 And most of them have adaptations to be able to deal with that kind of thing. And so there was this recent paper about whooping cranes that followed a bunch of GPS-collared birds along their migratory pathway, and they looked at their stopover sites. And so these are basically wet spots where they either spent the night or spent a day feeding and resting and doing the things that they needed to do along their migration. And they looked at use of cranes.
