Stan’s Notes: An excellent diver and swimmer, typically seen in large flocks on open water. Not a duck, as it doesn’t have webbed feet, but instead has large lobed toes. When taking off, scrambles across the surface of water with wings flapping. Bobs head while swimming. Anchors its floating nest to plants. Huge flocks of up to 1,000 birds gather for migration. The unusual common name “Coot” is of unknown origin, but in Middle English, the word coote was used to describe various waterfowl–perhaps it stuck. Also called Mud Hen. A favorite food of Bald Eagles.
