"This revised edition is not an expanded version of the original, summarizing, for example, the dozens of studies that hve been made of the productivity of various subpopulations of the "Giant Canada Goose" since its rediscovery. Rather, the main objectives of this revised, slightly enlarged edition are to redefine the range of this race as it was originally understood and to correct earlier assumptions based on the literature as to racial identity of peripheral populations."--Page xvii.
