Mute Swans/ Canadian Geese
I have found out that these swans are housed when the water begins to freeze on the lake.
The Canadian Goose you see is one of about 25 that accompany the swans. In the past, the city has tried to scare away these geese due to an extreme amount of mess that they leave. loud noises(gun shots) only scared them away temporarily, they came right back.
There are also several pairs and single Mallard ducks also reside on the lake.
