just a quick post. 
i have been out of town and apon my arrival my brother told me that he thought there was a cooper's hawk in a friends yard. he had been observing it for several days now and was quite sure. he, being a fairly new to the hobby, sparked an incredulous response from me. turns out, to the best of my knowledge, he was right on. in the devlopments on defief road inhabits several cooper's hawks in someone's backyard. i  stand more humbly than yesterday.
