All birds fly except for members of the Ratite family (such as the ostrich, emu, and kiwi), members of the Anseriforme family (Falkland Steamer Duck and the Auckland Teal), Podicipediformes such as the Titica Grebe, and many members of the Gruiforme family which includes cranes and rails. Penguins do not fly, along with the Flightless Comorant and the Kakapo parrot.
