4-1-2016 HONG KONG - STRAW HEADED BULBUL (Pycnonotus zeylanicus)
The straw-headed bulbul (Pycnonotus zeylanicus) is a species of songbird in the bulbul family, Pycnonotidae. It is found from the Malay Peninsula to Borneo. Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical mangrove forest, subtropical or tropical moist shrubland, arable land, plantations, and rural gardens. It is threatened by habitat loss and poaching.
The straw-headed bulbul is prized for its singing ability and is a highly sought-after species by bird enthusiasts in Southeast Asia, especially Indonesia. This trade is causing population reductions across the species' range and is a major barrier to its conservation. Trapping has been facilitated in recent years by the spread of logging roads across its forest habitat. Due to this, the straw-headed bulbul was uplisted from endangered to critically endangered on the IUCN Red List in 2018.
11-10-2015 VILLALONGA RESERVOIR - EURASIAN REED WARBLER (Acrocephalus scirpaceus)
%2010.jpg)
The Reed Warbler is a plain unstreaked warbler. It's warm brown on top and beige underneath. A summer visitor to breed in the UK, the largest concentrations are East Anglia and along the south coast. There are relatively few breeding in Scotland and Ireland. It spends winters in Africa.
The Reed Warbler is a bird of reedbeds, where its rhythmic song can be heard from April to September.
A recent colonist to southern Scotland, the Reed Warbler is largely confined to reedbeds and riverside reed fringes of England, Wales and eastern parts of the island of Ireland. The Reed Warbler is double brooded, laying two clutches of eggs during late spring and midsummer. It is a common host species of the Cuckoo.
UK Reed Warbler numbers increased in the latter part of the 20th century, stabilising in the early-2000s. Most Reed Warblers leave the Britain & Ireland by mid September to spend the winter in Africa, south of the Sahara Desert.
15-10-2015 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 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.
14-10-2015 VALENCIA BIOPARC - RING TAILED LEMUR (Lemur catta)
The ring-tailed lemur (Lemur catta) is a medium- to larger-sized strepsirrhine (wet-nosed) primate, and the most internationally-recognized lemur species, owing to its long, black-and-white, ringed tail. It belongs to Lemuridae, one of five lemur families, and is the only member of the Lemur genus. Like all lemurs, it is endemic to the island of Madagascar, where it is endangered. Known locally in Malagasy as maky ([makʲ] ⓘ, spelled maki in French) or hira, it ranges from gallery forests to spiny scrub in the southern regions of the island. It is omnivorous, as well as the most adapted to living terrestrially of the extant lemurs.
The ring-tailed lemur is highly social, living in groups of up to 30 individuals. It is also a female-dominant species, a commonality among lemurs. To keep warm and reaffirm social bonds, groups will huddle together. Mutual grooming is another vital aspect of lemur socialization (as with all primates), reaffirming social and familial connections, while also helping rid each other of any potential insects. Ring-tailed lemurs are strictly diurnal, being active exclusively during daylight hours. Due to this lifestyle, they also sunbathe; the lemurs can be observed sitting upright on their tails, exposing their soft, white belly fur towards the sun. They will often also have their palms open and eyes gently closed. Like other lemurs, this species relies strongly on their sense of smell, and territorial marking, with scent glands, provides communication signals throughout a group’s home range. The glands are located near the eyes, as well as near the anus. The males perform a unique scent-marking behavior called spur-marking, and will participate in stink fights by dousing their tails with their pheromones and “wafting” it at opponents. Additionally, lemurs of both sexes will scent-mark trees, logs, rocks or other objects by simply rubbing their faces and bodies onto it, not unlike a domestic cat.
As one of the most vocal primates, the ring-tailed lemur uses numerous vocalizations, including calling for group cohesion and predator alarm calls. Experiments have shown that the ring-tailed lemur, despite the lack of a large brain (relative to simiiform primates), can organize sequences, understand basic arithmetic operations, and preferentially select tools based on functional qualities.
Despite adapting to and breeding easily under captive care (and being the most popular species of lemur in zoos worldwide, with more than 2,000 captive-raised individuals), the wild population of ring-tailed lemur is listed as endangered by the IUCN Red List, due to habitat destruction, local hunting for bushmeat and the exotic pet trade. As of early 2017, the population in the wild is believed to have crashed to as low as 2,000 individuals due to these reasons, making them far more critically endangered. Local Malagasy farmers and logging industries frequently make use of slash and burn deforestation techniques, with smoke being visible on the horizon on most days in Madagascar, in an effort to accommodate livestock and to cultivate larger fields of crops.
Endemic to southern and southwestern Madagascar, the ring-tailed lemur ranges further into highland areas than other lemurs. It inhabits deciduous forests, dry scrub, montane humid forests, and gallery forests (forests along riverbanks). It strongly favors gallery forests, but such forests have now been cleared from much of Madagascar in order to create pasture for livestock. Depending on location, temperatures within its geographic range can vary from −12 °C (10 °F)[24] at Andringitra Massif to 48 °C (118 °F) in the spiny forests of Beza Mahafaly Special Reserve.
This species is found as far east as Tôlanaro, inland towards the mountains of Andringitra on the southeastern plateau, among the spiny forests of the southern part of the island, and north along the west coast to the town of Belo sur Mer. Historically, the northern limits of its range in the west extended to the Morondava River near Morondava. It can still be found in Kirindy Mitea National Park, just south of Morondava, though at very low densities. It does not occur in Kirindy Forest Reserve, north of Morondava. Its distribution throughout the rest of its range is very spotty, with population densities varying widely.
The ring-tailed lemur can be easily seen in five national parks in Madagascar: Andohahela National Park, Andringitra National Park, Isalo National Park, Tsimanampetsotse National Park, and Zombitse-Vohibasia National Park. It can also be found in Beza-Mahafaly Special Reserve, Kalambatritra Special Reserve, Pic d'Ivohibe Special Reserve, Amboasary Sud, Berenty Private Reserve, Anja Community Reserve, and marginally at Kirindy Mitea National Park. Unprotected forests that the species has been reported in include Ankoba, Ankodida, Anjatsikolo, Anbatotsilongolongo, Mahazoarivo, Masiabiby, and Mikea.
Within the protected regions it is known to inhabit, the ring-tailed lemur is sympatric (shares its range) with as many as 24 species of lemur, covering every living genus except Allocebus, Indri, and Varecia. Historically, the species used to be sympatric with the critically endangered southern black-and-white ruffed lemur (Varecia variegata editorum), which was once found at Andringitra National Park; however, no sightings of the ruffed lemur have been reported in recent years.
The ring-tailed lemur is an opportunistic omnivore primarily eating fruits and leaves, particularly those of the tamarind tree (Tamarindus indica), known natively as kily. When available, tamarind makes up as much as 50% of the diet, especially during the dry, winter season. The ring-tailed lemur eats from as many as three dozen different plant species, and its diet includes flowers, herbs, bark and sap. It has been observed eating decayed wood, earth, spider webs, insect cocoons, arthropods (spiders, caterpillars, cicadas and grasshoppers) and small vertebrates (birds and chameleons). During the dry season it becomes increasingly opportunistic.
Troops are classified as multi-male groups, with a matriline as the core group. As with most lemurs, females socially dominate males in all circumstances, including feeding priority. Dominance is enforced by lunging, chasing, cuffing, grabbing and biting. Young females do not always inherit their mother's rank and young males leave the troop between three and five years of age. Both sexes have separate dominance hierarchies; females have a distinct hierarchy while male rank is correlated with age. Each troop has one to three central, high-ranking adult males who interact with females more than other group males and lead the troop procession with high-ranking females. Recently transferred males, old males or young adult males that have not yet left their natal group are often lower ranking. Staying at the periphery of the group they tend to be marginalized from group activity.
A group of three ring-tailed lemurs rest in the sun, with two sitting upright, facing the sun, with their arms to their sides.
The ring-tailed lemur will sit facing the sun to warm itself in the mornings.
For males, social structure changes can be seasonal. During the six-month period between December and May a few males migrate between groups. Established males transfer on average every 3.5 years, although young males may transfer approximately every 1.4 years. Group fission occurs when groups get too large and resources become scarce.
In the mornings the ring-tailed lemur sunbathes to warm itself. It faces the sun sitting in what is frequently described as a "sun-worshipping" posture or lotus position. However, it sits with its legs extended outward, not cross-legged, and will often support itself on nearby branches. Sunning is often a group activity, particularly during the cold mornings. At night, troops will split into sleeping parties huddling closely together to keep warm.
Despite being quadrupedal the ring-tailed lemur can rear up and balance on its hind legs, usually for aggressive displays. When threatened the ring-tailed lemur may jump in the air and strike out with its short nails and sharp upper canine teeth in a behaviour termed jump fighting. This is extremely rare outside of the breeding season when tensions are high and competition for mates is intense. Other aggressive behaviours include a threat-stare, used to intimidate or start a fight, and a submissive gesture known as pulled-back lips.
Border disputes with rival troops occur occasionally and it is the dominant female's responsibility to defend the troop's home range. Agonistic encounters include staring, lunging approaches and occasional physical aggression, and conclude with troop members retreating toward the center of the home range.
14-10-2015 VALENCIA BIOPARC - GREY CROWNED CRANE (Balearica regulorum)
The grey crowned crane (Balearica regulorum), also known as the African crowned crane, golden crested crane, golden crowned crane, East African crane, East African crowned crane, African crane, Eastern crowned crane, Kavirondo crane, South African crane, and crested crane, is a bird in the crane family, Gruidae. It is found in nearly all of Africa, especially in eastern and southern Africa, and it is the national bird of Uganda.
The grey crowned crane is closely related to the black crowned crane, and the two species have sometimes been treated as the same species. The two are separable on the basis of genetic evidence, calls, plumage, and bare parts, and all authorities treat them as different species today.
There are two subspecies. The East African B. r. gibbericeps (crested crane) occurs in the east of the Democratic Republic of the Congo and in Uganda, of which it is the national bird represented in its national flag, and Kenya to eastern South Africa. It has a larger area of bare red facial skin above the white patch than the smaller nominate species, B. r. regulorum (South African crowned crane), which breeds from Angola south to South Africa.
The grey crowned crane is approximately 1 m (3 ft 3 in) tall, weighs 3.5 kg (7.7 lb), and has a wingspan of 2 m (6 ft 7 in). Its body plumage is mainly grey. The wings are predominantly white but contain feathers with a range of colours, with a distinctive black patch at the very top. The head has a crown of stiff golden feathers. The sides of the face are white, and there is a bright red inflatable throat pouch. The bill is relatively short and grey, and the legs are black. They have long legs for wading through the grasses. The feet are large, yet slender, adapted for balance rather than defence or grasping. The sexes are similar, although males tend to be slightly larger. Younger cranes are greyer than adults, with a feathered buff face.
This species and the black crowned crane are the only cranes that can roost in trees, because of a long hind toe that can grasp branches. This trait is assumed to be an ancestral trait among the cranes, which has been lost in the other subfamily. Crowned cranes also lack a coiled trachea and have loose plumage compared to the other cranes.
The grey crowned crane occurs in dry savannah in Sub-Saharan Africa, although it nests in somewhat wetter habitats. They can also be found in marshes, cultivated lands and grassy flatlands near rivers and lakes in Uganda and Kenya and as far south as South Africa. This animal does not have set migration patterns, and birds nearer the tropics are typically sedentary. Birds in more arid areas, particularly Namibia, make localised seasonal movements during drier periods.
The grey crowned crane has a breeding display involving dancing, bowing, and jumping. It has a booming call which involves inflation of the red gular sac. It also makes a honking sound quite different from the trumpeting of other crane species. Both sexes dance, and immature birds join the adults. Dancing is an integral part of courtship, but also may be done at any time of the year.
Flocks of 30–150 birds are not uncommon.
These cranes are omnivores, eating plants, seeds, grain, insects, frogs, worms, snakes, small fish and the eggs of aquatic animals. Stamping their feet as they walk, they flush out insects which are quickly caught and eaten. The birds also associate with grazing herbivores, benefiting from the ability to grab prey items disturbed by antelopes and gazelles. They spend their entire day looking for food. At night, the crowned crane spends its time in the trees sleeping and resting.
Grey crowned cranes time their breeding season around the rains, although the effect varies geographically. In East Africa the species breeds year-round, but most frequently during the drier periods, whereas in Southern Africa the breeding season is timed to coincide with the rains. During the breeding season, pairs of cranes construct a large nest; a platform of grass and other plants in tall wetland vegetation.
The grey crowned crane lays a clutch of 2-5 glossy, dirty-white eggs, which are incubated by both sexes for 28–31 days. Chicks are precocial, can run as soon as they hatch, and fledge in 56–100 days. Once they are fully grown and independent, chicks of different sexes will separate from their parents to start their own family. Grey crowned cranes have been seen to congregate in large numbers in a ceremony akin to a wedding when two chicks are being married off. The new couple dance for a while before flying off together to start a new family.
14-10-2015 VALENCIA BIOPARC - GREATER FLAMINGO (Phoenicopterus roseus)
The greater flamingo (Phoenicopterus roseus) is the most widespread and largest species of the flamingo family. Common in the Old World, they are found in Northern (coastal) and Sub-Saharan Africa, the Indian Subcontinent (south of the Himalayas), the Middle East, the Levant, the Persian Gulf, the Gulf of Aden, the Red Sea, and the Mediterranean countries of Southern Europe.
%2011.jpg)
The greater flamingo was described by Peter Simon Pallas in 1811. It was previously thought to be the same species as the American flamingo (Phoenicopterus ruber), but because of coloring differences of its head, neck, body, and bill, the two flamingos are now most commonly considered separate species. The greater flamingo has no subspecies and is therefore monotypic.
14-10-2015 VALENCIA BIOPARC - GRANT'S GAZELLE (Nanger granti)
Grant's gazelle (Nanger granti) is a relatively large species of gazelle antelope, distributed from northern Tanzania to South Sudan and Ethiopia, and from the Kenyan coast to Lake Victoria. Its Swahili name is swala granti. It was named for a 19th-century British explorer, James Grant.
Grant's gazelle is genetically related to Soemmerring's gazelle (N. soemmerringii) and Thomson's gazelle (Eudorcas thomsonii) with Soemmering's gazelle being the closer relative. Grant's gazelle shows high genetic variation among its populations, although there is no geographic isolation. The differentiation of the species may have evolved during repeated expansion and contraction of arid habitats during the late Pleistocene era in which populations were possibly isolated. Grant's gazelle was formerly considered a member of the genus Gazella within the subgenus Nanger before Nanger was elevated to genus status. In 2021, the American Society of Mammalogists granted full species status to Bright's gazelle (Nanger notatus) and the Peter's gazelle (Nanger petersii).
Grant's gazelle are found in several countries in East Africa, including Ethiopia, Kenya, South Sudan and Tanzania, where they live in small to midsized herds, separated into females with juveniles and bachelor groups; during the mating season, when males become territorial and protective over a harem of females to breed with, bachelor herds briefly married disperse before tensions die-down again. Confrontations between hormonal males rarely end in violence or death, with the ‘loser’ simply fleeing.
Grant’s gazelle prefer living on short, grassy plains where they can graze, but can also be found browsing and foraging in more sparse, arid scrublands; they avoid areas with excessively high, untrimmed grass with compromised visibility of predators. They also occur in semiarid areas, being relatively well-adapted to drier areas, relying on more arboreal browse or shrubby, leafy material during the dry seasons to supplement their intake of water. They are sometimes seasonally migratory, but do not travel along the same routes as most of the other savanna ungulates, such as the Cape buffalo, plains zebra, Thomson’s gazelle and the white-bearded gnu, which are all far more susceptible to dehydration. Grant’s gazelle can subsist on vegetation in waterless, semiarid areas, where they face considerably less resource competition.
14-10-2015 VALENCIA BIOPARC - SOUTHERN WHITE RHINOCEROS (Ceratotherium simum simum)
The southern white rhinoceros or southern white rhino (Ceratotherium simum simum) is one of the two subspecies of the white rhinoceros (the other being the much rarer northern white rhinoceros). It is the most common and widespread subspecies of rhinoceros.
The southern white rhinoceros is the nominate subspecies; it was given the scientific name Ceratotherium simum simum by the English explorer William John Burchell in the 1810s. The subspecies is also known as Burchell's rhinoceros (Ceratotherium simum burchellii) after Burchell and Oswell's rhinoceros (Ceratotherium simum oswellii) after William Cotton Oswell, respectively. However, these are considered synonyms of its original scientific name.
Ceratotherium simum kiaboaba (or Rhinoceros kiaboaba), also known as straight-horned rhinoceros, was proposed as a different subspecies (or species) found near Lake Ngami and north of the Kalahari desert. However, it is now considered part of the southern white rhinoceros and ranges throughout southern Africa.
Following the phylogenetic species concept, research in 2010 suggested the southern and northern white rhinoceros may be different species, rather than subspecies, in which case the correct scientific name for the northern subspecies is Ceratotherium cottoni and the southern subspecies should be known as simply Ceratotherium simum. Distinct morphological and genetic differences suggest the two proposed species have been separated for at least a million years.
14-10-2015 VALENCIA BIOPARC - SOUTHERN LION (FEMALE) (Panthera leo ssp. melanochaita)
Panthera leo melanochaita is a lion subspecies in Southern and East Africa. In this part of Africa, lion populations are regionally extinct in Lesotho, Djibouti and Eritrea, and are threatened by loss of habitat and prey base, killing by local people in retaliation for loss of livestock, and in several countries also by trophy hunting. Since the turn of the 21st century, lion populations in intensively managed protected areas in Botswana, Namibia, South Africa and Zimbabwe have increased, but declined in East African range countries. In 2005, a Lion Conservation Strategy was developed for East and Southern Africa.
Results of a phylogeographic study indicate that lion populations in southern and eastern Africa are forming a major clade distinct from lion populations in West Africa, Central Africa and Asia.[5] In 2017, the Cat Classification Task Force of the IUCN Cat Specialist Group subsumed lion populations according to the major clades into two subspecies, namely P. l. leo and P. l. melanochaita.[1] Within P. l. melanochaita three subclades are clearly distinguishable. One from northeastern Africa, another one from southwestern Africa and a third one from southeastern Africa.
The type specimen for P. l. melanochaita was a black-maned lion from the Cape of Good Hope, known as the Cape lion. Phylogeographic analysis of lion samples from Gabon and the Republic of the Congo indicate their close genetic relation to P. l. melanochaita samples from Namibia and Botswana. It has been referred to as the Southern lion, Southern African lion, East-Southern African lion and the "southern subspecies".
18-11-2015 VILLALONGA RESERVOIR, VALENCIA - MALLARD (FEMALE) (Anas platyrhynchos)
The Mallard is the ancestor of nearly all domestic duck breeds (everything except the Muscovy Duck). Domestic ducks can be common in city ponds and can be confusing to identify—they may lack the white neck ring, show white on the chest, be all dark, or show oddly shaped crests on the head.
The widespread Mallard has given rise to a number of populations around the world that have changed enough that they are considered separate species. The Mexican Duck of central Mexico and the extreme southwestern United States and the Hawaiian Duck both are closely related to the Mallard, and in both forms the male is dull like the female. Both have been given full species status.
Mallard pairs are generally monogamous, but paired males pursue females other than their mates. So-called “extra-pair copulations” are common among birds and in many species are consensual, but male Mallards often force these copulations, with several males chasing a single female and then mating with her.
Mallard pairs form long before the spring breeding season. Pairing takes place in the fall, but courtship can be seen all winter. Only the female incubates the eggs and takes care of the ducklings.
19-11-2015 CANAL LES FONTS OLIVA, VALENCIA - MALLARD (MALE) (Anas platyrhynchos)
The mallard (Anas platyrhynchos) is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa. Mallards live in wetlands, eat water plants and small animals, and prefer to congregate in flocks of varying sizes. Unlike many waterfowl, mallards are considered an invasive species in some regions. It is a very adaptable species, being able to live and even thrive in urban areas. This species is the main ancestor of most breeds of domestic duck, and its naturally evolved wild gene pool has been genetically polluted by the domestic and feral mallard populations.
The magnificent mallard is one of the most recognizable bird species around the world. When flying, the bird displays a purplish-blue speculum, which is outlined in white. Males of this species are particularly colorful. Breeding males have a yellow beak, dark brown chest, black and white tail as well as bright green head and neck. They exhibit a white ring at the base of their neck. In addition, the sides of breeding males and most of their wings are gray. On the other hand, the plumage of female mallards and non-breeding males is less vivid and colorful. The overall plumage of female mallards is spotted with tan and brown patches, and the head is a lighter tan, showing dark bands near the crown and eyes. Females have orange-colored beaks, covered with dark spots. Females and non-breeding males generally look alike, though the latter have yellowish beaks.
19-11-2015 OLIVA MARJAL, VALENCIA - LITTLE EGRET (Egretta garzetta)
The Little egret (Egretta garzetta) is small elegant Heron in the family Ardeidae. As an aquatic bird, it feeds in shallow water and on land, consuming a variety of small creatures. At one time common in Western Europe, the Little heron was hunted extensively in the 19th century to provide plumes for the decoration of hats and became locally extinct in Northwestern Europe and scarce in the south. Around 1950, conservation laws were introduced in southern Europe to protect the species and their numbers began to increase.
The plumage of the Little egret is normally entirely white, although there are dark forms with largely bluish-grey plumage. In the breeding season, the adult has two long plumes on the nape that form a crest. These plumes are about 150 mm (6 in) and are pointed and very narrow. There are similar feathers on the breast, but the barbs are more widely spread. There are also several elongated scapular feathers that have long loose barbs and may be 200 mm (8 in) long. During the winter the plumage is similar but the scapulars are shorter and more normal in appearance. The bill is long and slender and it and the lores are black. There is an area of greenish-grey bare skin at the base of the lower mandible and around the eye which has a yellow iris. The legs are black and the feet yellow. Juveniles are similar to non-breeding adults but have greenish-black legs and duller yellow feet, and may have a certain proportion of greyish or brownish feathers. The subspecies nigripes differs in having yellow skin between the bill and eye, and blackish feet. During the height of courtship, the lores turn red and the feet of the yellow-footed races turn red.
Little egrets are found in southern Europe, the Middle East, much of Africa, and southern Asia. Northern European populations are migratory and mostly travel to Africa although some remain in southern Europe, while some Asian populations migrate to the Philippines. The eastern subspecies is resident in Indonesia and New Guinea, while other populations inhabit Australia and New Zealand, but do not breed in the latter. Little egrets live in various habitats including the shores of lakes, rivers, canals, ponds, lagoons, marshes, and flooded land. These birds prefer open locations to dense cover. On the coast, they inhabit mangrove areas, swamps, mudflats, sandy beaches, estuaries, and reefs. Rice fields are an important habitat in Italy, and coastal and mangrove areas are important in Africa.
Little egrets are sociable birds and are often seen in small flocks. They are diurnal birds and feed mainly in the early morning and in the late afternoon. They use a variety of methods to procure their food; they stalk their prey in shallow water, often running with raised wings or shuffling their feet to disturb small fish, or may stand still and wait to ambush prey. Little egrets also make use of opportunities provided by cormorants disturbing fish or humans attracting fish by throwing bread into the water. On land, they walk or run while chasing their prey, feed on creatures disturbed by grazing livestock and ticks on the livestock, and even scavenge occasionally. Little egrets are silent birds in general, however, at their breeding colonies, they make various croaking and bubbling calls. When disturbed, they produce a harsh alarm call.
Little egrets are carnivorous (piscivorous) birds. Their diet includes mainly fish, but they also eat amphibians, small reptiles, mammals, and birds, as well as crustaceans, mollusks, insects, spiders, and worms.
19-11-2015 OLIVA MARJAL, VALENCIA - EUROPEAN GOLDFINCH (MALE) (Carduelis carduelis)
%20(Carduelis%20carduelis)%2010.jpg)
The European goldfinch or simply the goldfinch is a small passerine bird in the finch family that is native to Europe, North Africa, and western and central Asia.
The European goldfinch is native to Europe, North Africa, and Western and Central Asia. It is found in open, partially wooded lowlands and is a resident in the milder west of its range, but migrates from colder regions. It will also make local movements, even in the west, to escape bad weather.

30-12-2015 HOI AN, VIETNAM - EURASIAN TREE SPARROW (MALE) (Passer montanus)
The Eurasian tree sparrow (Passer montanus) is asmall passerine bird that breeds over most of temperate Eurasia and Southeast Asia, where it is known as the Tree sparrow. It has been introduced elsewhere including the United States, where it is known as the Eurasian tree sparrow or German sparrow to differentiate it from the native unrelated American tree sparrow.
The adult's crown and nape are rich chestnut, and there is a kidney-shaped black ear patch on each pure white cheek; the chin, throat, and the area between the bill and throat are black. The upperparts are light brown, streaked with black, and the brown wings have two distinct narrow white bars. The legs are pale brown, and the bill is lead-blue in summer, becoming almost black in winter. This sparrow is distinctive even within its genus in that it has no plumage differences between the sexes; the juvenile also resembles the adult, although the colors tend to be duller. Its contrasting face pattern makes this species easily identifiable in all plumages; the smaller size and brown, not grey, crown are additional differences from the male house sparrow. Adult and juvenile Eurasian tree sparrows undergo a slow complete molt in the autumn and show an increase in body mass despite a reduction in stored fat. The change in mass is due to an increase in blood volume to support active feather growth and generally higher water content in the body.
