This robin-counting puzzle looks easy until you start noticing the tiny birds tucked throughout the spring garden.
Several large robins are sitting clearly on branches, a stump, and near the flowers, but smaller robins are hiding behind wings, inside the tree, near the fence, beneath larger birds, and inside the birdhouse.
Scan the picture slowly from top to bottom and count every robin only once. Some of the smallest faces blend surprisingly well into the scene.
Answer: There are 13 robins in the picture.
