Wolf researcher Werner Freund feeds Arctic wolves with meat with his mouth in an enclosure at Wolfspark Werner Freund, in Merzig in the German province of Saarland January 24, 2013. Freund, 79, a former German paratrooper, established the wolf sanctuary in 1972 and has raised more than 70 animals over the last 40 years. The wolves, acquired as cubs from zoos or animal parks, were mostly hand-reared. Spread over 25 acres, Wolfspark is currently home to 29 wolves forming six packs from European, Siberian, Canadian, Artic and Mongolian regions. Werner has to behave as the wolf alpha male of the pack to earn the other wolves respect and to be accepted. (Reuters/Lisi Niesner)
