American
Woodcock
Male woodcocks use flight displays to establish
and maintain territories and court females.
Displays are most common during spring mornings
when males perform in small clearings for 50 to
60 minutes, and during evenings for 30 to 40
minutes. The male begins his display on the
ground, where he produces nighthawk-like peent
notes about once every 10 to 20 seconds. After
launching himself into the air, he begins to fly
in a wide circle, wings twittering, until he has
climbed 200 to 300 feet in the air. The
twittering stops at the zenith of his flight,
when he begins singing a series of varied
chirping notes. He continues the song as he
descends in an erratic zigzag flight to the
ground, often landing close to the spot where he
started. He then resumes the peent
calls. Chases between rival males are common in
the small clearings where males usually display.
If a male succeeds in attracting a female, he
approaches her with wings held aloft; then the
pair may mate. Males are promiscuous, mating with
more than one female and taking no interest in
care of the young.
American Woodcocks build their nests on the
ground in open woods or brushy fields. The female
usually lays four spotted, blotched, pale buff
eggs in a scraped-out hollow lined with dead
leaves and other plant material. While
incubating, the female often remains on the nest,
even when closely approached. She leads her young
from the nest soon after hatching. Within a
couple of days, the young begin to feed in the
manner of adults. They can fly weakly at about
two weeks of age. Although they are fully grown
when 25 days old, they stay with their mother for
six to eight weeks.
The woodcock diet is about 75 percent earthworms.
A woodcock finds worms by probing in soft mud
with its long sensitive bill. It forages for
insects in leaf litter and it may eat small
amounts of seeds when earthworms are scarce.
With the first hard frosts, southbound migration
begins. Woodcocks leave at dusk as flocks of a
few to 50 birds begin to fly at low altitudes
toward their winter homes in the southeast
coastal plain and along the Gulf Coast. Woodcocks
show a strong tendency to return to the same
sites in summer and winter. Northward migration
begins as early as February when birds move into
areas where the ground has thawed. Some males
begin displaying before they have reached their
breeding grounds. American Woodcocks breed from
southern Canada to the Gulf of Mexico and west to
the eastern edge of the Great Plains.

Woodcock Range Map
The American Woodcock has short, rounded wings
and tail, short legs, and very long tapered bill
stemming from a thick base. Sexes are similar,
although females tend to be a little larger. The
upperparts are clad in variegated black, brown
and gray; the breast and belly are uniformly pale
rusty, as are the wing linings. The large rounded
head has three broad dark crossbands separated by
narrow rufous bands. The large dark eyes are set
far to the rear and high on the head, giving
woodcocks good vision even when probing in the
soil.
