BROWN HAWK. 
species ; one specimen has a pale, almost white, breast, and a remarkably 
rufous upper-surface.” 
North, in the Aiistr. Mus. Spec. Cat., No. 1, Vol. III., p. 279, 1912, 
gives Dr. Macgillivray’s conclusion from Broken Hill, South-western New 
South Wales : “ The lighter Brovm Hawk {Hieracidea berigora) appears to 
shade into the other species, H. orientalis. Several nests have been found, 
but are indistinguishable from those of the common bird. It occurs, I should 
think, in about the proportion of one to two hundred of the other, and its 
habits and general economy are the same.” 
A. G. Campbell, in the Emu, Vol. II., p. 205, 1903, under the name 
Hieracidea berigora, gave this note : “A trait exhibited by this species on 
King Island shows that there is no fear of man, induced when in undisturbed 
retreats. A brooding bird did not leave her nest, although four MelitJirepti 
were shot from the leafy tops of the tree in which it was placed. During 
the journey across Bass Strait one of these Hawks was noticed following 
the steamer. It appeared to have been on the wing for some time, and was 
flying heavily. On endeavouring to perch on the tafl-rail of the boat, a 
strong gust of wind swept it into the water, where the poor thing was left to 
its fate.” 
Berney, writing of Hieracidea berigora in the Richmond District, North 
Queensland {Emu, Vol. V., p. 18, 1905), notes: “Is one of the commonest 
Hawks we have, and at the same time the most foolishly confiding. Perched 
on the upper limb of a dead tree, it will allow a close inspeetion to be made 
by anyone walking round just below, and screwing its head round as it 
follows your movements. General food appears to be grasshoppers, centipedes, 
lizards, et hoc genus omne. I never saw them tackle a live bird, though on one 
occasion I did see one after a Native Hen {Tribonyx ventralis) on a claypan 
flat where there was no shelter for the Tribonyx. If it wanted to catch the 
latter it was making a very poor show, but if, on the other hand, it was 
only having a ‘ lark,’ then it was frightening the life out of the fowl. Of\\fchis 
and the succeeding species {Hieracidea orientalis) it is hard to say which is 
the more numerous here. I am inclined to say the present bird is, although 
supposed to be the more Western form. A nest that I inspeeted 12th 
November, 1902, contained a single chick. They are at times verv much 
more numerous than at others, but this, I think, is due to the sort of 
season we are having : to the scarcity or abundance of certain food.” 
Hill, from the North-west of Victoria {Emu, Vol. VI., p. 177, 1907), 
wrote : “ Only one specimen was identifled, though no doubt the apparent 
scarcity may be due to the fact that for some years I believed that there was 
only one species of this genus in the locality.”
