These Trumpeter Swans have spent the winter in Alaska .This picture was taken in March near their winter habitat. During March the sun sets later and the conditions are perfect for photographing . By mid April the Trumpeter swans that did not spend the winter will now be showing up in large numbers and they usually head further north to nest . They prefer the long summer nights for rearing Their young further North These particular two will raise their young locally and next fall the young will head south . I have seen Signets (immature swans)during the winter , but not in numbers in good numbers. . Most our wintering Trumpeter swans will be all white and almost always paired up . The largest flying waterfowl in North America make the best subjects to study and photograph .
