Osiris – Egyptian Vulture
Hatched: Spring 1998
Osiris is the only Egyptian Vulture to be hatched by the World Bird Sanctuary. She was named after one of the oldest Egyptian gods, who was believed to be the god of life, death, and fertility. Osiris is a real trooper with a long list of credits. She has appeared at the Milwaukee County Zoo, Grants Farm, Roger Williams Zoo in Rhode Island, the Boston Zoo, World Bird Sanctuary, Busch Gardens in Virginia and the Tournament of Roses Parade in Pasadena. Osiris is very smart, a great flyer, learns quickly, and likes to chew on her leash.
In our programs Osiris demonstrates an amazing behavior developed by Egyptian Vultures in the wild. They use tools! Osiris demonstrates this remarkable accomplishment by picking up stones on the stage and dropping them on an Ostrich egg to crack it. How her species originally developed this behavior is not known, but the use of tools by any animal is considered a landmark accomplishment.
