Piglets when reared outdoor.
There are many examples and footage of wild golden eagles taking lambs, hunting Chamois and even one of a child being lifted off the ground in Canada. Others show a white tailed eagle returning to it's nest with a lamb ( video by Gordon Buchannan on Isle of Mull ).
I cite these purely as examples of the capabilities of this immensely powerful family of birds.
Personally I would have loved to see White tailed Eagles soaring over the North Norfolk coastline and I recall a juvenile hanging around not too far away from Sandringham c.15 years ago during winter.
R.D. has done wonders for bird of prey study and reintroduction. Why haven't they looked at reintroducing W.T. Eagle along the North East Coast of Scotland? Closer to Scandanavia and plenty of habitatl for feeding and nesting whilst not too densely populated.
Hi Pat. Wasn't the Canadian video a hoax? I know Tomkies wrote that of the (very) few lambs taken, many were already dead and not killed by the Eagles. He did acknowledge there were some examples of live lambs being taken though.
