Golden eagle nests are on average 5-6 feet wide and 2 feet high, these nests can weigh hundreds of pounds. The largest golden eagle nest ever recorded was 20 feet tall and 8.5 feet wide!

Bald Eagle

Haliaeetus leucocephalus

Eagles are at risk of being killed by canids because of their slow flight response when chased, larger size, and can be weighted down by recently eaten meat

Grizzly Bear

Ursus arctos horribilis

Grizzly Bears are 800 pounds, and live to be 25 years old out in the wild

Grizzly bears are the North American subspecies of brown bear

Some Grizzly Bears eat more than 40,000 moths a day

Usually 1.5 to 2 times larger than the Black Bear

The Lifetime home range of Grizzly Bears are 800–2,000 square miles if they are male, while 300–550 square miles if they are female

Grizzly Bears are categorized as a threatened species under the Endangered Species Act

Black Bear

Ursus americanus

A group of Black Bears is called a sleuth or a sloth

They weigh 200-600 pounds

Canada Lynx

Lynx canadensis

Canada Lynx are incredibly rare in Yellowstone but they were present from 1880-1980, although in 2007 a Lynx was photographed along the Gibbon River and another was observed in Indian Creek Campground in 2010

Lynx are usually limited to conifer forests above 7,700 feet where its primary prey, the snowshoe hare lives, although it is often too insufficient to support lynxes. This makes their habitat larger and farther north,

Gulo gulo their circumpolar distribution extends south to mountainous areas of the western United States, including the greater Yellowstone area

In 2006–2009 seven wolverines were documented in eastern Yellowstone

Wolverines are 38–47 inches long, and 13–31 pounds. They are opportunistic eaters, that eat burrowing rodents, birds, eggs, beavers, squirrels, marmots, mice, and vegetation, including whitebark pine nuts. in 2009 the first confirmed Wolverine in Colorado, M556, was documented in over 90 years.

American Badger

Taxidea taxus

American Badgers are 22–28 inches long, 13–25 pounds, and are adapted to digging. They eat ground squirrels, pocket gophers, and other small rodents but will also eat ground-nesting birds and their eggs.

Adults preyed on by mountain lions, bears, and wolves. While coyotes and eagles will prey on young.

Mule Deer

Odocoileus hemionus

The other name for mule deer is blacktail deer

Mule Deer are incredibly vunerable and winter and usually their population decreases drastically

They are known for the way they jump while running, also known as bounding gait, which allows them to move incredibly quickly

Wolf recovery in Yellowstone had a very little effect on the deer population both mule deer and white-tailed deer outside of the park are subject to state-regulated harvesting in the fall
