I was watching ducks down at the river change location (but only moving about 30 feet): Some made as if to take flight, flapping like crazy and running their little webbed feet across the water, only to plop down again before reaching v1; Others stayed in the water and calmly feet-paddled their way over to the new spot.


And then YKYAEM when you wonder about the effect of duck efficiency preferences on duck evolution...
