Hi all, I've certainly heard American Bittern produce isolated notes more often than not when I've heard them migrating at night, both in the field and in the lab from recordings; I'd hazard a guess to say that the single note call is more likely to be encountered . . . but this is really pure speculation, when it comes down to it, because I've not heard a tremendous number of bitterns in flight at night!
