More than other goose species, the Canada Goose has a high tolerance for people. The habitat is right. Golf courses and the typical suburban housing development that includes a pond of some sort are ideal for the birds. For sleeping at night and loafing during the day, they prefer the combination of water and grassy areas with open sightlines between the two. In cities they are protected from predators.
Loose dogs are about their only concern.
People bring them food. Feeding the geese is an activity that many people find enjoyable. The green lawns in the areas described above are consumed with gusto by the geese also. The geese find other food in abundance within a short flight from town. Waste grain and new green wheat in farm fields nearby are consumed with relish by the birds on their daily foraging trips.
