 Eastern
Phoebe
Eastern Phoebes are among the earliest
spring migrants. Males begin singing their familiar song
and setting up territories immediately upon returning to
their breeding grounds. The singing decreases when
females arrive and nesting season begins. Males perform
an erratic flight display, circling and diving while
singing. Phoebes originally nested on shelves in rocky
ravines that are partially sheltered from above. Today,
they often nest in or around human habitations. Phoebes
may build their mud and grass nests inside or under the
eaves of barns and sheds; they favor the undersides of
bridges and culverts. They are a frequent cowbird host.
In addition to their easily recognized song, phoebes are
distinguished by their habit of slowly and incessantly
wagging their tail, often with a sideways motion. Like
other flycatchers, Eastern Phoebes feed mostly by
sallying off a perch to capture flying insects. Bees and
wasps make up a large portion of their diet, especially
in late summer. Unlike other flycatchers, however, plant
food in the form of berries and seeds are a significant
part-as much as 10 percent-of their diet, primarily
during winter.
Eastern Phoebes are among the hardiest of flycatchers.
Wintering population densities are highest where minimum
temperatures are greater than 40 degrees, but some linger
through mild winters as far north as southern New England
and southern Illinois. Population fluctuations have been
observed and attributed to winter mortality in severe
winters and to cowbird parasitism.

Phoebe Range Map
Description: Eastern Phoebes are
medium-sized flycatchers. They are brownish gray above,
darkest on the wings, tail, and head, and have dark
bills. Underparts are whitish with an olive wash on the
breast and flanks. They lack the eye rings and wing bars
of the Empidonax flycatchers; they are similar in
appearance to Eastern Wood Pewees (Contopus virens),
but they lack that species' wing bars and orangish lower
mandible.
In the briefly held juvenal plumage, the upperparts are
browner than the adults with cinnamon tips to the
feathers of the lower back, rump, and tail. The wings
show two yellowish white wing bars and the underparts are
yellowish white. In both juveniles and adults, a
premigration molt in August results in a plumage that is
pale yellow below and greenish above. These colors fade
by spring.
Around 1840, John James Audubon became America's first
bird bander, and the Eastern Phoebe became America's
first banded bird, after he "fixed a light silver
thread to the leg" of several nestlings. When he
returned to the area the following year, he located two
of the banded birds with their own nests, evidence for
his supposition that birds return to their natal home to
breed.
