What distinctive pattern identifies a sap gallery drilled by a Yellow-bellied Sapsucker?
Answer
Neat, horizontal rows drilled through the bark
Identifying the work of the Sapsucker, known as a sap gallery, is crucial for locating the bird indirectly. Their feeding technique involves drilling small, precise holes arranged in straight horizontal rows. These rows are typically spaced about an inch apart and often encircle the trunk or branch. This method differs significantly from the more irregular, deeper holes created by other woodpeckers searching for insects.
