“In 1949 Grace and Ian Telfer, an {{w|Natural History Society of Northumbria|NHSN}} member, decided to mark {{w|Pinniped|seals}} in an attempt to follow their movements. Though {{w|grey seal}}s are resident on the {{w|Farne Islands|Farnes}}, nothing was known about them outside the breeding season. The first seals were tagged in 1951, and within fifteen days the first marked seal was recovered in Norway. This was ground breaking research as no one had realised how far the Grey Seals were traveling.”
