[Tweeters] Renton airport anti-bird measures question

Runway incursion is a huge issue for airports. Sea-Tac has a
well-established program for leaving "sentinel" birds in place and removing
migrants and juveniles, hopefully before they have a disastrous meeting.
Salt Lake City, Vancouver, Portland and many, many others are using various
methods to try to reduce numbers of dead birds AND threats to humans.

You wouldn't think that a sparrow or other small bird could cause a
problem, because when you hit them with your car, there usually isn't too
much damage. But if your vehicle is going 150-250mph, that little bit of
matter carries an incredible damage potential.
