Grey Grasswrens Amytornis barbatus barbatus
were studied in an 11 hectare area of tall, dense Lignum
in the Caryapundy Swamp of south-western Queensland between 1984 and 1996.
One hundred and ninty-three individuals were captured and banded and 35 (18.1 %) individuals were retrapped a
total of 46 times. A pair of grasswrens with two recently fledged chicks were observed and later captured in an
isolated stand of Lignum approximately 0.5 hectares in area. Most grasswrens were captured during periods of
drought, suggesting that the species congregates in prime habitat refuge areas during periods of climatic extreme.
The greatest threat to the Grey Grasswren appeared to be habitat destruction by introduced feral and domestic
herbivores. Preservation of tall dense Lignum that offers food and shelter to support a high density of Grey
Grasswrens during drought is crucial to the conservation of the species.
