Question: The first bald eagle in history, Challenger, is trained to free fly into major sporting events during what national anthem of the United States of America
Context: Challenger is a non-releasable bald eagle in the care of the non-profit American Eagle Foundation.  He is the first bald eagle in history trained to free fly into major sporting events during the national anthem. "The Star-Spangled Banner" is the national anthem of the United States of America.  The lyrics come from "Defence of Fort M'Henry", a poem written on September 14, 1814, by the 35-year-old lawyer and amateur poet Francis Scott Key after witnessing the bombardment of Fort McHenry by British ships of the Royal Navy in Baltimore Harbor during the Battle of Baltimore in the War of 1812.  Key was inspired by the large American flag, the Star-Spangled Banner, flying triumphantly above the fort during the American victory.

Bald Eagle State Park is a 5900 acre Pennsylvania state park in Howard, Liberty, and Marion townships in Centre County, Pennsylvania in the United States.  The park includes the Foster Joseph Sayers Reservoir, formed by damming Bald Eagle Creek and other smaller streams and covering 1730 acre .

The Nittany Valley is an eroded anticlinal valley in the central portion of Centre County, Pennsylvania in the United States.  It is separated from the Bald Eagle Valley by Bald Eagle Mountain and from Penns Valley by Mount Nittany.  The valley is closed to the north by a high plateau that joins these two mountain ridges, but is open to the south at the southern terminus of Mount Nittany.  The valley drains to the Bald Eagle Creek through water gaps in Bald Eagle Mountain formed by Spring Creek, and Fishing Creek, along with smaller streams running through Curtain Gap and Howard Gap.  The Northwest side of the valley between the Bald Eagle Mountain ridge and the lower Sand Ridge is also known as the "Little Nittany Valley". The Bald and Golden Eagle Protection Act (16 U.S.C. 668-668d) is a United States federal statute that protects two species of eagle.  The bald eagle was chosen as a national emblem of the United States by the Continental Congress of 1782 and was given legal protection by the Bald Eagle Protection Act of 1940.  This act was expanded to include the golden eagle in 1962.  Since the original Act, the Bald and Golden Eagle Protection Act has been amended several times.  It currently prohibits anyone, without a permit issued by the Secretary of the Interior, from "taking" bald eagles. Taking is described to include their parts, nests, or eggs, molesting or disturbing the birds.  The Act provides criminal penalties for persons who "take, possess, sell, purchase, barter, offer to sell, purchase or barter, transport, export or import, at any time or any manner, any bald eagle ... [or any golden eagle], alive or dead, or any part, nest, or egg thereof." The coat of arms of Pennsylvania is an official emblem of the state, alongside the seal and state flag, and was adopted in 1778.  The flag of the Commonwealth of Pennsylvania consists of a blue field on which the state coat of arms is embroidered.  The Pennsylvania coat of arms features a shield crested by an American bald eagle, flanked by horses, and adorned with symbols of Pennsylvania's strengths—a ship carrying state commerce to all parts of the world; a clay-red plough, a symbol of Pennsylvania's rich natural resources; and three golden sheaves of wheat, representing fertile fields and Pennsylvania's wealth of human thought and action.  An olive branch and cornstalk cross limbs beneath—symbols of peace and prosperity.  The state motto, "Virtue, Liberty and Independence", appears festooned below.  Atop the coat of arms is a bald eagle, representing Pennsylvania's loyalty to the United States.
