The lifespan in the wild of geese who survive to adulthood ranges from 10 to 24 years. The British longevity record is held by a specimen tagged as a nestling, which was observed alive at the University of York at the age of 31. Surviving extreme temperatures in the winters the geese prefer to stay in urban areas, rather than a green space as there is more heat in industrial areas.

"Distribution and Habitat"

Article Body
By the early 20th century, overhunting and loss of habitat in the late 19th and early 20th centuries 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. In 1964, the Northern Prairie Wildlife Research Center was built near Jamestown, North Dakota. Its first director, Harvey K. Nelson, talked Forrest Lee into leaving Minnesota to head the center's Canada goose production and restoration program. Forrest soon had 64 pens with 64 breeding pairs of screened, high-quality birds. The project involved private, state, and federal resources and relied on the expertise and cooperation of many individuals. By the end of 1981, more than 6,000 giant Canada geese had been released at 83 sites in 26 counties in North Dakota. 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 B. c. occidentalis, may still be declining.[cit

"Behavior:

Article Body
Like most geese, the Canada goose is naturally migratory with the wintering range being most of the United States. The calls overhead from large groups of Canada geese flying in a V-shaped formation signal the transitions into spring and autumn. In some areas, migration routes have changed due to changes in habitat and food sources. In mild climates from southwestern British Columbia to California to the Great Lakes, some of the population has become nonmigratory due to adequate winter food supply and a lack of former predators.[citation needed]

- Going to get rid of that sentence as citation is needed as well. Writer can not claim this about migration without citing a proper source to back it up.
