Pale-headed Rosella

Platycercus adscitus

Medium111 gWoodland

The pale-headed rosella is 33 cm (13 in) long, which includes the 15 cm length of its tail. Its underparts are pale blue, and upper breast and head are pale cream-yellow, the tail which is blue-black and green and the vent which is blood red. The feathers of the nape, scapulars and back are black edged with bright yellow, giving rise to a scalloped appearance. In these margins of the northern race, the yellow is paler with a pale blue tinge. The cheeks are wholly white in the southern subspecies, and partly flushed with blue in the lowerparts in the northern subspecies.
