The JACANAS (_Parræ_) form a group of remarkable birds, occupying the warmer parts of both hemispheres, and characterised by their slender body, long thin beak, narrow pointed wings, short tail, composed of slender feathers (in one species the latter are much prolonged towards the centre), and the extraordinary length of their thin toes and claws. The heavy, beautifully-coloured plumage is alike in both sexes, but the young differ considerably in appearance from the parents. Most members of this group have a bare patch or excrescence on the brow, and a thorn-like appendage on the first wing-joint. These beautiful birds frequent marshy ground, on the borders of rivers and ponds, and obtain the seeds and aquatic insects--that form their principal means of subsistence--from amongst the aquatic plants, over the surface of which their long feet enable them to run with astonishing rapidity. The nest is made among reeds, and contains usually either three or four eggs. The cry of the Jacanas somewhat resembles a laugh, and is generally uttered just after they have alighted, or when they are about to take wing. If suddenly surprised they instantly give warning to their companions, and immediately fly away, the whole party following, with neck outstretched, and screaming loudly. THE CHILIAN JACANA. The CHILIAN JACANA (_Parra Jacana_) represents a division of the above group, having the slender wing armed with a spur, and composed of pointed feathers. The third quill is longer than the rest. The delicate bill is bare at its corners, and has a skinny appendage at its base; the feet are long and thin, and have the claws and toes of nearly equal length. The short tail, formed of ten soft, slightly-pointed feathers, is rounded at its extremity. In the adult of this species the head, neck, breast, and belly are black, and the back, wings, and sides of the belly reddish brown. The quills are yellowish green, tipped with black, and the tail dark reddish brown; the eye is pale yellow, the beak red, tipped with yellow; the bare patches on the brow and corners of the bill are blood-red, the feet grey, and the wing-spurs yellow. The young are yellowish white on the under side; the crown of the head and nape are black, and the back olive-brown. This species is from nine to ten inches long, the wing measures five inches and one-sixth, and the tail two inches. "A bird so well armed as the Chilian Jacana," says Molina, "cannot want for means of defence in case of necessity, and it of course fights with great courage and vigour everything that attempts to molest it. It is never seen in elevated places, and never perches upon trees, but lives wholly in the plains, and feeds upon insects and worms. It builds its nest in the grass, where it lays four coloured eggs, spotted with black, a little larger than those of a Partridge. It keeps in pairs, and the male and female are almost always together, but it is rarely seen in flocks.
