<i>Branta canadensis</i> Length: 30-43" <p> The most common of the Canada Geese subspecies, some people believe it has become a nuisance. One report I read, said that one Canada Goose can deposit a pound of poop a day. It is very common in the S.F. Bay Area and you can find them in most open fields, parks, etc. They like mowed open fields. </p> <p> Canada Geese eat green vegetation, grains and aquatic plants. </p>
