Amytornis ballarae
The Kalkadoon Grasswren, *Amytornis ballarae*, is a small, highly cryptic passerine endemic to the arid rocky ranges of western Queensland, Australia. Measuring approximately 16-18 cm in length and weighing 15-20 grams, it is characterized by its heavily streaked, brownish upperparts and whitish underparts. Distinctive field marks include bold white streaking on a dark head and back, contrasting with deep rufous flanks and a plain white belly, often accentuated by a long, cocked tail. Taxonom...
This species exclusively inhabits arid and semi-arid rocky hills and ranges, specifically areas dominated by dense spinifex (Triodia spp.) growing on stony slopes and in gullies. It typically occurs at low elevations, generally below 500 meters.

Kalkadoon Grasswrens are highly secretive and predominantly diurnal, with peak activity during the cooler hours of early morning and late afternoon, spending most of their time concealed within the dense spinifex. They forage primarily on the ground, gleaning insects and seeds from within and ben...
