While hanging my exhibit up at the Univeristy of Wisconsin Arboretum, two sandlhill cranes made a stop by the window to hang out for awhile. What interesting birds! I was able to get get a close-up of the feathers. A naturalist told me that the brown color is from mud that they put on their feathers. The mud works as camouflage, letting the cranes match the ground color of the area they are living in.
