Scissor-tailed Flycatcher
Tyrannus forficatus
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.

Katanga Masked-Weaver
Ploceus katangae
This red-eyed masked-weaver has a plain olive-green back and pink-brown legs. The breeding male has a black face mask, with the black band on the forehead above the bill varying from broad in the south to narrow farther north. Female and juvenile are dull and inseparable from other masked-weavers. Pairs and colonies are localized residents of reedbeds, wetlands and adjacent woodland, in a narrow global range between northeastern Zambia and southeastern DRC. The breeding males of Katanga and Southern masked-weavers are very similar, but the former are smaller, have some saffron around the masks, and have darker green backs and rumps; breeding male Tanganyika and Lake Lufira Masked-Weavers have more burnt-orange around the face and underparts, and ranges do not overlap.

Bicolored Hawk
Astur bicolor
Widespread but uncommon forest hawk of tropical America. Adults are mostly gray, darker on crown and upperparts, with two pale tail bands and rufous thighs that are often hidden from view. Belly is tinged rufous and faintly barred in the southern part of its range. Immature looks remarkably like a forest-falcon, but note its yellow eye and lack of dark crescent on face. Overlaps with the similar Rufous-thighed Kite in parts of South America. Bicolored Hawk is larger, lacks a vertical stripe on the throat, usually stays inside forest, and almost never soars. Feeds mainly on birds and is generally quiet and elusive. Birds from central and southern Chile as well as adjacent parts of Argentina are now considered a separate species, Chilean Hawk.
