G n o Abstract: We review the distribution of the Buff-fronted Owl Aegolius harrisii harrisii in Peru, supported by unpublished museum records and new specimens and observations. Compared to previous published records, the distribution otes N distribution of A. harrisii in Peru is almost continuous, from the northwestern Andes to the eastern southern Andes, between 250and andelevation 2960 m.range The fornorthern the species Peruvian in Peru Andes are show expanded a dense significantly. distribution Basedof A. harrisii on all recordsrecords, compared we deduce to thatthe distribution the overall elsewhere in the Andes.

The Buff-fronted Owl Aegolius harrisii (Cassin, 1849) is to Schulenberg et al.
