Bucephala clangula
The courtship display of the male Common Goldeneye is one of nature's most entertaining slapstick routines. In winter and spring, the male arches his large green head back until his bill points skyward; then he produces a seemingly painful peent. Completely unaffected by this chiropractic wonder, he repeatedly performs this ritual, often to rather disinterested females. Wintering Common Goldeneyes routinely remain in areas of open water across North America. At this time of year they tend to prefer the slow-flowing water of lakes, cooling ponds and reservoirs. Goldeneyes are frequently called 'whistlers,' because the wind whistles through their wings when they fly. |
