Plastic debris is often ingested by marine predators and can cause health disorders and even death. We present the first assessment of plastic ingestion in Mediterranean seabirds. We quantified and measured plastics accumulated in the stomach of 171 birds from 9 species accidentally caught by longliners in the western Mediterranean from 2003 to 2010. Cory's shearwaters (Calonectris diomedea) showed the highest occurrence (94%) and large numbers of small plastic particles per affected bird (on average N = 15.3 ± 24.4 plastics and mass = 23.4 ± 49.6 mg), followed by Yelkouan shearwaters (Puffinus yelkouan, 70%, N = 7.0 ± 7.9, 42.1 ± 100.0 mg), Balearic shearwaters (Puffinus mauretanicus, 70%, N = 3.6 ± 2.9, 5.5 ± 9.7 mg) and the rest of species (below 33%, N = 2.7, 113.6 ± 128.4 mg). Plastic characteristics did not differ between sexes and were not related to the physical condition of the birds. Our results point out the three endemic and threatened shearwater species as being particularly exposed to plastic accumulation.
塑料碎片经常被海洋捕食者吞食，并可能导致健康问题甚至死亡。我们首次评估了地中海海鸟吞食塑料的情况。我们从 2003 年至 2010 年期间，在西地中海被延绳钓意外捕获的 9 种鸟类的 171 只鸟的胃中，定量和测量了积累的塑料。黑叉尾海燕（Calonectris diomedea）的出现率最高（94%），每只受影响的鸟体内的小塑料颗粒数量也最多（平均 N = 15.3 ± 24.4 个塑料和质量 = 23.4 ± 49.6 毫克），其次是黄眉信天翁（Puffinus yelkouan，70%，N = 7.0 ± 7.9，42.1 ± 100.0 毫克）、巴利阿里群岛海燕（Puffinus mauretanicus，70%，N = 3.6 ± 2.9，5.5 ± 9.7 毫克）和其余物种（低于 33%，N = 2.7，113.6 ± 128.4 毫克）。塑料的特征在性别之间没有差异，也与鸟类的身体状况无关。我们的研究结果表明，三种特有且受到威胁的海燕物种特别容易受到塑料积累的影响。
