The fawn-breasted wren is a duet-singing wren of South America's lowland woodlands, often heard before it is seen. Pairs maintain territories year-round and communicate with coordinated antiphonal songs. It forages close to the ground in dense thickets, making brief, mouse-like dashes through cover.
Temperament
solitary and territorial in pairs
Flight Pattern
short rapid wingbeats with low, direct flights between cover
Social Behavior
Typically found in pairs that defend small territories year-round. Pairs engage in antiphonal duets and remain close while foraging in dense understory. Nests are domed or globular structures placed low in thick vegetation.
Migratory Pattern
Resident
Song Description
Loud, musical duets of clear whistles and chattering phrases, delivered alternately by the pair to sound like a single bird. Calls include sharp chips and scolding rattles when alarmed.
