Site has answers to some of these questions.
For instance:
Do we know what happened to any of the chicks that were banded at the Duke's Farm nest?
The oldest of the three males from the 2009 nest (C-96) was identified while fishing in 2013 at the Conowingo Dam in Maryland. The smallest male from the 2009 nest (C-94) was observed nesting in Connecticut and has fathered at least four chicks as of 2015. Finally, another male that was banded at Duke Farms in 2014 (D-98) was found near Little Sebago Lake in Maine. Unfortunately, residents witnessed him being attacked by a nesting adult bald eagle and he was later found deceased.
