We haven't had Mute Swans on the Lake in Central Park for several years. When the phragmites-infested strip known as Swan Island, once the favorite nesting ground for swans, was covered with black plastic and drastically altered as part of the Conservancy's much needed restoration plan, the resident swans took offense and off. [By the way, does anybody know the name of that particular rhetorical device, another example of which is He stood his ground and her up?]
Now there's another pair sailing around the Lake. Mute Swans, being an introduced species, are not beloved in the ornithology world. But they are beautiful and give the Lake a touch of class. That's my own opinion. I hope I'm not drummed out of the corps for uttering it.
