The forest elaenia (Myiopagis gaimardii) is a small passerine bird in the tyrant flycatcher family. It breeds from Panama through Colombia, Venezuela and the Guianas to Bolivia and Brazil. It also occurs on Trinidad. This species is found in forests and the edges of mangrove swamps. The nest is a shallow cup of roots, bark and grass built in a tree. The typical clutch is two cream-coloured eggs marked with rufous and lavender. M. g. trinitatis, the subspecies endemic to Trinidad, is larger and has duller upper parts than mainland forms.
