The Rise of Black WolfStreaming Video - 2010
In Yellowstone National Park, several wolf packs reside and compete for territory and pack leadership. A successful wolf pack survives by keeping order, respecting the hierarchy and obeying the leaders. But among these packs, a dark wolf with an unusual approach appears. Sometimes a loner, often a Casanova, eventually a leader - his surprising recipe for success broadens the definition of "normal" wolf behavior.
