Mangrove Vireo
Vireo pallens
Despite the name, not found in mangroves in most of its range. Common in scrubby woodland, brushy fields, and thickets of Yucatan Peninsula. Also very local in mangroves along the Pacific coast. Best field marks are the white wingbars and the yellow patch between the eyes and bill; most birds are pale yellowish below, a few are paler and grayer overall. Birds in mangroves of Central America are often rather colorless, with very reduced yellow tones. Twanging song is a common sound in much of Yucatan Peninsula.

Silver-backed Butcherbird
Cracticus argenteus
Medium-sized ambush-hunter with a long gray bill with a dark, hooked tip. Black head and face with a white nape and chin. Upperparts very pale gray, with white rump, outer part of wings black, inner part of wings white, and black tail with white tip. Rollicking, chuckling song.
Brown Pelican
Pelecanus occidentalis
Large and conspicuous, gray-brown bird of saltwater habitats. Strictly coastal; rarely seen on inland lakes. Very long bill with pouch for scooping up fish. Forages mainly by diving on fish from above. Frequently cues into fishing activity looking for handouts. Often flies in long lines close to water's surface.
Whiskered Tern
Chlidonias hybrida
Small buoyant tern. Breeding adult has distinctive dark smoky gray body and contrasting white cheeks (can look like broad white "whiskers" in flight) underneath a black cap. Nonbreeding plumage pale silvery gray overall with a faded shadow of the cap; juvenile has dark-checkered back. Note rather stout bill (albeit thinner than Gull-billed Tern) and square tail; compare to Common, Roseate, and Arctic Terns. Feeds by picking from surface, not splash-diving like typical terns. Common around wetlands, lakes, and rivers.
