Human disturbances of waterfowl: causes, effects, and management
C. E. Korschgen, R.B. Dahlgren
1992, Fish and Wildlife Leaflet 13.2.15
Human disturbances of waterfowl can be intentional or unintentional. They may result from overt or directed activities or may be ancillary to activities not initially thought to be of concern to birds. Some of these disturbances are manifested by alertness, fright (obvious or inapparent), flight, swimming, disablement, or death. Therefore,...
