Methods of data collection, processing and analysis to estimate harbour and grey seal diet are described in Wilson and Hammond (2016) and Hammond and Wilson (2016), respectively. For comparison of diets, the data were grouped into two seasons: spring/summer (harbour seals: March-August; grey seals: April-September) and autumn/winter (harbour seals: September-February; grey seals: October-March). For comparison of diets, the data were grouped into the following regions: southern North Sea, south east Scotland (Firth of Forth, Isle of May, Rivers Tay, Eden and Ythan), Moray Firth, Orkney, Shetland, Inner Hebrides and Outer Hebrides.
