Comparative Behavior and Relationships of the Eiders
Pair-forming and copulatory displays of the four species of eiders are described and illustrated, based on observations of captive and wild specimens. Behavioral differences indicate that two genera (Polysticta and Somateria) of eiders should be recognized, and that Lamponetta should be considered a...
