Observations of Foraging Northern Fulmars (Fulmarus Glacialis) in the Canadian High Arctic
We summarize observations of foraging northern fulmars (Fulmarus glacialis) in the Barrow Strait-Lancaster Sound region of the Northwest Territories from June to September 1984-90 and in Admiralty Inlet, N.W.T., in July 1989. In each year, fulmars scavenged hunter-killed marine mammal remains in the...
