The male has the head, cheeks, and back of the neck deep brownish black;

the feathers of the upper surface, wings and tail alternately crossed

with equal-sized bands of deep grey and blackish brown; outer edges of

the primaries uniform blackish brown, their inner webs obscurely barred

with light buff; throat and chest delicate fawn-colour, passing into

reddish grey on the abdomen; tail-feathers ornamented with an

oval-shaped spot of dark brown; abdomen, flanks, under surface of the

wing, and under tail-coverts reddish grey, crossed by numerous irregular

bars of blackish brown; bill light bluish lead-colour at the tip,

becoming much lighter at the base; cere, legs and feet yellow; claws

black.

The female differs from the male in being larger in all her proportions,

and in having the throat and chest more richly tinted with fulvous,

which colour also extends over the abdomen, the feathers of which are

not so strongly barred with brown as in the male.

The figures are those of a male and a female of the natural size.

All that I am able to communicate respecting this rare species of Falcon

is that I have seen four examples, which were killed in South Australia;

no particulars of its habits have yet been recorded: it was observed by

Captain Sturt during his expedition into the interior of that country,

and he has favoured me with a note, in which he says, “This well-shaped

and rapid bird was killed at the Depôt, where both male and female were

procured, but it was by no means common, only two others having been

seen.”

It is a fine and powerful species, and is doubtless very destructive to

birds and the smaller quadrupeds.

The entire plumage dark sooty brown, becoming paler on the edges of the

feathers of the upper surface; chin whitish; irides dark brown; cere

yellow; bill lead-colour; legs and feet leaden yellow; claws black.

_Little Falcon_, Colonists of Western Australia.

This, one of the least of the true Falcons found in Australia, is

universally spread over the southern portion of that country, including

Van Diemen’s Land and the islands in Bass’s Straits. As its long pointed

wings clearly indicate, it possesses great and rapid powers of flight;

and I have frequently been amused by pairs of this bird following my

course over the plains for days together, in order to pounce down on the

Quails as they rose before me. If I had wished to witness Falconry in

perfection I could not have had a better opportunity than on these

occasions, when it was interesting to observe how instinctively the

Falcons performed their gyrations just above the dogs, in preparation

for the stoop; and on those vast plains where there was not a tree or

any other object to obstruct either the flight of the bird or our view

of the chase, nothing could be more beautiful in its way than the

actions of this species when pursuing the swift-flying Quail, which,

although quickly overtaken, often evades the stroke of its enemy by

suddenly dropping to the ground among the grasses.

The White-fronted Falcon is not a migratory species in any of the

colonies. I succeeded in finding several of its nests, both in Van

Diemen’s Land and on the continent: the situations of all those I

observed were near the tops of the most lofty and generally inaccessible

trees; they were rather large structures, being fully equal in size to

that of a Crow, slightly concave in form, outwardly built of sticks, and

lined with the inner bark of trees and other soft materials: the eggs

are either two or three in number, of a light buff, blotched and marbled

all over with dark buff, one inch and ten lines long by one inch and

four lines broad.

The stomach is rather muscular and capacious, and its food consists of

small birds and insects.

Forehead greyish white; crown of the head, cheeks, ear-coverts, and all

the upper surface uniform dark bluish grey; internal webs of the

primaries, except the tips, numerously barred with oval-shaped markings

of buff; two centre tail-feathers grey, transversely barred with obscure

markings of black; the remainder of the feathers on each side

alternately barred with lines of dark grey and reddish chestnut; throat

and chest white, tinged with buff, the feathers of the chest marked down

the centre with a stripe of brown; the whole of the under surface and

thighs dull reddish orange; irides blackish brown; bill bluish

lead-colour, becoming black at the tip; cere, base of the upper

mandible, legs and feet yellow; claws black.

The sexes exhibit the usual difference in size, the female being much

the largest. The plumage of the young differs from that of the adult in

being more rusty and the markings less defined, in the feathers of the

wings and tail being margined with rufous, and in the whole of the under

surface being washed more deeply with rufous than the adult.

The Plate represents an adult and young bird of the natural size.

_Brown Hawk_, Colonists of Van Diemen’s Land.

This species is universally distributed over Van Diemen’s Land and New

South Wales. It is represented in western and north-western Australia by

a nearly allied species, to which I have given the name of

_occidentalis_. In its disposition it is neither so bold nor so daring

as the typical Falcons, and while it partakes much of the habits and

actions of the true Kestrils, particularly in the mode in which it

hovers in the air, it also often soars and skulks about after the manner

of the Harriers. Although it sometimes captures and preys upon birds and

small quadrupeds, its principal food consists of carrion, reptiles and

insects; the crops of several that I dissected were literally crammed

with the latter kind of food. It is generally to be met with in pairs,

but at those seasons when hordes of caterpillars infest the newly-sprung

herbage it congregates in flocks of many hundreds; a fact I myself

witnessed during the spring of 1840, when the downs near Yarrundi, on

the Upper Hunter, were infested with this noxious insect, which spread

destruction throughout the entire district. By the settlers this bird is

considered one of the pests of the country, but it was clear to me that

whatever injury it may inflict by now and then pilfering the

newly-hatched chickens from the poultry-yard is amply compensated for by

the havoc it commits among the countless myriads of the destructive

caterpillar. After the morning meal it perches on the dead branches of

the neighbouring _Eucalypti_ until hunger again impels it to exert

itself for a further supply. To give an idea of the numbers of this bird

to be met with at one time, I may state that I have frequently seen from

ten to forty on a single tree, so sluggish and indisposed to fly that

any number of specimens might have been secured.

So much difference occurs in the plumage of this species, that unless

the changes it undergoes are known to him, the ornithologist would be

apt to consider that there were more than one species; a close attention

to the subject has, however, convinced me that the contrary is the case,

and that in the countries which I have stated to constitute the true

habitat of this bird there is but one species. During the first autumn

the dark markings are of a much deeper hue, and the lighter parts more

tinged with yellow than in the adult state, when the upper surface

becomes of a uniform brown, and the white of the under surface tinged

with yellow.

The sexes are nearly alike in colour, but the female is the largest in

size. I discovered the _Ieracidea Berigora_ breeding in the months of

October and November both in Van Diemen’s Land and New South Wales, the

nests in both countries being placed on the highest branches of the

lofty _Eucalypti_.

The nest is similar in size to that of a Crow, it is composed outwardly

of sticks, and lined with strips of stringy bark, leaves, &c.; the eggs,

which are two, and sometimes three in number, vary so much in colour,

that they are seldom found alike, even in the same nest; they are also

longer or of a more oval shape than those of the generality of Falcons;

the prevailing colour is,—the ground buffy white, covered nearly all

over with reddish brown: in some specimens an entire wash of this colour

extends over nearly half the egg, while in others it is blotched or

freckled in small patches over the surface generally: their medium

length is two inches and two lines, and breadth one inch and six lines.

Crown of the head ferruginous brown, with a fine black line down the

centre of each feather; a streak of black from the base of the lower

mandible down each side of the cheek; ear-coverts brown; throat, chest,

centre of the abdomen, and under tail-coverts pale buff, with a fine

line of brown down each side of the shaft of every feather; flanks

ferruginous, each feather crossed with spots of buffy white; thighs dark

brown, crossed like the flanks but with redder spots; centre of the back

reddish brown; scapularies and wing-coverts brown, crossed with

conspicuous bars and spots of ferruginous; tail brown, crossed with

ferruginous bars, and tipped with light brown; primaries blackish brown,

margined on their inner webs with large oval-shaped spots of buff; bill

light lead colour, passing into black at the tip; cere and orbits pale

bluish lead colour; irides very dark brown; feet very light lead-colour.

The figures represent the two sexes of the natural size.

Western Brown Hawk.

_K̏ar-gyne_, Aborigines of the lowland and mountain districts of

Western Australia.

Hitherto ornithologists, and among them myself, have regarded the Common

Brown Hawks, which occur so numerously in collections from Australia, as

referrible to one and the same species,—an opinion founded principally

upon the circumstance of the members of this genus being subject to a

greater number of changes of plumage from youth to maturity than any

other; observation, however, aided by dissection, and that too of very

many examples, and at all seasons of the year, has convinced me that

there are two species, which appear to occupy opposite portions of the

continent; the present bird, as its name implies, being confined to the

western, and the _I. Berigora_ to the eastern. Both species are

occasionally found in South Australia, but the latter is the most

abundant, and here it would seem that they inosculate.

The present bird is very generally spread over the Swan River

Settlement, and in its habits and economy closely assimilates to its

representative in New South Wales. It feeds upon birds, lizards,

insects, caterpillars, and carrion. Its smaller size renders it a

somewhat less formidable enemy to the farm-yard, still it requires

considerable vigilance to check its depredations upon the broods of

poultry, ducks, &c.

As its smaller legs, more compact body and lengthened pointed wings

would indicate, it flies with ease, making long sweeps and beautiful

curves, which are often performed near the ground. It loves to dwell

among swampy places, which at all times afford it an abundant supply of

lizards, frogs, newts, &c.

It breeds in September and October.

The nest is formed of dried sticks and is usually constructed in thickly

foliaged trees, sometimes near the ground, but more frequently on the

topmost branches of the highest gums; the eggs, which are generally two,

but sometimes three in number, differ very much in their markings, the

rich brown pervading the surface in some more than in others; those in

my collection measure two inches long by one and a half broad.

Crown of the head, back and scapularies rusty brown, with a narrow

stripe of black down the centre; rump deep rusty brown, crossed by broad

bands of dark brown, the tip of each feather buffy white; wings very

dark brown; the inner webs of the primaries with a series of large

spots, assuming the form of bars of a deep rusty brown near the shaft,

and fading into buffy white on the margin; wing-coverts tipped with

rusty red; spurious wing with a row of rusty spots on either side of the

shaft; tail dark brown, crossed by numerous broad irregular bars of

rusty red, and tipped with pale buff; ear-coverts and a stripe running

down from the angle of the lower mandible dark brown; chin, all the

under surface, and a broad band which nearly encircles the neck pale

buffy white, with a fine line of dark brown down the centre; thighs deep

rust-red, each feather with a line of black down the centre and tipped

with buffy white; irides reddish brown; eyelid straw-yellow; orbits

bluish flesh-colour; bill bluish lead-colour, becoming black at the tip;

cere pale yellow; legs and feet light ashy grey, excepting the scales in

front of the tarsi, which are dull yellowish white.

The Plate represents an adult male and female rather less than the size

of life.

TINNUNCULUS CENCROÏDES

Nankeen Kestril.

_Nankeen Hawk_, of the Colonists.

Ornithologists will not fail to observe how beautifully the present bird

represents in Australia the well-known Kestril of the British Islands,

to which it closely assimilates in many of its actions and in much of

its economy.

So far as is yet known, this elegant Kestril is not only confined to

Australia, but its habitat is even restricted to the south-eastern

portion of that continent. I observed it to be tolerably abundant in

every part of New South Wales, and also on the plains of the interior in

the neighbourhood of the river Namoi. A large collection of birds from

South Australia, kindly forwarded to me by T. C. Eyton, Esq., also

contained examples.

Mr. Caley states that it is a migratory species, but I am inclined to

differ from this opinion; his specimens were procured in New South Wales

in May and June, while mine were obtained at the opposite season of

December, when it was breeding in many of the large gum-trees on the

rivers Mokai and Namoi; probably some districts are deserted for a short

time, and such others resorted to as may furnish it with a more abundant

supply of its natural food, and this circumstance may have led him to

consider it to be migratory.

The flight of the Nankeen Kestril differs from that of its European ally

in being more buoyant and easy, the bird frequently suspending itself in

the air without the slightest motion of the wings: it also flies much

higher, and having arrived at a great height flies round in a series of

circles, these flights being often performed during the hottest part of

the day; a circumstance which leads me to suppose that some kind of

insect food was the object of the search, it being well known that in

mid-day insects ascend to a much greater altitude than at any other

time.

The sexes present the usual differences in their markings, the female

having all the upper surface alternately barred with buff and brown,

while the male is furnished with a more uniform tint. I once took four

fully-fledged young from the hole of a tree by the side of a lagoon at

Brezi, in the interior of New South Wales; I also observed nests which I

believe were constructed by this bird, but which were placed on the

branches in the ordinary way of the members of this group.

The male has the forehead white; head and back of the neck reddish grey,

with the shaft of each feather black; back, scapularies and wing-coverts

cinnamon-red, with a small oblong patch of black near the extremity of

each feather; primaries, secondaries and greater coverts dark brown,

slightly fringed with white; the base of the inner webs of these

feathers white, into which the dark colouring proceeds in a series of

points, resembling the teeth of a large saw; face white, with a slight

moustache of dark brown from each angle of the mouth; chest and flanks

buffy white, with the shaft of each feather dark brown; abdomen and

under tail-coverts white; upper tail-coverts and tail-feathers for

two-thirds of their length from the base grey; remaining portion of all

but the two centre feathers white, crossed near the tip by a broad

distinct band of deep black, the band being narrow, and only on the

inner web of the external feather; bill horn-colour near the base, black

towards the tip; base of the under mandible yellowish; cere and orbits

yellowish orange; legs orange.

The female has all the upper surface, wings and tail cinnamon-red; each

feather of the former with a dark patch of brown in the centre, assuming

the shape of arrow-heads on the wing-coverts; the scapularies

irregularly barred with the same, and the tail with an irregular band

near the extremity; throat, vent and under tail-coverts white; remainder

of the under surface reddish buff, with a stripe of brown down the

centre of each feather.

The figures represent the two sexes of the natural size.

The only part of Australia in which I have met with this species is New

South Wales, where it would appear to evince a preference for the dense

and luxuriant brushes near the coast; but so little has at present been

ascertained respecting its economy, range and habits, that its history

is nearly a blank—even whether it is migratory or not is unknown. That

it breeds in the brushes of the district above mentioned is certain, for

I recollect seeing a brood of young ones in the possession of Alexander

Walker Scott, Esq., of Newcastle on the Hunter, a gentleman much

attached to the study of the natural productions of Australia. These

young birds differed but little in colour from the fully adult specimens

in my collection, except that the transverse markings of the breast were

much darker and of a more arrow-shaped form; which markings become

fainter and more linear as the bird advances in age.

The sexes present the usual difference in size, but in colour and

markings they closely assimilate.

All the upper surface grey; throat and all the under surface white,

crossed with numerous irregular grey bars; cere yellowish orange; feet

yellow; bill and claws black.

The irides of the young are brown.

The figures represent the two sexes of the natural size, the smaller

bird being the male.

Although I feel convinced that the white bird to which the name _Falco

Novæ-Hollandiæ_ has been constantly applied by the older writers is

merely an albino of the species figured on the preceding plate, I have

been induced to give a representation of it here, in order to show what

synonyms have reference to that state of plumage, as well as to depict

one of the most ornamental and beautiful of the _Falconidæ_ inhabiting

Australia. As I have before stated, the range of the grey bird would

seem to be confined to New South Wales: on the other hand, the white

bird is not only found in the same districts, but is also very

generally, though sparingly, distributed over Van Diemen’s Land, a fact

which might induce many persons to consider it to be a distinct species;

I am however inclined, with Cuvier, to believe it to be merely an albino

variety, now become permanent,—an event of very rare occurrence among

animals in a state of nature. The diversity in the colouring of the

irides of the many individuals that have come under my notice would

materially tend to confirm this opinion, some having the irides bright

yellow, and others brown; a splendid female I shot under Mount

Wellington in Van Diemen’s Land had the irides bright crimson, like

those of the albinos of many other animals; while another equally fine

female, in the possession of the Hon. Henry Elliot, at Government House,

had the irides bright yellow.

In the size and admeasurements of the various parts of either sex of the

white and grey birds no difference whatever can be detected, another

reason for believing them to be the same; for wherever a specific

difference is found to exist, it is always accompanied by a difference

in the dimensions of the whole or parts of the structure.

A knowledge of the nidification of this and the preceding bird, and of

the state of their plumage from youth to maturity, would greatly tend to

settle the question of their identity.

The disposition of Mr. Elliot’s bird was fierce and wild in the extreme,

exhibiting none of the docility of the true Falcons, but displaying all

the ferocity so characteristic of the group to which it belongs.

The sexes differ very considerably in size, the male being scarcely more

than half the size of the female.

The whole of the plumage pure white; cere and legs yellow; bill and

claws black.

The figures represent the two sexes of the natural size.

The bird here represented I conceive to be the true _Falco radiatus_ of

Latham; it is but little known to ornithologists, from the circumstance

that few specimens only have been sent to Europe. It inhabits the dense

brushes bordering the rivers Manning and Clarence on the eastern coast

of New South Wales, and doubtless enjoys a much greater range than we

are at present acquainted with. It is the largest of the Goshawks

inhabiting Australia, far exceeding in size the _Astur palumbarius_ of

Europe. In some parts of its structure it differs considerably from the

typical Asturs, particularly in the lengthened form of the middle toe,

in which respect it resembles the true Accipiters; in its plumage it

somewhat differs from both those forms, the markings of most of the

feathers taking a longitudinal instead of a transverse direction; these

differences may hereafter be considered of sufficient importance to

warrant its separation into a distinct genus, but for the present I have

retained it with the other Goshawks in that of _Astur_. Of its habits

and economy nothing whatever is known.
