Distribution and food habits of the birds along the southeastern Baffin Island coast / by T.G. Smith and M.O. Hammill. : Fs97-4/1573E-PDF

"In coastal areas along the Hall and Beekman Peninsulas, N.W.T., 1125 hours of observations were made from fixed observation points, during walks inland and from small boats in the periods March through October 1978 and 1979.

The Canada Goose present in the area appears to be Branta canadensis interior. One hundred forty-six stomach and crop contents of 15 species of birds were examined. Dominant food items for pelagic feeding birds such as Northern Fulmars Fulmarus glacialis and Black-legged Kittiwakes Rissa tridactyla were the pteropod Spiratella helicina and the squid Gonatus fabricii. The most common alcid Cepphus grylle, appears to feed mainly on pelagic fish larvae.
