This is one of two bald eagles residing at the National Aviary in Pittsburgh, Pennsylvania. The bald eagle is the an endangered species and is also the national bird of the United States.

Pittsburgh is fortunate to have the National Aviary, as pointed out by Wikipedia:

"The National Aviary in Pittsburgh, Pennsylvania is America's only independent indoor nonprofit aviary. It is also America's largest aviary, and the only accorded honorary "National" status by the United States Congress.The Aviary is home to 600+ birds of more than 200 species, many of which are threatened or endangered in the wild. This is one of the most diverse collections in North America (exceeding, for example, the esteemed National Zoo in DC, and Niagara Falls Aviary).
As a result, the Aviary has many species that are rarely found in other zoos or aviaries, for example: the Bare-necked Fruitcrows, Paradise Tanagers, White-tailed Trogon, Scarlet-headed Blackbird, Yellow-throated Laughing Thrush, Blue-winged Mountain Tanager, Pompadour Cotinga, Blue-necked Tanager, and Lesser Green Broadbill."
