Songlark

songlark, either of the two species of the Australian genus Cinclorhamphus, of the songbird family Sylviidae. Both are drab and vaguely larklike; males of both species are much larger than females. The rufous songlark (C. mathewsi), 20 cm (8 inches) long, lives in open forests and has a lively song; the 30-cm (12-inch) brown, or black-breasted, songlark (C. cruralis) lives in open country, utters creaky chuckling notes, and has a flight song, as larks do.
