Distribution des passereaux dans les biotopes forestiers et de substitution forestiers au Sud-Bénin

The passerine constitutes a key group of forest birds on which it is necessary to found for the followup of the avian and the dynamics of the landscape. Those of the forest surroundings and substitution (plantation and fallow) of the south of Benin are counted by the technique of point of monitoring of 20 minutes through 45 stations of 2003 to 2007. Their distribution done by Analysis of the Multiple Correspondences and Ascending Hierarchical Classification revealed a clear opposition between the forest bird communities and those of the plantations and fallows. Thus, on the set of the prospected stations, the avian population is structured well and this structure can be put in relation with the gradient of vegetation prospected. Groups of indicatory birds of the different biotopes in presence have also been put in inscription as follows: avian species wooded surrounding ubiquities; avian species distinctly ubiquities or " versatile " in all surroundings; birds of the wooded surroundings of substitution (plantation and old fallow or under - plantation); birds of the non wooded surroundings of substitution (fallows bushy or young); birds typical of humid forests. All the same the non-existence of difference of avian composition is noted between fallow and plantation. In the same way group of passerine doesn’t discriminating in the plantations of Elaeis guineensis and Tectonia grandis that behave as fallows evolved whereas the plantations of Cocos nucifera are individualized well.
