Abstract

Abstract - I observed mobbing of Glaucomys volans (Southern Flying Squirrel), upon removal and release from nesting boxes designed for them, by various bird species (1–9 total individual birds) on 33 occasions during winter surveys for the squirrels in southeast Ohio. I observed instances of mobbing by 1–3 species of primary and/or secondary cavity-nesting songbirds and woodpeckers. Mobbing behavior included flights within 1–2 m of a flying squirrel briefly positioned on a tree trunk as well as vocalizations. Mobbing episodes lasted 5–180 seconds, which largely depended on the amount of time a flying squirrel remained visible before retreating into a natural cavity. In light of the mobbing response reported here, perhaps more consideration should be given to the potential impacts that Southern Flying Squirrels may have on bird communities.

穴巢鸟捕食南方松鼠的冬季观测

摘要/ Abstract摘要:在俄亥俄州东南部的松鼠冬季调查中，我观察到33次不同鸟类(1-9只)在将南方鼯鼠从为它们设计的巢箱中移出或释放时，对它们的攻击。我观察到1-3种主要和/或次要洞巢鸣禽和啄木鸟的围攻实例。暴走行为包括在1-2米范围内飞行的飞鼠短暂地定位在树干上，并发出声音。围攻事件持续5-180秒，这在很大程度上取决于一只鼯鼠在撤退到自然洞穴之前保持可见的时间。鉴于这里报道的蜂拥而至的反应，也许应该更多地考虑南方鼯鼠对鸟类群落的潜在影响。

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.
