Last week William & Mary’s Center for Conservation Biology (CCB) published news of Virginia’s peregrine falcons in 2014.
As in Pennsylvania, Virginia’s breeding peregrine population has climbed from zero in the early 1970s to a nest count that matches the pre-DDT days. But just as in Pennsylvania most peregrines don’t nest in the mountains anymore.
In the report Libby Mojica of CCB writes, “Virginia’s falcon population is predominantly on the coastal plain with 24 breeding pairs on the coast including 10 [man-made] peregrine towers, 1 ground nest, 8 bridges, 1 Coast Guard navigation tower, 2 fishing shacks, 1 power plant stack, and 1 high-rise building. The population in the western part of the state remains small with only 3 pairs nesting on rock cliffs.”
Because of strong winds fledgling mortality is high at Virginia’s peregrine bridges so each year CCB, in cooperation with VDOT, translocates some of the bridge fledglings to hack boxes in the Shenandoah Mountains. This gives the young peregrines a better chance at life and may even persuade a few to nest in the mountains.
“Hope,” who nests at the Tarentum Bridge, was one of those translocated birds. She hatched on the Benjamin Harrison Bridge in Hopewell, Virginia in 2008 and was hacked in the Shenandoahs but she didn’t stay there long. Instead she flew nearly 200 miles northwest to nest on a bridge over the Allegheny River. We’re happy to have her!
