Gallinago wilsoni.
1890, Maine
Oct. 8, L. Umbagog; - Where the mud was softer the bill was thrust
in deeper but rarely to its base, excepting at one period when the
bird waded out into the water up to its belly and probed for a
several minutes immersing the entire bill as well as the head up
to the eyes at each thrust and sometimes plunging the whole head
under the surface. These deep thrusts were performed more slowly
and often with marked deliberation the bill at times being kept
in the mud for a full second or two, sometimes motionless, some-
times working slightly up and down or from side to side . When
boring in soft mud the bird usually inserted its bill with the
mandibles from I/8 to I/4 of an inch apart at the tip always
closing it at the completion of the thrust and sometimes, when it
held it in the mud for a little while, closing and opening it
several times in succession with a champing motion. It found an
abundance of food . In fact at every third or fourth thrust on
the average, it drew up something which it worked up quickly into
to the mouth and at once swallowed. Twice I saw distinctly a small
worm ( not an earthworm) about I/4 of an inch long wriggling
and wrapping itself about the end of the bird's bill but usually
I could make out nothing beyond the working motion of the bill and
the evident act of swallowing. I was quite at a loss to under-
stand how the object was transferred from the tip of the long bill
by which it was certainly seized, back to the mouth, for the bill
was never raised but was invariably held inclining decidedly down-
ward during the operation.
