It was sixty degrees in Central Park today. The Great Horned Owl continued to be present and an Accipiter, either a Cooper's or Sharp-shinned Hawk was seen nearby.
After the fly out of the Owl, it cleaned its talons and then broke off a branch and chewed on it. This has happened on previous nights. I've looked for any mention of this behavior on the internet and haven't found anything that gives a clue about the reason for this interesting behavior.
