When we're sitting comfortably inside a passenger jet, it's hard to imagine the 
impact a bird weighing a couple of kilos would have on any component when it 
strikes at up to 900kmh.  The sort of protection to prevent something the size 
and weight of a goose from entering the engine at all would prevent the engine 
from working properly.  At best it might be possible to "dice" the bird a bit 
before it hit the engine in the hope the engine would not be damaged, but if it 
was feasible I'm sure it would have been done.

The exceptional thing about the Hudson River incident was that the geese flying 
in their typical "v" formation were sufficiently spread out at just the right 
angle that both of the jet's engines were hit and failed.  I've never heard of 
another incident where all the engines of an aircraft with more than one engine 
failed due to bird strike.

I don't think there's really anything practical that can be done about it and 
frankly the risk is incredibly small or it would have happened long before now, 
given the number of aircraft flying all around the world every day.
