PGC is seeking the help of birders and other volunteers to assess the current osprey population to assess the nest distribution, substrate, types of water bodies, and other nest attributes of their nesting sites. The information will be used to update the Pennsylvania Natural Heritage Program database and enable us to better understand the status of this state-threatened species.
