The catch? It would involve a controlled experiment where you removed by active nest destruction and trapping and translocation of adults in the experimental area. Let's say 50 of each species over a few years. Option 2 would be shooting/trapping/killing of adults (same number). A moral, ethical and ideological minefield, but those 50 Buzzards could put an end to all prospect of lethal controls and so protect many more, for the forseeable future.
If you could look into a crystal ball and know that the answer you got would be the one you needed/wanted (i.e. they're 'innocent' of the charges), would you accept this price for that evidence? Either option?
Alf, I don't necessarily disagree with your ideas but I would have thought that this would be at least Phase 2 and probably later in any research. Far better to find out if the 25-30% loss rate is correct first before taking any direct action. If it is wrong in the first place then there is no way forward and no justification for the removal experiment wouldn't you agree?
If it was proven, there would be no argument but would it not be a no-brainer that removal of any buzzards would reduce losses according to your theories? My fear is that removal of buzzards could be made to look as though it increased yields possibly even dishonestly (sorry but we have to address this possibility) or it would simply be claimed that any increase (no matter how small) in yield would prove the original theories and be sufficient justification for widening the removal programme? No, to me the first step should be verification of the claims that have been made to support the calls to take this action and then make decisions on what happens next.
