Near me, in the middle of town, is a tiny city lake with a tiny island, on which egrets nest. They nest in some of the trees around the lake, too, to the great annoyance of the local businesses and others nearby. Although disturbing the egrets is illegal, many skirt the law.
The city fires off its public fireworks display at that lake.
Apparently some egrets were roosting near a couple transformers. The fireworks startled the egrets and some flew into the transformers, shorting the transformers out, plunging a 2 km diameter circle into darkness, including part of downtown.
Power will return about midnight if all goes well.
