegal hunting has been a continuing problem despite legal protection since 1977, the increase in the population has been markedly lower with only 10–50 pairs breeding. An increasing number of non-breeding visitors are seen in northwestern Europe, a region where glossy ibis records historically were very rare. For example, there appears to be a growing trend for birds to winter in Britain and Ireland, with at least 22 sightings in 2010. In 2014, a pair attempted to breed in Lincolnshire, the first such attempt in Britain. The first successful breeding in Britain was a pair which fledged one young in Cambridgeshire in 2022. A few birds now spend most summers in Ireland, but there is no present evidence of breeding. In New Zealand, a few birds arrive there annually, mostly in the month of July; recently a pair bred amongst a colony of royal spoonbill. 

1-4-2021 SILLA , VALENCIA - BLACK WINGED STILT (Himantopus himantopus)


The black-winged stilt is a black and white wading bird with incredibly long legs. They live in a variety of wetlands, from marshes to coastal lagoons. They wade through the water, plucking insects from the surface.

The Black-winged stilt (Himantopus himantopus) is one of the most fascinating waders seen on the banks of the many water-bodies in our country. Proportionately the longest legged of the waders, with the exception of the flamingo, the tall, lanky, slender-necked, Blackwinged stilt presents a stark visual contrast. Its black wings and white neck and underparts give it the distinctive look of a formally dressed dinner guest! The bright red legs and red iris provide an added dash of colour. In winter both sexes are fairly similar in appearance with dabs of greyish-brown on their heads and necks. The sooty-brown wings of the female are, however, duller than those of the male, which have an added metallic, blue-green sheen. With the onset of summer the adult male sports darker spots on his head extending down to his neck.


Members of the genus Himantopus, are a very variable species, (upto eight are recognised) of which the Black-winged is one. They have an extremely broad breeding range, from temperate to tropical climates and from rain forests to deserts, spreading over Eurasia, Africa, Australia and the Americas. Most members of this family are, however, nomadic, moving as conditions change, with a few northern hemisphere populations migrating over short distances.

The Black-winged stilt is both a resident and a visitor in India. Every winter it makes its way south in small flocks and settles on the edges of marshes, lakes, rivers and tidal areas all over the Indian peninsula. In summer these flocks move northwards again, to nest in the lakes and rivers of northern India, north-west Pakistan and Afghanistan.

1-4-2021 EL SALER , VALENCIA - GREY HERON (Ardea cinerea)


The grey heron (Ardea cinerea) is a long-legged wading bird of the heron family, Ardeidae, native throughout temperate Europe and Asia, and also parts of Africa. It is resident in much of its range, but some populations from the more northern parts migrate southwards in autumn. A bird of wetland areas, it can be seen around lakes, rivers, ponds, marshes and on the sea coast. It feeds mostly on aquatic creatures which it catches after standing stationary beside or in the water, or stalking its prey through the shallows.

Standing up to 1 metre (3 ft 3 in) tall, adults weigh from 1 to 2 kg (2 to 4 lb). They have a white head and neck with a broad black stripe that extends from the eye to the black crest. The body and wings are grey above and the underparts are greyish-white, with some black on the flanks. The long, sharply pointed beak is pinkish-yellow and the legs are brown.

The birds breed colonially in spring in heronries, usually building their nests high in trees. A clutch of usually three to five bluish-green eggs is laid. Both birds incubate the eggs for around 25 days, and then both feed the chicks, which fledge when 7-8 weeks old. Many juveniles do not survive their first winter, but if they do, they can expect to live for about 5 years.

1-4-2021 EL ROMANI , VALENCIA - GREATER FLAMINGO (Phoenicopterus roseus)


The Greater flamingo (Phoenicopterus roseus) is the most widespread and largest species of the flamingo family. It was described by Peter Simon Pallas in 1811. The Greater flamingo was previously thought to be the same species as the American flamingo, but because of coloring differences of its head, neck, body, and bill, the two flamingos are now most commonly considered separate species.

Greater flamingos have an attractive coloration and appearance. Their feathers are pinkish/white, the wing coverts are red and the primary and secondary flight feathers are black. They have long pink bills with a black tip, yellow eyes and long pink legs. The male is bigger than the female, and juveniles have a gray-brown coloration, with some pink on their underparts, tail and wings, with the legs and beak being mainly brown.


The Greater flamingo inhabits Africa, the Middle East, southern Europe, and the Indian subcontinent. They occur in relatively shallow water bodies, such as saline lagoons, salt pans, large alkaline or saline lakes, and estuaries. Breeding takes place on sandbanks, mudflats, sandy or rocky islands, or open beaches.


Greater flamingos are very social. They travel in groups numbering up to thousands and they communicate by using visual and auditory cues. Greater flamingos are partially dispersive and migratory. They are traveling constantly, seeking areas with enough resources to sustain the whole flock, especially during the mating season. Greater flamingos keep their chicks together in crèches. Adults supervising crèches tend to act in a hostile way toward hatchlings if their own young are not in that crèche. Greater flamingos are diurnal, feeding during the day. Being bottom feeders, they rely on water levels that are low, and they move to new areas to find appropriate feeding conditions. They often bathe in fresh shallow water and preen their feathers to remove salt from them. They are not territorial birds but during breeding season they do defend their nests.

29-3-2021 BIOPARC, VALENCIA - FOREST BUFFALO (MALE) (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.

29-3-2021 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.

29-3-2021 BIOPARC, VALENCIA - PANTHER CHAMELEON (Furcifer pardalis)


 The panther chameleon (Furcifer pardalis) is a species of chameleon found in the eastern and northern parts of Madagascar in a tropical forest biome. Additionally, it has been introduced to Réunion and Mauritius, as well as the state of Florida within the United States.

Panther chameleons grow 16-20" (40–51 cm) long, with females typically being smaller than males. In a form of sexual dimorphism, males are more vibrantly colored than the females. Another form of sexual dimorphism is in size, it has been concluded that males are much larger and heavier than females and therefore seen as a large sex difference in body size. Coloration varies with location, and the different color patterns of panther chameleons are commonly referred to as 'locales', which are named after the geographical location in which they are found. Panther chameleons from the areas of Nosy Be, Ankify, and Ambanja are typically a vibrant blue, and those from Ambilobe, Antsiranana, and Sambava are red, green or orange. The areas of Maroantsetra and Tamatave yield primarily red specimens. Numerous other color phases and patterns occur between and within regions. Females generally remain tan and brown with hints of pink, peach, or bright orange, no matter where they are found, but there are slight differences in patterns and colors among the different color phases.

31-3-2021 GANDIA, VALENCIA - CRETAN TREE MALLOW (Malva multiflora)


This distinctive mallow with pale pink or whitish flowers is one of the few wildflowers of the Iberian Peninsula and Mediterranean region to survive the heat past May, which may be due to its ability to form deep roots that gain access to what little water remains in the soil once the summer temperatures soar.
This annual or biennial plant usually grows to between 0.3 and 1.5m in height but can sometimes reach 2m. Small Tree Mallow is also known as Cretan Mallow. Lavatera cretica is a synonym of Malva multiflora.

Small Tree Mallow, or Cretan Mallow, can be found throughout the Mediterranean region. This wildflower is also native to Britain, where is a rare find.

This member of the Mallow family of plants occurs mainly on cultivated and disturbed ground, along waysides and in waste ground.

31-3-2021 GANDIA, VALENCIA - EUROPEAN GOLDFINCH (Carduelis carduelis)


The Goldfinch is a colourful finch with a bright red face and yellow wing patch. It's a very sociable bird, often breeding in loose groups. It has a delightful twittering song and call. Their fine beaks allow them to extract otherwise inaccessible seeds from thistles and teasels. Increasingly, they are visiting bird tables and feeders. In winter, many UK Goldfinches migrate as far south as Spain.
The European goldfinch is illegally trafficked and can be found in countries worldwide, including the United States.


They attach their nests to tree twigs using spider silk.
Males and females look similar, but males have slightly larger red face masks that extend to their eyes.
They are frequent visitors to backyard feeders, especially those containing niger seeds.
They forage by hovering over plants and will occasionally feed upside down.

The European goldfinch or simply the goldfinch (Carduelis carduelis) is a small passerine bird in the finch family that is native to Europe, North Africa and western and central Asia. It has been introduced to other areas, including Australia, New Zealand and Uruguay.


The breeding male has a red face with black markings around the eyes, and a black-and-white head. The back and flanks are buff or chestnut brown. The black wings have a broad yellow bar. The tail is black and the rump is white. Males and females are very similar, but females have a slightly smaller red area on the face.

The goldfinch is often depicted in Italian Renaissance paintings of the Madonna and Child.

The average European goldfinch is 12–13 cm (4.7–5.1 in) long with a wingspan of 21–25 cm (8.3–9.8 in) and a weight of 14 to 19 g (0.49 to 0.67 oz). The sexes are broadly similar, with a red face, black and white head, warm brown upper parts, white underparts with buff flanks and breast patches, and black and yellow wings.


On closer inspection, male European goldfinches can often be distinguished by a larger, darker red mask that extends just behind the eye. The shoulder feathers are black, whereas they are brown on the female. In females, the red face does not extend past the eye. The ivory-coloured bill is long and pointed, and the tail is forked. Goldfinches in breeding condition have a white bill, with a greyish or blackish mark at the tip for the rest of the year. Juveniles have a plain head and a greyer back but are unmistakable due to the yellow wing stripe. Birds in central Asia (the caniceps group) have a plain grey head behind the red face, lacking the black and white head pattern of European and western Asian birds. Adults moult after the breeding season, with some individuals beginning in July and others not completing their moult until November. After moult birds appear less colourful, until the tips of the newly grown feathers wear away.

31-3-2021 GANDIA, VALENCIA - SPOTLESS STARLING (Sturnus unicolor)


The Spotless Starling, known scientifically as Sturnus unicolor, is a member of the starling family, Sturnidae. It bears a striking resemblance to its cousin, the Common Starling, but is distinguished by its slightly larger size, measuring 21-23 cm in length and weighing between 70-100 grams. Its plumage is a glossy, oily black, which may exhibit purple or green iridescence under bright light. Notably, during the spring and summer, its feathers are completely devoid of spots, while in winter, it sports only minuscule pale spots.

To identify the Spotless Starling, look for its longer throat feathers, which are double the length of those on the Common Starling, creating a pronounced "beard" especially visible when the bird vocalizes. Its legs are a vivid pink, and the bill color changes with the seasons: yellow with a bluish or pinkish base in summer, and a duller, often blackish hue in winter. Juveniles present a dull brown plumage, darker than their common counterparts, with a black bill and brown legs.

The Spotless Starling is quite adaptable, inhabiting a variety of open environments from farmlands and olive groves to urban areas. It thrives particularly well in open grazed holm oak woods and in cities like Gibraltar, where it is a common sight.


This bird has a more restricted range compared to the Common Starling, being native to the Iberian Peninsula, Northwest Africa, southernmost France, and the islands of Sicily, Corsica, and Sardinia. It is largely sedentary, with its population having expanded northward in recent decades.

The Spotless Starling is a sociable creature, often seen in sizeable flocks that can number up to 100,000 in the winter months. These flocks may include Common Starlings as well. It exhibits a strong, direct flight and, like its relative, walks rather than hops.

A vocal bird, the Spotless Starling is an accomplished mimic. Its calls are reminiscent of the Common Starling but are notably louder.

As a cavity-nesting species, the Spotless Starling makes its home in tree holes, buildings, and cliff crevices. It typically lays a clutch of three to five eggs.

An omnivorous bird, the Spotless Starling's diet includes a wide array of invertebrates, berries, and human-provided food scraps.

29-3-2021 BIOPARC, VALENCIA - FOREST SITATUNGA (Tragelaphus spekii ssp. gratus)


Social organization: Sitatunga are semi-social, non territorial, and sedentary. Swamps are highly productive ecosystems and sitatunga's can live at densities of 55/km^(2) or higher. Females tend to form herds and males associate together or with females until sub adult. As adults, males avoid one another.

Activity: Sitatunga's move through the swamp along established pathways. These have numerous side branches leading to feeding grounds and neighbouring riverine forest. They are active both diurnally and nocturnally and may move into marshy land at night. They typically feed at any hour in areas where they are protected. They also lie on platforms of vegetation that each animal prepares for itself by repeated circling and trampling. They also stand and ruminate in the water.

Locomotion: Sitatunga's are slow and clumsy land runners, but their plunging run works well in water. Their broad and splayed hooves keep them from sinking in soft ground as deeply as other ungulates. They are usually slow and inconspicuous, and are good swimmers.

Vocal communication: Males often bark at night, sometimes as an alarm signal, or perhaps as a way of announcing their location. Females have a single higher-pitched bark. A male following a female in a low stretch may utter a suppressed roar. (Estes, 1991)

Alchornea cordifolia, common around Lake Victoria, provides a favourite browse for sitatunga. Foraging takes place in both dry land and swamp. Sitatunga select plants in the flowering stage. They often emerge at night from swamplands to graze on nearby dry land, as well as in adjacent forests where they browse on foliage and creepers. Feeding activity is apt to be concentrated in a small area of swamp for many days at a time, then they suddenly shift to new grounds. Sitatunga feed while immersed up to their shoulders and move slowly through the vegetation. Sometimes forelegs may be immersed while hind legs are elevated. They may rear to reach flowers of tall reeds, sedges, grasses and foliage, and males have been known to break branches with their horns. When feeding on long leaves, a sitatunga wraps its tongue around a clump, pulls it into its mouth, and crops it with its incisors.
