BirdWatch Ireland, which is responsible for a nature reserve off the Kerry coast, says it was never consulted about an ad that was filmed off the island.
The TV ad is part of a major rebrand of the telcommunications company, Eir, formerly eircom.
A drone filmed footage closed to Little Skellig which is a special protection area for birds and is a BirdWatch Ireland reserve.
BirdWatch Ireland alleges it was never consulted.
The Sunday Times says that Eir insists it adhered to Irish Aviation Authority regulations.
According to the newspaper, these regulations require those who use drones for commercial purposes to get an an ‘aerial works permission.’
Dr Steve Newton is with BirdWatch Ireland.
He says up to 100 thousand gannets could be on Little Skellig island during breeding season.
