This year marks 30 years since the reintroduction of Bald Eagles in Pennsylvania.
With the help of the Canadian government, several agencies brought bald eagle chicks back to their states to reintroduce Bald Eagles. The Hays bald eagle pair first started nesting along the Monongahela River in Pittsburgh in 2013.
A nest was observed by workers at the Keystone Iron and Metal Company.
The pair successfully hatched one eaglet but on June 6, 2013 a strong storm blew the nest down and the parents successfully fledged the eaglet on the ground.
Experts say it has probably been more than 250 years since Bald Eagles last nested along Pittsburghs three rivers.
As recently as the mid-1980s, there were just a few remaining nesting Bald Eagles pairs anywhere in Pennsylvania.
