_Rose-hill Parrakeet_, Colonists of New South Wales.

The present beautiful bird ranks among the earliest of the natural

productions of Australia that were sent to Europe, but no information

having hitherto been published respecting its habits and economy, few

persons are aware that it is exclusively confined to New South Wales and

Tasmania, its occurrence even in South Australia being utterly unknown:

in the more distant colonies of Swan River and Port Essington it

certainly does not occur; but in each of those colonies it is

represented by a nearly allied species, whose habits and general economy

are as similar as possible. Although one of the commonest birds of New

South Wales and Van Diemen’s Land, it is very local, a river frequently

constituting the boundary of its habitat, over which it so rarely

passes, that I never, during my stay in the country, saw the bird on the

south side of the Derwent; while in the forests on the opposite shore,

not more than a quarter or half a mile distant, it was very numerous. I

believe it is never seen in the forests clothing the borders of

D’Entrecasteaux’ Channel on the south, or of the River Tamar on the

north of the island, those districts being inhabited by the _Platycercus

flaviventris_, whose greater size and olive-green plumage are in

beautiful accordance with those vast, and as yet unexplored forests of

evergreen _Eucalypti_. More delicate in its structure, and far more

brilliant in its plumage, the _Platycercus eximius_ resorts to the open

parts of the country, such as undulating grassy hills and plains

bordered and studded here and there with large trees or belts of low

acacias or banksias, among the branches of which, particularly those of

the acacias, this beautiful bird may be seen in small companies, the

rich scarlet and yellow of their breasts vieing with the lovely blossoms

of the trees; in a word, districts of a sandy nature, small plains, open

spots among the hills, and thinly timbered country where grass abounds,

constitute the peculiar and natural habitat of this bird: hence it is

not found to the north of the Derwent, where the country is of a

different character; but it is numerous throughout the centre of the

island between Hobart Town and Launceston, where small companies may

constantly be seen resorting to the public roads, like the Sparrow in

England, and upon being disturbed by the passer-by they merely fly off

to the nearest tree, or to the rails of the wayside fences. Scenes like

these fill the mind with sensations of no ordinary description, and

excite the greatest astonishment in those who have recently arrived in

the country; the novelty, however, as I have observed in numerous

instances, soon wears away, and a caged lark, linnet or blackbird from

the land of their birth would be highly cherished and valued, while the

beautiful productions of the island would be passed by unheeded, except

to deal out destruction among them, with no sparing hand, for some

slight injury they may have inflicted upon the rising corn. The above

remarks refer more particularly to Van Diemen’s Land, but apply with

equal force to New South Wales, where the bird inhabits all situations

similar in character to those above referred to. It breeds in great

abundance in Van Diemen’s Land and New South Wales; it is found in great

numbers in the district of the Upper Hunter, and was formerly very

numerous at Paramatta, particularly in the neighbourhood of Rose Hill,

whence its name. It lays from seven to ten beautiful white eggs in the

hollow of a gum-tree during October and the three following months; they

are one inch and an eighth long by seven-eighths of an inch broad.

Its natural food consists of seeds of various kinds, particularly those

of different grasses, and occasionally of insects and caterpillars.

Its flight is short and undulating, and is rarely extended to a greater

distance than a quarter of a mile, as the bird frequently alights on a

leafless branch, always flying a little below it and rising again just

before it settles.

Its note is a somewhat pleasing whistling sound, which is very

frequently uttered.

The sexes are alike in plumage, and the young assume the bright

colouring from the nest; the birds of the year, although they may have

attained their full size, are not so brilliant as the adult, and may

always be distinguished by the bill and nostrils being of a delicate

gamboge-yellow.

Specimens from Van Diemen’s Land are rather larger in size, and have the

markings of the upper surface of a greener yellow, and altogether less

brilliant than those from New South Wales: I possess a specimen killed

on Mosquito Island, at the mouth of the Hunter, which is more brilliant

than any other I have yet seen.

Crown of the head, back of the neck, chest, and under tail-coverts

scarlet; cheeks white; feathers of the back black, margined all round

with rich yellow; rump, upper tail-coverts, and lower part of the belly

pale green; centre of the belly yellow; shoulders and middle of the wing

rich blue; external edges of the primaries blue, the remainder of these

feathers dark brown; two middle tail feathers green, passing into bluish

green at the tip, the remainder of the tail-feathers dark blue at the

base, passing into light blue, and tipped with white; bill horn-colour;

feet brown; irides blackish brown.

The figures are of the natural size.

That the gradual investigation of the interior of Australia will lead to

the discovery of many new and interesting objects, is proved by the

recent acquisition of the lovely species here represented, which was

killed by Mr. Gilbert in the newly-located district to the northward of

the Darling Downs in New South Wales. In beauty it even exceeds the

Rose-Hill Parrakeet, and is consequently one of the finest species of

the genus yet discovered. It differs from that bird in having the centre

of the breast only of a rich scarlet, the sides being gamboge-yellow; in

the lower part of the abdomen and the upper tail-coverts being verditer

instead of grass-green, and in the feathers of the back being broadly

margined with rich gamboge instead of greenish yellow. In the youthful

state it very much resembles the _P. palliceps_, from which however it

differs in having the head yellow instead of pale yellowish white, and

the breast yellow instead of pale blue; the breast also has indications

of the rich scarlet of maturity, of which no trace is at any time

perceptible in the _P. palliceps_.

Head, sides of the neck and centre of the breast scarlet; cheeks white,

faintly tinged with blue; feathers of the back and scapularies black,

broadly margined with gamboge-yellow; lower part of the back and upper

tail-coverts pale green; on the shoulder a patch of black; wing-coverts

pale blue; primaries black with the exception of the basal portion of

the external web, which is rich deep blue; two central tail-feathers

dark green at the base, passing into deep blue on the apical half of the

external web and tipped with black; the next on each side is black on

the internal web, green at the base of the external web, blue for the

remainder of its length, and slightly tipped with white; the remainder

of the tail-feathers are deep blue at the base of the external, and

black at the base of the internal web, the remaining portion of both

webs being pale delicate blue, passing into white at the tip; sides of

the breast and the abdomen bright gamboge-yellow; vent pale green in

some, in others pale bluish green; under tail-coverts scarlet; irides

dark brown; bill horn-colour; feet mealy brown.

The figures are of the natural size, one representing the plumage of

youth, the other that of maturity.
