Apodiformes(redirected from Apodiform)
Also found in: Dictionary, Thesaurus, Wikipedia.
an order of birds, uniting two clearly defined suborders—the swifts and the hummingbirds. Its distinctive external feature is the wing structure: very long and narrow with a shortened shoulder bone and short secondary flight feathers, which give Apodiformes speed and maneuverability. They lay one to three white eggs. The fledglings hatch blind; the parents feed them until they are able to fly. There are about 400 species; they are found in temperate and, particularly, in tropical zones.
