BALD EAGLES ON THE REFUGE

One bald eagle nest exists at the Rocky Mountain Arsenal NWR, Commerce City, Adams County, Colorado. The nest was initiated in 1996, but there were no reproductive efforts until 2002.

Fledging history:
2002: one eaglet
2003: two eaglets
2004: two eaglets
2005: one eaglet
2006: two eaglets
2007: two eaglets
2008: one eaglet
2009: one eaglet
TOTAL: 12 eaglets

The year-round pair that reside at the Refuge have a large home range but start preparing the nest for spring hatching sometime in the late fall.

The Refuge was established largely due to the discovery of a communal winter roost of bald eagles here in 1986. Wintering eagle populations have been lower than in the early 1990's, most likely due to climate changes that affect their migrartion habits. Refuge Eagle In Flight Eaglets In Nest 2004
