Whooping Cranes ? (Probably not)

I saw a bunch of different migrating birds this morning while driving in Arkansas.  I saw this flock, which I was convinced were endangered Whooping Cranes.  Whooping Cranes fly in small "families" not big flocks, so this many probably would not be Whooping Cranes.  More likely, they would be Wood Storks.  But, nonetheless, it was a nice sighting.  (And, they might still be Whooping Cranes - who knows, maybe it was a BIG family!)

These were some other flocks, but I know for sure they weren't cranes.
