Thanks for the links. Very cool. Both nests were occupied this morning.
I often get my own wildlife shows in my back yard. Here are a couple recent pictured.
I believe the one is a cooper's hawk. It could be a sharp shin, but based on size of head and body shape, my first guess is cooper's. He or she is a frequent visitor to my deck. I have bird feeders out and he is looking for an easy meal. It comes to the deck because the birds hide in the shrubs and under the deck when alarmed. He was there again yesterday. I wish he would only take the English Sparrows but they are awfully quick.
I have reflective film on the slider so he couldn't see me but I could see him. That explains the cloudiness.
I opened the slider for the pictures of the fox. He was probably 200 yards away. Had used 8X optical zoom and some digital zoom. Not a bad picture considering I wasn't using a tripod. I rested the camera against the door.
He was hunting mice and that was really cool. The snow is very crusty and over a foot deep. He would zero in on a house under all that and then leap in the air and try to break through. First attempt that I observed, he simply bounced off the ice. Then a little bit later he located another one and jumped even higher in the air and busted through head first and came up with a mouse. Very entertaining.
