Since there are no trees and almost no cliffs on
Banks Island, nests are built on the ground and
slopes making the birds very vulnerable to
predators. Unfortunately, the people in Sachs
Harbor have killed many of the wolves on
Banks Island making foxes much more
common. The foxes in turn prey on the birds,
eggs, and chicks.

A curious fact about many of Canada's National
Parks including Aulavik is that the indigenous
people are permitted to hunt in the park.
