Swans are not native to North America, but to Europe and Russia specifically. Think Swan Lake!

Here they were imported for their beauty, but in some places they can be destructive of underwater plants that native species prefer. The Canadian Geese are also getting to be a problem, numbers-wise in some places, and have extended their range further south than it traditionally existed. Swans, funny enough, have been brought in in some places to cut down on the number of Canadian Geese, as swans are monogamous and very territorial, unlike the geese who can hang about in ever-increasing flocks.

Paul is by far the most patient photographer ever, so gets better wildlife pictures! My camera batteries were dead, so I didn't take any that day!
