There really is a bird in the photo on the left. Look in the center of the photo and you will see a very well-camouflaged Brown Creeper. It disappears against the bark of a dark tree. In the photo on the right, you can see the bird more easily against the light-colored tree trunk. Brown Creepers feed by flying to the base of a large tree and working their way upward, sometimes spiraling around the trunk as they move higher. It is thought that by going up the tree they find insects and insect eggs hidden in the bark that are missed by other birds, like nuthatches, who work their way down a tree. Both of these photos were taken on Cook County Road 140.
