The
Buff-breasted Flycatcher is the smallest of the Empidonax flycatchers, and
one of the easier ones to identify. Their buffy breast distinguishes
them from other Empidonax species, although in some adult birds, the buffy
color isn't very apparent in worm plumage of the late summer. The
species has started to make a few appearances in southern Texas, in addition
to its normal U.S. range in far southern Arizona and New Mexico. The
species may have once been more widespread in the open pine forests of the
Southwest, before human beings arrived. They prefer pine forests with
an open grassy understory, a habitat that is maintained by regular fire.
With a human presence, natural fires are suppressed, changing the nature of
the understory.
Habitat: Found in open pine woodlands, often in
canyons with streams in the U.S. part of their range. Similar habitat
is used by the species during the winter and summer months, although they
will sometimes utilize lower-elevation habitats in the winter.
Diet: Feeds on insects and spiders.
Behavior: Forages by observing from a perch, and
flying out to capture insects in mid-air, or by hovering and gleaning
insects from the surface of the foliage or branches. They will also
sometimes drop down and grab insects from the ground.
Nesting: The nest of a Buff-breasted Flycatcher is
an open cup built of leaves, spider webs, grasses, and roots, with the
outside often covered with moss, lichen for bits of bark. The female
usually lays 3 or 4 eggs, and she alone incubates them. When the eggs
hatch, both parents help to feed the young. The young fledge after
about 16 days.
Song: Song of a Buff-breasted Flycatcher consists
of two similar musical phrases sung back-to-back...Pi-dew, pi-DEW.
Migration: Many populations are permanent
residents. Some short distance movements can occur for the winter,
with some populations moving to lower elevations for the winter.
Conservation Status: Populations appear to be
decreasing, but they are still found over a relatively wide geographic area
and are common in parts of their range.
The IUCN lists the
Buff-breasted Flycatcher as a species of "Least Concern".
