Yellow Green Grosbeak Finch
A well-named grosbeak that is olive-greenish above and brighter yellow below, with a distinctive black face and a stout bill with a silver base. Disjunct range stretches from eastern Panama to southeast Brazil. Occurs in the subcanopy of lowland forest, up to around 1,000 m. Typically found in small groups, sometimes as a part of a larger mixed-species flock. Often draws attention to itself with piercing buzzy and squeaky calls. Not likely confused, but compare with female Red-and-black Grosbeak, which has entirely black head.
