Striking and conspicuous large flycatcher of savannas, grasslands, and other open country with scattered bushes and trees. All ages have black head and pale gray back, no pink in plumage as in the similar migrant Scissor-tailed Flycatcher. Adult tail is very long with lyre-shaped ribbons; juvenile has shorter tail but still looks distinctive. Perches on fences, low bushes, and even on the ground; at times in small flocks. Flight strong and direct, with tail sweeping behind. Some populations in South America are highly migratory, occasionally turning up far outside their normal range.
