Every Spring Northern Saw-whet Owls migrate up the north-east coast of the US and into Canada. Along the migration path is one of the Great Lakes, Lake Ontario. It's a long way across the lake so these tiny owls will stop on the southern shore of the Lake to rest before crossing. They are very small birds and are prey for larger birds of prey. Because of this they try not to move during daylight hours. They find a secluded spot and sleep. When a hiker encounters a sleeping Saw-whet they typical don't fly off. But they can look annoyed when they are awakened.
