无人机系统在野生动物生物学中的应用十分广泛。使用配备适当传感器的无人机进行调查、识别和测量，现在可以添加到监测动物的技术套件中。在这里，我们详细介绍了我们使用无人机从海豹群中获取详细信息的经验，这些信息很难从陆地上观察到。在过去的两年中，在苏格兰的一些地点，使用一系列不同的平台和成像系统进行了调查灰海豹和斑海豹的试验飞行，取得了不同程度的成功。最佳性能的无人机系统由现场、现场情况和所需数据决定。目前，我们的系统通常允许从图像中获得相对丰度、物种、年龄和个体身份，也可以获得身体尺寸的测量，但需要改进。然而，无人机对目标物种的影响也可能是可变的，应该密切监测。我们发现对无人机飞行的不同反应，可能与动物先前受到干扰的经历有关。
Wildlife biology applications of unmanned aerial systems (UAS) are extensive. Survey, identification, and measurement using UAS equipped with appropriate sensors can now be added to the suite of techniques available for monitoring animals - here we detail our experiences in using UAS to obtain detailed information from groups of seals, which can be difficult to observe from land. Trial flights to survey gray and harbor seals using a range of different platforms and imaging systems have been carried out with varying success at a number of sites in Scotland over the last two years. The best performing UAS system was determined by site, field situation, and the data required. Our systems routinely allow relative abundance, species, age-class, and individual identity to be obtained from images currently, with measures of body size also obtainable but open to refinement. However, the impacts of UAS on target species can also be variable and should be monitored closely. We found variable responses to UAS flights, possibly related to the animals' experience of previous disturbance.
