Abstract: Ospreys breed regularly along the Arrow Lakes in the West Kootenay region of British Columbia. In recent decades almost all nests have been built along a B.C. Hydro transmission line. These nests have been monitored for over 20 years. The number of Ospreys present and their breeding success is highly variable from year to year. Thus far, attempts to determine the causes of this variation have been unsuccessful.

Key words: Arrow Lake, artificial nest sites, Osprey, Pandion haliaetus
