Anthropogenic disturbances are a major concern for the welfare and conservation of wildlife. We recorded heart rate and body temperature of 20 free-living greylag geese in response to a major regularly re-occurring anthropogenic disturbance-New Year's Eve fireworks. Heart rate and body temperature were significantly higher in the first and second hour of the new year, compared with the same hour on the 31st of December, the average during December and the average during January. Heart rate and body temperature was not significantly affected by sex or age. From 0200 to 0300 onwards, 1st of January heart rates did not significantly differ from the other periods; however, body temperatures were significantly increased until 0300-0400. From 0400 to 0500, heart rate was not affected by any of the investigated factors, whereas body temperature was significantly increased on the 1st of January compared with the 31st of December and the December average but not compared with the January average. To conclude, our results show that New Year's Eve fireworks cause a substantial physiological response, indicative of a stress response in greylag geese, which is costly in terms of energy expenditure.
人为干扰是野生动物福祉和保护的主要关注点。我们记录了20只自由生活的灰雁在面对一种主要的定期反复出现的人为干扰——新年前夜烟花时的心率和体温。与12月31日同一时刻、12月的平均水平以及1月的平均水平相比，新年的第一个小时和第二个小时心率和体温显著更高。心率和体温不受性别或年龄的显著影响。从1月1日02:00到03:00起，心率与其他时段没有显著差异；然而，体温一直显著升高直到0:30 - 04:00。从04:00到05:00，心率不受任何所研究因素的影响，而与12月31日及12月平均水平相比，1月1日体温显著升高，但与1月平均水平相比则没有。总之，我们的结果表明新年前夜烟花会引发显著的生理反应，这表明灰雁出现了应激反应，而这在能量消耗方面代价高昂。
