please let it be true, please.
-
This would make one legged ducks excellent at negotiating roundabouts (assuming right left missing)
-
I am not so sure that would be true because we had a duck like that and he could still swim where he wanted I never noticed if he swam in circles.
I do see why that would seem so kind of like when rowing a boat with one ore or a boat using only the left rudder.. would stand to reason that a duck with one leg would swim in circles. I think though that the duck has the ability to shift his body weight from left to right to help make up for the loss of limb. I am no expert but wouldn't that be the difference in a boat and a duck with one leg. The boat goes in a circle lacking the ability to shift its hull to accommodate the loss of working or or rudder. Am I completely off In a small boat you would have to switch the ore from right to left in order to maintain a semi forward motion rather then a circle... so I am not sure. with a duck he certainly cant remove his leg and shift sides so I am assuming he shifts his body weight some how!

Well, which is it Neil - please, make up your mind - right or left.
Sheesh!

The duck was using a "J" stroke, the same stroke we were taught in Boy Scouts to paddle a canoe when only one person is in it.

I thought canoes generally only had room for one person and the paddle had a blade at both ends.

I so hate it when the quote thing does NOT work !!!!

I do have a reputation of being Mr Ambiguity to maintain sir !!
But in this case I typed 'Left' when I should have typed 'LEG'

LOL LOL!

A kayak is generally designed to hold just one or two people whereas a canoe is generally designed to hold many people at once... Like you may see off Hawaii! Going between the islands of Tonga and the main land, it is quite common for the men to travel in a canoe to go to school. I don't know if it is all the people there or just a few, but I took it it was common! I have a missionary friend who is from Tonga and he says it is common for him and his family!!

I think it would have more trouble 'treading water' or just 'being stopped'
Poor ducky - but probably better than having 4 [:o]

OHHHHHHHH.he's cute, but poor little thing.. I wonder how he gets around does it hamper him or is he adapted well?

Oh ok. I was a bit suspicious about the two-handed grasp on the duckling.

Cute picture Alandriel. But how does this duck swim? Any pictures of that?

Very fast!
heh - I've just got a vision of it swimming like an old Mississippi river boat; the ones with the paddles at the sides. [:D]

You sit in a kayak and use a double bladed paddle, but you kneel in a canoe and use a single bladed paddle. JimBob is almost certainly correct - it probably uses a 'J' stroke, combined with angling it's leg through, or just over, it's centerline (as it does when standing). Also, it's foot isn't rigid so it could change the shape of it's foot through the stroke.
