Peat Deposits and Thick-billed Murre Colonies in Hudson Strait and Northern Hudson Bay: Clues to Post-Glacial Colonization of the Area by Seabirds
ABSTRACT. Deposits of peat moss are found in association with several major seabird colonies in the area of Hudson Strait and northern Hudson Bay. Because such deposits are absent from similar ground away from seabird colonies, they seem to have developed as a result of manuring by the birds. Conseq...
