Tiny Tyrant-Manakin

The tiny tyrant-manakin is about 7 to 8 cm (2.8 to 3.1 in) long and weighs 6 to 8.5 g (0.21 to 0.30 oz). The sexes have almost the same plumage. Adult males have a mostly hidden yellow patch on the crown. The rest of their olive head and their upperparts, wings, and tail are dull olive. Their throat and breast are paler grayish olive and their belly pale yellow. They have a dark iris, a dark maxilla, a paler mandible, and grayish legs and feet. Females have less yellow on their crown than males but are otherwise alike.

The tiny tyrant-manakin is a bird of the northern Amazon Basin. It is found from northeastern and southeastern Bolívar in Venezuela east through the Guianas and Brazil north of the Amazon River from the Branco and Negro rivers to the Atlantic in Pará. It primarily inhabits the interior of humid terra firme forest. It seldom is found at the forest edge or in clearings. It is a bird of the lowlands, reaching only about 500 m (1,600 ft) in elevation.

The tiny tyrant-manakin feeds mostly on small fruits and also includes some small invertebrates in its diet. It usually forages up to the forest's mid-story. It has been observed gleaning food with a short sally from a perch, sometimes while briefly hovering.
