L’urbanisation des villes altere la naturalite des espaces qu’elles occupent. Cette situation impacte surement la diversite et la distribution de la faune aviaire. Ce travail, le premier du genre dans Niamey, a pour objectif d’apprecier la diversite et la distribution de l’avifaune en lien avec les differents types d’habitations de la ville de Niamey et de sa zone humide. La methode consiste a denombrer les oiseaux sur des transects qui passent dans chaque commune et sur le point fixe choisi sur le Fleuve. Les denombrements se font de 7 h a 9 h30 et de 16 h30 a 18 h30 sur l’ensemble des sites. Cela a permis de recenser 38 especes pour toute la ville de Niamey avec respectivement 18, 22, 18 et 21 especes sur les transect 1, 2, 3 et le fleuve.. Les resultats montrent que les especes les plus ubiquistes sur les trois transects sont : Streptopelia senegalensis , Lamprotornis purpureus , Bubulcus ibis . Les moins observees sont: Milvus migrans , Merops orientalis , Sylvietta brachyura , Nilaus afer , Uraeginthus bengalus . Sur le fleuve, les plus ubiquistes sont : Bubulcus ibis et Ardea cinerea et les moins observees sont : Ardea alba , Ardeola ralloides , Actophilornis africana , Tringa nebularia et Melanitta nigra . © 2018 International Formulae Group.

This situation surely impacts the diversity and distribution of bird fauna. This work, the first of its kind in Niamey, aims to appreciate the diversity and distribution of birdlife in relation to the different types of housing in the city of Niamey and its wetland. The method consists in counting the birds on transects which pass in each commune and on the chosen fixed point on the river. Counts are from 7am to 9.30 am and from 4.30 pm to 6.30 pm on all sites. This allowed to identify 38 species for the whole city of Niamey with respectively 18, 22, 18 and 21 species on transects 1, 2, 3 and the river. The results show that the most ubiquitous species on the three transects are : Streptopelia senegalensis , Lamprotornis purpureus , Bubulcus ibis . The least observed are: Milvus migrans , Merops orientalis , Sylvietta brachyura , Nilaus afer , Uraeginthus bengalus . On the river, the most ubiquitous are: Bubulcus ibis and Ardea cinerea and the least observed are: Ardea alba, Ardeola ralloides , Actophilornis africana , Tringa nebularia and Melanitta nigra . © 2018 International Formulae Group.
