The rufous-crowned greenlet is a small vireo-like songbird that forages methodically through foliage, often joining mixed-species flocks. It weaves a delicate cup-shaped nest suspended from forked twigs, a typical vireo trait. Its soft, whistled phrases can be hard to locate as the bird moves quietly in the mid to upper canopy.
