While I was out photographing the towhees, sparrows, juncos and finches around noon, a cooper’s hawk dropped by to see if he could grab some lunch. He sat on the fence watching the other birds, made an unsuccessful dive into a rose bush after a towhee, then flew back to the fence, landing with his back to me. He continued surveying the area by the rose bush where the birds had been scratching, when he suddenly turned and dived to the ground, but landed behind the power pole, so I couldn’t see if he caught anything. As I moved to see if I could get a photo of him on the ground, Guildenstern ran up and challenged the falcon and it flew off.
