Never seen this before. It's on the same golf course as yesterday and raises all kinds of questions. What are they talking about, the whole city, Forest Park or just the golf course? Does the Audubon Society think there are places that are unimportant to bird conservation? (Under water, maybe? But then some birds catch fish.) Does the adjective "important" modify "bird" or "area"? (Think about it.)
Enquiring minds want to know.
