The PEACOCK TROGON (_Trogon calurus_) has the central tail-feathers
of great length. The feathers of the head, throat, upper breast, and
wing-covers are of a bright, metallic green, and gleam with a copper-red
and violet lustre; the lower breast, belly, rump, and thighs are purplish
red; the inner side of the wings, the quills, and tail are black. The eye
is a dull, carmine-red, and the bare patch that surrounds it dark grey;
the beak is deep red, tipped and edged with yellow, and the foot brown
and yellow. The female resembles her mate, but is somewhat less bright in
hue. The length of this bird is fourteen inches and a quarter, and its
breadth twenty-two inches and a half. The wing measures seven inches and
a quarter, and the tail seven inches; the centre tail-feathers exceed the
rest by six inches and a half. Spix first discovered this bird at Rio
Negro.
