Notes: na = not available. Data for Canada goose are aggregate population totals for 13 separate populations that nest in North America. Data for snow goose are aggregate population totals for the greater snow goose, lesser snow goose, and Ross’ goose populations. The 1992/93 and 1994/95 surveys of the western tundra swan population were incomplete.
