Virginia Peregrine Falcon monitoring and management program: Year 2014 report
The Peregrine Falcon (Falco peregrinus) was believed to be extinct as a breeding species in Virginia by the mid-1960s. Intensive management efforts since the late 1970s have resulted in a known breeding population that has now exceeded 20 pairs. However, most known breeding pairs currently nest on a...

Fifty-six nesting structures were surveyed for Peregrine Falcon activity during the 2013 breeding season.

The reproductive rate was 2.0 chicks/occupied territory and 2.0 chicks/active territory. Nine falcons representing 18% of the chicks produced in the state were translocated from the coast to the mountains during the 2013 breeding season. This included 8 females and 1 male. All translocated chicks originated on bridges that have a history of poor fledging success. Birds collected from bridge territories were transported to Hogback Mountain in Shenandoah National Park and released in a hacking program.
