I took a video of him pointing at some young (just left the nest a couple weeks ago) Mourning Doves in the yard. The only reason he broke off point - which you can't see in the video - is the pissed off Robin that is dive bombing both of us, as we're standing next to a tree with it's nest & chicks...

Here's the video: http://www.youtube.com/watch?v=ewuoK9y-Mnw
