EDINBURGH, Scotland, Aug. 13 (UPI) -- Beavers, hunted to extinction in Great Britain 400 years ago, are making a comeback in Scotland, with re-introduced animals raising families, researchers say.
The first newborn beavers born in the wild since their reintroduction last year have been spotted in a Scottish forest, the BBC reported.
At least two kits, estimated to be 8 weeks old and from different family groups, have been seen in Knapdale Forest in Argyll. They are the first offspring discovered since 11 beavers were brought to the United Kingdom from Norway as part of the Scottish Beaver Trial.
Seeing the new arrivals was an "amazing" experience, Christian Robstad of the Royal Zoological Society of Scotland said.
"After weeks of patient observation, we were finally rewarded with not just one kit being spotted but a second kit from a different family group as well," he said.
Simon Jones, trial project manager, said the kits marked a "fantastic step forward" for the trial.
"Both these beaver families are real trial success stories, having settled into Knapdale very well," he said.
