Methods

Breeding birds were monitored in spring during a longitudinal long-term scientific study that recorded point counts of any species heard or seen. Two sessions were run (20 min in April and 20 min between mid-May and mid-June), and the highest abundance for each species between the two sessions was retained. Point counts were regularly spaced along the riverbank (15 km depending on the river) to limit the risk of double counting birds moving across a large area, and were strictly identical for each session (Table S1). The final sample consisted of 319 point counts distributed as follows among the three rivers: nAllier = 90, nLoire = 198, nDoubs = 31. The Loire, Allier and Doubs were monitored, respectively, in 19892011, 19912006 and 19822013. During these periods, the Loire's birds were monitored four times, the Allier's birds three times, and the Doubs's birds 14 times, leading to a dataset of 1,286 bird census counts. In total, 174 species were recorded (present at least twice), of which 115 were terrestrial, and 59 were generally considered as aquatic. Only terrestrial species were considered in the analyses. This was because SSI indices are calculated from the French Breeding Bird Survey (FBBS), which is not appropriate for monitoring local, restricted wetland habitats (species are listed in Table S2). Variability associated with observers was limited, as only 12, experienced ornithologists conducted all censuses, and a given point count was monitored by the same observer, who adopted the same protocol each year.
