What energy-rich nut is considered the most notable single food item in the Wood Duck diet foundation?

Answer

Acorn

The foundation of the Wood Duck's diet is built upon seeds, nuts, and tubers sourced from wetland and riparian plants. Among these, the acorn, a high-energy nut produced by oak trees, stands out as perhaps the single most notable food item consumed in large volumes when it becomes available in the autumn. This consumption pattern is so pronounced that in areas where mature oak stands border swamps, Wood Ducks become major consumers, which can lead to competition with terrestrial wildlife species such as deer and wild turkey that share access to the same dropped resource.
