- Ein ... Vogel
Red-legged seriema (Cariama cristata). These birds live in grasslands, savanas and open forests of South America. They cannot really fly and mostly eat snakes, lizards, frogs, rodents and insects. - The ostriches!
The coat of arms of Leoben is an ostrich. Apparently, they were considered as the only animals being able to eat iron. And since this is a mining town... ostriches are the obvious choice.
