Ponds and waterways are filling up with one of the smallest ducks found on our shores, the Buffleheads. A most striking of winter residents (and feisty, too), the male is sharply feathered in black and white, with iridescent purple and green head feathers. The Buffleheads will be here through the winter, with most departing in early spring.
The name Bufflehead is derived from the name Buffalo-head, and they are so named because of the male’s puffy-shaped head. Another common name for this diminutive diver is Butterball.
The male’s head feathers are shaded with a beautiful rainbow sheen, while the female is a much plainer sort.
