Hilton Pond Center for Piedmont Natural History is a non-profit conservation, research, and education organization in York SC in 1982. It is the most active year-round bird banding site in the Carolinas with nearly 57,000 birds banded in the past 30 years. Studies include all aspects of natural history from vegetational succession to small mammals to general Piedmont ecology. A primary study species is the Ruby-throated Hummingbird, Archilochus colubris, of which nearly 4,500 have been banded locally. Through Operation RubyThroat, the Center also leads citizen science expeditions to Central America for the only long-term in-depth study of RTHU within their wintering range. The Center is designated as an Important Bird Area (IBA) by Audubon and BirdLife International. Of note is "This Week at Hilton Pond," an on-going series of photo essays about all aspects of natural history; published on-line, the installments are archived as a rich source of information for students, teachers, scientists, and the general public.
