“Puffins have been seen on the Isle of Muck in County Antrim for the first time in years, after a major scheme to remove invasive brown rats.

It is the first time the vulnerable seabird has been recorded on the tiny island off Islandmagee since Ulster Wildlife took over the management of the seabird sanctuary 25 years ago.

A programme of rat eradication began in 2017 and winter grazing has now been implemented to keep vegetation low, so predator cover is reduced.”
