What specific colors define the drake Wood Duck's bill, moving from base to tip?
Answer
Bright red at the base, transitioning to yellow, ending with a dark or black tip
The bill structure of the male Wood Duck, or drake, features a striking, multi-hued coloration that aids in its overall spectacular appearance. Specifically, the bill displays bright red coloration commencing at the base, which then transitions into a section of yellow color. This vibrant sequence culminates at the very end of the bill with a dark or black tip. This complex pattern contrasts sharply against the darker plumage of the drake's head. In comparison, the female's bill is significantly simpler, usually appearing dark gray or blackish, emphasizing the distinct identification feature offered by the male's bill structure.
