Stresemann's bristlefront is a critically endangered species of bird in the family Rhinocryptidae, commonly known as tapaculos. It is endemic to Brazil, where there are 50 or fewer individuals living exclusively in the Mata do Passarinho Reserve.
Region
Atlantic Forest of eastern Brazil
Typical Environment
Occurs only in a tiny fragment of low to mid-elevation Atlantic Forest with very dense understory. It favors steep, shaded ravines, vine tangles, and bamboo thickets with deep leaf litter. The species keeps close to the ground and relies on intact forest floor structure for foraging and cover. Any further habitat degradation or fire poses an acute risk due to its extremely restricted range.
Altitude Range
100–800 m
Climate Zone
Tropical
Ease of Keeping
Beginner friendly: 1/5
Among the world’s rarest birds, Stresemann's bristlefront is confined to a single Atlantic Forest reserve on the Bahia–Minas Gerais border in Brazil. It was rediscovered after long periods without confirmed records and remains at immediate risk from habitat loss and fragmentation. The species is named for German ornithologist Erwin Stresemann and is notable for the stiff, whisker-like bristles at the base of its bill.
Temperament
skulking and highly secretive
Flight Pattern
short rapid wingbeats, low to the ground
Social Behavior
Usually seen singly or in pairs and strongly territorial within tiny home ranges. Nests are thought to be placed low in dense cover or earthen banks, with both sexes likely involved in care. The species spends most time on or near the forest floor, slipping through tangles and leaf litter.
Migratory Pattern
Resident
Song Description
Delivers a loud, clear series of whistles that can accelerate or rise in pitch, often given from hidden perches. Calls include sharp, penetrating notes used for contact and territorial advertisement.
