Sapsuckers drill new holes each spring
In the photo at right, two new holes have been drilled to the right of three holes made the previous season by this bird.
Sapsuckers drill holes in the bark starting at pecan bud swell. These birds create the holes in order to feed on the abundant and sugary sap that is flowing up the tree trunk in early spring. You will find that sapsuckers prefer certain pecan cultivars over others. I have never seen a 'Stuart' pecan tree that isn't riddled with sapsucker holes.
Although truck damage can look awful, a well tended pecan tree can withstand sapsucker feeding without significant yield loss.
