Dryocopus Javensis
The white-bellied woodpecker or great black woodpecker (''Dryocopus javensis'') is found in evergreen forests of tropical Asia, including the Indian subcontinent and Southeast Asia. It has 14 subspecies, part of a complex including the Andaman woodpecker ('' Dryocopus hodgei'') (earlier treated as a subspecies). Many of its island forms are endangered, and some are extinct. Populations differ in the distribution and extent of white. They are among the largest of the Asiatic woodpeckers and nest in large dead trees, often beside rivers. Their drums and calls are louder than those of the smaller woodpeckers. Description This species is one of the largest living species of woodpecker. Adults range in size from and are behind only to the great slaty woodpecker and black woodpecker in size among Asian woodpecker species. The species is considered closely related to the more northern black woodpecker and the North American pileated woodpecker and is similar in size to these species. ...

Thomas Horsfield
Thomas Horsfield (May 12, 1773 – July 24, 1859) was an American physician and natural history, naturalist who worked extensively in Indonesia, describing numerous species of plants and animals from the region. He was later a curator of the East India Company Museum in London. Early life Horsfield was born in Bethlehem, Pennsylvania, and studied medicine at the University of Pennsylvania. He was the grandson of Timothy Horsfield, Sr. (1708-1773), who was born in Liverpool and emigrated to New York in 1725. In New York, his brother Isaac and he ran a butcher shop. The Horsfield family converted from the Church of England to Moravianism, a Protestant denomination with a strong emphasis on education. In 1748, Horsfield, Sr. applied for permission to reside in Bethlehem, Pennsylvania. He, however, moved only his family to Bethlehem and joined them the next year. When Northampton County was created in 1752, he was made a justice of peace by Governor Hamilton. In 1763 he was commissio ...

Beak
The beak, bill, or rostrum is an external anatomical structure found mostly in birds, but also in turtles, non-avian dinosaurs and a few mammals. A beak is used for eating, preening, manipulating objects, killing prey, fighting, probing for food, courtship, and feeding young. The terms ''beak'' and ''rostrum'' are also used to refer to a similar mouth part in some ornithischians, pterosaurs, cetaceans, dicynodonts, anuran tadpoles, monotremes (i.e. echidnas and platypuses, which have a beak-like structure), sirens, pufferfish, billfishes and cephalopods. Although beaks vary significantly in size, shape, color and texture, they share a similar underlying structure. Two bony projections – the upper and lower mandibles – are covered with a thin keratinized layer of epidermis known as the rhamphotheca. In most species, two holes called ''nares'' lead to the respiratory system. Etymology Although the word "beak" was, in the past, generally restricted to the sharpened bills o ...

Birds Of Southeast Asia
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the Common ostrich, ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dryocopus
''Dryocopus'' is a genus of large powerful woodpeckers, typically 35–45 cm in length. It has representatives in North and South America, Europe, and Asia; some South American species are endangered. It was believed to be closely related to the American genus ''Campephilus'', but it is part of an entirely different lineage of woodpeckers altogether (Benz ''et al.'', 2006) Their breeding habitat is forested areas with large trees, where they nest in a large cavity in a dead tree or a dead part of a tree. They may excavate a new hole each year, creating habitat for other large cavity nesting birds. They are non-migratory permanent residents. They are mainly black in plumage with red on the crown of the head, often as a crest. Most species also have some white areas of plumage, especially on the head, and some have additional red facial markings. The male, female and juvenile plumages of each species usually differ, often in the extent of red on the crown and elsewhere on the ...

Tristram's Woodpecker
Tristram's woodpecker (''Dryocopus javensis richardsi'') (, Japanese: ) is a Korean subspecies of the white-bellied woodpecker. It was firstly identified and described by English scholar and ornithologist Henry Baker Tristram in 1879. Description Tristram's woodpecker, with its 46 cm length, is among the largest of all woodpeckers. Both the tuft and the cheek patches are crimson red; its upper parts are black, which contrast with its white underparts, wing tips and a white rump. It has four toes, of which two are directed backwards. Its tail feathers are firm. Its native name was derived from its strange call, which sounds like "kullak!" Habitat and ecology This woodpecker inhabits dense mountain forests above 1,000 m, as well as urban areas. It is commonly found in areas with chestnuts, oaks, poplars, and elms. It prefers dead trees, where it nests in the hollow trunk and searches the bark for insects. The breeding period is from April to May, where the female lays three ...

Tarsus (skeleton)
In the human body, the tarsus is a cluster of seven articulating bones in each foot situated between the lower end of the tibia and the fibula of the lower leg and the metatarsus. It is made up of the midfoot (Cuboid bone, cuboid, medial, intermediate, and lateral cuneiform bone, cuneiform, and navicular) and hindfoot (Talus bone, talus and calcaneus). The tarsus articulates with the bones of the metatarsus, which in turn articulate with the proximal phalanges of the toes. The joint between the tibia and fibula above and the tarsus below is referred to as the ankle, ankle joint proper. In humans the largest bone in the tarsus is the calcaneus, which is the weight-bearing bone within the heel of the foot. Human anatomy Bones The talus bone or ankle bone is connected superiorly to the two bones of the lower leg, the tibia and fibula, to form the ankle, ankle joint or talocrural joint; inferiorly, at the subtalar joint, to the calcaneus or heel bone. Together, the talus and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tail
The tail is the section at the rear end of certain kinds of animals’ bodies; in general, the term refers to a distinct, flexible appendage to the torso. It is the part of the body that corresponds roughly to the sacrum and coccyx in mammals, reptiles, and birds. While tails are primarily a feature of vertebrates, some invertebrates including scorpions and springtails, as well as snails and slugs, have tail-like appendages that are sometimes referred to as tails. Tailed objects are sometimes referred to as "caudate" and the part of the body associated with or proximal to the tail are given the adjective "caudal". Function Animal tails are used in a variety of ways. They provide a source of locomotion for fish and some other forms of marine life. Many land animals use their tails to brush away flies and other biting insects. Most canines use their tails to comunicate mood and intention . Some species, including cats and kangaroos, use their tails for balance; and some, such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
