I was getting ready to take Sophie to school when I noticed a bird on our backyard tree. He was quite large and looked like a hawk. Out came the A100 with my longest lens and I clicked away. This fellow was not worried at all, as I was about 10 feet away from him. I posted an image on the DPReview website with a call for an ID and received a response within minutes. It is a Cooper's Hawk.
