This dataset describes bird observations performed along the Drugeon river, France from 2006 to 2019. ' Carte.jpg ' Map of the study area. The box shows the location of the Bannans and the Sainte-Colombe transects. Village locations and the route of the river have been taken from 'BD Carto ', kindly provided for research by the National Geographical Institute, and modified on the basis of field observations. ' Mat sup 1 transects Drugeon synthèse_Zenodo.xlsx ' since September 2006, two transects were carried out four times a fortnight,on foot in the early morning. All identified birds, by sight or by ear, were noted with special care to avoid double counting. The two transects are located in the downstream part of the Drugeon valley. The Bannans transect starts from the Drugeon diversion upstream from the Bannans flour mill and runs along the river downstream to the place called Mitray, with a lateral extension to the En Vau-Les-Aigues marsh located partly in the La Rivière-Drugeon village. This transect is approximately 5.4 km long, of which 1.4 km follow the river. It sampled the bird population of the river, the marshes more or less wooded with willows, birches and a few spruces, and the neighboring meadows and pastures. The flour mill dam provides a 3660 square meter body of water that is not flushed out because it is attached to a dwelling house. This is the only non-huntable wetland area along the two transects. The Sainte-Colombe transect starts from the village, crosses the mesophilic and then wet meadows to reach almost the downstream end of the Bannans transect. It then runs along the river in its undisturbed part to the Chaffois mill. The return to the village is via an agricultural path that crosses mesophilic and humid meadows, a marsh and a small wood of poplar and spruce trees. This transect is 8.6 km long including 2 km along the river. A U-shaped pond carved out of a marsh provides an open water surface of approximately 3400 square meters. It was also prospected during the transect. ' Mat sup 2 ...
