This study examines the occurrence and underlying factors of onshore strandings of two species of seabirds breeding in Newfoundland and Labrador, Canada. Atlantic Puffins (Fratercula arctica) are found stranded in coastal communities bordering the Witless Bay Ecological Reserve in artificially lit areas. Between 2011 and 2020, 3845 recently fledged puffins were found during nightly searches. Counts of puffins found per night were related to the phase of the moon, with the fewest birds found around the full moon. Mean annual body mass of pufflings was positively associated with annual recovery rates, providing a non-intrusive approach to monitor inter-annual productivity at the colony. Using two approaches to estimate population impacts of strandings, we estimate that < 0.2% of fledging chicks were attracted to lights emitted from coastal communities. Despite bordering two of the largest Leach's Storm-Petrel (Oceanodroma leucorhoa) colonies in Newfoundland, this species was rarely observed stranded in the Witless Bay area. Rather, most of the 1903 stranded storm-petrels reported in 2018 and 2019 were found on industrial properties bordering, or inland of, Conception Bay, at minimal distances of 25 km inland from the Witless Bay Ecological Reserve. Most storm-petrels were recently fledged juveniles. Strandings were less likely to occur around the full moon. Neither strong nor persistent winds were observed during nights of large stranding events, however, these nights tended to have winds coming from the north, suggesting that stranded storm-petrels fledged from Baccalieu Island, located at the mouth of Conception Bay and hosting the largest colony in the world. Stronger mitigation measures to avoid and minimize light emittance, as well as research investigating light characteristics to reduce attraction, are urgently needed to decrease unnecessary strandings, particularly for the Leach's Storm-Petrel, recently assessed as Threatened by the Committee on the Status of Endangered Wildlife in Canada.

陆上光污染对加拿大纽芬兰和拉布拉多的两种巢穴海鸟的影响

这项研究调查了在加拿大纽芬兰和拉布拉多繁殖的两种海鸟在岸上搁浅的发生及其潜在因素。发现大西洋海雀（Fratercula arctica）滞留在与人工照明地区的机智湾生态保护区接壤的沿海社区。在2011年至2020年之间，每晚进行搜索时发现了3845个最近出现过的海雀。每晚发现的海雀数量与月相有关，在满月附近发现的鸟类最少。膨化的平均年体重与年恢复率呈正相关，提供了一种非侵入性的方法来监测菌落的年间生产力。使用两种方法来估计搁浅对人口的影响，我们估计<0。2％的雏鸡被沿海社区发出的光所吸引。尽管在纽芬兰有两个最大的浸出雷德海豹（Oceanodroma leucorhoa）殖民地，但该物种很少在无烟湾地区滞留。相反，2018年和2019年报告的1903条困困海燕大部分都在与构想湾接壤或内陆的工业地产上发现，距威特莱斯湾生态保护区内陆至少25公里。大多数风暴海燕是最近成年的幼体。满月附近不太可能发生搁浅。在大型搁浅事件的夜晚，既没有观察到强风也没有持续的风，但是，这些夜晚往往有风从北方吹来，这表明搁浅的海燕从巴卡里乌岛逃离了，位于构想湾（Conception Bay）的入口，是世界上最大的殖民地。为减少不必要的搁浅，迫切需要采取更强有力的缓解措施来避免和最大程度地减少光的发射，并研究发光特性以减少不必要的搁浅，特别是对于最近被濒危野生动植物状况委员会评估为受到威胁的“浸出物的风暴海燕”而言。在加拿大。
