Pale-bellied tyrant-manakin


The pale-bellied tyrant-manakin is a species of bird in the family Pipridae, the manakins. It is found in Brazil, Guyana, and possibly Bolivia.

Taxonomy and systematics

The sulphur-bellied tyrant-manakin was originally described in 1853 as Tyrannula pallescens, mistakenly placing it in the New World flycatcher family. It was later reassigned to genus Neopelma that was erected in 1860.
The pale-bellied tyrant-manakin is monotypic.

Description

The pale-bellied tyrant-manakin is about long and weighs. The sexes have the same plumage. Adults have a large bright yellow patch with dusky borders on the crown. The rest of their face, their upperparts, and their wings and tail are olive. Their throat is whitish with faint gray streaks, their breast pale olivaceous gray, and their belly pale creamy whitish. They have a grayish mauve iris, a brownish to grayish bill, and brownish to grayish legs and feet.

Distribution and habitat

The pale-bellied tyrant-manakin has a disjunct distribution. Its largest range is in Brazil from the Atlantic in Maranhão and southwest almost to Bolivia in Mato Grosso, then sweeping east to northern Minas Gerais and then northeast to the Atlantic in northern Bahia and Rio Grande do Norte. A small range is along the lower Amazon and Tapajós rivers in eastern Pará and Amapá. There are also confirmed reports in southern Guyana. One source places it in Suriname but the South American Classification Committee has no records in that country. Some sources place it in extreme northeastern Bolivia but the SACC has only unconfirmed records there.
The pale-bellied tyrant-manakin inhabits deciduous and gallery woodlands, where it favors areas with heavy growth of vines. In elevation it reaches.
