CAPRIMULGUS MACRURUS, _Horsf._

Large-tailed Goatsucker.

_Caprimulgus macrurus_, Horsf. in Linn. Trans., vol. xiii. p. 142.

This, the only true _Caprimulgus_ known to inhabit Australia, is I

believe identical with the _C. macrurus_ of Dr. Horsfield, whose

specimens were procured in Java, while those I possess were obtained at

Port Essington, where the bird is moderately plentiful; hence it would

appear that it has an unusually wide range of habitat. It inhabits the

open parts of the forest and is strictly nocturnal; it mostly rests on

the ground on the shady side of a large tree close to the roots, and if

disturbed several times in succession takes to the branch of one of the

largest trees. I have never seen the eggs of this species, but I possess

a young bird apparently only a few days old, which Mr. Gilbert found

lying under a shrubby tree, without any nest or even a blade of grass

near it; the little creature was so similar in colour to that of the

ground upon which it was lying, that it was with difficulty detected,

and Mr. Gilbert was only induced to search for it from the very peculiar

manner in which the old bird rose, the reluctance it evinced to leave

the spot, and its hovering over the place it had risen from, instead of

flying off to the distance of nearly a hundred yards, as it usually

does.

The sexes are distinguished from each other by the greater extent of the

white mark on the primaries and outer tail-feathers; in other parts of

the plumage and in size there is no difference.

Its food consists of moths, flies and coleopterous insects, which are

taken during flight.

Head brownish grey, very minutely freckled with black; the feathers down

the middle of the head and occiput with a large broad stripe of black

down the centre; lores, space surrounding the eyes and ear-coverts

reddish brown; on each side of the neck a broad stripe of rich buff

barred with black; a narrow line of white passes below the angle of the

mouth; chin brown; across the throat a band of white bounded below by

black, the extremities of the white feathers being of that hue; centre

of the back dark brown, freckled with black and buff; shoulders blackish

brown; wing-coverts freckled grey, buff and black, each with a large

spot of buff at the tip; primaries and secondaries blackish brown, the

former crossed at their base, and the latter throughout their entire

length, with reddish buff; the second and third primaries crossed near

their base with a broad band of white, stained with buff on the outer

margin; the first primary with a spot of white only on the margin of the

inner web; the first three primaries freckled at their tips, and the

remainder for the entire length of their inner webs with brownish grey;

scapularies freckled grey and brown, with a large patch of deep dull

black on their outer webs, margined externally with buff; rump freckled

with dark brown and grey, and with an interrupted line of darker brown

down the centre of each feather; two centre tail-feathers minutely and

coarsely freckled with very dark brown; the next on each side very dark

brown, crossed by irregular bands of freckled brownish grey and black;

the next on each side similar, but the bands narrower and less

conspicuous; the two outer ones on each side very dark brown for three

parts of the length, the apical portion being white, stained with

freckled buff and black on the outer webs; the basal or dark portion

crossed by narrow indistinct and irregular bars of deep buff; breast

freckled buff, grey and brown, some of the feathers in the centre of the

breast largely tipped with buff; abdomen and under tail-coverts deep

buff, crossed by narrow regular bands of dark brown; irides blackish

brown; bill black; feet and claws reddish brown.

The Plate represents a male and a female of the natural size.
