There is little evidence documenting the prevalence of plastic nest incorporation for different seabird species and populations, and even less detailing the source of such debris as nesting material. This study presents a baseline dataset on the presence of plastic in the nests of five seabird species on Lady Isle, Scotland using a novel and repeatable methodology for quantifying plastic incorporated into nests. Plastic was found in 24.5% to 80% of nests of all species. We analysed pellets of regurgitated material and the spatial distribution of herring gull nests containing plastic in the context of the tide and nesting habitat. Differences in the types of plastic found in pellets and nests suggests that plastic incorporated into herring gull nests was not derived at foraging sites and likely collected from the local environment. Targeted beach cleans before the breeding season could help minimise the quantity of plastic available to herring gulls.
很少有证据记录不同海鸟物种和种群中塑料巢材的普遍程度，更不用说详细说明作为筑巢材料的这些碎片的来源。本研究使用一种新颖且可重复的方法，在苏格兰 Lady Isle 上的 5 种海鸟巢中存在塑料的情况提供了一个基线数据集。在所有物种的巢中，塑料的存在率为 24.5%至 80%。我们分析了反刍材料的小球和含有塑料的银鸥巢的空间分布情况，这些巢与潮汐和筑巢栖息地有关。在小球和巢中发现的塑料类型的差异表明，银鸥巢中包含的塑料并非来自觅食地，而是很可能从当地环境中收集而来。在繁殖季节之前进行有针对性的海滩清理可以帮助减少银鸥可利用的塑料量。
