A pair of carrion crows were walking on the ice on West Park lake. I originally got the camera out because the one farther from the shore was occasionally slipping and sliding.
But as I began to take pictures, it stopped walking, and instead began to peck vigorously at the ice. I thought it had pecked its way through to the water below, and was eating something it had noticed at the ice / water interface. Looking at these pictures, I’m less sure. It was eating something. But that may have been some of the fragments of ice which its pecking had created, or perhaps a morsel which had been frozen into the ice.
