The brown songlark (Cincloramphus cruralis), also Australian songlark, is a small passerine bird found throughout much of Australia. A member of the family Locustellidae, this species is notable for sexual size dimorphism, among the most pronounced in any bird. It is a moderate-sized bird of nondescript plumage; the female brownish above and paler below, the larger male a darker brown. The bird is found throughout Australia, except for parts of the far north and Tasmania. There are particularly dense populations in the southern parts of the country. It prefers open pastures and grassy scrub, and feeds on seeds and insects. The species is highly nomadic. Local numbers fluctuate depending on rainfall and the bird will often flee from drought-affected areas. (Source: Wikipedia.org, CC BY-SA)
