Of Note
Squirrels are particularly fond of pignut oak nuts, and the nuts typically comprise 10-25 percent of the squirrels’ diet.

Pignut seed, averaging 200 seeds per pound, is lighter than the seed of other hickory species.

The kernel of hickory seeds is exceptionally high in crude fat, up to 70 to 80 percent in some species.
