 Dusky
Flycatcher
The Dusky Flycatcher has a gray back with a slight olive
tinge, buffy breast, light throat and its belly is a very
pale yellow. It also has a narrow white eye ring, white
wing bars and a long tail. Its song is similar to that of
the Hammond's Flycatcher - a staccato series of chirps, se-lip,
churp, treep and its call is a sharp whit.
The Dusky and Hammond's flycatchers, very similar in
appearance and voice, are closely related and difficult
to distinguish. The populations were probably separated
when the ice fields of the North advanced and the forests
were divided into western and eastern refuges. When the
flycatchers returned to the newly forested northern half
of the continent, each had developed differing habitat
needs, allowing them to coexist without competing for
nesting sites and food. The Dusky usually nests in the
lower ranges of the forest, preferring chaparral, while
the Hammond's chooses higher levels of tall fir trees.
The Dusky Flycatcher forages low over shrubby vegetation
for flying insects. It builds its nest on upright or
pendant twigs or in crotches of low shrubs or trees in
relatively dry sites. It usually nests from 3 to 8 feet,
but up to 40 feet, above the ground in willow, alder,
aspen and other trees and shrubs.
The Dusky Flycatcher breeds from British Columbia and
western South Dakota south to southern California,
central Arizona and northern New Mexico. It winters south
of the U.S.-Mexico border. It prefers woodlands
containing tall trees and tall undergrowth, mountain
chaparral and open, brushy coniferous forests.
