The Druid Peak wolf pack was released into Yellowstone National Park in 1996 as part of the park's Wolf Restoration Project. The pack's would eventually grow to a maximum of thirty-seven members at its peak in 2001. It is believed to be the biggest wolf pack in history. The first alpha pair were #38 and #39***. A roving young male, #31, joined the group from Chief Joseph Pack. The dominant male, (#38) was shot when the pack had wandered out of the park in 1997, and #40 assumed dominance after her mother (#39) left***. Wolf #21, who came from a rival pack, joined the group as the alpha male after successfully courting #40. Later, #40 was killed by her subordinate sister, #42, who was also referred to as the Cinderella wolf. #42 assumed the position of alpha female and took her sister's mate, #21, as her own. It was at this point that the pack grew rapidly, with three litters of pups being raised that year for a total of twenty-one pups, twenty of which had survived into adulthood. #42 and #21 led the pack as the alpha pair for many years until in 2004, when #42 was killed by a neighboring wolf pack. #21 died soon afterward at the age of 9, after curling up under a tree. #302, also known as "Casanova", then became the alpha male for a period of time. He was given the name Casanova because of his promiscuous lifestyle as a wolf, living on the outskirts of Druid territory and often trying to lure the female Druid wolves over. Then #480 joined the pack as alpha male, making Casanova a beta male.* #569 became the alpha female. In the winter of 2009-2010, the pack contracted mange, causing many of the wolves to die from border skirmishes or starvation. After #480 was chased off, the males who took over the pack did not stick around because the remaining females were too weak to bear pups.*  The alpha female, #569, had died the previous fall, and #480's body was later found near the Hellroaring drainage. The Druids were down to one wolf in 2010, a female, 690F, who was believed to be unable to last the winter. She was later shot in Butte, Montana sometime in May that year by a rancher after she attacked his cattle out of desperation. Many wolves in Yellowstone have Druid bloodline so they still live on as many wolves were chased out or left the pack including four female wolves and a male wolf who left to form a pack with a different alpha male.

April 1996: Five wolves #38 and #39, the alpha male and female, and female pups #40, #41, and #42 formed the Druids.

1996: During that first year in Yellowstone, a yearling male, #31, dispersed from the nearby Chief Joseph Pack and joined the group. Then the original alpha female #39 left the pack and her daughter, #40, took her place as the lead female.

1997: The subordinate females #41 and #42 gave birth to two litters, yet #40 did not have her own litter. Lone wolf #39 reunited with the pack briefly.

2001: 10 pups were born to the adult females, boosting the Druid pack's numbers up to 37 members. They became the largest wolf pack ever recorded.

2002: The Druids splinter into small groups. Three new pack were from; Agate Creek, Geode Creek, and Slough Creek packs, were created, each anchored by a former Druid female born at the same den in Lamar Valley in 1997. The Druids were left with 11 members by 2002’s end, including the matriarch, Cinderella, and the long-time alpha male, #21.

2003: #302 joined the Druids from Leopold Pack. He fathered all of the pups but Cinderella's. The pack now had 17 members. #302 was nicknamed Casanova.

2004: Cinderella died in a group encouter with a rival pack, and #21 was found dead in the summer.

Druids left the Lamar Valley. No pups survived this year. Their numbers were down to 4 members at the end of the year.

More Information/Contradicting Sources[]

*** There is conflicting information about female wolves #39 and #40. In BBC's Wolf Pack documentary, they do not mention #39, and actually claims that #40 was the mate of the original alpha male. Doug Smith, who is a park biologist and the leader of the Wolf Restoration project in Yellowstone National Park, stated in the documentary that "the first alpha female was wolf #40. She was very aggressive, and she ruled with an iron fist" (source: BBC's Wolf Pack documentary). However, according to the 1995-1996 Yellowstone Wolf Project Report (page 15), #39 was alpha female when the group was released. The report says that in August, #39 went on lengthy excursions to the north of the pack's territory. She eventually left for good, and the one of the yearling females, #40, became alpha female and possibly took #38 as her mate. #38 was later shot outside of the pack, and then (some time after) #21, a male from the rival Rose Creek pack, joined the Druid Peak pack and took the place of alpha male.
