Interesting to note the Very low number of Birdstrikes mentioned by Twostroke earlier, we had 31 last year the vast number of which were involving birds of the non priority group (Small single birds) not Gulls,waders, Geese, starlings etc, also near misses & possible strikes with no evidence are all reported.

don't rely on it to clear them if you are a pilot.
