The U.S. Fish and Wildlife Service and the Arkansas Game and Fish Commission have launched a joint investigation into the fatal shooting of a female bald eagle. 

The eagle, which was believed to be tending to her nest at the time of her death, was discovered near Monticello, Ark., late last month, according to a statement from the Game and Fish Commission.

The agency said the eagle was transferred to Little Rock Zoo, where veterinary staff determined that the preliminary cause of death was a gunshot wound.

"A reward of up to $6,000 is being offered for information leading to the arrest and conviction of the person or persons responsible," the statement added. "Anyone with information involved in this case is encouraged to contact the AGFC’s Stop Poaching Hotline at 800-482-9262."

The bald eagle is the national symbol of the United States. In 2007, the bird was removed from the country's list of endangered and threatened species, CNN noted

But the Bald and Golden Eagle Protection Act, the Migratory Bird Treaty Act and the Lacey Act still include protections for the bird. The Migratory Bird Treaty Act says that an individual could face up to two years in prison and a $250,000 fine if they're found to have injured an eagle.
