Gray Wolf (Canis lupus)
The gray wolf (Canis lupus) is a top predator in Yellowstone National Park, playing a critical role in maintaining the balance of the ecosystem. Reintroduced to the park in 1995, wolves have helped control the populations of elk and other large herbivores, leading to the recovery of various plant and animal species. Their presence has had a profound impact on the park's ecology, demonstrating the importance of predator-prey dynamics.
Grizzly Bear (Ursus arctos horribilis)
The grizzly bear (Ursus arctos horribilis) is one of the most iconic animals in Yellowstone, known for its large size and distinctive hump on its shoulders. These bears are omnivores, feeding on a variety of foods including berries, fish, and small mammals. Grizzly bears are essential for nutrient cycling in the park as they help disperse seeds and carcasses.
American Bison (Bison bison)
The American bison (Bison bison) is the largest land mammal in North America and a key species in Yellowstone's grasslands. Bison graze on grasses and other vegetation, helping to maintain the health and diversity of the prairies. They are also culturally significant, symbolizing the wildlife heritage of the American West.
Elk (Cervus canadensis)
Elk (Cervus canadensis) are among the most commonly seen large mammals in Yellowstone, with large herds roaming the park. These herbivores graze on grasses and browse on shrubs and trees, influencing vegetation patterns and providing prey for predators like wolves and bears. Elk migrations and population dynamics are closely monitored to understand their impact on the ecosystem.
Bald Eagle (Haliaeetus leucocephalus)
The bald eagle (Haliaeetus leucocephalus) is a majestic bird of prey found near the lakes and rivers of Yellowstone. Known for its white head and tail feathers, the bald eagle feeds primarily on fish but will also hunt small mammals and carrion. As a symbol of wildlife conservation, the presence of bald eagles in Yellowstone reflects the health of the park's aquatic ecosystems.
Yellowstone Cutthroat Trout (Oncorhynchus clarkii bouvieri)
The Yellowstone cutthroat trout (Oncorhynchus clarkii bouvieri) is a native fish species vital to the park's aquatic ecosystems. These trout are an important food source for a variety of wildlife, including bears, birds, and other fish. Efforts to conserve and restore cutthroat trout populations are crucial for maintaining the ecological balance in Yellowstone's rivers and lakes.
American Pika (Ochotona princeps)
The American pika (Ochotona princeps) is a small, furry mammal that lives in the rocky talus slopes of Yellowstone's mountainous areas. Pikas are known for their high-pitched calls and their behavior of collecting and storing vegetation for winter. They are sensitive indicators of climate change, as they require cool, moist habitats to survive.
