Thick-billed murres and black guillemots in the Barrow Strait area, N.W.T., during spring: distribution and habitat use
During the "spring" periods of 1974–1976, Uria lomvia and Cepphus grylle in the central Canadian Arctic were concentrated in the Barrow Strait area. Aerial surveys indicated that densities of both species were higher in interface habitats (i.e. along boundaries of land or ice and marine wa...
