| Résumé : | An invasion of Ruddy Shelducks Tadorna ferruginea into Fenno-Scandia in summer 1994 coincided with the occurrence of flocks in Britain. The patterns of the records and status in Europe are documented and discussed in an attempt to determine whether wild birds, escapes from captivity or individuals from feral populations were concerned in these movements. |
