Notice anything strange?
One the left is an adult chipping sparrow, and he/she is seen here feeding its "child," who is actually a changeling. It"s a cowbird. Mother cowbird secretly left an egg in the chipping sparrow's nest, the egg hatched, and the changeling pushed all of its nest mates out, leaving its new mom and dad to raise their gigantic baby as an only child. Parasitism in action!
