_Food._--The woodcock is a voracious feeder; its principal food is
earthworms or angleworms, of which it has been known to eat more than
its own weight in 24 hours. It is said to feed mainly at night or during
the hours of twilight or dusk. The worms are obtained by probing in mud
or damp earth in any place where worms are to be found, including
gardens and cultivated fields. The long bill of the woodcock is well
supplied with sensitive nerves, in which the sense of touch is highly
developed; it can detect the movements of a worm in the soil and capture
it by probing. Numerous borings are often seen close together,
indicating that the bird does not always strike the worm at the first
stab. Probably its keen ears also help to locate its prey. It is said to
beat the soft ground with its feet or wings, which is supposed to
suggest the effect of pattering rain and draw the worms toward the
surface.
C. J. Maynard (1896) made the following observations on a captive bird:
The floor of its house was covered to the depth of four or five
inches with dark-colored loam, in which I planted a quantity of
weeds, beneath which the woodcock could hide. I would drop a number
of worms on this soil, which, as the bird was too shy to feed at
first, had ample time to bury themselves. At times, however, I was
able to watch the bird unseen by it; then the woodcock, which had
remained hidden in the corner behind the sheltering weeds, would
emerge cautiously and walk over the ground, slowly and
deliberately, pausing every instant or two as if listening
intently. Then he would stamp with one foot, giving several sharp,
quick blows, after which he would bow his head near the ground and
again listen. Then suddenly he would turn either to the right or
left or take a step or two forward, plunge his bill into the earth,
and draw out a worm, which he would swallow, then repeat this
performance until all the worms were eaten.
During dry spells, when the worms have returned to the subsoil, the
woodcock must seek other foods. It then resorts to the woods, where it
turns over the leaves in search of grubs, slugs, insects, and larvae. It
has even been known to eat grasshoppers. Mr. Rich (1907) says that in
early spring, before the alder covers are open, it feeds on ants.
Frederick S. Webster (1887) reports a singular case, where the crop of a
woodcock was crammed full of leaves of a common fern.
