Abstract

Abstract - Haliaeetus leucocephalus (Bald Eagle) is a species that congregates in communal roosting sites during the non-breeding periods of its life cycle. Wildlife agencies are directed to protect roosts, but their nocturnal usage and remote locations make them challenging to identify and monitor. We remotely identified and ground-truthed roost sites using satellite telemetry data. We delineated 13 confirmed roosts and another 34 suspected roosts. Volunteers observed 12 roosts with ground surveys and confirmed 92% were in use by eagles during their first observation. These results suggest use of eagle-tracking data to remotely identify communal roosts is a promising tool for finding and protecting eagle roosting habitat. This method can be complemented with volunteer surveys to confirm ongoing roost use.

提高对远程划定的秃鹰栖息地的信心，触发国家机构栖息地保护

摘要白头海雕(halaliaeetus leucocephalus)是一种在其生命周期的非繁殖期聚集在公共栖息地点的物种。野生动物机构被指示保护栖息地，但它们的夜间活动和偏远的位置使它们难以识别和监测。我们使用卫星遥测数据远程识别和地面核实栖息地。我们圈定了13个已确认的栖息地和34个疑似栖息地。志愿者通过地面调查观察了12个栖息地，并在第一次观察时确认92%的栖息地被老鹰使用。这些结果表明，利用鹰跟踪数据远程识别公共栖息地是发现和保护鹰栖息栖息地的一种很有前途的工具。这种方法可以与志愿者调查相辅相成，以确认正在进行的栖息地使用。

期刊介绍： The Northeastern Naturalist covers all aspects of the natural history sciences of terrestrial, freshwater, and marine organisms and the environments of the northeastern portion of North America, roughly bounded from Virginia to Missouri, north to Minnesota and Nunavut, east to Newfoundland, and south back to Virginia. Manuscripts based on field studies outside of this region that provide information on species within this region may be considered at the Editor’s discretion. The journal welcomes manuscripts based on observations and research focused on the biology of terrestrial, freshwater, and marine organisms and communities as it relates to their life histories and their function within, use of, and adaptation to the environment and the habitats in which they are found, as well as on the ecology and conservation of species and habitats. Such studies may encompass measurements, surveys, and/or experiments in the field, under lab conditions, or utilizing museum and herbarium specimens. Subject areas include, but are not limited to, anatomy, behavior, biogeography, biology, conservation, evolution, ecology, genetics, parasitology, physiology, population biology, and taxonomy. Strict lab, modeling, and simulation studies on natural history aspects of the region, without any field component, will be considered for publication as long as the research has direct and clear significance to field naturalists and the manuscript discusses these implications.
