How turkey vultures survive in the wild
Turkey vultures pick up a lot of bacteria on their feathers while feeding on dead carcasses of animals. One way they deal with this is to spread their wings in the morning sun so the ultraviolet radiation can kill some of that bacteria.
When vultures urinate, the acidic urine sprays down on their legs and feet (turning them white), killing bacteria the birds pick up while standing on dead carcasses.
Mother Nature — What a clever lady. /Gary
