The hook: this week the local news tells me that for a few weeks in the spring, the park seevice turns off the lights that illuminate the Gateway Arch.
(I almost wrote “the new lights that illuminate the Gateway Arch,” because they were installed “recently” in 2002 or something.)
Oddly, they have to turn off the lights because the Arch freaks out the migratory birds.
Sadly, the article doesn’t specify what the birds don’t like. They’ve seen metal, they’ve seen lights. I suppose it’s because the light points up, not down?

On further research, they’ve seen lights, but they don’t like them. We’re all supposed to lower the lights for the birds.
