One call, but two birds present. BNA: This appears to represent a single "zeee-ZEEE" call by a male goldeneye overlapped by a call by a goose (or Cygnus buccinator?) This particular call is described and pictured (in Figure II) on page 663 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), but not well described in BNA. (CAM - 18 March 2005).
