Maps showing the winter distribution and relative abundance of 144 species of North American birds were prepared from counts made during the National Audubon Societys annual Christmas Bird Count. The species selected for mapping are members of those bird families that are considered the greater potential threat to low-level aircraft operations within the continental United States. The discussion accompanying the maps summarizes the potential hazard to aircraft of the various species with relation to concentration areas, time of year, time of day, and geographical features.
