Courtship and copulatory behaviour of the New Zealand grey duck

Notornis, 16 (1), 23-32

M. Williams (1969)

Article Type: Paper

The displays and copulatory behaviour of the New Zealand grey duck are briefly described. Courtship is “social,” males gathering together in the presence of one or more females to perform the various sexual displays. Some displays (e.g., ritualized Preens) occur more frequently outside the social courtship groups, between members of a newly-established pair. Qualitative identity exists between displays shared by the grey duck and the mallard.
