As with the adult color pattern, there are some variation among the different subspecies. The darker subspecies goslings have a brownish olive or blunt yellow coloring while those of lighter subspecies are lighter and brighter in color. These colors fade as the gosling grows into the adult color pattern. All goslings have black or blue-gray bills and legs and become darker as juveniles and adults. When on land, Branta canadensis eat a variety of grasses including Bermuda grass, salt grass and wild barley.
Geese are able to grab a hold of each blade and pull it out with their bills by jerking their heads.
They also eat wheat, beans, rice, and corn. In the water, the birds stick their head and upper part of their body into the water leaving their tail and back end extending in the air. They stretch their neck out, under the water, and slide their bills across the bottom silt. They also eat a number of aquatic plants such as eel grass, sea lettuce and sago. Reproduction Females start laying eggs during the first weeks of March and continue as late as June in parts of the Arctic.
