ID Keys: Yellow wash on throat and belly, obvious

The Yellow-bellied Flycatcher is one of the smallest of the
Empidonax flycatchers to migrate through the state. While most Empidonax
flycatchers are very difficult to identify, the Yellow-bellied is the only one
in the eastern U.S. with a yellow throat. It is normally found as a
migrant in eastern South Dakota, but the similar Cordilleran Flycatcher is
sometimes found in the extreme western part of the state. It can often be
lured closer to a birder's location as it responds to various "pishing"
or squeaking sounds.
