摘要

摘要/ Abstract摘要:研究人员于2022年在加拿大新省奥拉克对尼尔森麻雀(Ammospiza nelsoni, Nelson’s Sparrow)进行了无线电跟踪研究，发现了2例意外捕食事件。在第一个案例中，我们在一个反刍的颗粒中发现了一只无线电标记的尼尔森麻雀的残骸，这可能是来自Asio flammeus(短耳猫头鹰)或Circus hudsonius(北方鹞)。在另一个案例中，我们发现一只成年雌性尼尔森麻雀和她的雏鸟被埋在地下隧道中，可能是被短尾鼬(Mustela erminea)捕食的，这是一种没有记录的尼尔森麻雀捕食者。这些观察有助于更好地了解尼尔森麻雀的捕食行为，并证明了对野生动物进行跟踪研究的间接好处。

Radio Telemetry Reveals Two Cases of Predation on Nelson's Sparrow (Ammospiza nelsoni)

Abstract - During a radio-tracking study of Ammospiza nelsoni (Nelson's Sparrow) in Aulac, NB, Canada, in 2022, we observed 2 unexpected cases of predation. In the first case, we found the remains of a radio-tagged Nelson's Sparrow inside a regurgitated pellet, which presumably was from an Asio flammeus (Short-eared Owl) or a Circus hudsonius (Northern Harrier). In another case, we found an adult female Nelson's Sparrow and her nestlings buried in underground tunnels, likely having been depredated by a Mustela erminea (Short-tailed Weasel), an undocumented predator for Nelson's Sparrow. These observations contribute to greater knowledge of predation of Nelson's Sparrows and demonstrate an indirect benefit of tracking studies on wildlife.

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.
