New study to help save the world’s most spectacular hummingbird – Other rare birds to benefit

August 2009. A new report on one of the world's bird biodiversity hotspots in Peru finds that most of the species at greatest risk there currently have little or no protected habitat. Conservation groups now plan to use the report to guide land protection efforts in the region. The study was produced by a coalition of conservationists working with the Peruvian conservation group Asociación Ecosystemas Andinos (ECOAN) and American Bird Conservancy, as well as independent biologists.

"American Bird Conservancy and ECOAN are committed to conserving threatened species and their habitats in Peru, including the Marvelous Spatuletail, an amazing hummingbird found only in Peru, and the rare Long-whiskered Owlet," said study co-author Hugo Arnal, American Bird Conservancy's Director of International Sustainable Conservation. "This latest study will help guide future conservation work in the Marañon region to ensure the best results can be achieved with critical conservation dollars."

0.1% of critical area is protected
"This work highlights the critical need to protect the Marañon-Alto Mayo Conservation Corridor," said ECOAN's Tino Aucca, one of the study authors. "Even though the region is considered a high conservation priority, barely 0.1% of it is actually protected."

26 birds endemic to Peru
This new study identified 64 bird species of conservation importance in the Marañon, with a subset of 28 bird species of the highest conservation priority. Twenty-six of these are endemic to Peru, and four have been identified by the Alliance for Zero Extinction (AZE) as restricted to single small areas, the protection of which is essential if the species are to survive.

Using information on the known locations and the most recent vegetation maps, the researchers projected the potential range for these highest priority species. Based on these ranges, from one to seven potential conservation areas for each species were identified. These individual areas were then overlain to select the ten highest priority areas which are being proposed for a wide array of conservation strategies, from strict protected area status to sustainable conservation programs, and community owned nature reserves.

"The study not only sheds light on the problem of lack of protection for the key bird species and their habitats in the Marañon, it also provides a way forward by scientifically identifying ten priority areas for conservation," said Arnal. "This will provide the greatest conservation return for our investment in the area."
