Summary

In 1987, the 13 departments that comprised the South Western Hunting Region grouped up to launch a wide-reaching study on the Pigeon (Columba palombus). For the study of migration in the plains, the basic data were provided by a network of "hunters/observers". The projects undertaken have allowed us to determine three migration corridors in the South West and establish a migration index that would allow us to continue and compare the intensity of migration every year. Thus, after an exceptional year in 1988, migration decreased (1991) and increased (1996). The global trend over the last eleven years is now closer to stability than to a drop in migrant indexes.
