The animal on the cover of Bad Data Handbook is Ross’s goose (Chen rossii or Anser rossii), a North American species that gets its name from Bernard R. Ross, a Hudson’s Bay Company factor at Fort Resolution in Canada’s Northwest Territories. Other names coined for this species are “galoot” and “scabby-nosed wavey,” by Northmen. There is debate about whether these geese belong in the “white” geese genus of Chen or the traditional “gray” goose genus of Anser. Their plumage is primarily white with black wing tips, reminiscent of the white-phase Snow Goose, but about 40% smaller in size.

No matter their technical genus, these birds breed in northern Canada and the central Arctic (primarily in the Queen Maud Gulf Migratory Bird Sanctuary), wintering far south in the southern United States, central California, and sometimes northern Mexico. In Western Europe, these birds are kept mostly in wildfowl collections, but escaped or feral birds are often encountered with other feral geese (Cananda Goose, Greylag Goose, Barnacle Goose).
