It's been 25 years since the Exxon Valdez ran aground off the coast of Alaska, spilling millions of gallons of oil into Prince William Sound.
The impact on wildlife was devastating. Cleanup crews poured into the nearby port town, also called Valdez, where an animal rescue center was set up.

This is Hungerford, a large female snowy owl. Last summer she was just a hatchling — a gray ball of fuzz in the middle of the Arctic tundra. In the fall, newly equipped with adult plumage, she flew thousands of miles south until she reached the coast of Maryland. And this winter, she became an important part of an unprecedented research project.
