THE COCK-TAILED FLY-CATCHER.

The COCK-TAILED FLY-CATCHER (_Alectrurus tricolor_)--the other member of

this group which we have selected for description--is easily recognisable

by its short, stiff tail, in which sometimes the two exterior and

sometimes the centre feathers are of very peculiar appearance, owing

to the very irregular development of the web. The thick conical beak

terminates in a delicate hook, the legs are slender, the tarsi high, and

the toes long. The wings are of moderate size and pointed, the third

quill being longer than the rest; the first and second are much incised

and narrow towards the tip. The plumage is soft, composed of small

feathers, and the bristles on the cheek-stripes are unusually large. In

the male bird the inner web of the very broad centre tail-feathers is

much developed; the body is almost entirely black, the throat, belly, and

shoulders being white. The plumage of the female and young is yellowish

brown, except upon the throat, which is whitish, with various light

markings, and the centre tail-feathers are no broader than those at the

side; all have greyish brown eyes. The beak is of a dirty light brown,

and the feet dark brown. The length of the Cock-tailed Fly-catcher is

five and a half, and the tail about nine inches. The wing measures two

and a half, and the tail two inches.

These birds inhabit all the plains of South America, and, according

to Azara and D'Orbigny, perch throughout the entire day upon the high

grass, from whence they rise to catch the insects as they pass, and then

sink with outspread wings and tail to their former lurking-place; they

rarely fly to any distance, and often seem to move through the air in

a backward direction. We are without particulars concerning the mode of

breeding and nidification of this species.

The CATERPILLAR EATERS (_Campephagæ_) comprehend a number of birds

inhabiting the East Indies and contiguous islands, as also Africa and New

Holland. With their mode of life we are but little acquainted, beyond the

fact that they associate in small parties, and seek their food almost

exclusively amongst the foliage of trees and bushes. They consume great

numbers of insects and their larvæ, and some few eat berries.
