Plastic ingestion by adult Procellariiformes has been widely recorded, but few studies have evaluated intergenerational transfer. We assessed the prevalence of plastic particles, as well as their basic characteristics, in the gut content of dead Cory's shearwater fledglings stranded by light pollution on Canary Islands. Eighty-three percent of birds were affected, containing on average 8.0 plastic pieces per bird. The average plastic weight per bird was low (2.97±3.97mg) compared with other petrel species. We found no relationships between plastic loads and body condition or body size, but negative effects may be hidden or delayed. We propose to use the fledglings stranded by light pollution to carry out more precise studies to understand the potential hidden costs of plastic ingestion; and to monitor in a long-term the marine debris to develop management actions for the control of pollution at the marine environment.
成年信天翁类动物吞食塑料的现象已被广泛记录，但很少有研究评估其代际传递。我们评估了在因光污染而搁浅在加那利群岛的 C Cory's 海燕幼鸟的肠道内容物中塑料颗粒的流行程度，以及它们的基本特征。83%的鸟类受到影响，每只鸟平均含有 8.0 块塑料。与其他海燕物种相比，每只鸟的塑料平均重量较低（2.97±3.97mg）。我们没有发现塑料负荷与身体状况或体型之间的关系，但可能存在隐藏或延迟的负面影响。我们建议利用因光污染而搁浅的幼鸟来开展更精确的研究，以了解吞食塑料的潜在隐藏成本；并长期监测海洋垃圾，以制定控制海洋环境污染的管理措施。
