Thanks for that link Gammy...wow !!
I had a close encounter
walking along the coast at St Bees Head. The path was a few yards inland from the cliff top and two harriers came in from the sea, but not visible to me. I didn't hear them either as per usual the sound doesn't reach you till after. They must have pulled up just before the cliff so the first I knew was when they were going over me.
I feel to the ground in surprise/shock, needless to say a change of underwear was required jeeez !!
