Zoo, also called zoological garden or zoological park, place where wild animals and, in some instances, domesticated animals are exhibited in captivity.. Most long-established zoos exhibit general collections of animals, but some formed more recently specialize in particular groups�e.g., primates, big cats, tropical birds, or waterfowl. Marine invertebrates, fishes, and marine mammals often are kept in separate establishments known as aquariums.
Galliformes are an order of heavy-bodied ground-feeding birds, containing turkey, grouse, chicken, New and Old World quail, ptarmigan, partridge, pheasant, and the Cracidae. Common names are gamefowl or gamebirds, landfowl, gallinaceous birds or galliforms. "Wildfowl" or just "fowl" are also often used for Galliformes, but usually these terms also refer to waterfowl (Anseriformes), and occasionally to other commonly hunted birds. This group has about 290 species, one or more of which are found in essentially every part of the world's continents (except for the innermost deserts and perpetual ice). They are more rare on islands, and in contrast to the closely related waterfowl are essentially absent from oceanic islands� unless introduced there by humans. Several species have been domesticated during their long and extensive relationship with humans.
This order contains five families: Phasianidae (including chicken, quail, partridges, pheasants, turkeys, and grouse), Odontophoridae (New World quails), Numididae (guineafowl), Cracidae (including chachalacas and currasows), and Megapodiidae (incubator birds like mallee fowl and brush-turkeys). They are important as seed dispersers and predators in the ecosystems they inhabit, and are often reared as game birds by humans for their meat and eggs and for recreational hunting. All are skilled runners that can fly only a few hundred feet when escaping danger . Males of most species are more colorful than the females. Males often have elaborate courtship behaviors that include strutting, fluffing of tail or head feathers, and vocal sounds. They are mainly non-migratory.
