I went to the local pond in search of mallard ducks or any duck species. Instead I captured this photo of a mute swan (cygnus olor) landing in the water with a wake behind him. Mute swans have heavy bodies and short legs. They are non-native in the US and can displace native species. They feed in underwater vegetation and have voracious appetites, eating up to 8 lbs of vegetation a day. They mate for life and can be very aggressive, displaying raised wings to ward off predators.
