Research in the Park
Park biologists monitor the reproductive success of golden eagles using two annual aerial surveys from a small helicopter. In late April, researchers look for an incubating eagle or eggs in a nest. In late July, they count the number of nestlings and successful pairs (pairs that raise at least one fledgling). Data from these two surveys is used to monitor nesting territory and reproductive success of golden eagles in Denali.
