A tiny canopy flycatcher, the yellow-crowned tyrannulet is the sole species in the genus Tyrannulus. Its yellow crown patch is often concealed but can be flared when excited. It frequently flicks its tail and wings while foraging high in the canopy and at forest edges, where its thin, high-pitched calls carry surprisingly far.
Temperament
active and alert
Flight Pattern
short rapid wingbeats with quick sallies from perches
Social Behavior
Usually seen singly, in pairs, or small family groups. Frequently joins mixed-species flocks in the canopy and along forest edges. Nest is a small cup placed high in trees; both parents attend young.
Migratory Pattern
Resident
Song Description
Gives thin, high-pitched tseet and seee notes, often in quick sequences. The voice is penetrating but soft, repeated from exposed perches in the canopy, especially at dawn and late afternoon.
