The buff-banded tyrannulet is a species of bird in subfamily Elaeniinae of family Tyrannidae, the tyrant flycatchers. It is found in Argentina, Bolivia, and Peru.
Region
Andes Mountains
Typical Environment
Occurs along the eastern and central Andes of Peru, Bolivia, and northwestern Argentina, favoring humid montane (cloud) forests and their edges. It frequents forest borders, second-growth scrub, and semi-open patches with scattered trees. The species often uses mid to upper canopy strata but will drop to lower levels along edges and ravines. It tolerates moderate disturbance better than many cloud-forest specialists and may persist in Polylepis fragments and adjacent shrublands.
Altitude Range
1800–3500 m
Climate Zone
Highland
Ease of Keeping
Beginner friendly: 1/5
This small Andean flycatcher is named for the distinctive buff band across its wings, which helps separate it from similar tyrannulets. It is frequently found in mixed-species flocks, where its high, thin calls often give away its presence before it is seen. Like many tyrant flycatchers, it captures tiny insects by quick sallies and foliage-gleaning in the canopy. It is generally inconspicuous but locally common within suitable montane forests.
Temperament
active and wary
Flight Pattern
short rapid wingbeats with quick sallies
Social Behavior
Usually found singly, in pairs, or small family parties, and commonly joins mixed-species flocks in the canopy. Pairs defend small breeding territories during the nesting season. Nest is a small cup placed on a branch fork or suspended among dense foliage, with typically two eggs.
Migratory Pattern
Resident
Song Description
Gives thin, high-pitched tseet and tsee notes, often delivered in short series. Song can include a rapid, delicate trill or a descending sequence that carries through the canopy. Calls are sharp and contact-like when moving with mixed flocks.
