The area around and behind their eye is red and their ear coverts are dusky. Their rear crown is greenish blue, their nape green, and the rest of their upperparts and their underparts are yellowish green. Most of the body feathers have black edges that give a scalloped appearance.

Their wing's leading edge and primary coverts are red, the outermost primaries are green with blue towards the end, and the rest of their primaries and their secondaries are rich blue. Their iris is orange surrounded by bare white skin and their bill and legs are yellow.
