This is the smallest diving duck in North America. They're a beautiful little duck, but I usually find them extremely camera shy and tough to photograph.
We have thousands of them on the Niagara River and nearby on Lake Erie, but the moment they see a human, they're gone.
The northern limit of the Bufflehead's breeding range is the same as the Northern Flicker, because Buffleheads usually nest in abandoned Flicker cavities.
Unlike other diving ducks, who require a long run to take off from the water, the compact Bufflehead takes off almost vertically.
