Went head to head with a flock of ducks a couple of years ago in the Borders. I was No 3 in a 4-ship coming out of a 'Concealed Approach and Departure' in trail (about 50ft, 70 kts at the time). No 1 must have woken them, No 2 spooked them and they appeared in front of me. I took out 4 of them, and put down in the nearest field.
When I went to the nearest farmhouse to use their phone, I explained what had happened. Their response was "Not the ducks in the wood, we have been rearing them for years!" They let us use their phone, but that is as far as the hospitality went!
Apart from lots of blood, guts and feathers, no damage to the cab - so we made a hasty exit!
