Hunters of the air
Yellowstone is home year-round to both golden eagles and bald eagles. These huge birds of prey are fast and agile in the air, hunting small mammals, waterfowl, fish (only bald eagles) and helping themselves to carrion.
Eagles pose little risk to healthy adult wolves but they could easily grab unguarded, young pups with their powerful feet and talons. Wolves can rarely catch cautious eagles.
The bald eagle is the national bird of the United States. They were previously endangered but were delisted in 2007.
