Just to put a different slant on it, we're normally below 500 ft with a pretty big radar in the nose - and we hit our fair share of birds (perhaps one every 18 mts or so?? I’ll have a dig thro’ my logbooks). I'm pretty sure that if you compare our birdstrike stats to those types who operate in the same environment without radar (Harrier, Jag and Hawk for example), they are quite similar.
Then again perhaps it's just weather radar they don't like!
