LAVARIEGA, Mario C.; MARTIN REGALADO, Natalia; RODRIGUEZ PEREZ, Ciro e GOMEZ UGALDE, Rosa María. Report of the Northern Saw-whet Owl (Aegolius acadicus) in the mountains and valleys of western Oaxaca, Mexico. Huitzil [online]. 2011, vol.12, n.2, pp.48-52. ISSN 1870-7459.
We mist netted an adult of the Northern Saw-whet Owl (Aegolius acadicus) in San Pedro Totomachapam, municipality of Zimatlán de Álvarez, Oaxaca, in December 2010. A photograph documents the first record in the physiographic subprovince Mountains and Valleys of Western Oaxaca, which expands the species' know range by 60 km to the south. The continuous pine-oak forests in this region, known to be the main vegetation type of the habitat of the Northern Saw-whet Owl, suggests that this rare species may maintain populations farther south of the known distribution maps available in the literature.
