Vermilion Flycatcher- Pyrocephalus rubinus- L:6 inches- The adult male Vermilion Flycatcher is very distinctive. The female and immatures are more nondescript but the streaking on the breast and pink tinge to the undertail coverts distinguish them from other flycatchers. The flycatcher family are so named because they catch most of their insect prey on the wing, in flight. They may sit perched for a long time, waiting for an insect to fly past, when they then fly out to catch it. There are over 365 species of flycatchers in the world.
