Cool Facts
- In most species of woodpecker the sexes differ in appearance only subtly, usually with the male having red somewhere the female doesn't. Williamson's Sapsucker is unusual in having the male and female looking drastically different. The two sexes look so unalike that they originally were described as different species.
