The logrunners (Orthonyx) are a clade of birds which comprises three species of passerine birds endemic to Australia and New Guinea. Some authorities consider the Australian family Cinclosomatidae to be part of the Orthonychidae. The three species use their stiffened tails to brace themselves when feeding. The chowchilla, Orthonyx spaldingii, from north-east Queensland, is much larger than either species of logrunner, and has a jet-black plumage, the throat being white in the male and orange-rufous in the female.
