ColinE,
Can a duck swim?

Interesting question terry!
Mine floats - and paddles.
I guess you have to clearly define the word swim.

Does a duck with only one leg swim in a circle?

The only sound that cannot produce an echo is a ducks quack.

Sorry Celadon,that is simply not true. A duck's quack does produce an echo.

It's true too!

Scientists have shown that the timing & sequence of sound frequencies emitted by a duck are such that the (slower) following sounds destructively interfere with the reflected (faster) sounds, thus causing silence.

Anyone who doubts it should travel at the earliest opportunity at their own expense to their nearest duck-inhabited, cliff-bound lake and hear - or, rather, not hear - for themselves.

Ducks also know this. They almost always quack twice as they they often don't hear their own first quack.

got duck tucked under arm and will head towards the nearest mountain range!

Good Luck Helena !

An interesting aside ...

Cricketers in the hilly north of England have known of this lack-of-echo phenomenon for ages and even coined the phrase 'owt for a duck.

Re the spat between Celadon/Terry/JimC as to whether a duck's quack has or has not an echo,I would like to suggest that you contact Sir Peter Viggers,MP,who will no doubt be able to assist in answering this burning question.
I believe he has now moved from his residence taking his duck house with him.

JimC (and anybody else who thinks ducks don't produce an echo).

Google "echo duck".
