Koan I live on the Lake of 2 Mountains ( Quebec),where each spring and fall the Geese would land, collect,- for there flight south or north. I feel like i am flying with them, driving each fall down the eastern seabord in my "Surf Mobile", seeing them above me, flying in formation under a lot of noise (quack,quack), and in Spring, same picture ,I come back with them. In October, I can hear and see them from my window, when they are flying over my house and I call out to them to wait for me, I am coming too, just another (silly) goose. Oh Canada, eh?

Apparently, it is now known that both birds and insects navigate migratory flyways by following magnetic field patterns and directions. Experiments on butterflys where they were put in large rooms with magnetic cancellation by hemholtz showed their ability to orient, normally observed as emanating from some instinctive source and not influences by outside cues, was severely impaired. More advanced experiments where birds would be hooded with hemholtz arrangements that selectively cancel components of the field have not yet been tried. Small grains of magnetite in the bird's inner ear may help concentrate the field for some sort of glandular pick up. It is also known that the polarization of light is observed by birds allowing orientation with the sun on even cloudy days. Another avenue to investigate I believe is the observation of UV radiation wich may allow birds to see reflections and polarizations of sky and water reflected UV light that may assist orientation. It is known that flying predators track prey by urine trails that reflect UV light, and birds' plumage patterns are much more distinctive in UV. The long range migration over water of sea birds such as Gannets requires earth orientation by fields and sub-observational phenomena, given the featureless sea beneath the animal that can provide no obvious track. Man has much to learn from the selected adaptations of animal species. EC<:-}
