They have a white or yellow eye ring that lacks the teardrop projection of Pacific-slope flycatchers. The wingbars are white or yellowish, contrasting strongly against the black wings. They have a broad, flat bill and short tail. The upper mandible of the bill is dark, while the lower mandible is orange-pink.
Habitat and Distribution
Their breeding habitat is wet northern woods, especially spruce bogs, across Canada and the northeastern United States. These birds migrate to southern Mexico and Central America.
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 birds make a cup nest in sphagnum moss on or near the ground.
Calls and Songs
It has three primary call notes described as: a clear, ascending chu-wee, a sharp, gruff peekk, and a soft, descending pyu. The song is a rough descending TSE-berk.
