We had a view of a "rough wing" up close and personal. Little is mentioned in the literature on the reason for the "rough wing" on this species. Some think it may be used in courtship. The leading edge of the wing has serrations and the shape of these serrations determines the sex and age of the bird. How cool it is that?
Starting 30 April wind shifts promise for good movements. Follow the latest with Kenn Kaufman and BSBO http://cranecreekbirding.blogspot.com/ to see how migration unfolds along Ohio's Great Lake. Take time to enjoy the early season.
