What distinct feature characterizes the female Wood Duck's facial markings?

Answer

A distinct white teardrop patch around the eye

In contrast to the male's vibrant and complex coloration, the female Wood Duck displays much duller features, primarily a mottled grayish-brown body designed for camouflage while she is incubating eggs within a dark nest cavity. Her facial identification is marked by a specific feature: a distinct white patch shaped like a teardrop located around the eye area. This subdued coloration strategy ensures critical camouflage against potential predators during the vulnerable nesting period, highlighting the different selective pressures faced by males (visual signaling) and females (cryptic protection).
