2013-05-24 I was suddenly disturbed by a dreadful racket being raised by the local crow, magpie and raven population in front of my building. Looking out the window I saw 2 pigeons sitting on the garage roof with the other birds flying about, screaming. Strange! Then I thought I saw something behind the beam supporting the end of the roof of the garage. So I took my camera and took a few photos the scene. Take a look at the thumb nail's arrow. Something's there, but what? Mystery! I then went out to look and eventually take some more photos and to try figuring out the mystery of the bird's behavior. Enjoy.
