Canada Geese of the Mississippi Flyway with Special Reference to an Illinois Flock	1950	154	.pdf	application/pdf	61832	2923	68	A brief review of the distribution and taxonomy of Canada goose populations in eastern North America is relevant to an understanding of the data later pres- ented concerning the Mississippi flyway population. The duration of fertility is probably not a factor limiting the productivity of Canada goose populations, as captives have been known to raise young at ages that far e.xceed the length of life of most individuals in the wild, few of which live longer than about 5 years (see section on Population Survival).	cache/inhs-184.pdf	txt/inhs-184.txt
