The other day I saw a small bird harassing a larger one, climbing above it and then diving down. Against the bright blue sky I could not identify the birds. Was wondering how one would photograph it. Well, Jody Melanson has posted an awesome photograph on fredmiranda.com.
I think you should be able to see it without registering.
