摘要

近年来,在野生动物监测中使用无人驾驶飞行器的情况有所增加,特别是在难以进入的栖息地。我们使用固定翼和四轴飞行器对加拿大维多利亚州城市筑巢的白羽鸥进行了人口普查。我们进行了为期2年的研究,并询问(i)无人机是否代表了我们研究区域屋顶筑巢海鸥的合适调查方法;(ii)自30年前的上次调查以来,维多利亚州的城市海鸥数量有所增加。利用无人机飞越的正交图像,我们估计整个城市的数量比1986年报告的至少增加了三倍(从114对增加到346对),在市中心筑巢的海鸥数量增加了大约十倍。事实证明,无人机是一个很好的平台,可以用来对屋顶筑巢的鸟类进行普查:在我们的数字图像中,很容易就能看到有人筑巢的鸟巢,孵化的鸟类也不会受到无人机的干扰。这种不受干扰的情况可能是由于维多利亚位于机场内;海鸥每天经历几十次水上飞机和直升机飞行,可能已经习惯了空中交通。自20世纪80年代以来,白眉鸥在该地区的自然岛屿栖息地数量大幅减少。我们的研究结果表明,尽管城市屋顶为该物种提供了替代的筑巢栖息地,但当地的海鸥种群并不是简单地从岛屿迁移到该地区的屋顶上。

Evaluating UAV-based techniques to census an urban-nesting gull population on Canada’s Pacific coast
The use of unmanned aerial vehicles, or drones, in wildlife monitoring has increased in recent years, particularly in hard-to-access habitats. We used fixed-wing and quadcopter drones to census an urban-nesting population of Glaucous-winged Gulls in Victoria, Canada. We conducted our study over 2 years and asked whether (i) drones represent a suitable survey method for rooftop-nesting gulls in our study region; and (ii) Victoria’s urban gull population had increased since the last survey >30 years earlier. Using orthomosaic imagery derived from drone overflights, we estimated at least a threefold increase over the 1986 count reported for the entire city (from 114 to 346 pairs), and an approximate tenfold increase in the number of gulls nesting in the downtown core. Drones proved to be an excellent platform from which to census rooftop-nesting birds: occupied nests were readily discernible in our digital imagery, and incubating birds were undisturbed by drones. This lack of disturbance may be due to Victoria’s location in an aerodrome; gulls experience dozens of floatplane and helicopter flights per day and are likely habituated to air traffic. Glaucous-winged Gulls have declined considerably at their natural island colonies in the region since the 1980s. Our results indicate that although urban roofs provide replacement nesting habitat for this species, local gull populations have not simply relocated en masse from islands to rooftops in the region.
