So can anyone tell me what kind of creature makes a quick, fluty "woowoowoowoowoo"? (I could also describe the sound as shimmery and delicate, if you insist on getting fey about it.)
I've only ever heard this after dark in my backyard in the late spring/early summer. It sounds nice, and I think it's a bird or an insect, but I have no idea what it is. And you won't believe it, but plugging "woowoowoowoowoo" into a search engine is no help at all.
