The yellow-bellied flycatcher (Empidonax flaviventris) is a small insect-eating bird of the tyrant flycatcher family.
Adults have greenish upperparts and yellowish underparts (especially on the throat), with a dusky wash on the chest. They have a white or yellow eye ring that lacks the teardrop projection of Pacific-slope ( E. difficilis ) or cordilleran ( E. occidentalis ) flycatchers, white or yellowish wing bars that contrast strongly against the black wings, a broad, flat bill, and a relatively short tail when compared to other members of the genus. The upper mandible of the bill is dark, while the lower mandible is orange-pink. DNA testing in 2014 confirmed a field mark, involving the extent of buffy edging on the secondaries, to reliably distinguish this species from the two so-called "Western Flycatchers." [2] [3]
Measurements: [4]
Yellow-bellied flycatchers wait on a perch low or in the middle of a tree and fly out to catch insects in flight, sometimes hovering over foliage. They sometimes eat berries or seeds.
The yellow-bellied flycatcher's song can be transcribed as a rough, descending "tse-berk", which can be similar to the more common least flycatcher's snappier, more evenly pitched "che-bek."
Their breeding habitat is wet northern woods, especially spruce bogs, across Canada and the northeastern United States. They make a cup nest in sphagnum moss on or near the ground.
These birds migrate to southern Mexico and Central America.
