The COROYA (_Crotophaga major_) is about the size of a Jay, but more
slender, and possessed of a far stronger beak; the latter is longer than
the head, and slightly hooked at its extremity; the sides of the bill are
not so compressed as in other species; the feathers on the head and nape
are very long and pointed, while those on the breast are very broad. The
plumage is of a deep steel-blue, shading into violet on the tail and on
the breast. The eye is bright light green, its iris surrounded by a narrow
circle of yellow; the beak and bare skin about the eye are black, and the
feet blackish brown. This species is eighteen inches and two-thirds long,
and twenty-two inches and a quarter broad; the wing measures seven inches
and two-thirds, and the tail nine inches and five-sixths. The female is
not quite so large.
