When I was playing Peregrine Falcon Naturalist last summer, we'd occasionally get a question like "If a Great Horned Owl and a Peregrine Falcon fought, who'd win?"
We may all find out together, because owls have nested in the nest box of a pair of falcons who aren't happy about it. Here's the story. Future updates would be linked on this page. And you can see photos of the nest box, which at this writing show the owl inside. The one in question is Oak Creek, first on the list.
