As a result of this collaboration between filmmakers and scientists, National Geographic cameras were able to capture extraordinary scenes of life in the Druid Peak pack. The pack tests the intruder for six hours. Their reaction could mean life or death to the lone wolf. Finally, the alpha female accepts the newcomer, and the Druids have a new alpha male. Also caught on film are the complex relationships within the pack and especially between the alpha female and her sister.
Wolves can be as gentle as they are fierce, especially when there are pups around the den.
Every member of the pack, male and female, looks after the young ones, playing with them while demonstrating invaluable hunting techniques. Biologist Doug Smith is clearly in favor of the reintroduction, which he believes will restore the park to its natural balance. Rancher Martin Davis isn t so sure. He has seen wolves around his cattle, and he s worried about protecting his herd. They are true survivors, and it s just amazing to watch them get through their first two years in Yellowstone.
