"Birds don't fly at night"
You can't convince me!
I took off from El Monte @ 4:00AM on an IFR flight to Loreto Mexico and picked up a bird that lodged between the second and third cylinders on the right side and when I broke out of the storm about Conception bay and the temperature went up about 10 degrees C I siezed a valve. I had to pick it up on climb since there aren't any birds at 11,000.

This came up recently in another FR aviation thread. The record height for aircraft - bird smackdown is >30,000 feet! An airliner engine ingested a bird at cruise altitiude.
