The smallest owl that visits Central Park is the Northern Saw-whet Owl. It's about eight inches tall. A Saw-whet has been in the park for about a week. Today, it was in a perfect spot to watch until dusk. A small group of us were hoping for a fly out, but the owl jumped to the center of the bush it has been perching in rather than flying out. I was disappointed but also glad to see that the owl could out smart us.
