オリーブイカル Saltator similis

A grosbeaklike bird found in the canopy and borders of humid forests. woodlands, and adjacent clearings, where it can be fairly common when not persecuted for the wild bird trade. Note the broad white eyebrow and black mustache contrasting with the dark gray face, giving it an angry look. Olive-green on the back with a white throat and light gray underparts. Similar to Buff-throated Saltator, but with a white (not buff) throat. The song is a series of soft whistles “chew-cho-chew-cho-chewee.”
