MULSANT'S WOOD-STAR.
MULSANT'S WOOD-STAR (Calothorax Mulsanti) is a very beautiful species of Humming Bird, inhabiting Columbia and Bolivia; the male is dark green on the back and sides, with a brilliant gloss; the chin, cheek-stripes, lower part of throat, a streak on the centre of the breast and the belly are white, the chin relieved by a violet sheen. The back of the female is lighter than that of her mate, her under side is white, and the lower tail-covers of brownish red; a line on the sides of the throat is deep olive-green, and the tail light brown, tipped with black. The habitat of this species, according to Gould, is confined to the temperate regions of Columbia.
The ELVES (Lophornithes), a most magnificent group of Humming Birds, are recognisable by the remarkable tufts of feathers that adorn, sometimes the head, sometimes the tail of the males of different species. The awl-shaped beak is somewhat flattened at its base; the feet are usually small, the toes short, and the claws long. The plumage of the male is rich and much variegated, while that of the female is very plain.
The PLOVER-CRESTS (Cephalolepis) possess a delicate awl-shaped beak, scarcely equalling the head in length; the toes are short, and armed with long thin claws; the wings are short, the tail comparatively long, and composed of broad feathers. The feathers on the head of the male are prolonged into a crest.
DE LALAND'S PLOVER-CREST.
DE LALAND'S PLOVER-CREST (Cephalolepis Delalandii), a very beautiful species, inhabiting Brazil, is of a pale but very pure metallic green on the back and centre tail-feathers. The crest that adorns the head is bright, light green, becoming darker towards its apex; in old age this plume changes to a steel-blue; the under side is dark grey; a patch that commences at the throat, and covers the breast and centre of the belly, is bright blue; the quills are greyish brown, shaded with violet; the exterior tail-feathers are black, edged with white; the beak is black, and the foot blackish brown. The female and young are without the crest and the blue patch on the breast. The body of this species is three inches and a half long; the wing measures two inches, and the tail one inch. The crest of the male is one inch and two-thirds long.
This graceful species of Humming Bird was first discovered by M. Delaland, in the southern portion of Brazil. Mr. Reeves states that it inhabits Rio de Janeiro, Minos Gerves, and Santa Catherina, but he was unaware whether it remains in those provinces all the year or not. "Of the two nests that I possess," says Mr. Gould, "one is of much more lengthened form than the other, but both are composed of the same materials, namely, fine fibrous roots, moss, lichens, and involucres of a composite plant, the whole matted together with spiders' webs of so fine a kind that they are almost imperceptible. Both had been suspended among the slender twigs of a species of banana."
