What specific term is used to describe the neat, shallow holes drilled by the Yellow-bellied Sapsucker into living trees?
Answer
Wells
The feeding technique employed by the Yellow-bellied Sapsucker results in a very specific physical marking on the tree. Instead of drilling deep cavities aimed at extracting insects from the interior wood, the bird creates shallow holes that penetrate the bark and the outer sapwood layer. These deliberately created openings are precisely referred to as wells. These wells are not drilled randomly; they are methodically arranged, often appearing in orderly rows or distinct patches on the trunk or limbs of the host tree. The bird repeatedly visits these wells to consume the sugary liquid that wells up as the tree responds to the injury.
