When I lived in Argyll we were plagued by a female Spar one winter (usually it is one particular individual raptor that causes problems, not a whole species). Our pigeons weren't racers, just pets, and we readily accepted that some would be taken by predators (there was a Peregrine nest within sight of the house) - but this particular Spar was something else! She decimated the flock from around forty birds to a dozen very frightened ones that hardly dared leave the shed. One bird, a white Frillback, had been rescued from her clutches, but her back had been partially eaten. The last straw came when she started entering the shed to kill them! One day we managed to catch her, box her up, pop a red pigeon ring on her leg and give her to a friend who was driving down to Glasgow the next day - he consequently released her on farmland on the outskirts of Glasgow.
Two weeks later we heard the chooks alarm calling and were just in time to see a Spar snatch up what we thought was a OE Game chick. She landed on the drive and my uncle managed to sneak down and take a couple of pics of her. Two surprises: the chick was in fact a baby rabbit (only the second time I've witnessed a Spar killing anything bar birds); and the Spar had a bright red pigeon ring on her leg!
Anyone who doesn't think raptors can cause problems with livestock, game and colonies of rare birds is living in cloud cuckoo land to be honest. However, as I stated before I believe it is individuals who cause the problems (and very few of those), so the call for the wholesale slaughter of raptors is ridiculas IMO. Personally I would never kill any raptor (and I realise I'll probably get flack from some for breaking the law when relocating the Spar), I've always believed it is prey numbers that control predators, not vice-versa.
It is all too easy to accuse anyone who wants to cull raptors of being a 'redneck' when one hasn't been on the receiving end of raptor problems - name-calling simply inflames the situation IMO.
