Monitoring thick-billed murre populations at colonies in northern Hudson Bay, 1972-92 / Anthony J. Gaston ... [et al.]. : CW69-1/80E-PDF
"Direct counts of Thick-billed Murres Uria lomvia present on study plots at Coats and East Digges islands, in the eastern Canadian Arctic, have been carried out since 1980, and photographic counts are available for Coats Island for 1972, 1984, and 1990. The Coats Island colony expanded in area between 1972 and 1984, and the population of the east subcolony doubled between 1972 and 1990; trends at the west subcolony were probably similar. Counts of the study plots suggest that this increase may have ceased about 1989"--Abstract.
