摘要

摘要世界各地许多人的文化和传统中都有烟花庆祝活动,但它们对自然栖息地鸟类种群的影响尚不清楚。2019年3月和4月,对墨西哥祖潘戈泻湖两次烟花庆典相关的鸟类物种丰富度和丰度变化进行了评估。在泻湖边缘建立了六个点计数,以记录鸟类物种的丰富程度和事件发生之前,期间和之后的丰度。此外,在每个点计数时测量噪声水平。共观测到鸟类80种,其中水生49种。最丰富的是红鸭(Oxyura jamaicensis)和威尔逊Phalaropus tricolor)。物种丰富度和丰度值随事件发生天数的增加而显著降低,噪声水平增加。此外,这个自然保护区的基础噪音水平(平均= 54.80 dB)被认为很高。结果表明,高影响的人类庆祝活动对鸟类产生了负面影响,这些活动应在区域、国家和全球重要的鸟类保护区(如Zumpango泻湖)受到限制或限制。

Effect of Firework Festivities on Bird Richness and Abundance at a Natural Protected Wetland in Central Mexico
Abstract. Firework festivities have been present in the culture and traditions of many human populations around the world, however their effects on bird populations in natural habitats are not well understood. Changes in bird species richness and abundance related to two firework festivities at the lagoon of Zumpango, Mexico, were evaluated in March and April of 2019. Six point counts were established at the edge of the lagoon to record bird species richness and abundance before, during, and after the events. Additionally, noise levels were measured at each point-count. In total, 80 bird species were observed, including 49 aquatic species. The most abundant were Ruddy Duck (Oxyura jamaicensis) and Wilson's Phalarope (Phalaropus tricolor). The values of species richness and abundance significantly decreased the days when the events took place, while noise levels increased. Furthermore, basal noise levels (mean = 54.80 dB) are considered high for this natural protected area. Results show that high impact human festivities have negative consequences for birds, and these activities should be limited or restricted in regional, national, and globally important bird conservation areas such as the lagoon of Zumpango.
