Canada
Geese are a species that has adapted well to human presence, becoming a
common resident of city parks and water bodies. Canada geese do migrate, but
might be found wherever open water exists in the winter. There's a
huge disparity in size between the smallest and largest races of Canada
Geese. The smallest race, called the "Cackling Goose", isn't much
bigger than a duck.
Habitat: Lakes, ponds, larger wetlands, marshes, city parks and
ponds. Often feeds in farm fields, especially in winter.
Diet: Primarily plant material such as
grasses, aquatic plants, seeds, and berries. Can rely quite heavily on
waste grain during winter months. Also eats some insects, small fish,
and crustaceans.
Behavior: Forages both on land and on water.
In water, swims on the surface, submerging its head and neck to obtain food.
Walks on land while foraging, and has learned to use agricultural fields for
foraging.
Nesting: Late March through late May
Migration: Birds summering in Canada migrate
south, but populations in the U.S. may or may not migrate depending on local
circumstance. They will overwinter if open water is available.
Conservation Status: Widespread and very common.
Numbers of Canada Geese today are undoubtedly much higher than they were
prior to European settlement of North America, as they've adapted extremely
well to a human presence, learning to take advantage of agricultural fields,
and open water in winter as a result of human activity (near river reservoir
dams, urban parks, warm water discharge from power plants, etc.).
