either of the two species of the Australian genus Psophodes, belonging to the songbird family Muscicapidae. They are named for the voice of the eastern whipbird (P. olivaceus): the male gives a long whistle and a loud crack, and the female answers instantly with “choo” sounds. This species is 25 centimetres (10 inches) long, with broad, graduated tail, and is dark green, with white cheeks. The other, and similar, species is rare.
