Philippine Cuckoo-dove
The Philippine cuckoo-dove (''Macropygia tenuirostris'') is a species of bird in the family Columbidae. It is found in the Philippines and Taiwan and is rated as a species of least concern on the International Union for Conservation of Nature Red List of Endangered Species. Taxonomy and systematics The Philippine cuckoo-dove was first described by the French zoologist Charles Lucien Jules Laurent Bonaparte in 1854. Formerly, some authorities classified it as a subspecies of either the ruddy cuckoo-dove or the brown cuckoo-dove. It was split from the slender-billed cuckoo-dove in 2016 and has four sub-species recognized: * ''M. t. phaea'' McGregor, 1904 - Lanyu Island, Batan Island, and Calayan Island * ''M. t. tenuirostris'' Bonaparte, 1854 - Philippines * ''M. t. borneensis'' Robinson & Kloss, 1921 - Borneo. Provisionally moved from ruddy cuckoo-dove to ''Macropygia tenuirostris'' by the IOU. * ''M. t. septentrionalis'' Hachisuka, 1930 - Batan, Itbayat and Sabtan Islands ...

Charles Lucien Bonaparte
Charles Lucien Jules Laurent Bonaparte, 2nd Prince of Canino and Musignano (24 May 1803 – 29 July 1857), was a French naturalist and ornithologist. Lucien and his wife had twelve children, including Cardinal Lucien Bonaparte. Life and career Bonaparte was the son of Lucien Bonaparte and Alexandrine de Bleschamp. Lucien was a younger brother of Napoleon I, making Charles the emperor’s nephew. Born in Paris, he was raised in Italy. On 29 June 1822, he married his cousin, Zénaïde, in Brussels. Soon after the marriage, the couple left for Philadelphia in the United States to live with Zénaïde's father, Joseph Bonaparte (who was also the paternal uncle of Charles). Before leaving Italy, Charles had already discovered a warbler new to science, the moustached warbler, and on the voyage he collected specimens of a new storm-petrel. On arrival in the United States, he presented a paper on this new bird, which was later named after Alexander Wilson. Bonaparte then set about ...

Macropygia
''Macropygia'' is a genus of bird in the pigeon and dove family Columbidae. The genus is one of three genera known as cuckoo-doves. They are long tailed, range between 27 and 45 cm in length and have brown plumage. The genus ranges from India and China through Indonesia and the Philippines to Vanuatu and Australia. The genus ''Macropygia'' was introduced in 1837 by the English naturalist William John Swainson. The name combines the Ancient Greek ''makros'' meaning "long" or "deep" and "-pugios" meaning "-rumped"). The type species is the brown cuckoo-dove (''Macropygia phasianella''). The genus contains the following 15 species: * Barred cuckoo-dove (''Macropygia unchall'') * Amboyna cuckoo-dove (''Macropygia amboinensis'') * Sultan's cuckoo-dove (''Macropygia doreya'') * Ruddy cuckoo-dove (''Macropygia emiliana'') * Enggano cuckoo-dove (''Macropygia cinnamomea'') * Barusan cuckoo-dove (''Macropygia modiglianii'') * Timor cuckoo-dove (''Macropygia magna'') * Tanimbar cuckoo ...

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

IUCN Red List of Endangered Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide scie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tail Coverts
A covert feather or tectrix on a bird is one of a set of feathers, called coverts (or ''tectrices''), which, as the name implies, cover other feathers. The coverts help to smooth airflow over the wings and tail. Ear coverts The ear coverts are small feathers behind the bird's eye which cover the ear opening (the ear of a bird has no external features) Tail coverts The uppertail and undertail coverts cover the base of the tail feathers above and below. Sometimes these coverts are more specialised. The "tail" of a peacock is made of very elongated uppertail coverts. Wing coverts The upperwing coverts fall into two groups: those on the inner wing, which overlay the secondary flight feathers, known as the secondary coverts, and those on the outerwing, which overlay the primary flight feathers, the primary coverts. Within each group, the feathers form a number of rows. The feathers of the outermost, largest, row are termed greater (primary-/secondary-) coverts; those in the next row ...

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 ...

Iris (anatomy)
In humans and most mammals and birds, the iris (plural: ''irides'' or ''irises'') is a thin, annular structure in the eye, responsible for controlling the diameter and size of the pupil, and thus the amount of light reaching the retina. Eye color is defined by the iris. In optical terms, the pupil is the eye's aperture, while the iris is the diaphragm. Structure The iris consists of two layers: the front pigmented fibrovascular layer known as a stroma and, beneath the stroma, pigmented epithelial cells. The stroma is connected to a sphincter muscle (sphincter pupillae), which contracts the pupil in a circular motion, and a set of dilator muscles ( dilator pupillae), which pull the iris radially to enlarge the pupil, pulling it in folds. The sphincter pupillae is the opposing muscle of the dilator pupillae. The pupil's diameter, and thus the inner border of the iris, changes size when constricting or dilating. The outer border of the iris does not change size. The constricti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nape
The nape is the back of the neck. In technical anatomical/medical terminology, the nape is also called the nucha (from the Medieval Latin rendering of the Arabic , "spinal marrow"). The corresponding adjective is ''nuchal'', as in the term ''nuchal rigidity'' for neck stiffness. In many mammals the nape bears a loose, non-sensitive area of skin, known as the scruff, by which a mother carries her young by her teeth, temporarily immobilizing it during transport. In the mating of cats the male will grip the female's scruff with his teeth to help immobilize her during the act, a form of pinch-induced behavioral inhibition Pinch-induced behavioural inhibition (PIBI), also called dorsal immobility, transport immobility or clipnosis, is a partially inert state which results from a gentle squeeze of the skin behind the neck. It is mostly observed among cats and allows .... Cultural connotations In traditional Japanese culture, the was one of the few areas of the body (other than ...

Crown (anatomy)
The crown is the top portion of the head behind the vertex. The anatomy of the crown varies between different organisms. The human crown is made of three layers of the scalp above the skull. The crown also covers a range of bone sutures, and contains blood vessels and branches of the trigeminal nerve. The structure of the human crown provides a protective cavity for the brain and optimizes the crown's ability to ensure the neocortex is safe. Different parts of the neocortex, such as the frontal lobe and the parietal lobe, are protected by the meninges and bone structures. Other organisms, such as whales, have their blowholes on their crown, causing a flattened head shape. Some bird species have a crest located on their crown, used for communication and courtship. Macroevolution of the human crown has led to different structures between modern and archaic human species, such as significant changes to the cranial vault. The human crown is prone to different injuries and disord ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
