How can I teach a preschool class about Vultures?

I need some ideas for a unit on Vultures for my preschool class. I want them to learn as much as possible, even the gruesome details, but am having to get pretty creative with this. Helpful ideas might include demonstrations that can show how a Vulture locates food, lays eggs, urinates on it’s claws to clean them, digests carrion, projectile vomits, etc.
