Project description

This observatory is part of the Vigie Nature network.

The methodology is simple and straightforward: observers who want to participate are randomly assigned a 2×2 km area within a 10 km radius around a location of their choice as well as an alternative area in the event that first area is inaccessible.

Inside the assigned area, the observer needs to set up 10 transects (paths) for counting in a way that is consistent and proportional to the local habitats. He or she should then complete two counts each winter, with an interval of at least four weeks between counts, during the months of December and January. All the birds seen and heard should be noted, and the habitat should be described according to a European classification system that has been adapted for France.

The bird and habitat surveys are repeated every year at the same points and same dates, weather conditions permitting, by the same observer. The national network operates through local coordinating offices which liaise between the national coordination office and the observers. The program protocol is available on the website, along with various information on how to set up the program (including the list of local coordinators to contact to participate).
