研究表明，黑脚信天翁 (Phoebastria immutabilis) 和黑足信天翁 (P. nigripes) 会摄入塑料碎片，研究表明其幼鸟的消化内容物中含有塑料，但几乎没有记录表明成年信天翁在觅食时摄入塑料的频率和数量。在这项研究中，我们对北太平洋副渔获物收集的 18 只莱桑信天翁和 29 只黑脚信天翁的消化物中的塑料进行了量化。我们发现，在检查的 47 只鸟中，有 30 只摄入了塑料，黑脚信天翁摄入塑料的频率 (83.3% n=18) 高于黑足信天翁 (51.7% n=29) (X2=4.8，df=1，P=0.03)。尽管这两个物种摄入的塑料质量（平均值±标准差=0.463克±1.447）低于之前在信天翁雏鸟中观察到的水平，但我们在这项研究中发现的高频率摄入塑料表明长期影响，例如塑料中污染物的吸收可能是全民关注的问题。
Laysan Albatrosses (Phoebastria immutabilis) and Black-footed Albatrosses (P. nigripes) ingest plastic debris, as evidenced by studies showing plastic in the digestive contents of their chicks, but there is little documentation of the frequency and amount of ingested plastics carried in foraging adults. In this study, we quantify plastics among the digestive contents of 18 Laysan Albatrosses and 29 Black-footed Albatrosses collected as by-catch in the North Pacific Ocean. We found ingested plastic in 30 of the 47 birds examined, with Laysan Albatrosses exhibiting a greater frequency of plastic ingestion (83.3% n=18) than Black-footed Albatrosses (51.7% n=29) (X2=4.8, df=1, P=0.03). Though the mass of ingested plastic in both species (mean±SD=0.463g±1.447) was lower than previously noted among albatross chicks, the high frequency of ingested plastic we found in this study suggests that long-term effects, e.g. absorption of contaminants from plastics, may be of concern throughout the population.
