Scientists behind a red squirrel monitoring project in County Fermanagh have been surprised after finding an even more elusive mammal has been 'photo-bombing' their research.
Pine martens have been spotted by cameras in the Fermanagh woodlands, more than red or grey squirrels.
The animal is considered to be Ireland's rarest native mammal.
The results have forced researchers to rethink and they will now include pine martens in the survey.
They are now recruiting volunteers to take the project forward and get a better picture of both the red squirrel and pine marten populations in Northern Ireland.
The Fermanagh Citizen Science Red Squirrel Project originally set up cameras in 70 woodlands across the county.
