<<What the f do ATC believe will happen if I land a 250 ton 747 on a dead bird? A complete waste of time and fuel.>>
A somewhat uncharitable comment if I may say so. I was on duty at Heathrow early one morning when many bird strikes occurred. Both runways were closed and a number of aircraft were sent around. During subsequent runway inspection over 200 carcasses were removed - a record at the time. ATC will take action to preserve safely; that this may not be agreeable to some pilots is unfortunate.
