In addition to monitoring trends in plastic pollution, multi-species surveys are needed to fully understand the pervasiveness of plastic ingestion. We examined the stomach contents of 20 bird species collected from the coastal waters of the eastern North Pacific, a region known to have high levels of plastic pollution. We observed no evidence of plastic ingestion in Rhinoceros Auklet, Marbled Murrelet, Ancient Murrelet or Pigeon Guillemot, and low levels in Common Murre (2.7% incidence rate). Small sample sizes limit our ability to draw conclusions about population level trends for the remaining fifteen species, though evidence of plastic ingestion was found in Glaucous-Winged Gull and Sooty Shearwater. Documenting levels of plastic ingestion in a wide array of species is necessary to gain a comprehensive understanding about the impacts of plastic pollution. We propose that those working with bird carcasses follow standard protocols to assess the levels of plastic ingestion whenever possible.
除了监测塑料污染的趋势外，还需要进行多物种调查，以充分了解塑料摄入的普遍性。我们检查了从北太平洋东部沿海地区收集的 20 种鸟类的胃内容物，该地区已知有高水平的塑料污染。我们没有在黑脚信天翁、斑海雀、古鸬鹚或海鸠中观察到塑料摄入的证据，在普通海鸠中也只有低水平的摄入（发病率 2.7%）。小样本量限制了我们对其余 15 种物种在种群水平趋势上得出结论的能力，尽管在黑背鸥和黑叉尾海燕中发现了塑料摄入的证据。为了全面了解塑料污染的影响，有必要记录广泛物种中塑料摄入的水平。我们建议，从事鸟类尸体研究的人员尽可能遵循标准协议来评估塑料摄入水平。
