(VA) (Loudoun Wildlife Conservancy) Birds of prey numbers increase dramatically each winter in the county as our resident birds are joined by many others. Join Loudoun Wildlife Conservancy to search for winter raptors. We will drive the back roads of Loudoun until dusk with frequent stops to find and identify the many hawks, hopefully an owl or two, and any other birds that overwinter here. Bring binoculars if you have them.
