Dusky Grasswren

The dusky grasswren is superficially similar in appearance to a number of the other grasswrens in the genus Amytornis, but is the only member of this genus to exclusively inhabit rocky ranges across Central Australia. It has a predominantly brown base colour to its plumage with fine pale streaking over the head breast and mantle. The brown of the plumage is a richer chestnut on the back and pale to almost buff on the belly and vent. Voice: This species most often reveals itself initially with a sharp, metallic tutting in alarm or a drawn-out seeeep contact call. The vocal repertoire of the dusky grasswren is varied and includes trills, high-pitched whistles, rapid twittering, and high-speed warbling. Much of the richness in the calls is difficult for humans to detect due to the extreme speed with which they are performed.
