Birds
The BOBLINK, or RICE BIRD (_Dolichonyx oryzivorus_), possesses so
many features in common with both Finches and Starlings as to render
it difficult to decide amongst which it should really be placed. This
species is very numerous in North America, where it is much detested on
account of the serious damage it does to the fields of ripe grain. The
principal characteristic of the group of RICE EATERS to which this bird
belongs is their strong, conical beak, which is of moderate length, and
much compressed towards the sides, the upper mandible being narrower than
the lower portion, and lying, as it were, enclosed within its edges. The
body is compact, the head large, the wings of moderate size, the second
quill being longer than the rest; the tail is of great length, and each
individual feather composing it terminates in a sharp point; the feet are
not large, but powerful, and the plumage compact and glossy. The body of
the Boblink measures seven inches, its breadth being about eleven inches,
the wing three and a half, and the tail two and a half inches. The
plumage varies considerably at different seasons of the year. During the
period of incubation the male is black upon the head, the lower portion
of the body, and the tail; the nape is brownish yellow, and the feathers
upon the back black, with a broad yellow margin; the shoulders and rump
are of a yellowish white; the wing-covers and quills are black, bordered
with yellow. The eye is brown, the upper mandible dark brown, and the
lower one blueish grey; the feet are light blue. The female is smaller
than her mate, of a pale yellowish brown upon the back, the shafts of the
feathers being marked with a dark tinge; the lower parts of the body are
of a pale greyish yellow, the sides streaked in the same manner, as is
the back; the bridles are brown, and a yellow line passes over the eyes;
the quills and tail-feathers are much lighter than in the gala dress of
her mate. During the winter months the male bird wears a coat closely
resembling that of the female. The young are similar to the mother, but
all their tints are greyer and paler.
