Adults have a yellow to greenish yellow bill and a small yellow to orange-yellow frontal shield, though these colors may further vary.

Immature birds have a dusky olive bill, greenish gray legs and feet, gray-brown upperparts, and paler underparts than adults. Juveniles are dark drab gray with dusky mottling on a white head and neck.
