Typical Environment
Occurs on the east slope of the Andes in Ecuador, Peru, and Bolivia. It inhabits humid foothill and lower montane forests, especially along edges, clearings with tall trees, and secondary growth. The species forages from the midstory to the canopy, frequently in mixed flocks. It tolerates some habitat disturbance where tall forest structure remains. Riparian forest corridors and montane foothill mosaics are also used.

A tiny Andean tyrant flycatcher, the red-billed tyrannulet is named for its distinctive reddish bill, which contrasts with its olive plumage. It often joins mixed-species flocks in foothill and lower montane forests, gleaning small insects from leaves and twigs. Its high, thin calls can be easy to overlook among louder forest birds.
Temperament
active and alert
Flight Pattern
short rapid wingbeats between perches
Social Behavior
Usually seen singly, in pairs, or family groups, and commonly joins mixed-species flocks in the canopy and edges. Likely maintains small territories during breeding. Nests are presumed cup-shaped and placed in foliage, with both parents participating in care. Courtship and pair bonds are typically monogamous.
Migratory Pattern
Resident
Song Description
Gives very thin, high-pitched tseet and tsi notes and short, sibilant phrases. The song is modest and can be easily masked by other forest sounds, but repeated notes reveal its presence in mixed flocks.
