L’écologie des tourterelles nicheurs dans la région de Ghardaïa

Abstract

The study of the nesting strategy of two species of turtledove streptopelia senegalensis and Turkish turtledove streptopelia decaocto ”nesting in the city of Ghardaia was carried out by regular monitoring over three months (December - March) in three different sites (Hospital , Hotel El Djanoub and cited Bounoura) whose objective is to know do these two species have the same nesting behavior or not towards the same habitat? The method used is the systematic search for nests, which consists in systematically searching all the vegetation once or twice a week in each of the three sites. The height of the nests, the distance from the trunk and the nearest water point were measured by a laser meter The results show that the height of the nests of mesh doves is higher 8.50 ± 2.47 m than those of Turkish doves 6.83 ± 2.82m, while the orientation preferred by Streptopelia senegalensis is towards the North. west, unlike streptopelia decaocto, the preferable orientation is east (north-east and south-east) and finally the installation of the nests of two species is 80% on the trunk
