American Robin Subspecies
It is the about the same size as or a little larger than main subspecies. It is lighter and is much more of a brownish-gray color. It has very little white on the tip of the outer tail feathers. Some 'T. m. propinquus' birds do not have any orange-red on the breast. This is probably more common in females. Males are usually darker. They may show light or whitish sides to the head.
