摘要
定位穴居或缝隙栖息动物的繁殖地或避难地是一项艰巨的任务,尤其是对于隐蔽和神秘的物种。在此,我们总结了在美国加利福尼亚州法拉隆群岛国家野生动物保护区法拉隆岛东南部使用射频识别(RFID)技术定位灰海燕(Hydrobates homochroa)筑巢地点的工作。从 2017 年到 2019 年的三个繁殖季节,我们在雾网捕获的风暴海燕身上共部署了 799 个 RFID 标签。然后,我们尝试在全岛合适的筑巢栖息地重新安置标签上的鸟类。在三个不同的繁殖季节中,我们采用了被动和主动搜索策略,使用固定 RFID 阅读器进行被动搜索时,我们最成功地找到了风暴海燕的巢穴,尽管探测率很低。使用固定式阅读器时,我们平均为 3.1% 的被标记个体找到了可能的巢穴,而使用主动搜索方法时则没有发现任何个体。我们认为,虽然固定式 RFID 阅读器比主动式方法更成功,但我们不能推荐使用这种方法来定位风暴海燕的巢穴,因为这种方法需要耗费大量人力,而且成功率很低。
Limited success of radio frequency identification technology in locating nests of a crevice-nesting seabird, the ashy storm-petrel
Locating the breeding or refuge sites of burrowing or crevice-dwelling animals is a difficult undertaking, particularly for cryptic and secretive species. Here, we summarize our efforts to use Radio Frequency Identification (RFID) technology to locate nesting sites of ashy storm-petrels Hydrobates homochroa on Southeast Farallon Island, Farallon Islands National Wildlife Refuge, California, USA. We deployed a total of 799 RFID tags on storm-petrels captured in mist nets across three breeding seasons from 2017 to 2019. We then attempted to relocate tagged birds in suitable nesting habitat across the island. We employed both passive and active searching strategies over the course of three different breeding seasons and had the most success finding storm-petrel nests using passive searching with stationary RFID readers, although detection rates were low. We found probable nests for an average of 3.1% of tagged individuals with stationary readers and no individuals with an active search method. We suggest that while stationary RFID readers were more successful than active methods, we cannot recommend the method for locating nesting storm-petrels because of the labor involved and low success rate.
期刊介绍:
Journal of Fish and Wildlife Management encourages submission of original, high quality, English-language scientific papers on the practical application and integration of science to conservation and management of native North American fish, wildlife, plants and their habitats in the following categories: Articles, Notes, Surveys and Issues and Perspectives. Papers that do not relate directly to native North American fish, wildlife plants or their habitats may be considered if they highlight species that are closely related to, or conservation issues that are germane to, those in North America.
