Serra do Mar Tyrant-Manakin

The Serra do Mar tyrant-manakin is 13 to 13.5 cm (5.1 to 5.3 in) long and weighs 13.5 to 14.9 g (0.48 to 0.53 oz). The sexes have the same plumage. Adults have a conspicuous yellow patch in the middle of the crown. The rest of their face, their upperparts, wings, and tail are olive-green. Their throat is dull grayish white, their upper breast grayish olive, and their lower breast and belly pale sulphur-yellow. They have a pale grayish mauve iris, a grayish bill, and grayish legs and feet.

The Serra do Mar tyrant-manakin is found in coastal southeastern Brazil from east-central Minas Gerais and Rio de Janeiro state south at least to far southern São Paulo state and possibly beyond into Paraná. It inhabits the Serra do Mar coastal forests, where it greatly favors the forest edge, dense secondary forest, and areas of stunted woody vegetation. It shuns the forest interior. In elevation it ranges between 1,150 and 1,800 m (3,800 and 5,900 ft).

The Serra do Mar tyrant-manakin feeds mostly on small fruits and also includes insects in its diet. It plucks or grabs its food from vegetation with a short sally from a perch; sometimes it briefly hovers.
