Abstract
Summary

From mid-September 1993 to February 1994 avian species were inventoried at eight sites selected to sample the major biogeographic areas and threatened habitats of Masoala Peninsula of north-eastern Madagascar. The sites ranged from 10 to 1100 m elevation. Three forest types were inventoried: six sites included primary lowland rainforest (0–700 m), one site was characterized as moist montane forest (above 700 m), and one site was classified as littoral forest. Bird species and distribution were sampled using point counts and line transects, tree observations and opportunistic sightings; 85 avian species were detected. Line transects were the most productive technique for number of species detected. Twenty-four detected species were shared by all inventory sites. Six threatened and six near-threatened species were observed with notes on their ecology and behaviour. One endangered species, the Madagascar Serpent-eagle Eutriorchis astur, was first observed along a forest edge and then sighted several times at forest interior sites, suggesting that this secretive endangered raptor is not as rare as previously thought. Another species of indeterminate status, the Madagascar Red Owl Tyto soumagnei, was discovered by two villagers near one inventory site in modified habitat. Several rare and near-threatened species were found to be common throughout Masoala Peninsula: Scaly Ground-roller Brachypteracias squamiger, Short-legged Ground-roller B. leptosomus, Red-breasted Coua Cona serriana, Brown Mesite Mesitornis unicolor, Helmet Vanga Euryceros prcvostii, Bernier's Vanga Oriolia bernieri and Rand's Warbler Randia pseudozosterops; the last was only found along pristine riverine habitat. Three species were detected only at the high elevation montane forest: Grey-crowned Greenbul Phyllastrephus cinereiceps, Forest Rock-thrush Pseudocossyphus sharpei and Madagascar Brush-warbler Nesillas typica. Forest degradation from subsistence agriculture, shifting cultivation and fuelwood collecting threatens natural resources and biodiversity but conservation and development efforts can provide alternatives to meet the needs of the local people.

Depuis la moitié du mois de septembre 1993 jusqu'au février 1994, nous avons inventorié la communauté avienne dans huit sites représentant la grande partie des habitats naturels de la Presqu'île de Masoala, Nord-Est de Madagascar. Ces sites ont des altitudes comprises entre 10 et 1100 m. Trois types de forêt ont été inventoriés: six sites de forêt primaire de basse altitude (0–700 m), un site considéré comme forêt humide de montagne (plus de 700 m), et le dernier classé comme for^t littorale. L'échantillonage était fait par point d'écoute et ligne de transect. Certains grands arbres ont été utilisés comme poste d'observation. Quatre-vingts cinq espèces d'oiseaux étaient détectées. Vingt quatre espèces sont communes aux sites inventoriés. Six espèces classées comme menacé et six autres en train de l'être sont observées avec des notes sur leur écologie et comportement. Une espèce en danger, l'Aigle serpentaire Eutriorchis astur, était observée pour la première fois le long d'une bordure forestière et puis vue plusieurs fois en pleine forèt. Ce qui suggère que cette espèce en danger et trèsdiscrète n'est pas très rare comme on a toujours pensé. Une autre espèce de statut indéterminé, l'Effraie de Soumagne Tyto soumagnei était découverte par deux villageois près d'un site d'inventaire dans un habitat dégradé. Quelques espèces rares et en train d'être menacées semblaient communes dans toute la Presqu'île de Masoala: Rollier terrestre écailleux Brachyptcracias squamiger, Rollier terrestre leptosome B. leptosomus, Coua de Serre Couci scrriana, Mésite unicolore Mesitornis unicolor, Eurycère de Prévost Euryceros prevostii, Oriolie de Bernier Oriolia bernieri et la Fauvette de Rand Randia pseudozosterops. Cette dernière se trouve seulement dans les habitats longeant les cours d'eau. Trois espèces sont seulement observées dans une forêt de haute altitude de montagne: Bulbul a tête grise Phyllastrepluis cinereiceps, Merle de roche de forêt Pseudocossyphus sharpei et la Fauvette de Madagascar Nesillas typica. La dégradation forestière causée par le besoin de surface cultivable, la culture itinérante et la collecte de bois de chauffe, menacent les ressources naturelles et la biodiversité du milieu. Seulement, la conservation en parallèle avec des efforts de développement peut fournir une alternative aux besoins de la population locale. Ceci est parmi les objectifs du Projet Masoala; cherchant des alternatives pour la population locale en même temps que la création d'un Pare National qui pourrait protéger une grande partie de bloc forestier de basse altitude de Madagascar, plus de 210.000 hectares.
