Photographed last week at Seney National Wildlife Refuge on the Upper Peninsula of Michigan.
I was confused by the coloration on the Cranes at Seney but found this explanation on the web :
"During the spring and summer, the plumage of sandhill cranes in regions with iron-rich mud acquires a rusty brown hue, due to the bird’s habit of preening the reddish mud into the feathers. This artificial coloration is lost in the autumn when the feathers are molted."
This explanation was confirmed by one of the refuge biologists.
