Variation in relative brain size was examined in 55 species of waterfowl (Anseriformes). Using both conventional statistics and phylogenetically based comparative methods, the extent of variation in relative brain size and possible relationships with mode of foraging and diet were examined. The results indicate that although brain size does vary considerably between closely related species of waterfowl, it is not reliably related to either foraging mode or diet. There are a number of possible… CONTINUE READING
