This fine species was first described and figured in the “Illustrations

of Ornithology,” by Sir William Jardine 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. Bynoe and Dring; 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.
