Yellow Robin, Colonists of New South Wales. 
This is a very common species in all the brushes of New South Wales ; I also observed it in most of the 
gardens in the neighbourhood of Sydney, as well as in those of the settlers in the interior. It is very 
Robin-like in its actions, particularly in the habit of raising its tail at the moment of perching, and in 
the sprightly air with which it moves about. It is by no means shy, and may often be seen crossing the 
garden walks, perching on some stump or railing, regardless of one’s presence, at which time the fine yellow 
mark on its rump is very conspicuous. Its powers of flight are hut feeble, and are seldom employed to do 
more than enable it to flit from bush to bush or from tree to tree, in a peculiarly quiet Robin-like manner ; 
never displaying the restless activity of the Pardalotes, Acanthizas, and many other tribes of birds. Its food 
consists entirely of insects, which are more frequently taken on the ground than on the trees. 
It breeds in September and October. The nest is a beautiful, compact, round, cup-shaped structure, 
about three inches in diameter and an inch and a half deep, composed of narrow strips of bark, wiry fibrous 
roots, and in some instances grasses ; the outside held together with cobwebs, and sparingly speckled over 
with mouse-eared lichen and small pieces of hark, hanging loosely about it ; the inside of the nest is ge- 
nerally lined with leaves, but occasionally with portions of the broad blades of grasses. It is generally 
placed in the fork of some low tree in an open or exposed part of the brush, is a neat structure, and some- 
times so nearly resembles the bark of the tree upon which it is constructed, that it is almost impossible 
to detect it, so extraordinary is the instinctive power of imitation with which the bird has been endowed. 
The eggs are usually two in number, of a bright apple-green, speckled and spotted all over with chestnut- 
brown and blackish brown, the latter tint being much less conspicuous than the former ; they are nine lines 
long by seven and a half lines broad. 
It is not migratory, and so far as is known, is confined to the southern and eastern portion of the country. 
The sexes are alike in colour, but the female is somewhat smaller in size : the young on leaving the nest 
has the plumage streaked and spotted very similar to that of young Robins, but obtains the plumage of the 
adult at an early period. 
Head and all the upper surface, wings and tail, with the exception of the rump, very dark grey ; chin 
white ; all the under surface and rump wax-yellow ; irides, bill and feet black. 
The figures are of the natural size.
