What is the difference between a duck?

Question

That's the whole riddle. What is the classical response (the correct answer)?

Answer 1

Difference between a Duck?

The official answer to that question is:
"one leg are both always the same".

However, a generally accepted better answer is:
"on land it is walking, in water it is swimming"
because it actually answers the question by the rules of the english language.

But since so many people know that question,
variations for that same class that the question is usually asked in would include:
What is the state of a Duck?
Why is a Duck?
If not a Duck, then what?

Answer 2

one of its legs are both the same
The Difference Between a Duck
by Henry Quince
I posed a riddle that drew no answer:
I asked the difference between a duck.
Mallard or dabbler, teal or merganser—
same difference, I say. Don’t tell me you’re stuck!

This question’s your task, now please begin it:
What’s the difference between a duck?
Logic won’t solve it in half a minute;
You’re most unlikely to crack it by luck.

No use to try a surreal suggestion
like “More kids went to Scout Camp than I did.”
Maybe, but please will you answer the question:
I’m waiting to hear what you’ve decided.

And it doesn’t turn on a silly trick
like “May a man marry his widow’s sister?”
No, the solution won’t make you sick,
nor will you write me off as a twister.

One answer deserving of ridicule
asserts “The higher it flies, the more.”
The singular’s there, but where’s the dual?
Oneness and twoness is at the core.

Now here’s what looks like a pretty good shy:
“One has feathers, the other quacks.”
It may seem apt, but I’ll tell you why
it’s not the best and what it lacks:

Not two ducks were given, but only one,
the difference between which you must name.
The answer—what wonderful webfooted fun!—
“One of its legs are both the same!”
