I agree with you that they take on harriers as I observe it several times a week. I cannot comment on their re-action to magpies, as my earlier culls have cleaned them out, but I suspect it would be the same as harriers. I can make the observation that they co-exist with the ducks, all varieties, tuis, waxeyes, sparrows, starlings , minors (unfortunately), grey warbler, peasants,, pheasants, quail, crimson rosellas (unfortunately, again) blackbirds, fantails, poultry and the thrush's who also inhabit my block.
Noisy, they may be but killers......................I doubt it. I suspect that somewhere down the line, they are getting bad and unjustified, press comments.
But if you want to talk killers, lets talk about the Pukes.
