Field notes

  • It is the only member of the genus Aegolius native to the Southern Hemisphere.
  • The species lacks ear tufts, giving it a distinctive smoothly rounded head profile.
  • Its facial disk features white 'eyebrows' and 'mustache' streaks that create a unique 'X' pattern against a dark face.
  • It is considered one of the least-studied owls in the Neotropics due to its secretive nature and nocturnal habits.
  • Juveniles possess a distinct plumage, being almost entirely cinnamon-buff with a dark facial mask, unlike the darker-backed adults.
Habitat
Montane cloud forests, humid evergreen forests, and subtropical woodland edges.
Range
Fragmented populations throughout South America, including the Andes and parts of Brazil, Uruguay, and Argentina.
