Pine martens haven't been seen in Somerset for more than 100 years.
But conservationists got a pleasant surprise, after one was spotted on their night vision camera.
The animal was seen in the Mendips by the team at the Patch Wilder project.
Staff were monitoring the 15 acres of grassland and woodland at the time, to see what animals were around.
