I've been lucky to be able to watch 3 different Hawk Owls over the 
years, and they seem to be incredibly good at spotting and catching 
rodents with one quick dive.  I saw very few misses.

The fascinating thing to me is that at least one of the three kept a 
couple of food caches nearby.  So it hunted pretty much without 
stopping, and if it caught more than it needed, it stuck the dead prey 
item in one of the caches for future meals.  I never saw and nobody I 
talked to ever saw it actually take and eat prey from one of those 
caches since there were abundant mice/voles and it had no problems 
feeding itself.

I've never heard of other owl species doing this, has anyone else?  I 
can't help but think of how useful a habit that would be if there was a 
melt/freeze cycle that put a heavy crust of ice over the snow and made 
it so much harder to catch rodents scurrying through the snow under the 
ice layer.
