CHLAMYDERA C ERVINIVENTRIS, Gowa.

Fawn-breasted Bower-bird.

Chlamydera cerviniventris, Gould in Proc. of Zool. Soc., part xviii, p. 201.

 

Ir any one circumstance more than another would tend to hand down the name of the author of the “ Birds
of Australia” to posterity, it would be the discovery and the publication of the singular habits of the
Bower-birds. In figuring and describing, then, an additional species of this group of birds, I feel that I am
presenting to the notice of the ornithological world another of the most interesting birds with which we are
acquainted. The discovery of the present species is due to Mr. John MacGillivray, who procured a specimen
at Cape York, secured its curious bower, and transmitted both to the British Museum. The two formerly
known and nearly allied species being both conspicuously adorned with a lovely frill of liliaceous feathers
at the nape of the neck, I naturally supposed that the same kind of ornament would be found in all the
species; but it appears that such is not the case, for there is not a trace of it in any of the examples of
C. cerviniventris [have yet seen; and I believe some of them are very old birds. In size this species is
rather larger than C. maculata, or almost intermediate between that species and C. nuchalis; it has also a
similar character of markings on the back, but the brown spots are neither so large, so round, nor so deeply
coloured: the distinguishing feature of the present species is its rich, uniformly-coloured, buff under surface,
a feature which does not exist either in the C. maculata or C. nuchalis. The bower differs very remarkably
from those of the other two species; it is about 13 inches long and 10 or 11 inches high; its walls, which
are very thick, are nearly upright, or but little inclining towards each other at the top, so that the passage
through is very narrow. ‘This elevated structure, which is formed of fine twigs, is placed on a very thick plat-
furm of thicker twigs, nearly 4 feet in length and almost as much in breadth: here and there a small snail-
shell or berry is dropped in the way of decoration.

The following note relative to this bird is extracted from Mr. MacGillivray’s ‘* Narrative of the Voyage of
H.M.S. Rattlesnake :”’—

“Tyo days before we left Cape York, I was told that some Bower-birds had been seen in a thicket or
patch of low scrub, half a mile from the beach; and after a long search I found a recently-constructed
bower, 4 feet long and 18 inches high, with some fresh berries lying upon it. The bower was situated near
the border of the thicket, the bushes composing which were seldom more than 10 feet high, growing in
smooth sandy soil without grass.

«Next morning I was landed before daylight, and proceeded to the place in company with Paida, taking
with us a large board on which to carry off the bower as a specimen. I had great difficulty in inducing my
friend to accompany me, as he was afraid of a war party of Gomokudins, which tribe had lately given notice
that they were coming to fight the Evans Bay people. However, I promised to protect him, and loaded one
barrel with ball, which gave him increased confidence; still he insisted upon carrying a large bundle of
spears and a throwing-stick.

«While watching in the scrub, I caught several glimpses of the ¢ewnga (the native name) a it darted
through the bushes in the neighbourhood of the bower, announcing its presence by an occasional loud
churr-r-r, and imitating the notes of various other birds, especially the Leathenhead: I never before met
with a more wary bird ; and, for a long time, it enticed me to follow it to a short Gist then flying off and
alighting on the bower it would deposit a berry or two, run through and be off again Delome I could reach
the spot. All this time it was impossible to get a shot. At length, just as my patience was becoming
exhausted, I saw the bird enter the bower and disappear, when I fired at random through the twigs, for-
tunately with effect. So closely had we concealed ourselves latterly, co so silent had we been, that a
kangaroo, while feeding, actually hopped up within fifteen yards, UNgon scons of our preeaee a use e
My Bower-bird proved to be a new species, since described by Mr. Gould as Chlamydera cerviniventris ; anc
the bower is exhibited in the British Museum.”

When Mr. MacGillivray speaks of the bird alighting on the top of the bower, Ce mean on the plat-
form, as, from the fineness of the twigs of which the bower itself is constructed, with the weaker ends up-
wards, they could not support the weight of the bird.
