Sick Seabirds Warn Of Plastic Pollution In The Oceans
It’s a late May night on Lord Howe Island, and the moon gleams across the volcanic mountains and white sand beaches of this six-mile long isle off the east coast of Australia. While most people are tucked inside their houses or hotels, conservation biologist Dr. Jennifer Lavers and her colleague, naturalist Ian Hutton, don headlamps and bike to the flesh-footed shearwater colony on the northeast side of the island. Lord Howe Island is one of the two main breeding areas for this seabird in the southwest Pacific Ocean (the other is in northern New Zealand). Tonight the colony bustles with 90-day-old chicks flapping their wings as they prepare for their first 6,500-mile flight north to the Bering Sea. Even though many seabirds are affected by plastic pollution, the plight flesh-footed shearwater illustrates how widespread the problem is.
Lavers and Hutton set up a makeshift research station in the colony, and handpick chicks to weigh, measure, and take feather samples. They also undertake a lavage process, guiding a tube down each bird’s throat to flush out its stomach contents. This part may seem gruesome, but the lavage provides important information about shearwater diet and nutrition. If a fledgling’s parents fed it well, it will regurgitate natural food sources like squid and fish. But more often than not, chicks will cough up something that does not belong in their stomachs – plastic.
