It breeds in the holes of the highest white gum-trees, often in the most dense and retired part of the forest. The eggs are generally two in number, of a pure white; their average length being one inch and three-quarters by one inch and three-eighths in breadth. The breeding-season extends over the months of October, November and December.

Up to the time of writing this account I have never seen specimens from any other part of Australia than the colony of Swan River, over the whole of which it seems to be equally distributed.

The entire plumage is blackish brown, glossed with green, especially on the forehead; all the feathers narrowly tipped with dull white; ear-coverts creamy white; all but the two central tail-feathers crossed by a broad band, equal to half their length, of cream-white; the external web of the outer primary and the margin of the external web of the other banded feathers blackish brown; the shafts black; irides blackish brown; bill lead-colour; in some specimens the upper mandible is blackish brown; legs and feet dull yellowish grey, tinged with olive.

The figure represents a male about three-fourths of the natural size.
