A new study mapping the likely nesting habitats of the iconic Philippine eagle in its main stronghold warns that the threat of habitat loss — a key driver of its disappearance across much of its range — still looms large for the critically endangered species. The study, published in Bird Conservation International, shows that approved mining concessions overlap with 41% of highly suitable nesting habitat and 65% of its core areas in eastern Mindanao, the Philippines’ southernmost and second-largest island. Only about 35% of the highly suitable habitat identified across the Eastern Mindanao Biodiversity Corridor falls within protected areas. Indigenous ancestral domains separately overlap with 65% of core high-quality nesting habitat. (The figures do not necessarily represent the same areas, the study notes.) “This study turns nearly four decades of field observations, nest records, GPS tracking and satellite information into something people can actually use,” study co-author Christopher J.W. McClure, vice president for global science at U.S.-based NGO The Peregrine Fund, said in a Sept. 24 statement issued by the Philippine Eagle Foundation. “It helps us see where surveys and safeguards are needed most before important habitat is changed,” McClure added. Juan Carlos Gonzalez, an ornithologist and curator for birds at the Museum of Natural History at the University of the Philippines Los Baños, who wasn’t involved in the research, said the findings are concerning because Philippine eagles (Pithecophaga jefferyi) already have limited suitable habitat inside protected areas and also persist in Indigenous-managed forests. “Both represent the last stronghold for…This article was originally published on Mongabay
