Habitat

Canada geese can be found in agricultural fields and in marshes that occur in desert streams . They like to sun on bare shorelines , or on the edge of iced streams. This goose is very common around Farmington's parks, athletic fields, and golf courses . Many populations of geese have, in face , developed such a liking for urban environments that they have become a nuisance in cities in Minnesota, Michigan, Colorado and other places.[1]

Biology

Diet

The main foods eaten by the Canada Goose are plant materials - roots , seed, shoots , bulbs, grain, and berries . A large amount of grain is eaten during the winter. This species gathers food by taking items off the surface or near the surface of the water, "up-ending" (raising its tail end up while moving its head below the surface of the water to eat vegetation), or taking food items off of the ground .

The Canada goose forages on the ground in water for its food, which consists of grain, stems, spikerush, and rootstocks . They will also feed on mowed lawns.[1]

Reproduction

This handsome goose mates for life, at about two to three years old. They breed from March to July, with their peak nesting season the first week of April, and may nest in dense marshes, on islands, or tops of muskrat houses, and on elevated platforms. They may also nest on haystacks, in abandoned heron nests, on dikes , and ditch banks. A clutch is generally four to seven eggs , and incubation is about 25 to 30 days.[1]

The breeding season begins in late April. The nesting habitat is highly variable, but is usually near water. Nests are on the ground near the water's edge or on muskrat or other mounds within the water. The nest is constructed of plant material , moss, and sticks , and lined with finer material and down . The female lays 4-10 (usually 4-7) eggs that she incubates for 25-30 days. The young are precocial and remain with the adults until the next spring . They are cared for by the adults for approximately a month to two months after they hatch .

Breeding Habitat: Wetland-open water Clutch Size: 4-10 Length of Incubation: 25-30 days Days to Fledge : 40-73 Number of Broods: 1
