Abstract

Hawaiian avifaunal communities have suffered irrevocable harm and significant threats remain for extant species. It is increasingly important to monitor and document bird density to improve our understanding of how remaining species respond to changing climate and emergent stressors. In this paper, we report annual densities (2003–2020) of two native and four non-native forest bird species in a region of Hawaiʻi Island lacking previous estimates. We estimated long-term population trends and short-term trajectories within a Bayesian framework. Our findings support previous studies that demonstrated the negative impact of ungulate browsing on forest bird habitat. We also note a detection of the Japanese Bush Warbler (Cettia diphone), a recently documented non-native species. The forest bird population trends presented here fill a regional gap and help extend the understanding of bird populations on Hawaiʻi Island.

夏威夷波哈库洛亚训练区美国陆军驻军森林鸟类种群趋势建模

夏威夷鸟类群落已经遭受了不可挽回的伤害，现存物种仍然面临着巨大的威胁。对鸟类密度进行监测和记录，以提高我们对剩余物种如何应对气候变化和新出现的压力因素的认识，变得越来越重要。在本文中，我们报告了夏威夷大岛一个地区的两种本地和四种非本地森林鸟类的年度密度（2003-2020 年）。我们在贝叶斯框架内估计了长期种群趋势和短期轨迹。我们的研究结果支持了之前的研究，这些研究证明了有蹄类动物的啃食对森林鸟类栖息地的负面影响。我们还发现了日本沼泽莺（Cettia diphone），这是最近记录在案的一种非本地物种。本文介绍的森林鸟类种群趋势填补了一个地区空白，有助于扩展对夏威夷岛鸟类种群的了解。

期刊介绍： Avian Conservation and Ecology is an open-access, fully electronic scientific journal, sponsored by the Society of Canadian Ornithologists and Birds Canada. We publish papers that are scientifically rigorous and relevant to the bird conservation community in a cost-effective electronic approach that makes them freely available to scientists and the public in real-time. ACE is a fully indexed ISSN journal that welcomes contributions from scientists all over the world. While the name of the journal implies a publication niche of conservation AND ecology, we think the theme of conservation THROUGH ecology provides a better sense of our purpose. As such, we are particularly interested in contributions that use a scientifically sound and rigorous approach to the achievement of avian conservation as revealed through insights into ecological principles and processes. Papers are expected to fall along a continuum of pure conservation and management at one end to more pure ecology at the other but our emphasis will be on those contributions with direct relevance to conservation objectives.
