lynx

In the Vermont woods where Mr. Hoagland lives, coyotes have replaced wolves while bobcats have taken the place of Canada lynx.

The zoo says the food provided in this way is "reminiscent of what it would naturally hunt in the wild" - and that this is especially true for the Eurasian lynx.

Other rewilding efforts - both legal and illegal - causing debate include sea eagles, lynx, wolves, elk, and even some species of butterfly, while sightings of wild boar on Dartmoor sparked division.

Three lynx that were illegally released in the Highlands earlier this year have moved to a new permanent home just a few miles from where they were found.

"Our nature is very fragmented, due to railways and streets and cities. And this means we created a lot of barriers for the lynx, which leads to inbreeding," Dina says.
