A study by the National Trust suggest seabirds around the UK coastline are being hit by a "triple whammy" of extreme weather, predators, such as foxes, rats and non-native mink, and disturbance by human walkers and their dogs.
Gwen Potter, a National Trust Ranger in Ceredigion, in west Wales, told the Today programme that colonies of birds including little terns and Atlantic puffins have been particularly hit by recent storms and "dogs getting loose".
"You need to be aware that during the breeding season, there will be nests...that there might be issues with animals that live there," she added.
First broadcast on BBC Radio 4's Today programme on Thursday 28th August.
