Acorns are an important winter food for some birds.
Some Kentucky birds are likely to consume acorns as a part of their diet, particularly in winter. The sweeter acorns of the white oaks (white oak, post oak, bur oak, chestnut oak, etc,) are probably more widely eaten than the bitter, tannin-rich acorns of the red oaks (red oak, pin oak, scarlet oak, black oak, willow oak, etc.)
*The wood duck's winter range includes a few counties in southwestern Kentucky.
