Sharpbill Oxyruncus cristatus

A unique species with a patchy distribution from Costa Rica to Brazil. True to its name, the bill is sharply pointed. Both sexes are olive-green above and whitish or pale yellowish below with bold dark spotting. The orange crown patch is difficult to see. Not well known, but seems to occur mostly in mature forest in foothills from around 700–1,700 m. Often follows mixed-species flocks. Can forage acrobatically or perch upright for longer periods. Most easily detected by its strange song, a long descending whistle.
