Satin Bird, of the Colonists of New South Wales. 
Cowry, of the Aborigines of the coast of New South Wales. 
Aurnoucn this species has been long known to ormthologists, and is familiar to the colonists of New South 
Wales, its habits, which in many respects are most extraordinary, haye hitherto escaped attention; or if 
not entirely so, have never been brought before the scientific world, Itis, therefore, a source of high grati- 
fication to myself to be the first to place them on record. 
One point to which I more particularly allude,—a point of no ordinary interest, both to the naturalist and 
the general admirer of nature, 
is the formation of a bower-like structure by this bird for the purpose of 
a playing-ground or hall of assembly, a circumstance in its economy which adds another to the many 
anomalies connected with the Fauna of Australia. 
The localities favourable to the habits of the Satin Bower-bird are the luxuriant and thickly-foliaged 
brushes stretching along the coast from Port Philip to Moreton Bay, the cedar-brushes of the Liverpool 
range, and most of the gullies of the great mountain-cham separating the colony from the interior. So far 
as is at present known, it is restricted to New South Wales ; certainly it is not found so far to the westward 
as South Australia, and | am not aware of its having been seen on the north coast; but its range in that 
direction can only be determined by future research. 
It is a stationary species, but appears to range from one part of a district to another, either for the 
purpose of varying the nature, or of obtaining a more abundant supply of food. Judging from the 
contents of the stomachs of the many specimens I| dissected, it would seem that it is altogether granivo- 
rous and frugiyorous, or if not exclusively so, that msects form but a small portion of its diet. Inde- 
pendently of numerous berry-bearing plants and shrubs, the brushes it inhabits are studded with enormous 
fig-trees, some of them towering to the height of two hundred feet; among the lofty branches of these 
giants of the forest, the Satin Bower-bird and several species of Pigeons find in the small wild fig, with 
which the branches are loaded, an abundant sapply of a fayourite food: this species also commits con- 
siderable depredation on any ripening corn near the localities it frequents, It appears to have particular 
times in the day for feeding, and when thus engaged among the low shrub-like trees, | have approached 
within a few feet without creating alarm; but at other times I have found this bird extremely shy and 
watchful, especially the old males, which not unfrequently perch on the topmost branch or dead limb of the 
loftiest tree in the forest, whence they can survey all round, and watch the movements of the females and 
young in the brush below. 
In the autumn they associate in small flocks, and may often be seen on the ground near the sides of 
rivers, particularly where the brush descends in a steep bank to the water's edge. 
Besides the loud liquid eall peculiar to the male, both sexes frequently utter a harsh, unpleasant, guttural 
note indicative of surprise or displeasure. The old black males are exceedingly few in number, as compared 
with the females and young male birds in the green dress, from which and other circumstances I am Jed to 
believe that at least two, if not three years, elapse before they attain the rich satin-like plumage, which, 
when once perfectly assumed, is, | believe, never again thrown off. 
I regret to state, that although [ used my utmost endeavours, [ could never discover the nest and eggs 
of this species, neither could 1 obtain any authentic information respecting them, either from the natives or 
the colonists, of whom I made frequent inquiries. 
The extraordinary bower-like structure, alluded to above, first came under my notice at Sydney, to the 
Museum of which place an example had been presented by Mr. Charles Coxen, as the work of the Satin 
Bower-bird. Lat once determined to leave no means untried for ascertainmg every particular relating to 
this peculiar feature in the bird’s economy, and on visiting the cedar-brushes of the Liverpool range I dis- 
covered several of these bowers or playing-places; and a glance at the accompanying illustration will, I 
presume, give a more correct idea of the nature of these erections than the most minute description. They 
are usually placed ander the shelter of the branches of some overhanging tree in the most retired part of 
the forest: they differ considerably in size, some being a third larger than the one here represented, while 
others are much smaller. The base consists of an extensive and rather convex platform of sticks firmly 
interwoven, on the centre of which the bower itself is built: this, like the platform on which it is placed 
and with which it is interwoven, is formed of sticks and twigs, but of a more slender and flexible descrip-
