Tyrannidae

 

(tyrant flycatchers), a family of birds of the order Passeriformes. The length is 7.6–40 cm. The bill, which usually is flattened, has bristles at the base and, sometimes, a hook at the tip. The wings are short and broad, or they are elongated and pointed. The coloration is most commonly gray, brown, or greenish. Individuals with white, yellow, or red plumage are infrequently encountered.

There are 365 species of tyrant flycatchers, distributed in the Americas (except the extreme north) and on the Galápagos and Falkland islands. Many species are migratory. Most tyrant flycatchers are arboreal, although some species remain on the ground. The birds build various kinds of nests. Some nest in tree hollows, and others in holes in the ground. The nests may be open or closed; some are hanging. A clutch contains two to six eggs, which are incubated by the female for 12 to 19 days. The diet consists of insects and berries and, in some species, small vertebrates.
