White-headed Sawwing

Medium-sized, fairly common chickenlike marsh bird found in meadows, ditches, riversides, marshes, as well as parks and farmlands in close proximity to humans; often seen foraging in the open. Adults are dark slaty above and white below, with a rusty patch under the tail. Juvenile similar but duller in color. Remarkably variable song is a series of hooting, grunting, or rasping notes or phrases, repeated monotonously, often from an exposed perch.

Large flycatcher with an extremely long, forked tail. Pale gray overall with darker wings and a salmon-colored wash on the belly. In flight, look for brighter salmon underwings. Juveniles are duller and shorter-tailed than adults, but still distinctive. Breeds in open country of Texas and neighboring states, where it is often seen on fenceposts and utility wires. Winters mainly on the Pacific coast of Mexico and Central America, where it sometimes gathers in large flocks. Might be confused with Fork-tailed Flycatcher in winter range, but note paler plumage with salmon underwings.

Uncommon flycatcher with a highly restricted range in northern Peru. It is known from white sand forest near Iquitos and from Andean foothills in the vicinity of the cities of Moyobamba and Tarapoto. Plumage is mostly yellowish-olive with a pale bill and eye and yellow fringes to the wing feathers. Very similar to Red-billed Tyrannulet, but usually shows an olive (not gray) crown; voice is a more reliable way to separate the two species. Listen for a high, piping whistle given alone or in pairs. Calls have a rasping quality in the lowland part of the range. Inhabits forest canopy.
