The Yellow-bellied Flycatcher (Empidonax flaviventris) is a small passerine bird, measuring about 5 inches in length and weighing around 0.3 ounces. The species has a relatively long bill and a short tail, with a greyish-olive back and wings, and a bright yellow belly that distinguishes it from other flycatchers. The wings also have two wingbars, a whitish one on the tips and a yellow one in the middle. The eyes are dark and the legs are pale.
The Yellow-bellied Flycatcher is a migratory bird that breeds in the boreal forests of Canada and the northeastern United States during the summer months, and then migrates to Central and South America during the winter. The species prefers to breed in coniferous or mixed forests, usually near water, and often nests on the ground or low in trees. During migration, the birds can be seen in a variety of habitats, including woodland edges, parks, and gardens.
In terms of behavior, the Yellow-bellied Flycatcher is a solitary bird that is often seen perched on a high branch or snag, from where it sallies forth to capture insects in mid-air. The species feeds primarily on small insects such as flies, beetles, and ants, which it catches using its bill. During the breeding season, the birds also eat small fruits and berries.
The Yellow-bellied Flycatcher is a relatively common species, with a population of around 30 million individuals. However, like many bird species, it is facing threats from habitat loss and fragmentation, as well as from climate change. Conservation efforts aimed at protecting the bird’s breeding and wintering habitats are important for ensuring the long-term survival of this species.

It is a migratory species that breeds in Canada and the northeastern United States and winters in Central and South America. The species feeds primarily on insects, and can be found in a variety of habitats during migration. Conservation efforts are necessary to ensure the survival of this species in the face of habitat loss and climate change.
