A 10–15-year-old Pistacia chinensis 'Keith Davey' shows perfect rings of holes with sap flow, dead cambium above/below wounds, and branch dieback. A nearby pistache is healthy.

The pattern is classic yellow-bellied sapsucker (a woodpecker) feeding. These birds drill orderly rows of holes to feed on sap and attracted insects. Common on pecans and ornamentals. The tree can usually tolerate this unless already weakened.
