BNA: Soft "peeping" calls, apparently given by captive ducklings. BNA account does not mention any calls given by immature birds and I am not sure if this is the "bibibi" or the "pipipi" call described on page 604 of Cramp et al. (1977. The birds of Europe, the Middle East and North Africa. Birds of the Western Palearctic. Vol. 1. Oxford University Press, Oxford). CAM - 18 March 2005]. Number of individuals=NU2+;.
