Figure 2. Countries and regions of the former USSR where birds ringed in the Camargue were recaptured for 7 species (n = number of ring recoveries and m = number of marked individual birds): A) mallard (Anas platyrhynchos), n = 434, m = 13,176; B) green-winged teal (A. crecca), n = 3,903, m = 58,347; C) garganey (A. querquedula), n = 181, m = 2,436; D) tufted duck (Aythya fuligula), n = 313, m = 3,845; E) common coot (Fulica atra), n = 99, m = 7,866; F) purple heron (Ardea purpurea), n = 39, m = 5,017; G) common snipe (Gallinago gallinago), n = 54, m = 2,445. These maps provide an insight into the potential origins and dispersion areas of birdborne pathogens.
