Yellow-crowned Elaenia Myiopagis flavivertex

Small, inconspicuous bird of coastal swamps and seasonally inundated forests. Yellow crown is essentially impossible to see under most viewing conditions; note dull overall appearance, indistinct wing bars, and longish tail. Inhabits upper levels of tall forest; also occurs in abandoned plantations and other disturbed habitats, where it may be found closer to the ground. Feeds on insects and fruit. Most similar to Greenish Elaenia but has more prominent wing bars; Forest Elaenia is more clean-cut, with a stronger facial pattern and white crown patch. Explosive song is a decelerating cackle; it is distinctive once learned and usually the most reliable indicator of this species’s presence.
