what every partridge knows..

is that when a Peregrine flies over, you have to crouch and not budge an inch for at least 10 minutes, even if you are taking a short-cut across a muddy estuary.

But not every partridge knows that there is an exception to the do-not-budge rule, if the tide is coming in..

This story had a happy ending, with the bedraggled partridge coming to its senses and floundering to shore after 25 minutes.
