Anas Americanus lato rostro: The Blue-wing Shoveler.
This is somewhat less than a common Duck. The Eyes are yellow; the
upper part of the Wing is covered with pale blue Feathers, below
which is a Row of white Feathers, and below them a Row of green;
the rest of the lower part of the Wing is brown; all the other part
of the Body is of a mixed brown, not unlike in colour to the common
Wild Duck. This Bird does not altogether agree with that described
by Mr. Willoughby, p. 370. But if, as he observes, they change
their colours in Winter, it is possible this may be the Bird. However,
as their Bills are of the same form, and by which they may be distinguish'd
from all others of the Duck kind, I cannot describe it in better
Words than the above excellent Author.
It's Bill is three inches long, coal black (tho' this
is of a reddish brown, spotted with black) much broader toward the
tip than at the base, excavated like a Buckler, of a round circumference.
At the end it hath a small crooked Hook or Nail; each Mandible is
pectinated or toothed like a Comb, With Rays or thin Plates inserted
mutually one into another, when the Bill is shut. The Legs and Feet
I am not certain whether this was a Male or Female.
