Brehm's tiger parrot (Psittacella brehmii), also known as Brehm's ground parrot, is a small mainly green parrot found in the highlands of New Guinea, from 1,500-2,600m (extremes 1,100-3,800m). The species is named after Alfred Brehm (1829–1884), a German traveller and collector.
Brehm's tiger parrot is the largest species in the genus Psittacella and is about 24 cm in length and weighs between 94 to 120 g. It is mainly green with a dull olive-brown head, transverse yellow and black bars on the back and rump, and red undertail coverts. Its irises are red, and its beak is blueish-grey fading to white at the tip. Its legs are grey. The male has a yellow stripe on the sides of its neck and a green breast without barring. Females lack the yellow stripe on the neck and have a yellow and black striped breast. Juveniles resemble females, but have yellowish-brown irises and a more faded green and pale-yellow barring on the breast.
