CHLAMYDERA NUCHALIS. 
Great Bower-bird. 
Ptilonorliynchus nuchalis, Jard. and Selb. 111. Orn., vol. ii. pi. 103. 
Calodera nuchalis, Gould, Syn. Birds of Australia, Part I. 
Chlamydera nuchalis, Gould, Birds of Australia, 1837, Part I. cancelled.— G. R. Gray, List of Gen. of Birds, p. 40. 
This fine species was first described and figured in the “ Illustrations of Ornithology,” by Sir William Jar- 
dine and Mr. Selby, from the then unique specimens in the collection of the Linnean Society ; but neither 
the part of Australia of which it is a native or any particulars relative to its habits were known to those 
gentlemen, nor have I myself had an opportunity of observing it in a state of nature, the bird being an 
inhabitant of the north-west coast, a portion of the Australian continent that has, as yet, been but little 
visited. I am indebted for individuals of both sexes of this bird to two of the officers of the “ Beagle,” 
Messrs. Bvnoe and Bring ; but neither of these gentlemen furnished me with any account of its economy. 
Captain Grey, however, on his return from his expedition to those regions, informed me that he frequently 
found during his rambles a most singular bower, made in every way like that of the Chlamydera maculata, 
and which was always an object of great interest to him, being unable to satisfy himself as to what animal 
had constructed it, or even whether it was the work of a bird or of a quadruped : he was inclined to 
suppose the latter, but I think there need not be the slightest hesitation in ascribing its formation to the 
Chlamydera nuchalis ; for we may reasonably expect that a species so very closely allied to that of the 
southern and eastern portions of the continent would partake of its peculiar habits and economy. The 
following notes were written on the spot, and were kindly given to me by Captain Grey : — 
“ These bowers were formed of dead grass and parts of bushes, sunk a slight depth into two parallel 
furrows, in sandy soil, and were nicely arched above ; but the most remarkable fact connected with them 
was, that they were always full of broken sea-shells, large heaps of which also protruded from each 
extremity of the bower. In one of these bowers, the most remote from the sea that we discovered, were 
found a heap of the stones of some fruit which had evidently been rolled in the sea. I never saw any 
animal in or near to these bowers, but the dung of a small species of Kangaroo was always abundant 
close to them, which induced me to suppose them to be the work of some kind of quadruped.” 
The circumstance of Captain Grey, never having perceived the birds near the runs, serves to show that it 
exhibits the same shyness of disposition as the other species. 
Head and all the upper surface greyish brown, the feathers of the former with a shining or satiny lustre ; 
the feathers of the back, wing-coverts, scapulars, quills and tail tipped with greyish white; on the nape of 
the neck a beautiful rose-pink fascia, consisting of narrow feathers, partly encircled by a ruff of satin-like 
plumes, the tips distinct, rounded, and turning inwards ; under surface yellowish grey, the flanks tinged 
with brown ; irides, bill and legs brownish black. 
In one of the specimens I possess, and which formed the subject of the upper figure in the Plate, no trace 
of the nuchal ornament is observable, a circumstance I conceive to be indicative of youth rather than a 
distinguishing characteristic of the sexes, since in the other species I find the mark common to both, but 
the young bird of the year without any trace of it. 
The Plate represents a male and a young bird, of the natural size.
