Braunscheitel-Olivtyrann Elaenia cristata

Medium-sized nondescript flycatcher that usually shows an erect crest without white markings. Very similar to others Elaenia species and is best identified by its song—a gravelly “jer-jéhjeh,” and its call—a soft “wee.” Also note its olive-green back, grayish breast, pale belly, and two wingbars. Inhabits open areas with scattered trees and savanna woodlands where it usually perches very upright on the top of shrubs or trees.
