Artist Charles Tunnicliffe and his wife, Winifred, also an artist, moved to Anglesey in 1947. Overlooking the Cefni estuary, with pools created by an embankment built in 1811 to reclaim land, their home – 'Shorelands' at Malltraeth - doubled as a hide, affording spectacular views of the resident and migrant bird life. Tunnicliffe here catches footage of gulls feeding in flocks on their patio and wall, the flapping of their wings a sight to behold.
