Ir would seem that the whole extent of the southern coast of Australia is inhabited by the present species, 
for on comparing adult males from New South Wales, South Australia and Swan River, I find that they 
do not differ in any respect; the apical half of the tail is blackish brown in all, and the colouring of the 
under surface of the richest yellow. It is rather abundantly dispersed over the forests of Eucalypti and 
the belts of 4eacie, among the flowering branches of which latter tribe of trees the male displays himself 
to the greatest advantage, and shows off his rich yellow breast as if desirous of outyieing the beautiful 
blossoms with which he is surrounded. 
The stomach is very muscular, and its principal food consists of insects of various genera, which are 
sought for and captured both among the flowers and leaves as well as on the ground. 
It is generally met with in pairs, but the males are more shy than the females. It flies in short and 
sudden starts, and seldom mounts far above the tops of the trees. 
The voice of the male is a single note seven or eight times repeated, and terminating with a sharp 
higher note much resembling the smack of a whip; that of the female is very different, being a series of 
running half-notes, forming a rather plaintive tune. 
Mr. Gilbert mentions that it is sparingly dispersed throughout the Swan River colony, but is more 
abundant in the best-watered districts, such as Perth and Fremantle. | 
I did not succeed in finding the nest of this species, but was informed that it breeds in September and 
October, and lays three or four eggs, ten and a half lines long by eight lines broad, with a ground-colour 
of brownish buff, sparingly streaked and spotted with reddish brown and bluish grey, the latter colour 
appearing as if beneath the surface of the shell. 
The male has the crown of the head, lores, line beneath the eye, ear-coverts, and a crescent-shaped mark 
from the latter across the breast deep black; throat, within the black, white; back of the neck, a narrow 
line down each side of the chest behind the black crescent, and all the under surface gamboge-yellow ; 
back and upper tail-coverts yellowish olive ; wing-coverts blackish brown, margined with yellowish olive ; 
primaries and secondaries blackish brown, margined with greyish olive ; basal half of the tail grey, apical 
half blackish brown tipped with grey ; irides dark brown ; bill black; legs and feet blackish grey. 
The female has the whole of the upper surface and tail greyish brown; primaries and secondaries brown, 
margined with grey; throat pale brown freckled with white ; remainder of the under surface pale brown, 
passing into deep buff on the abdomen. 
The Plate represents the two sexes of the natural size.
