On a damp, dreary October morning, blue jays were flying around our yard, screaming and squawking their presence. After a few minutes, my husband found the reason for this behavior — an owl sitting in a hole in one of our apple trees.
We identified it as an Eastern Screech Owl (info in link, below) and he spent the day sitting in that opening, sometimes awake, sometimes looking asleep. If the blue jays came back, which they did frequently, he would go out of sight, into the back of the hole.
How fortunate to have nature come to you! I didn’t even have to eave the house to photograph this bit of nature. I might have frightened the own away if I had.
