SummaryThe Philippines is a global biodiversity hotspot, with a large number of threatened bird species, one of which is the ‘Critically Endangered’ Negros Bleeding-heart Gallicolumba keayi. The aim of this study was to investigate the habitat preference of the Negros Bleeding-heart and undertake species distribution modelling to locate areas of conservation importance based on identified suitable habitat. A survey of 94 point-counts was undertaken and eight camera traps were deployed from May to August 2018 in the Northwest Panay Peninsula Natural Park, Panay, Philippines. Habitat variables (canopy cover, understorey cover, ground cover, elevation, presence of rattan Calamus or Daemonorops spp. and pandan Pandanus sp., tree diameter at breast height, and branching architecture were measured in 5 m-radius quadrats. To identify areas of potentially suitable habitat for the Negros Bleeding-heart, species distribution was modelled in MaxEnt using tree cover and elevation data on Panay and Negros. Using a Generalised Linear Model, Negros Bleeding-heart presence was found to be significantly positively associated with dense understorey cover and dense canopy cover. Species distribution modelling showed that the Northwest Panay Peninsula Natural Park is currently the most suitably located protected area for Negros Bleeding-heart conservation, while protected areas in Negros require further law enforcement. It is imperative that protection is continued in the Northwest Panay Peninsula Natural Park, and more survey effort is needed to identify other critical Negros Bleeding-heart populations, around which deforestation and hunting ban enforcement is strongly recommended.

Negros Bleeding-heart Gallicolumba keayi 喜欢茂密的下层植被和茂密的树冠覆盖，物种分布模型显示几乎没有剩余的合适栖息地

总结菲律宾是全球生物多样性热点地区，有大量受威胁的鸟类，其中之一是“极度濒危”的内格罗斯出血心脏小鸡. 本研究的目的是调查内格罗斯出血心脏的栖息地偏好，并进行物种分布建模，以根据已确定的合适栖息地定位具有保护重要性的区域。2018 年 5 月至 2018 年 8 月，在菲律宾班乃的西北班乃半岛自然公园进行了 94 个点数的调查，并部署了 8 个相机陷阱。栖息地变量（树冠覆盖、下层覆盖、地面覆盖、海拔、藤条的存在菖蒲要么守护神spp. 和班兰露兜树sp.、树高处的树径和分枝结构在 5 米半径样方中测量。为了确定可能适合内格罗斯流血心脏栖息地的区域，在 MaxEnt 中使用 Panay 和 Negros 的树木覆盖和海拔数据对物种分布进行了建模。使用广义线性模型，发现内格罗斯心脏出血与密集的下层覆盖和密集的树冠覆盖显着正相关。物种分布模型显示，西北班乃半岛自然公园是目前最适合内格罗斯心脏保护的保护区，而内格罗斯保护区需要进一步执法。必须继续保护西北班乃半岛自然公园，
