I had an argument with my brother on this subject when i read it in the bmg music trivia book, he sent me this link:

This is another one of those things that you always knew was utter bollocks - I mean why would a duck's quack not echo?

[decadnids]

have you heard a ducks quack echo?

[jamyna]

now im thinking i probably have heard it, but wouldn't actually be able to give a specific time / place, and after i read that it does not in such a seemingly well-informed book (sort of the musical equivalent of 'schotts miscellany') im inclined to agree it wouldn't echo.. that said, i daresay a recording of a quack would repeat its' arse off through my roland spacecho.. but that doesn't really count

I haven't heard a echoing quack, but I was walking past a lake once and could hear a sound that was a combination of hendrix wankery and a ringmod. Looked everywhere for a loudspeaker before it dawned on me that it was a duck.

Perhaps a fault one? Maybe feeding back on itself?

(Sorry, I'm on no sleep.)

dan - might have been a reed warbler / sedge warbler - they have pretty mental songs.

It does, they did an experiment on radio 4 the other year.
