Observations of the Striated Grasswren Amytornis striatus rowleyi at Opalton, central western Queensland

Abstract

Ninety-six records of the Striated Grasswren Amytornis striatus rowleyi (Rusty Grasswren A. rowleyi) were obtained during 14 visits to Opalton in central western Queensland between May 2009 and October 2012. Most records (35) were of groups with a minimum of two individuals (range 1–9+). Three calls are described: contact call, song and alarm. They were uttered throughout the day from first light to sunset. In 12 records, Striated Grasswrens were seen to fly, usually 30–40 cm above the ground over a median distance of 15 m (range 8–35 m). Groups of Striated Grasswrens were associated with Rufous-crowned Emu-wrens Stipiturus ruficeps in 15 records. Inquisitive behaviour is described, and other behaviours are compared with co-occurring Rufous-crowned Emu-wrens (34 groups) and Spinifexbirds Eremiornis carteri (19 individuals).
