Northern Pygmy-Owl

Glaucidium gnoma

Also known as Mountain Pygmy Owl

Northern pygmy-owls are pint-sized woodland raptors active mainly during dawn, dusk, and overcast days rather than deep night. They routinely tackle songbirds and rodents up to twice their own body weight, caching surplus kills on tree forks or inside tree hollows for cold-weather meals. Pairs announce territories with steady, hollow toots that frequently trigger furious mobbing displays from chickadees, warblers, and nuthatches.

Responsible observation
  • Listen for Mobbing: Locate small songbirds giving agitated alarm calls around a single tree to spot the owl.
  • Scan the Nape: Look for the pair of black, white-bordered spots on the back of the head that mimic eyes.
  • Check Open Perches: Search exposed snags or mid-canopy perches during overcast mornings when hunting peaks.
