We live in the middle of our 40 acres of woods in Minnesota. Surrounding our 40 acres are more woods and wetlands. We hear owls all the time at dusk and during the night. We keep the window above our head cracked (during cold weather) or open (during hotter weather) just to hear the night sounds. We also have a sliding door in our bedroom that stays open at night from May to September, its almost like camping.
We don't see many owls, but we sure do hear them. As far as the owls go, we hear mainly Great Horned owls, Great Gray owls, Barred owls, and Saw-whet owls. Add to that, we often hear fox yapping, coyotes howling, snorting deer, grouse drumming, and an occasional howling gray wolf while we lay in bed at night.
