On our trip years ago to the Lake Woodruff National Wildlife Refuge in DeLand Florida we were surprised to see a few Whooping Cranes flying and forging with the Sandhill Cranes. It was fun to see them interacting with the Sandhill Cranes. They were mostly far out in the fields but I managed to get a few images with them flying together in a flock.
