The eye is cream and has pale lines above and below it. The area between the lines is grey. The chin and throat are off-white with coarse dark streaking. They have a black shoulder patch with overlying white markings. The area between the bill and the eye is blacker in males and greyer in females. The females also have less contrasting patterns.
