What is the best explanation for the reason why Canada Geese do not get stuck to the ice in the winter? Warm arterial blood entering the foot transfers its thermal energy back into the venous blood, which means Canada Geese keep their feet at roughly the same temperature as the surrounding ice or water. Canadian Geese are evil and the heat of their wrath melts the surrounding ice, so they are forever standing in warm water. Canadian Geese do not send warm blood into their legs or feet, therefore their feet are always the same temperature of the surrounding ice or water. Canadian Geese have very high metabolic rates in the winter. This generates enough thermal energy to keep their feet very warm. They also have the physiological adaptation of rubbery footpads, which do not stick to the ice.
