It breeds from Nicaragua south to northeastern Argentina and southeastern Brazil. It is the only member of the genus Capsiempis, but its taxonomy is uncertain, and it has been allocated to at least three other genera in the past.


This species is found in thickets, forest and streamside edges, dense second growth, and bushy pastures or clearings.


The cup nest is made of plant fibre and grass blades, decorated outside with moss. It is placed 2-7 m high in a tree, shrub, or maize plant. The typical clutch is two white eggs, usually umarked or with very light rufous speckles.

Feeding habits

Yellow Tyrannulets are active birds, seen in pairs or family groups feeding on insects, spiders and small berries. The prey is gleaned from foliage or taken in short sallies.


This species has a large range, with an estimated global extent of occurrence of 5,500,000 km
