remains of a robin's egg

Getting out of the car one day in the spring, there was a broken robin's egg on the driveway. So inside I went for my camera. The egg was among a twig and some leaves, even the gradations of gray concrete created neat patterns in the middle. We had at least one robin raising young in the area. They liked the berries on the oragan grape plant in my backyard. I had to fish one baby out of the pond, he had ended up on one of the plants, when he got scared by the dog. He let me cup him between my two hands, and I placed him on the fence, where he flew off.
