The RSPB, in particular, are not adverse to killing Corvids, so it's not a huge leap to expect them to turn their attention towards Sparrowhawks. However, if you have read the report, you'll see that Farming methods, amongst other Human activities, is the main cause of species decline. What I do "trust" is the evidence of evolution; I find it inconceivable that any species would have successfully evolved with the propensity to cause the extinction of it's prey species.But I won't comment further; if you feel the need, then start a new thread. This thread is titled, "The Under Estimated Sparrowhawk", we are both way off of that topic.(BTW, I won't comment on "Songbird Survival", but I do find it interesting that you mentioned them)</blockquote>
