The council has contacted the Royal Society for the Protection of Birds and Scottish Natural Heritage over fears about puffin numbers on Treshnish.
Community councillor Fiona Brown also blamed sea eagles for the destruction of wildlife in the south of Mull. She said: “There is not a single rabbit left at Pennyghael. The hill used to be alive with them but now they are all gone.”
A spokeswoman for Scottish Natural Heritage said: “A study in 2003 showed that, while sea eagles take some lambs, they are either dead or in poor condition.
“We have set up a scheme where farmers can apply for funding to trial measures to improve the condition of sheep before and during the lambing season, helping to stop predation by eagles.”
RSPB Mull officer Dave Sexton said: “There are now more puffins breeding on Treshnish than there were before white-tailed eagles were reintroduced to Scotland in 1975.”
“Immature white-tailed eagles will sometimes gather in small numbers at autumn and winter roosts.
“Such gatherings gives rise to occasional concerns that there are suddenly too many of them.”
