The Scissor-tailed Flycatcher (Tyrannus forficatus), also known as the Texas bird-of-paradise and Swallow-tailed Flycatcher, is a long-tailed insectivorous (insect-eating) bird of the genus Tyrannus, whose members are collectively referred to as kingbirds. The kingbirds are a group of large insectivorous birds in the tyrant flycatcher (Tyrannidae) family. The scissor-tailed flycatcher is found in North and Central America. Adult birds have pale gray heads and upper parts, light underparts, salmon-pink flanks, and dark gray wings. Their extremely long, forked tails, which are black on top and white on the underside, are characteristic and unmistakable. At maturity, the bird may be up to 14.5 inches (37 cm) in length. Immature birds are duller in color and have shorter tails. A lot of these birds have been reported to be more than 40 cm.
They build a cup nest in isolated trees or shrubs, sometimes using artificial sites such as telephone poles near towns. The male performs a spectacular aerial display during courtship with his long tail forks streaming out behind him. Both parents feed the young. Like other kingbirds, they are very aggressive in defending their nest. Clutches contain three to six eggs.
In the summer, Scissor-tailed flycatchers feed mainly on insects (grasshoppers, robber-flies, and dragonflies), which they may catch by waiting on a perch and then flying out to catch them in flight (hawking). For additional food in the winter they will also eat some berries.
