Hey folks, aren't we missing the point a little?
Even if the odd Red Kite were able to catch a young Red Squirrel now & again ...
So What!
The Lord wrote: "...
devastating" local populations of the threatened Red Squirrel"
Yeah Right! Come off it '.. me Lord!
.... it's not as if Red Kites are about to
exterminate the Highland Red Squirrel population!
I've seen how these guys operate first hand.
As a Keeper on an Irish shoot, many years ago, I watched a curious
Peregrine fly out over the guns, during a Pheasant drive, when suddenly a couple of F'in Guns took pot shots at the Peregrine!
I immediately saw
RED & as a flanker out on the field that day, I was able to run forward shouting
"Don't Shoot, it's a Peregrine"!
Well, I've never seen a Lord so angry ... or red faced!
Can you believe it, he actually tried to fob the whole thing off by saying
It was OK, it was just a Kestrel! 
He later told me that if I ever behaved like that again, I would be sacked ... of course I didn't give him the opportunity & left soon after that!
I'm afraid most of these guys don't
really care about their wildlife, they're in it for the Money!
Cheers
