What striking feature contrasts the subdued coloration of the female Wood Duck?
Answer
A striking white patch surrounding each eye.
While the male *Aix sponsa* is famed for its exotic, iridescent display of greens, blues, and purples, the female possesses a coloration that is significantly more understated, often described as smoky gray. However, even in her muted appearance, there is a distinct, identifying mark: a striking white patch encircling each eye. This specific marking is key to distinguishing the female Wood Duck, even though her overall drab coloration might occasionally lead to confusion with females of closely related species, such as the female Mandarin Duck, which shares some general drab characteristics. This patch serves as a crucial identification marker across various lighting conditions.
