For many territorial hummingbirds, habitat use is influenced primarily by the interaction between resource acquisition and non‐foraging behaviors such as territory advertisement and defense. Previous research has highlighted the importance of foraging‐associated habitat features like resource density and distribution in determining the space‐use patterns of hummingbirds. Less is known, however, about how habitat selection associated with non‐foraging behaviors influences space use by territorial species. We used radio telemetry to examine patterns of territorial space use by Shining Sunbeams (Aglaeactis cupripennis) in high Andean montane forests near Manu National Park, Peru, and Bosque Comunal “El Carmen” near Chordeleg, Ecuador. We quantified within‐territory habitat characteristics related to resource acquisition and non‐foraging behaviors such as territory advertisement and defense. We found that Shining Sunbeams showed high use of core areas in territories where foraging effort was relatively low. We found no relationship, however, between the position of core areas and habitat characteristics associated with territory defense, predator avoidance, or other non‐foraging behaviors. We also found no relationship between use of non‐core areas and habitat use based on resource acquisition. Thus, patterns of territorial space use by Shining Sunbeams may be characterized by core areas not determined by foraging behavior. Further studies examining territorial behaviors and the influence of intrusion pressure will help identify the underlying determinants of territory space use by this and other species of Andean hummingbirds.

灿烂的阳光（Aglaeactis cupripennis），热带山地蜂鸟使用的领土空间模式

对于许多领土蜂鸟而言，栖息地的使用主要受到资源获取与非觅食行为（例如区域广告和防御）之间相互作用的影响。先前的研究强调了觅食相关的栖息地特征（如资源密度和分布）在确定蜂鸟的空间使用方式中的重要性。然而，关于与非觅食行为相关的栖息地选择如何影响领土物种的空间利用的知之甚少。我们使用无线电遥测技术检查了“闪亮的阳光”（Aglaeactis cupripennis）位于秘鲁马努国家公园附近的安第斯山脉高山森林中，以及厄瓜多尔乔德莱格附近的博斯克社区“ El Carmen”。我们量化了与资源获取和非觅食行为（例如区域广告和防御）相关的区域内栖息地特征。我们发现，“光亮的阳光”在觅食工作量相对较低的地区显示出对核心区域的大量使用。但是，我们发现核心区域的位置与与领土防御，掠食者躲避或其他非觅食行为相关的栖息地特征之间没有关系。我们还发现基于资源获取的非核心区域的使用与栖息地的使用之间没有关系。因此，灿烂的阳光使用的领土空间模式的特征可能在于核心区域，该核心区域不是由觅食行为决定的。
