Small birds are unlikely to do a lot of damage at typical GA speeds.
You're obviously not a motorcyclist. Sorry to contradict you, but this is so untrue.
I landed at a French airfield a few years ago just after a Cessna 172 landed following a bird strike. The father, mother and daughter had just been rushed off to hospital. The windscreen was shattered. There was blood galore inside the aircraft, and it was not just from the bird. There was much internal damage and was a fairly horrific sight.
Cocooned in a car or aeroplane cabin, one doesn't realize what it is like to be doing just 70mph against the air, as on a motorbike. And the force of impact increases with the square of the velocity. 90mph gives almost double the force of 70mph and on a motorbike you really know it, and that is slower than even a Cessna 172 in the cruise.
