How do bird peck marks typically appear on walnut logs?

• A. Linear gouges along the grain
• B. Often in circles around the tree, penetrating the bark and cambium.
• C. Small random specks across the surface
• D. Deep holes from insect boring

Answer: (B)

Bird peck marks on walnut logs show up as a ring around the trunk because woodpeckers search the bark–cambium zone by moving around the circumference. They peck through the bark into the cambium to access sap and insects, leaving a circular pattern that encircles the tree rather than a single straight gouge or scattered specks. This circular ring is distinct from other damage types, which tend to be linear, random, or isolated holes.
