The grey wren is a species of bird in the family Troglodytidae. It is endemic to the southwestern part of Amazonas state in Brazil. This small, poorly known wren somewhat resembles a house wren, but its upperparts are gray.
Region
Western Amazon Basin
Typical Environment
Occurs locally in the southwestern part of Brazil’s Amazonas state, where it inhabits dense thickets, edges of terra firme forest, campinarana (white-sand) woodlands, and river-island scrub. It favors tangled understory with viney growth and fallen woody debris. The species is generally near ground level to mid-understory, using cover to forage and avoid detection. It may persist in lightly disturbed secondary growth if sufficient understory structure remains.

The Grey Wren is a small, elusive wren endemic to the southwestern portion of Amazonas state in Brazil. It often keeps to dense undergrowth and can be overlooked due to its subdued gray upperparts and furtive behavior. Like many Neotropical wrens, pairs may engage in duets, producing a surprisingly rich and energetic song for such a small bird. Its resemblance to the House Wren can cause confusion, but the colder gray tones on the back are a helpful clue.
Temperament
secretive and active
Flight Pattern
short rapid wingbeats
Social Behavior
Usually found singly or in pairs, sometimes with dependent juveniles. Nests are presumed to be enclosed structures placed in cavities or dense vegetation, as typical for wrens. Pairs maintain small territories and may perform duet singing.
Migratory Pattern
Resident
Song Description
Loud, bright series of trills and rattling phrases delivered in quick succession. Calls are sharp chips; songs can be antiphonal when a pair duets, creating a fast, bubbly sequence.
