ts are not sure how they follow the samecorridor year after year (Breen). There are three main theories of how a CanadaGoose navigates to the same breeding and wintering grounds each migration(Breen). One theory is that they rely on landscape cues, another theory is that theyuse the position of the sun and stars, and the third theory is that they have iron richtissue in their brains, like that of a pigeon and they use the earth's magnetic field tonavigate, but exactly how Canada Geese navigate is unknown (Breen). Someducks may fly as fast as eighty miles per hour but the Canada Goose flies at a muchmore graceful speed of forty-two to forty-five miles per hour during migration andcan fly as fast as sixty miles per hour. Canada Geese always take off into the windand usually fly at an altitude between one thousand and three thousand feet but inbad weather will fly as low as a couple hundred feet and when traveling over shortdistance they prefer walking because it uses less energy (Breen). When in flyingin flocks Canada Geese fly in their trademark "V" formation, this formation iscreated because each goose flies behind and to the side of the goose in front of it allows them to take advantage of the slipstream created, this technique is known toautomobile racers as drafting and it lets the Canada Goose fly seventy-one percentfurther than just going by itself (Breen). Another skill Canada Geese use to land inheavy wind is wiffeling, to do this the goose turns its body sideways so that it'swings are perpendicular to the ground, the bird loses it's left and basically falls outof the sky, this technique is known to glider pilots as side slipping because you slipout of the sky (Breen). Most people believe that the migration north and themigration south are the same but actually they are different (Breen). The migrationnorth to the breeding grounds is a slower and more relaxed one than that of the onemoving south (Wormer). The migration north some...
