Facts about this animal

The Canada goose has about 12 subspecies, which have minor differences regarding the colouration of the plumage, but vary considerably in size and weight, the largest being the giant Canada goose (Branta c. maxima) with a body-weight of 6.5 kg in males and 5.5 kg in females, and the smallest the Aleutian (Branta c. leucopareia) and cackling (Branta c. minima) Canada geese with body-weights of slightly below 2 kg.

Bill and feet are black. The plumage of the head and neck is black except for a white chin strap extending from the throat to behind the eyes. Depending of subspecies, there may be a white band around the lower neck. Upper parts of the body and wings are darker grey, the breast is somewhat lighter. Lower belly and vent are white, the rump is black and the tail is black with white coverts.

4 to 6 white or creamy-white eggs are laid in a nest usually located near water, which are incubated exclusively by the female for 24-28 days.

The Canada goose’s food includes pond plants, tubers, roots and algae, grasses, short reed grasses, berries, seed, crops like clover, alfalfa, wheat, rye, corn, barley, oats and grain left in fields after the harvest.

Did you know?
That these geese are also renowned for their V-shaped flight formation? The front position is rotated since flying in front consumes the most energy.

Why do zoos keep this animal

The Canada goose is kept for educational reasons, often in mixed exhibits for North American fauna together with ungulates, cranes and other waterfowl. Outside the breeding season it may be kept in walk-thru exhibits, allowing for close encounters with the public. It is this a good ambassador species for wetland conservation. In Europe it may also serve as a good example of an invasive species. In North America, and parts of Europe, many Canada geese seen in zoos are not birds "kept" by the zoo, but free-flying birds having chosen the zoo as their habitat.
