Ушастая аруна Myiornis auricularis

Miniscule greenish-yellow flycatcher with a short tail that is easily overlooked in the lower levels of humid forests and second growth. Note the chestnut eye patch fringed by a black crescent (ear patch), its pale streaky gray neck, and yellow-olive back. The wings make a buzzing noise in flight. Listen for its repetitive “prrii-priii-prii” song and its “pic-pic-pic” call.
