Radio-tracking Grey Grasswrens Amytornis barbatus barbatus in north-western New South Wales: a pilot study


A pilot study to radio-track the movements of Grey Grasswrens Amytornis barbatus barbatus in north-western New South Wales was conducted during September, 2017. Four birds were tracked for 5–7 days using small radio-transmitters attached to the interscapular area. Minimum foraging areas varied from approximately 18 to 53 ha and encompassed a variety of plant associations dominated by Lignum Muehlenbeckia florulenta. The longest daily movement recorded was approximately 1.6 km. We also established that these birds returned to roost at night in a central area of thick Lignum. This study showed that it is possible to track Grey Grasswrens through dense thickets of Lignum and to identify their minimum foraging areas.
