Holes left by a sapsucker. As their name implies, sapsuckers feed primarily on the sap of trees, moving among different tree and shrub species on a seasonal basis. Insects, especially those attracted to the sweet sap exuding from sap holes, are often captured and fed to the young during the breeding season.
The birds can cause serious damage to trees, and intensive feeding has been documented as a source of tree mortality. [26] Sapsucker feeding can kill a tree by girdling, [27] which occurs when a ring of bark around the trunk is severely injured. [26] Ring shake—spaces between rings of growth in trees—can be a result of sapsucker injury. [28]
A sapsucker's tongue is adapted with stiff hairs for collecting sap. Red-breasted sapsuckers visit the same tree multiple times, drilling holes in neat horizontal rows. A bird will leave and come back later, when the sap has started flowing from the holes. Repeated visits over an extended period of time can actually kill the tree. [9]
