What is the term for the male Wood Duck's appearance after the breeding season concludes in early summer?
Answer
Eclipse plumage
Following the intense courtship period, the male Wood Duck undergoes a dramatic transformation into what is known as eclipse plumage, typically starting in the early summer. During this phase, he sheds his intricate, kaleidoscopic breeding colors and becomes predominantly gray or grayish-brown, losing the bold white striping found on his face and neck. This change serves a critical survival function, offering camouflage during a period of vulnerability after breeding. Even in this subdued state, the drake remains identifiable by retaining his distinctive red eyes and bill coloration.
