The sexes have the same plumage. Adults of the nominate subspecies E. a. albiceps have a mostly dull olive to olive-gray head with a partially hidden white or creamy white stripe in the middle of the crest. They have whitish lores and eyering. Their upperparts are dull olive to olive-gray. Their wings are dusky with white or whitish tips on the coverts that show as two wing bars.
