PETROICA FUSCA, Gowda. 
Dusky Robin. 
Tuts unadorned species of Robin is very abundantly distributed over all those parts of Van Diemen’s Land 
that are suitable to its habits ; it gives preference to thinly-timbered hills, and all such plains and low 
grounds as are sterile and covered here and there with thickets and stunted brushwood. In its manners 
and whole economy it closely assimilates to the Red-breasted Robins ; I frequently observed it sitting on the 
stumps of dead and fallen trees, on the railings of inclosures, gardens and other similar situations. — Its 
food appeared to consist solely of insects, which it swallows entire, even coleoptera of a large size. 
Its nest, which is rather large and of a cup-shape, is formed of coarse fibrous roots, small twigs, strings of 
bark and dried grasses intermixed with very fine hair-like fibrous roots, wool, and the soft seed-stalks of 
mosses. ‘The size and form of the nest depend upon the nature of the situation chosen for a site; if a 
ledge or fissure of a rock, it is much spread out, but with the inside and top very neatly finished ; the opening 
measures on an average about two inches and a half, and the nest is about one inch and a quarter in depth. 
The eggs, which are three or four in number, differ in colour from those of every other member of the 
genus, but more nearly assimilate in tint and markings to those of Peéroica bicolor than of any other. They 
are of a light greenish blue, freckled and spotted with minute indistinct markings of brown ; their medium 
length is ten lines, and breadth seven and a half lines. 
Although I have paid considerable attention to the distribution of this species, I have never been able to 
meet with it on the continent of Australia, or in any other country than Van Diemen’s Land; still 1 cannot 
positively assert that it is not an inhabitant of the Australian continent. It is very numerous about Hobart 
Town, both in the gulleys under Mount Wellington, and on the opposite side of the Derwent towards 
Clarence Plains. 
Its note is low and monotonous, without any peculiar character. 
The sexes differ from all the other members of the genus in being alike in colour, and cannot possibly 
be distinguished without the aid of dissection. 
Head, and all the upper surface reddish brown tinged with olive ; wings and tail brown; primaries and 
secondaries crossed by a narrow line of white at the base; the outer tail-feather on each side margined 
externally, and at the tip with white; under surface pale brown, passing into buffy white on the vent and 
under tail-coverts ; irides, bill and feet blackish brown. 
The young is very dark brown above, striated with deep buff; beneath mottled brown and buffy white ; 
the latter colour occupying the centre of the feathers. 
The Plate represents a male and two young birds of the natural size.
