Euler's Flycatcher Lathrotriccus euleri

Medium-sized flycatcher found in the understory and borders of humid forests. Note two conspicuous buffy wingbars framed with black and contrasting with a brown back, a gray-brown breast, and a buff belly. The lower mandible is paler than the upper. Similar to Fuscous Flycatcher, but without a prominent eyebrow. The song is a sharp “tjew-pew,” with more emphasis on the first note.
