Try to spot a Thrush against a back drop of the ground at fifty odd feet above the threshold with enough time to decide what you're gonna do and then do it.
Don't worry about the thrushes. They aren't that big. Worry about the cranes, the eagles, the geese, and the vultures and anything else that is big enough to do serious damage.
Your engine is designed to chop up and spit out a thrush. But take evasive action on a flock of starlings if you can. The feathers per second count down the engine may exceed its capacity.
