The dusky grasswren (Amytornis purnelli) is a species of small passerine bird in the family Maluridae. The species is endemic to Australia, in which it is limited to inland areas of the Northern Territory, Western Australia and South Australia. The dusky grasswren inhabits rocky ranges and outcrops, often preferring tumbled talus or scree, and with areas of thick, long-unburnt spinifex grasses in the genus Triodia. In the wild it has been observed feeding on a range of small arthropods and other invertebrates as well as seeds. The vocal repertoire of the dusky grasswren is varied and includes trills, high-pitched whistles, rapid twittering, and high-speed warbling. This dusky grasswren was photographed in Ormiston Pound in the Northern Territory.Photograph credit: JJ Harrison
