Discovery of two major seabird colonies in Madagascar

Abstract : This paper reports the discovery of the two most important breeding places for seabirds in Madagascar. Nosy Manampaho (east coast, 60 km south east of Antsiranana) holds the largest Sooty Tern Onychoprion fuscata colony in Madagascar (21 800 pairs). The colony is intensively harvested (eggs only), but some regulation occurs. Egg harvest generates important income for the local community, and this revenue is used to employ wardens and authorized egg collectors. As a consequence, the island and its seabird colony are better protected than most seabird places in the country. Nosy Foty (west coast, 30 km to the west of Antsiranana) is in the core area of the Marine National Park of Nosy Hara. It holds an important colony of Crested Terns Thalasseus bergii. Although heavily harvested in the past, the colony is now protected and has increased from fewer than 1000 pairs in July 1997 to 10 840 in July 2008. This colony of Crested Terns is now the most important of Madagascar and of the all Western Indian Ocean. Although ecotourism is not developed yet in the region, such an impressive seabird colony may be used by local authorities to promote the National Park and to increase the number of visitors in the region. Access to the colony should be strictly regulated, however. Our findings are discussed in the context of sustainable use of biodiversity in poverty alleviation in Madagascar.
