Amazon Basin
Typical Environment
Found along major white-water rivers of the western and central Amazon Basin, especially on river islands and newly formed floodplain edges. It favors early successional scrub, sandbars with scattered shrubs, and open riverine thickets. The species frequently occupies dynamic habitats created by seasonal flooding and sediment deposition. It occurs locally along rivers such as the Amazon, Madeira, Ucayali, and Purus where suitable low woody vegetation is present.

The lesser hornero is a small ovenbird that builds the classic domed, mud ‘oven’ nest on low branches or human structures near large rivers. It is closely related to the pale-legged hornero and shares parts of its range, but is smaller and favors dynamic river-island habitats. Pairs maintain territories year-round and often perform loud, coordinated duets. The species is monotypic, with no recognized subspecies.
Temperament
solitary and territorial
Flight Pattern
short rapid wingbeats; low, direct flights between perches
Social Behavior
Usually seen in pairs that defend small territories along river edges. Both sexes cooperate in building the mud ‘oven’ nest and in raising the young. Nests are placed on low branches or structures in open riverine settings.
Migratory Pattern
Resident
Song Description
Loud, ringing duet of accelerating notes, with male and female overlapping in a fast-paced rattle. Calls include sharp chips and trills used during territorial exchanges and pair contact.
