Range / Habitat: Year-round in humid forest of southern Mexico, including Yucatan, Central American and just barely into northwestern South America.
Field Notes: Small passerine, with pale yellow underparts, olive wings and back, grey head. Compared to similarly-sized passerines, large head with stubby tail. As with all greenlets, sexes are similar.
Personal Notes: We had previously seen, but not photographed, this bird in Costa Rica. We came across it again in Cancun, Mexico where Richard persevered in both the photo and the identification.
