About the Eastern Screech-Owl#

The eastern screech owl or eastern screech-owl (Megascops asio) is a small owl that is relatively common in Eastern North America, from Mexico to Canada. This species is native to most wooded environments of its distribution, and more so than any other owl in its range, has adapted well to manmade development, although it frequently avoids detection due to its strictly nocturnal habits.

Field-craft tips#

  • Never bait or call owls excessively; stay on trails.
  • A long lens (500 mm+) keeps a respectful distance.
  • Mostly crepuscular: lean on a fast lens, high ISO and stabilisation; keep distance and avoid flash at nests.
  • Sightings peak in May, which is when you'll have the most chances.

Ethics#

  • The welfare of the animal comes first: if it changes its behaviour because of you, you are too close.
  • Stay on trails, respect closures around nests, leks, dens and haul-outs.
  • Avoid playback and baiting in sensitive seasons; never bait predators.
  • Don't share precise locations of rare, nesting or roosting animals publicly.
