Similar Species
White-fronted Tyrannulet differs in having a vocalization at lower pitch. These two may be separated only by elevation in norther Bolivia.
Distribution
South America: Eastern slope of Andes of eastern Bolivia and northern Argentina, well separated from a second population in eastern Paraguay and south-eastern Brazil.
Taxonomy
This is a monotypic species[1].
This species formerly included White-fronted Tyrannulet.
Habitat
Moist forest canopy and sometimes edges on lower mountain slopes, up to a maximum elevation of 1800 m asl.
Behaviour
Usually seen in or near canopy, often in mixed fouraging flocks. Mostly seen performing active movements. Food includes both insects and small berries.
Vocalisation
A "weet" note is given either singly or as part of a series. Early mornings, it is most often heard as a slow series (1 note per 1-2 seconds), at other times of the day is may be gives as a more compact series or as well separated single notes. However, this species seems silent a lot of the time.
