Gassy Goose Canadian Goose Tag

To fly the Atlantic Flyway. Head North in the Summer and South for the Winter. Take photo's of Gassy near pot holes along her travels.

Description: Both sexes of Canada geese have a black head and neck except for broad white cheek patches extending from the throat to the rear of the eye. The female of a breeding pair is often smaller. The breast, abdomen, and flanks range in coloring from a light gray to a dark chocolate brown, either blending into the black neck or being separated from it by a white collar. The back and scapulars are darker brown, the rump is blackish, and the tail is blackish brown with U-shaped white band on rump. The bill, legs, and feet are black. Most subspecies are uniformly large and pale and exhibit the characteristic "honking" call.

There are 7 recognized subspecies of Canada geese: Atlantic, Hudson Bay or Interior, Giant, Moffitt’s or Great Basin, Lesser, Dusky, and Vancouver. In general, the subspecies nesting farther north are smaller in size and darker in color to the west. The Giant Canada goose is the largest goose in the world, with some individuals weighing more than 20 pounds. They can also be long-lived, with a banded Giant Canada goose at 30 years and 4 months currently holding the longevity record for waterfowl. David Sibley has developed an informative webpage that can assist in subspecies identification for Canada geese. Also, the Oregon Department of Fish and Wildlife has a helpful field guide to identify Cackling and Canada geese.




Breeding: Canada geese nest across inland North America and in more southerly habitats than Cackling geese. Canada geese exhibit very strong family and pair bonds, and tend to return to their natal homes to nest. Female Canada geese lay a range of 2 to 8 eggs with an incubation period of 25-28 days.

Migrating and Wintering: Canada geese are herbivorous, feeding on grasses, sedges, waste grain, and berries. In coastal areas of North America, grain-producing agricultural lands adjacent to estuarine or salt-water marshes with bulrush and cordgrass provide ideal winter habitat. In the mid-continent United States, refuges with fresh-water marshes and abundant food crops attract Canada geese.

Population: In general, populations of Canada geese are currently more stable than in previous decades. Nearly extirpated in the early 1900s, Giant Canada goose populations have become problematic in some areas due to their elevated numbers. Mississippi Flyway Giant Canada goose population estimates have increased an average of 3% a year after 1998 until 2007, when the Mississippi Flyway Giant Canada goose population was estimated at 1.64 million birds, a 5% decrease from 2006. With resident Canada goose estimates now over 3 million nationwide, several states have established early Canada goose seasons that focus solely on reducing populations of resident Canada geese. In contrast, the Dusky Canada goose population remains at relatively low numbers, with 2007 breeding population counts estimated at 10,000 birds. Breeding population estimates in 2007 for Atlantic Canada geese were 1.38 million birds while the Hudson Bay population was estimated to be 966,500 birds. The remaining subspecies combined accounted for over 2.7 million additional geese in the 2007 flight.
