WOODCOCK, common name for six
species of birds of the genus Scolopax, of
the family Scolopacidae.
Four species occur on
islands of eastern Asia and the East
Indies, and are little known. The other
two, as popular game birds, have been
extensively studied.
The American woodcock, S. minor, has
short, stout legs and averages about 28
cm (about 11 in) in length. The head is
relatively large with a long, straight bill, the upper section of which
can be flexed like
a finger. The dark, prominent eyes are set far back on the head. The woodcock
is
mostly brown, mottled with black, gray, and russet.
Native to eastern North America, the woodcock lives in wooded bottomlands,
where
the soft, moist earth yields its favorite food, the earthworm. The bird
remains hidden
by day, protected by its coloration.
During the mating season, the male chooses a protected nesting site, usually
near
a meadow, where it performs a spectacular courtship ritual, either in the
twilight or
before dawn. At the start, the woodcock struts about with drooping wings
and raised
tail and utters low, whining sounds punctuated by a single, nasal note.
Suddenly
darting off, it spirals upward from 30 to 90 m (100 to 300 ft) with much
twittering and
then dives swiftly downward. A characteristic whistling note heard during
the
descent is believed to be caused by the rush of air through the three narrowed
and
stiffened outer primary feathers. The nest, made of dried leaves and grass,
is built in
a depression on the ground. The female lays four spotted eggs in a clutch.
The Eurasian woodcock, S. rusticola, is larger, about 34 cm (about 13.5
in) long,
and is barred rather than plain on the underparts. It lacks the specialized
primary
feathers of the American species.
