Cooper's Hawk I looked up from my desk to see this immature bird sitting on the branch holding the peanut feeder. I quickly took two photos from within the room, about 6 feet inside the window, as my camera had 420mm of telephoto lens attached. Before I could take a third photo, much less remove the extension tube, it flew off.
Equipment: Canon EOS 7D, ES 300mm f/4L IS USM, 1.4x Extension Tube
