摘要
Foraging behavior of 6 Anas spp. [A. strepera, A. americana, A. crecca, A. acuta, A. platyrhynchos and A. rubripes] was studied during autumn at Long Point Bay, southwestern Ontario [Canada]. Data were collected using Cody''s technique, but statistical analyses identified significant differences among species that could not be discerned from qualitative examination of foraging-behavior curves alone. A relationship between similarity in body size and dissimilarity of foraging behavior was observed.
