Field Notes
Description:
Mute Swans are large, all-white swans that are recognized by an orange bill, which is black at the base. A prominent black knob is at the base of the bill. Another distinctive characteristic is a curved neck held in an S-shape, with the bill pointed downward while the bird is swimming. Individuals weigh an average of 25 pounds and have a wingspan of 7 to 8 feet. Male (cob) and female (pen) mute swans are essentially identical in appearance, except that the male is usually larger and has a more prominent knob on the forehead.
Habitat:
Mute swans are associated with both tidal and freshwater wetlands. They can be found in ponds, slow rivers, coastal bays, and inland lakes. Mostly herbivorous, swans have a voracious appetite for submerged aquatic vegetation.
