Objectifs : cette etude vise a actualiser les connaissances sur l’avifaune de la zone humide de Grand- Bassam et a determiner les variations annuelles du peuplement d’Oiseaux. Methodologie et resultats : l’avifaune a ete inventoriee de janvier 2011 a fevrier 2013 par la methode des transects itinerants avec des points d’arret de 15 minutes aux endroits appropries. Au total, 218 especes appartenant a 51 familles et 17 ordres ont ete identifiees. La presente etude revele 49 especes nouvellement observees dans la zone humide de Grand-Bassam. Le peuplement d’Oiseaux rencontre renferme un grand nombre d’individus dont le pic annuel est atteint en juillet. Ce peuplement est domine par les populations de tisserin gendarme ( Ploceus cucullatus ), de travailleur a tete rouge ( Quelea erythrops ) et de capucin nonnette ( Spermestes cucullata ). Conclusion et application : cette etude contribue a une meilleure connaissance de l’avifaune de la zone humide de Grand-Bassam et fournit des donnees preliminaires sur l’importance numerique des differentes especes inventoriees. Face a une anthropisation de plus en plus prononcee de la zone humide, liee au developpement de la ville et aux activites agricoles, ces resultats serviront de base scientifique a l’etablissement d’un systeme de gestion durable de l’avifaune dans les rizicultures. Mots cles : Oiseaux, Biodiversite, Dynamique du peuplement, Zone humide Riziculture, Grand- Bassam. Dynamics of birds’ community, of international importance in the rice fields and surrounding areas in the Grand-Bassam wetland. Objectives : This study aims to update the knowledge on birds’ community of the Grand-Bassam wetland and it annual variation. Methodology and Results : Birds were surveyed from January 2011 to February 2013 by the method of line transects with a 15 minutes points count in the appropriated places. A total 218 species belonging to 51 families of 17 orders were identified. The study found 49 newly observed species in the Grand- Bassam Ramsar site. The birds’ community is rich of an important number of individuals which maximum is in July. This bird’s community is dominated by populations of Village Weaver( Ploceus cucullatus ),, Red-headed Quelea ( Quelea erythrops ) and Bronze Mannikin ( Spermestes cucullata ).. Conclusion and application : This study has contributed to a better knowledge of the avifauna of Grand- Bassam Ramsar site and provides preliminary data on the size of the different species. Facing a more pronounced anthropisation due to the development of the city and farming, these results can served as a first scientific basis for the establishment of a sustainable management of the avifauna in ricefields.
