The Canada Goose, though familiar to many people across the United States and Canada, is only a winter visitor to the northern fringe of the Neotropics in Mexico. The species commonly winters south along the Gulf of Mexico into Tamaulipas, as well as in central Mexican highlands and in limited numbers in northern Baja California. Though Canada Goose taxonomy is muddled and highly controversial, most of the birds wintering in Mexico appear to be composed of "Great Basin" Canada Goose (B. c. moffitti) and "Lesser" Canada Goose (B. c. parvipes). These birds are largely gray-brown, paler below than above, with black heads and necks highlighted by a large white cheek and throat patch. On the wintering grounds, these geese feed on grains and grasses and are often found mixed with other geese such as Greater White-fronted, Snow, Ross's, or Cackling Geese.
