Plastic particles and Other anthropogenic materials were recorded from the regurgitations and the stomachs of seabirds at Macquarie Island; these were ingested both at sea and on land. Eight percent of regurgitated casts from Macquarie Island Cormorants contained polystyrene beads. Plastic particles were recorded from the stomachs of Southern Giant Petrels, Subantarctic Skuas, and Kelp Gulls. Birds examined in 1988 had a higher frequency of occurrence of foreign objects than birds examined prior to 1980.
