Black-capped Pygmy-tyrant
The Black-capped Pygmy-tyrant is one of the world's smallest passerines, a tiny tyrant flycatcher of Central and South American humid forests, with a conspicuous black cap, olive-green upperparts, and yellowish underparts. It inhabits the mid-story and canopy of lowland and foothill tropical forests from Costa Rica to Bolivia and Brazil. It feeds on tiny insects, gleaning them from fine foliage.
