Mrs. Anderson told me that it lays four eggs in the hollow part of a tree, but beyond this I was unable to ascertain anything respecting its nidification.
Its voice is a hoarse, quacking, inharmonious noise, sometimes resembling the barking of a dog.
It would appear from the numerous specimens I have examined that the sexes scarcely differ from each other in colour; the young, on the contrary, have but little of the rich yellow and red markings of the breast, that part being olive-brown like the back.
The general colour of the upper surface brown; head and back of the neck tinged with grey, the feathers of these parts as well as of the back margined with a deeper tint; rump, belly, and under tail-coverts deep red; cheeks, throat, and chest yellow, the former tinged with red; shoulders on their inner surface yellow tinged with rufous olive; tail-feathers banded at the base with orange-yellow and brown; the inner webs of the quill-feathers at the base and beneath, with dusky red and brown; irides very dark brown; bill brown; nostrils, bare skin round the eye, and feet dark olive-brown.
Our Plate represents an old and a nearly adult bird, exhibiting traces of the immature plumage on the chest, of the natural size.
