It would seem that the whole extent of the southern coast of Australia

is inhabited by the present species, for on comparing adult males from

New South Wales, South Australia and Swan River, I find that they do not

differ in any respect; the apical half of the tail is blackish brown in

all, and the colouring of the under surface of the richest yellow. It is

rather abundantly dispersed over the forests of _Eucalypti_ and the

belts of _Acaciæ_, among the flowering branches of which latter tribe of

trees the male displays himself to the greatest advantage, and shows off

his rich yellow breast as if desirous of outvieing the beautiful

blossoms with which he is surrounded.

The stomach is very muscular, and its principal food consists of insects

of various genera, which are sought for and captured both among the

flowers and leaves as well as on the ground.

It is generally met with in pairs, but the males are more shy than the

females. It flies in short and sudden starts, and seldom mounts far

above the tops of the trees.

The voice of the male is a single note seven or eight times repeated,

and terminating with a sharp higher note much resembling the smack of a

whip; that of the female is very different, being a series of running

half-notes, forming a rather plaintive tune.

Mr. Gilbert mentions that it is sparingly dispersed throughout the Swan

River colony, but is more abundant in the best-watered districts, such

as Perth and Fremantle.

I did not succeed in finding the nest of this species, but was informed

that it breeds in September and October, and lays three or four eggs,

ten and a half lines long by eight lines broad, with a ground-colour of

brownish buff, sparingly streaked and spotted with reddish brown and

bluish grey, the latter colour appearing as if beneath the surface of

the shell.

The male has the crown of the head, lores, line beneath the eye,

ear-coverts, and a crescent-shaped mark from the latter across the

breast deep black; throat, within the black, white; back of the neck, a

narrow line down each side of the chest behind the black crescent, and

all the under surface gamboge-yellow; back and upper tail-coverts

yellowish olive; wing-coverts blackish brown, margined with yellowish

olive; primaries and secondaries blackish brown, margined with greyish

olive; basal half of the tail grey, apical half blackish brown tipped

with grey; irides dark brown; bill black; legs and feet blackish grey.

The female has the whole of the upper surface and tail greyish brown;

primaries and secondaries brown, margined with grey; throat pale brown

freckled with white; remainder of the under surface pale brown, passing

into deep buff on the abdomen.

The Plate represents the two sexes of the natural size.

PACHYCEPHALA GLAUCURA, _Gould_.

Grey-tailed Pachycephala.

_Pachycephala glaucura_, Gould, in Proc. of Zool. Soc., March 25,

1845.

_Pe-dil̈-me-dung_, Aborigines of the lowland districts of Western

Australia.

Although the present bird is very nearly allied to the _P. gutturalis_,

it may be readily distinguished from that species by its larger size, by

its shorter and more robust bill, by the uniform grey colouring of its

tail, and by the lighter and more washy tint of the yellow of the under

surface. Van Diemen’s Land and the islands in Bass’s Straits are the

only countries in which it has yet been discovered, and where it takes

the place of the _P. gutturalis_, which latter species appears to be

exclusively confined to the Australian continent.

The _P. glaucura_ frequents the vast forests of _Eucalypti_ that cover

the greater part of Van Diemen’s Land, and although it is rather thinly

dispersed, is to be met with in every variety of situation, the crowns

of the hills and the deep and most secluded gulleys being alike visited

by it. It frequently descends to the ground in search of insects, but

the leafy branches of the trees, particularly those of a low growth, are

the situations to which it gives the preference.

The adult male, like most other birds of attractive plumage, is of a shy

disposition; hence there is much more difficulty in obtaining a glimpse

of it in the woods, than of the sombre-coloured and comparatively tame

female, or even of the young males of the year, which during this period

wear a similar kind of livery to that of the latter.

The actions of this species are somewhat peculiar, and unlike those of

most other insectivorous birds: it pries about the leafy branches of the

trees, and leaps from twig to twig in the most agile manner possible,

making all the while a most scrutinizing search for insects,

particularly coleoptera. When the male exposes himself, as he

occasionally does, on some bare twig, the rich yellow of his plumage,

offering a strong contrast to the green of the surrounding foliage,

renders him a conspicuous and doubtless highly attractive object to his

sombre-coloured mate, who generally accompanies him. Males in colour

like those represented on the accompanying Plate seldom associate

together, their recluse disposition leading them not only to avoid each

other’s society, but also that of all other birds. It sometimes resorts

to the gardens and shrubberies of the settlers, but much less frequently

than might be supposed, when we consider that the neighbouring forests

are its natural place of abode.

The voice of the Grey-tailed Pachycephala is a loud whistling call of a

single note several times repeated, and by which the presence of the

male is often detected when it would otherwise be passed by unnoticed. I

was unsuccessful in my search for its nest, and the eggs are still a

desideratum to my cabinet. I shot the young in various stages of

plumage, and found them to differ so much that a more, than ordinarily

minute description is necessary, in order that those who may not have an

opportunity of seeing the bird in its native country may not be misled

respecting it. Soon after leaving the nest the ground-colour of the

entire plumage is grey, washed or stained as it were, both on the upper

and under surface, with rusty or chestnut-red; this gradually gives

place to a uniform olive-brown above and pale brown beneath, which being

precisely the colouring of the adult females, the young birds in this

stage and the old females are not to be distinguished from each other.

The adult male has the crown of the head, lores, space beneath the eye

and a broad crescent-shaped mark from the latter across the breast deep

black; throat, within the black, white; back of the neck, a narrow line

down each side of the chest behind the black crescent and the under

surface yellow; back and wing-coverts yellowish olive; wings dark

slate-colour margined with grey; tail entirely grey; under tail-coverts

white, or very slightly washed with yellow; irides reddish brown; bill

black; feet dark brown.

The Plate represents two males and a female of the natural size, on one

of the common Acacias of Van Diemen’s Land.

PACHYCEPHALA MELANURA, _Gould_.

Black-tailed Pachycephala.

_Pachycephala melanura_, Gould in Proc. of Zool. Soc., Part X. p. 134.

The _Pachycephala melanura_ is a native of the northern coasts of

Australia, where it was procured by B. Bynoe, Esq., during the surveying

voyage of H.M.S. the Beagle. It may be readily distinguished from the

_P. gutturalis_ and _P. glaucura_ by the jet-black colouring of the

tail, which organ is also shorter and more square than that of any other

species, by its much longer bill, and by the colouring of the back of

the neck and the under surface being richer than that of either of those

above-named. I have not yet seen a female of this fine species, wanting

which I have figured two males in different positions.
