Canadian Geese are monogamous and mate with the same partner for life, only switching partners if the other dies. Geese generally fly at an average speed of 20-30 mph with a top speed of 60 mph! Most flying occurs below 500 feet, but during migration geese can climb up to 20,000 feet as their weight decreases allowing for a higher cruising altitude. The honking and V shaped formation that signifies the coming of autumn or spring is a function of efficiency. As in cycling, the person at the front breaks the wind creating a draft and easier pedaling or flying for those behind. The honking is a way to communicate and encourage the goose at the front who has the hardest job. For more fun facts about geese check out: Wormer, J.V. (1968). The World of the Canada Goose.
