Hunting has been going on for a lot longer than centuries but I take your point. However these people are not hunting, they are chauffer driven up to the firing point and then the beaters send the Grouse toward them in such numbers they need someone to reload a second gun. Now lets not blame the Peregrine, Buzzard or Sparrow Hawk on low numbers of Kestrels although as you say there is some overlap which is the balance of nature and certainly wont make Kestrel become extinct. The gamekeepers/landowners are responsible for the killing of our birds of prey, time and time again satellite tagged birds go off the radar over Grouse moors, there is plenty of evidence to show this including video. The carcases of the Grouse are left in open stink pits to lure in predators like Badgers and foxes even Stoats and Weasels which are exterminated. The gamekeepers even kill the Mountain Hare because it competes with the Grouse for food. I do understand that the RSPB cull the members of the Crow family from time to time to save ground nesting birds eggs from over predation. There are more Carrion Crow in Britain than any other European Country one reason for this is that there are very few Goshawks, 40% of their diet consists of the Crow family. We have to decide if we want to re connect and live with nature or watch its extinction. All life is special.
I fear there's no chance of saving the Rhino or the Tiger we cant even save the House Sparrow or the Hedgehog. Starlings have been destroyed at a rate of 150 an hour (40 million) since the 1980s. Despite it being illegal to kill birds of prey some of which have been re-introduced to the UK, satellite tagged birds are still being trapped, poisoned and shot by gamekeepers so that the rich and famous can blast away at the Red Grouse, killing so many they have to be buried in pits. Its happening in our lifetime, our great grandchildren or even our own children do not have the same opportunity to see that which we have had the opportunity to see. We cannot preach to others and ignore our own faults. Our future grandchildren will wonder why we did nothing.
A friend of mine who had a season ticket in the main stand for many years did not renew after the err Colman era and has never been back to even one game since so I would think our last home game this season may be the last game completely for some.
As others have pointed out its a habit you can get out of in time
