Woodpecker Pecking Tree - Illustration for Bird Behavior Education #206032 (License: Personal Use)

This black-and-white line drawing illustrates a woodpecker clinging vertically to a textured tree trunk, its beak inserted into a freshly drilled round cavity. Fine cross-hatching renders feather patterns and bark grain, while a second bird appears mid-flight in the upper right, suggesting ecological interaction or species comparison.

Used in ornithology textbooks, nature education websites, and conservation outreach materials to demonstrate woodpecker foraging behavior, cavity nesting, and forest ecosystem roles; matches user intent for academic or illustrative reference.
