Biologie et génétique des populations du Pigeon à couronne blanche, Patagioenas leucocephala : applications à la gestion et la conservation de l'espèce
Le projet vise à apporter des éclaircissements sur l’écologie et la dynamique démographique des deux espèces à l’échelle régionale et proposer une méthode de suivi de leurs populations
The White-crowned Pigeon and the Scaly-naped Pigeon are two Caribbean-endemic species of colombids much appreciated by local hunters and of patrimonial interest. They are on the IUCN Red List of Endangered Species ("Near Threatened" and "Least Concern" status, respectively). However, across the French Antilles, their conservation status have been considered as higher. The White-crowned Pigeon has thus been reclassified as “Endangered” and “Vulnerable”, respectively in Guadeloupe and Martinique, while the Scaly-naped Pigeon is considered “Near Threatened” in Martinique. These frugivorous birds consume the fruits of several trees and thus play an important role in the dissemination of seeds and regeneration of tropical Caribbean tree communities. The flight ability and the vagrancy of these species also induce large-scale seed dispersal. Despite their important role, data on the ecology of these two species and the demography of their populations, both on a large scale and in the French Antilles, are still limited.
The project aims at documenting the ecology and demographic dynamics of the two species on a regional scale and to propose a method for monitoring their populations.
