Віреон мангровий 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.
