This episode starts with a Nature Walk, featuring Who's That Bird, non-bird edition, possibly round 4. T-Bone's dog previous success has him well ahead, maybe. Warren plays the sound of a nonbird, and each of us has to guess what the nonbird looks like, what it's trying to communicate, and provide the collective term for it. We each take a guess, which is as non-illuminating as usual. However, the correct answer sets off a real flood of interest in the water economy of the animals in question. Trust me, this is weirder and more interesting than it sounds, provided it doesn't sound very interesting to you. If you have any experience with unconventional sources of water, send us an email to tell us about it ([email protected]).
