The most easily recognized sap holes are found in birch trees during the breeding season. [citation needed] Because sapsuckers attack living trees, they are often considered a pest species. [6] Intensive feeding by sapsuckers is a cause of severe tree damage and mortality, with certain tree species more adversely affected by feeding than others.
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] Certain tree species are particularly susceptible to dying after being damaged by yellow-bellied sapsuckers.
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]

Originally, the female was considered to be a different species and named the black-breasted woodpecker by Cassin. Measurements: Length: 8.3-9.8 in (21-25 cm) [3] Weight: 1.6-1.9 oz (44-55 g) [3] Wingspan: 17 in (43 cm) Male with sap wells. They excavate a new nesting cavity each year, sometimes reusing the same tree.
Like other woodpeckers, insects form a large part of the diet, being caught on the wing in some species, but fruit is also eaten in large quantities and some species consume sap. They all nest in holes that they excavate in trees, and the red-crowned woodpecker and the Hoffmann's woodpecker are unusual in that they sometimes enter their holes ...
