What is the primary geographic distinction for the Red-breasted Sapsucker (*S. ruber*) range?
Answer
It occupies the Pacific coast.
The geographic distribution of the three closely related sapsucker species shows clear regional separation, although interbreeding occurs at boundaries. The Red-breasted Sapsucker (*S. ruber*) is geographically associated with the Pacific coast region. In contrast, the Yellow-bellied Sapsucker (*S. varius*) is predominantly an eastern species, and the Red-naped Sapsucker (*S. nuchalis*) is typically found in the interior West, highlighting how differing environmental pressures across North America have influenced the divergence and maintenance of their distinct plumages and ranges.
