Well glad we've worked out the difference between buzzards, vultures and seagulls! Ha no said buzzard did not drop a leaflet to warn me (mind you just as well as i can't read German, too many long words!) And no i wasn't eating chips whilst running at the time and I actually thought i was a fair distance from the trees where the nest must be.
I was not attacked thankfully as when i came back and went on the internet to search if any attacks have been recorded they have and they don't sound like much fun. The buzzard swoops down at you from behind, so as you are running and not looking behind or up you don't realise they are on the way until either they attack you using their beaks or talons (no apparently no recordings of them using a handbag!) or they swoop very close to you then climb up high leaving you in no mistake that they are there and could easily be getting ready to swoop back and attack!
I have therefore decided that i am happy with the top/back of my head and will keep away!
Know what you mean about Cornwall and seagulls though, St Ives being really bad.
