Northern Saw-whet Owl (Aegolius acadicus) [XC287826]

Subspecies
Aegolius acadicus (Sibley and Monroe 1990, 1993) has been split into Saw-whet Owl (Aegolius acadicus) and Unspotted Saw-whet Owl (Aegolius ridgwayi) following AOU (1998). This treatment has always been followed by BirdLife.

Possibly forms superspecies with Unspotted Saw-whet Owl (Aegolius ridgwayi), although ranges appear to overlap in southern Mexico (with apparent hybridization). Perhaps conspecific with Unspotted Saw-whet Owl (Aegolius ridgwayi).

Proposed subspecies brodkorbi from Sierra Madre in Oaxaca based on a single juvenile specimen.

The following 2 subspecies are recognised:

  • acadicus (Gmelin, 1788)
  •   -  From southern Alaska south to southern USA, east to south-eastern Canada and northern Florida. Also highlands of Mexico from north-eastern Sonora to central Michoacán, eastern in central highlands to Puebla, Hidalgo and central Oaxaca, with isolated population in south-eastern Coahuila, south-western Nuevo León and northern San Luis Potosí.
  • brooksi (Fleming, JH, 1916)
  •   -  Queen Charlotte Is (British Columbia).
