Thrush, of the Colonists. — - 
Tuts species is about the size of the Colluricincla harmonica, for which at a first glance it might be mistaken, 
but from which on comparison it will be found to differ in the following particulars :—the whole of the 
upper surface is pure grey instead of brown; the abdomen and under tail-coverts are deep buff instead of 
greyish white; and the lores are much more distinctly marked with white. It is a native of Western 
Australia, where it is to be found in all thickly wooded places, feeding as much on the ground as among 
the trees and scrubs. In its actions, the positions it assumes, and in its general manners, it very closely 
resembles the Common Thrush of Europe. Its voice is a very loud, full and rich swelling note with a few 
connecting sounds, the whole much resembling, but not equalling in melody, the call-note of the European 
Thrush. 
It breeds in the latter part of September and the begining of October, and the nest, which is generally 
placed in the hollow part of a high tree, is formed of dried strips of gum-tree bark very closely packed and 
deep, and is sometimes lined with soft grasses. The eggs, which are two or three in number, are of a 
beautiful bluish or pearly white, with large blotches of reddish olive-brown and dark grey, the latter 
appearing as if beneath the surface of the shell; the medium length of the eggs is one inch and one line by 
ten lines in breadth. 
Mr. Gilbert mentions that upon two occasions he found the eggs of this bird in old nests of Pomatorhinus 
superciliosus. | 
The stomach is muscular, and the food consists of insects, principally of the coleopterous order, and 
seeds. 
Lores greyish white ; crown of the head and all the upper surface deep grey, slightly tinged with olive ; 
primaries and tail dark brown, margined with brownish grey; throat and under surface darkish grey, 
passing into buff on the vent and under tail-coverts; all the feathers of the under surface have a narrow 
dark line down the centre ; thighs grey ; trides dark reddish brown; bill blackish brown ; feet dark greenish 
leaden grey. 
The figures represent a male and a female of the natural size.
