Not the sort of thing you expect in Warwickshire. I'm sure it does happen, particularly on breeding colonies on the coast but I cant recall seeing Common terns 'bombing' a couple of Hobbies. Not just dropping their droppings but actually aiming them. No hits were seen but plenty of near misses. The birds in question were at Mill pool, Alvecote.
