Red-breasted Sapsucker

Birds are a type of woodpecker and will make uniform holes in rows on a tree, especially in the early spring.  They sip on the dripping sap from the holes.

Control:

To discourage sapsuckers from feeding on a favorite shade tree, wrap hardware cloth or burlap around the area being tapped or smear a sticky repellent material, such as bird tanglefoot, on the bark.
