Canada geese breed in the spring. They make nests of branches, twigs, grass, and weeds, often on small islands in marshes or ponds. The female usually lays from four to six dull-white eggs. The young live with their parents for about a year after hatching and then begin to look for a mate. They keep the same mates for life. Family members often continue to live together, forming extended families of related geese. Canada geese eat marsh grasses and crop plants, especially corn, wheat, and other grains.

Since the mid-1950's, the overall population of Canada geese has increased greatly in North America. This increase has occurred largely because of a rise in the amount of acreage used for corn production and the establishment of numerous wildlife refuges. Today, many nonmigratory populations of Canada geese live year-round in suburban and rural areas of the northern half of the United States. These geese sometimes damage crops, and their droppings can be a nuisance.
