A black swan — a bird far from where it belonged — died on Lake Harriet last week. Probably because it was so beautiful.
Black swans live in Australia as wild birds. Here in the Midwest, they are curiosities and decoration. You can buy them like a holiday wreath or an inflatable Santa.
Someone somewhere had purchased this swan, but it either escaped or was set free.
The dead swan (or another of its exotic species) had spent much of the summer on river backwaters in Bloomington. It had been seen and noted by local birders.
But in mid-December, just as a wave of Arctic air approached, a black swan appeared on Lake Harriet.
For two days, the bird was seen swimming with a flock of mallards in a shrinking patch of open water.
Many birders saw it, and immediately understood the problem.
The species is said to be winter-hardy, but open water is essential. Swans, like loons, must run across open water to gain air speed.
