Fowl-mouthed study finds that diet shaped duck, goose beaks

An analysis of the relationship between diet and beak shape among waterfowl not only shows that feeding is likely the major influence that fits the bill, but also suggests that early birds of the order were likely more duck-like than goose-like.
