Scientific name: Empidonax flaviventris
Although its yellow belly makes it somewhat distinctive, the Yellow-bellied Flycatcher is a member of the difficult to identify group of Empidonax flycatchers. Yellow-bellied Flycatchers are territorial in both the breeding season and in the winter, although winter territories are solitary in nature while breeding territories involve a pair.
Early naturalists, egg collectors, and modern ornithologists all share the view that Yellow-bellied Flycatchers are very adept at hiding their nests, making detailed studies of breeding behavior difficult. Many basic life history questions remain to be answered about this species.
