N2  - Since June, 1963, considerable quantities of pumice flotsam have been washed up at Macquarie Island.  The Southern Skua, Catharacta skua lonnbergi, has largely adopted pumice as a gizzard-stone, and also swallows pumice pebbles to digest attached goose barnacles, Lepas australis. Pumice subsequently regurgitated by Skuas has been dispersed widely over the island.
