Abstract

We report the expansion of the known range of the eared pygmy-tyrant Myiornis auricularis, which had not been previously recorded in the state of Sergipe, northeastern Brazil. The present records expand the known distribution of the species to the northeast, by at least 400 km from central Bahia to Sergipe, and approximately 700 km further northeast to Pernambuco. We discuss the possible existence of a new subspecies, or even a new species, due to the isolation of this population by major rivers.

Keywords: New records, digital databases, photographic database, vocalization database.
