Flycatchers, which are found only in America and chiefly in the tropics, are insect-eating birds, generally having a grayish colored plumage, sometimes adorned with a slight crest or a coronal mark of orange, red, or yellow. Only two of the species found in North America are gaudy in plumage, the Vermilion, and the Derby Flycatchers. They all have the habit of sitting erect on a dead twig, and watching for passing insects, which they catch on the wing.
