martin, you can't evaluate prey choice if you don't know the background levels of prey available to each predator. so, since 80,000 birds from N America averages over all sorts of factors that contribute to unequal prey species distribution and abundances (biogeography, latitudinal, elevational, forest type, etc factors), AND there was no attempt to measure prey abundances with respect to each predator stomach, you simply cannot make the inferences from these data that you wish to.
so your claims are falling flat without having to evaluate a specific paper. you have no way to even show what you are claiming is shown. that is my point, that you are simply waving hands. further, you don't even have an alternate hypothesis, just 'darwismus is wrong for natural selection can not arouse mimicry just like great Eimer said in 1914 in german'.
Daniel has a set of specific positive claims (although it took a while for him to formulate them positively, and not like you are doing, ie 'selection cannot explain X'). we have been trying to get you to make your claims for months now, and you refuse to do so. bring it, don't sing it.
