stopped by one of my favorite beaver ponds today and flushed about 30 ducks. half of them had to fight to get airborne and even then they could only go about 50 yards away. when they landed they would continue wing flapping and swimming to get out of sight. very odd behavior for this time of year. to me they all looked and behaved like young Juvies or molters but this seems way too late in the game to for youngsters to still be working things out, and I know its not molting time so any Ideas?
