[3] was for several years [2010 - 2012] the dominant breeding female of the Lamar Canyon pack in Yellowstone National Park.Born in 2006 in the Agate Creek pack to Agate Creek Wolves #113M (born a Chief Joseph Wolf in 1997) and Wolf #472F (born a Druid Peak wolf in 2000), [4] [5] [6] she was principally known by the year of her birth.

Yellowstone wolf pack territories in 2011. Wolf population declines, when they occur, result from "intraspecific strife," food stress, mange, canine distemper, legal hunting of wolves in areas outside the park (for sport or for livestock protection) and in one case in 2009, lethal removal by park officials of a human-habituated wolf.

926F became a very popular subject for Yellowstone wolf watchers and photographers. [9] She was one of the stars of the “wolf-watching mecca” of Yellowstone [10] and was called “Queen of Wolves”. [11] In 2018, 926F ceded the role of alpha female to her daughter, who produced the first surviving pups in three years.
However, his nephew, Wolf #480M stepped up in that role shortly after. [2] [3] In 2006, only 4 wolves remained (302M, 480M, and two yearling females from the last litter of 21M). [4] [3] The dominant breeding female was collared as Wolf #529F and her sister, Wolf 569F was collared on the last day of 2006. [4] [3]
As of 2018, the global gray wolf population is estimated to be 200,000–250,000. [1] Once abundant over much of North America and Eurasia, the gray wolf inhabits a smaller portion of its former range because of widespread human encroachment and destruction of its habitat, and the resulting human-wolf encounters that sparked broad extirpation.
Northwestern wolves are one of the largest subspecies of wolves. In British Columbia, Canada, five adult females averaged 42.5 kg or 93.6 lbs with a range of 85 lbs to 100 lbs (38.6 - 45.4 kg) and ten adult males averaged 112.2 lbs or 51.7 kg with a range of 105 lbs to 135 lbs (47.6 - 61.2 kg), with a weight range for all adults of 38.6 kg to 61.2 kg (85 - 135 lbs).

In recent years, however, Yellowstone's elk population has plummeted. The Northern Herd, the only herd that winters in the park, has declined from nearly 20,000 animals in 1994 to less than 4,000 in 2013. Ecologists have linked this decline to a declining population of cutthroat trout in Yellowstone Lake, caused by invasive lake trout. With ...
