A native of northern and central Eurasia, the Mute Swan was introduced into North America to grace the ponds of parks and estates. Escaped individuals have established breeding populations in several areas, where their aggressive behavior threatens native waterfowl.

Cool Facts
Downy young Mute Swans (called cygnets) come in two color morphs: a gray form and a white form. The gray (or "Royal") chicks start off with gray down and grow in gray-brown and white feathers, giving them a mottled look. White (or "Polish") chicks have all white down and juvenal feathers. Adults of the white morph may have pink or gray legs and feet instead of black, but otherwise the adults look alike.
The Mute Swan is reported to mate for life. However, changing of mates does occur infrequently, and swans will remate if their partner dies. If a male loses his mate and pairs with a young female, she joins him on his territory. If he mates with an older female, they go to hers. If a female loses her mate, she remates quickly and usually chooses a younger male.
The black knob at the base of the male Mute Swan's bill swells during the breeding season and becomes noticeably larger than the female's. The rest of the year the difference between the sexes is not obvious.
Very undecided about crop didn't have much to work with and frequently seems as tho i end up with negative space on the left side.. |
