Excerpts Adapted from the Birds of Saskatchewan:
"This champion traveler, graceful in flight and delicate in form, breeds around the Arctic Ocean to the northern tip of Greenland at almost 84° N, and as far south as Cape Cod, MA. It then enjoys a ?second summer' on its wintering ground-the edges of the pack ice around Antarctica? (Hatch 2002).
The species breeds in 2 very different areas: on the south shore of Lake Athabasca, where it nests in scattered pairs in the dunes, preferring stable gravelly plains to open sand; and in colonies on barren islands in lakes. Foraging and non-breeding birds frequent marshes, lakes, and rivers.
The Arctic Tern is a fairly common summer resident on the south shore of Lake Athabasca at Milton Lake and "possibly an uncommon breeder south to Wollaston Lake? (Smith 1996). Nero (1963a) estimated "that probably several hundred Arctic Terns were nesting in widespread fashion? across the Athabasca Sand Dunes. In 1973 it was found nesting at Bonokoski Lake (Renaud 1998). It is of casual (spring) or accidental (fall) status during migration in the rest of the province.
