Great horned owls are common in our area - Platte River Valley in NE
We get to hear them call for a partner at night, and can catch a reply most of the time.
Have also seen Burrow Owls in our pasture one season.
Years ago - Most unusual was seeing a snowy owl in a field during the day in early to late spring. I always wondered if this sighting was ok, or if it had something wrong. Only saw it once.
