Newton, Sally and Peter G. Ryan Using Skua Pellets to Monitor Plastic Ingestion by Stormpetrels: An Alternative to-Destructive Sampling Fitzpatrick Institute, University of Cape Town, Rondebosch, South Africa 34 The stomach morphology of petrels and storm-petrels (Procellariidae and Hydrobatidae) precludes non-destructive sampling of ingested plastic particles. This complicates attempts to monitor the abundance and characteristics of plastic ingested by these seabirds which have among the highest levels of plastic ingestion recorded for any marine organisms. One possible way to monitor plastic ingested by petrels is to record the amount of plastic in pellets regurgitated by skuas Catharacta spp. after feeding on petrels. Subantarctic Skuas C. antarctica are predators that regularly consume petrels breeding at Subantarctic islands; The indigestible remains of their avian prey are regurgitated in pellets, comprised of bones, feathers and persistent stomach. contents (primarily sguid beaks, pumice and plastics). A previous attempt to use skua pellets to assess plastic ingestion among small petrels found several biases, including the underrepresentation of small particles (
35 pellet. The only drawback with storm-petrels is that some 30% of pellets have to be discarded because they contain the remains of more than one prey item. Schofield, David, Andy Stamper, Brent Whitaker, and Joseph Geraci A Young Whale, the Victim of Ocean-Borne Plastic National Aquarium, Baltimore, Maryland, USA On Thanksgiving Day, 1993, an orphaned pygmy sperm whale, Kogia breviceps, was found stranded in a New Jersey inlet. The animal, which was rescued by the Brigantine Stranding Center, New Jersey, was air-lifted the following day by the Coast Guard to the National Aquarium in Baltimore. There she was placed in a large pool and given round-the-clock intensive care. The animal was thin, would eat very little, and showed signs of gastrointestinal disease. She listed to one side, swam feebly, and was unable to dive more than a few feet. An examination of her stomach revealed the presence of impacted plastic. Repeated attempts to retrieve the debris were finally met with success, after which the animal's behavior and appetite improved dramatically. In her short stay in Baltimore, she has gained 112 pounds and now weighs 318 pounds. The National Aquarium in Baltimore's Marine Animal Rescue Program is presently preparing the whale for release back to the sea. A healthy whale now, but will she once again mistake the undulating movement of plastic for that of her primary diet, squid? Slater, Janet E. Plastic Ingestion by Seabirds in Tasmania, Australia Tasmanian National Parks and Wildlife Service, Hobart City, Tasmania, Australia The stomach contents of 24 dead, beachwashed fairy penguins, Eudyotula minor, 3 short-tailed shearwaters, Puffinus tenuirostris, and 2 fairy prions Pachptila turtur, were examined for plastic ingestion. Plastic particles were found in three penguins and two shorttailed shearwaters. Articles included pieces of soft plastic, plastic beads, pieces of hard plastic and one lid from a medicine bottle. In one bird, the plastic appeared to have obstructed the passage of food into the intestine, causing the stomach to swell and burst through the body wall. Evidence suggests that the plastics originate from a variety of sources, and these and the hazards of plastic levels in the seabirds are discussed.
