Abstract: Conservation of biodiversity is more than ever a topical concern. The Fifteenth Sustainable Development Goals (SDOs) underscores this. However, in recent years, it has suffered enormous effects that bear witness to regressive measures. This study carried out in a part of the Niger River valley known as the "Bird Islands" has made it possible to assess diversity and to list the pressures to which this diversity is subjected. The methodological approach used is simple stratified sampling (SSS) preceded by the memorization of bird songs carried out over 3 consecutive years. This was followed by the processing and analysis of the data collected in the riparian villages. About fifty species in 17 families were counted with the Shannon index (H') which varies from 1.6 to 3.8 depending on the localities. Following the surveys conducted among the populations, 42 % of our respondents think that agricultural practices are the major problems that do not contribute to the sustainability of the site, and 35 % think that it is rather the uncontrolled sampling. Moreover, the pressures identified are mainly linked to demographic growth, poverty and the inexistence of a firm local policy for the conservation and development of natural resources. Suggestions are made for the protection, safeguarding and integration of this site into the development policies of the commune.
