Bitternut Hickory Buds

1-10-14 bitternut  hickory 102Habitat, silhouette, bark and buds can all be helpful when identifying a tree in winter. Occasionally a species has one characteristic that is so distinctive, it serves as a diagnostic feature. The sulfur-yellow coloring of Bitternut Hickory (Carya cordiformis) buds is such a characteristic. Both lateral and terminal buds have a powdery coating which gives them a bright yellow appearance. Look for Bitternut Hickory on moist lowlands (hence, its other common name, Swamp Hickory) and rich uplands. Although humans find the nut of this hickory inedible, the smoke produced by burning its wood produces the best “hickory-smoked” hams and bacon.

Black Walnut

Even though a late spring frost may have reduced this year’s crop of Black Walnuts (Juglans nigra), and even though the few that made it haven’t started falling on the ground yet, squirrels have already located and started consuming this nut’s fatty meat.  Inside the green husk is the actual nut, and if you look closely at the edges of the chewed hole as well as the inner surface of the nut, you will see tiny incisor marks, most likely left by red squirrels.  This particular rodent typically chews a hole on both sides of the nut, so that it can gain access to both halves of the meat.
