The creamy-bellied gnatcatcher is a species of bird in the family Polioptilidae. It is found in Argentina, Brazil, and Paraguay.
Region
Atlantic Forest of southeastern South America
Typical Environment
Occurs in the Atlantic Forest and associated semi-deciduous woodlands of southeastern Brazil, eastern Paraguay, and northeastern Argentina (e.g., Misiones). Prefers forest edges, secondary growth, riparian thickets, and vine-rich understory, but also enters more mature forest midstory. Readily uses regenerating habitats and fragments, though it is sensitive to heavy degradation. Often accompanies mixed-species foraging flocks through the understory and lower midstory.
Altitude Range
Sea level to 1200 m

Ease of Keeping
Beginner friendly: 1/5
A tiny, hyperactive insect-hunter of the Atlantic Forest, it often joins mixed-species flocks and forages by gleaning among leaves and twigs. Its long black-and-white tail and warm creamy underparts make it distinctive in shadowy understory. Habitat loss and fragmentation of the Atlantic Forest are its primary threats. It builds a small, neat cup nest bound with spider silk and camouflaged with lichens.

short rapid wingbeats
Social Behavior

Song Description
High, thin, sibilant phrases interspersed with rapid trills and buzzy notes. Calls include sharp chips and scolds while foraging, often delivered in quick sequences.
