I’m wondering if another Turkey Vulture defecated on this bird.

I read some Turkey Vultures will defecate on their legs when they get too warm in the summer months. They call this urohidrosis, and it accomplishes two things: it cools the skin on the legs and it “sterilizes” the skin against bacteria because the pH is so acidic.

I was walking one of the Sequoyah National Wildlife Refuge service roads when I spotted this Turkey Vulture. I was hand-holding my camera and lens.
