From a related question, I got to thinking about bird strikes again and the fact that they are sucked into the engine at great velocity.
If a pilot had 5 to 10 seconds of warning time, would throttling down the engines to idle be a good idea? Would it save those engines even if a bird hit the intake fan? This would of course be a temporary measure, intended to prevent the birds being sucked in harder or faster than otherwise. Once the birds passed, the engines would be throttled up again.
I'm thinking about large commercial jets like the Airbus A320.
EDIT: one concern I have is that at high throttle, the engine will suck in objects from a wider area than just the engine inlet. Is this assumption true?
