Buff-breasted Buttonquail
The Buff-breasted Buttonquail (Turnix olivii) is the largest and possibly the rarest of the buttonquail. This species is endemic to extreme northeastern Australia, in northern Queensland from near Coen to Mareeba west of Cairns.
Description
The Buff-breasted Buttonquail measures from 18–23 centimetres (7.1–9.1 in) and usually weighs over 110 grams (3.9 oz). Both the tail and wings are short. The back is chestnut. The sides of the head are marked with chestnut on an otherwise plain gray head; while the breast is warm buff-colored. The Painted Buttonquail and the Brown Quail both coexist with this species. The Buff-breasted is larger (and longer-legged) than either and is quite different different from the all-dark quail. The Painted species is almost totally mottled, with bold white spotting on the breast and no warm buff coloration. The most similar species to the Buff-breasted is the Chestnut-backed Buttonquail, which does not overlap in the wild.
