Flight featherFlight feathers (Pennae volatus) are the long, stiff, asymmetrically shaped, but symmetrically paired pennaceous feathers on the wings or tail of a bird; those on the wings are called remiges ('rɛmᵻdʒiːz), singular remex ('riːmɛks), while those on the tail are called rectrices (rɛk'traɪsiːs), singular rectrix ('rɛktrɪks). The primary function of the flight feathers is to aid in the generation of both thrust and lift, thereby enabling flight.
FowlFowl are birds belonging to one of two biological orders, namely the gamefowl or landfowl (Galliformes) and the waterfowl (Anseriformes). Anatomical and molecular similarities suggest these two groups are close evolutionary relatives; together, they form the fowl clade which is scientifically known as Galloanserae (initially termed Galloanseri) (Latin gallus ("rooster") + ānser ("goose")). This clade is also supported by morphological and DNA sequence data as well as retrotransposon presence/absence data.
ColumbidaeColumbidae (kəˈlʌmbᵻdiː) is a bird family consisting of doves and pigeons. It is the only family in the order Columbiformes. These are stout-bodied birds with short necks and short slender bills that in some species feature fleshy ceres. They primarily feed on seeds, fruits, and plants. The family occurs worldwide, but the greatest variety is in the Indomalayan and Australasian realms. The family contains 344 species divided into 50 genera. Thirteen of the species are extinct.
ChickenThe chicken (Gallus domesticus) is a domesticated species that arose from the red junglefowl, originally from India. They have also partially hybridized with other wild species of junglefowl (the grey junglefowl, Ceylon junglefowl, and green junglefowl). Rooster and cock are terms for adult male birds, and a younger male may be called a cockerel. A male that has been castrated is a capon. An adult female bird is called a hen, and a sexually immature female is called a pullet.
Common pheasantThe common pheasant (Phasianus colchicus) 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.
AnseriformesAnseriformes is an order of birds also known as waterfowl that comprises about 180 living species of birds in three families: Anhimidae (three species of screamers), Anseranatidae (the magpie goose), and Anatidae, the largest family, which includes over 170 species of waterfowl, among them the ducks, geese, and swans. Most modern species in the order are highly adapted for an aquatic existence at the water surface. With the exception of screamers, males have penises, a trait that has been lost in the Neoaves.
Turkey (bird)The turkey is a large bird in the genus Meleagris, native to North America. There are two extant turkey species: the wild turkey (Meleagris gallopavo) of eastern and central North America and the ocellated turkey (Meleagris ocellata) of the Yucatán Peninsula in Mexico. Males of both turkey species have a distinctive fleshy wattle, called a snood, that hangs from the top of the beak. They are among the largest birds in their ranges. As with many large ground-feeding birds (order Galliformes), the male is bigger and much more colorful than the female.
MegapodeThe megapodes, also known as incubator birds or mound-builders, are stocky, medium-large, chicken-like birds with small heads and large feet in the family Megapodiidae. Their name literally means "large foot" and is a reference to the heavy legs and feet typical of these terrestrial birds. All are browsers, and all but the malleefowl occupy wooded habitats. Most are brown or black in color. Megapodes are superprecocial, hatching from their eggs in the most mature condition of any bird.
CracidaeThe chachalacas, guans and curassows are birds in the family Cracidae. These are species of tropical and subtropical Central and South America. The range of one species, the plain chachalaca, just reaches southernmost parts of Texas in the United States. Two species, the Trinidad piping guan and the rufous-vented chachalaca occur on the islands of Trinidad and Tobago respectively. The family Cracidae was introduced (as Craxia) by the French polymath Constantine Samuel Rafinesque in 1815.
PalaeognathaePalaeognathae (ˌpæliˈɒgnəθi; ) is a infraclass of birds, called paleognaths or palaeognaths, within the class Aves of the clade Archosauria. It is one of the two extant infraclasses of birds, the other being Neognathae, both of which form Neornithes. Palaeognathae contains five extant branches of flightless lineages (plus two extinct clades), termed ratites, and one flying lineage, the Neotropic tinamous.
