The striking Regent Honeyeater has a black head, neck and upper breast, a lemon yellow back and breast scaled black, with the underparts grading into a white rump, black wings with conspicuous yellow patches, and a black tail edged yellow. In males, the dark eye is surrounded by yellowish warty bare skin. Females are smaller, with a bare yellowish patch under the eye only, and have less black on the throat. Young birds resemble females, but are browner and have a paler bill. This species is gregarious, moving in flocks. It bobs its head when calling.
