Canada Goose

Branta canadensis

Description:

The black head and neck with white "chinstrap" distinguish the Canada Goose from all other goose species, with the exception of the Barnacle Goose, but the latter has a black breast, and also grey, rather than brownish, body plumage. There are seven subspecies of this bird, of varying sizes and plumage details, but all are recognizable as Canada Geese. Some of the smaller races can be hard to distinguish from the newly-separated Cackling Goose. This species is 76–110 centimeters (30–43 in) long with a 127–180 centimeters (50–71 in) wingspan. The male usually weighs 3.2–6.5 kilograms (7.1–14 lb), and can be very aggressive in defending territory. The female looks virtually identical but is slightly lighter at 2.5–5.5 kilograms (5.5–12 lb), generally 10% smaller than its male counterpart, and has a different honk. An exceptionally large male of the race B. c. maxima, the "giant Canada goose" (which rarely exceed 8 kilograms (18 lb)), weighed 10.9 kilograms (24 lb) and had a wingspan of 2.24 meters (7.3 ft). This specimen is the largest wild goose ever recorded of any species. The life span in the wild of geese that survive to adulthood ranges 10–24 years.

Habitat:

This species is native to North America. It breeds in Canada and the northern United States in a variety of habitats. Its nest is usually located in an elevated area near water such as streams, lakes, ponds and sometimes on a beaver lodge. Its eggs are laid in a shallow depression lined with plant material and down. The Great Lakes region maintains a very large population of Canada Geese. By the early 20th century, over-hunting and loss of habitat in the late 19th century and early 20th century had resulted in a serious decline in the numbers of this bird in its native range. The Giant Canada Goose subspecies was believed to be extinct in the 1950s until, in 1962, a small flock was discovered wintering in Rochester, Minnesota, by Harold Hanson of the Illinois Natural History Survey. With improved game laws and habitat recreation and preservation programs, their populations have recovered in most of their range, although some local populations, especially of the subspecies occidentals, may still be declining. In recent years, Canada Geese populations in some areas have grown substantially, so much so that many consider them pests (for their droppings, the bacteria in their droppings, noise and confrontational behavior). This problem is partially due to the removal of natural predators and an abundance of safe, man-made bodies of water (such as on golf courses, public parks and beaches, and in planned communities). Contrary to its normal migration routine, large flocks of Canada Geese have established permanent residence in the Chesapeake Bay and in Virginia's James River regions, and in the Triangle area of North Carolina (Raleigh, Durham, Chapel Hill), and nearby Hillsborough. Some flocks in Canada may even choose not to migrate, even during the winter, if food (such as human leftovers) is constantly available throughout the season.
