Hawks often visit my backyard during winter, but not in summer. The other day my husband saw one diving behind the back fence. So I went out and sat halfway hidden under the patio. For a while nothing happened.
Yet, a House Sparrow's warning call, chi, chi, chi, chi, went on. I sat still.... Then suddenly jumped out of the rhododendron bush was a Cooper's Hawk.
"No luck here."
And off he went to another location.
