Sounding like squeaky wheels needing grease, about 50 squealing long-necked birds circled overhead before settling into the water just outside our decoys.
These birds looked like no other North American waterfowl. In flight, the gangly birds stretched out their elongated necks and dangled long legs behind them, looking more like an ibis than a duck. Their wings beat strong, but slow, more like geese than the frenzied flapping of other ducks. They also stand upright like geese and easily walk on land.
