The Bolivian Tyrannulet is a very drab medium-sized tyrannulet of humid montane forests and adjacent second growth forests and clearings. The Bolivian Tyrannulet is often found foraging either solitarily or in mixed-species flocks searching for insects and small fruits. No information is available on its breeding biology and is an area wide open for future research. Despite its limited range, the Bolivian Tyrannulet's population is believed to be stable and consequently has not been placed on any threatened species lists.
