The Pink Robin is a small tubby bird, and is easily over-looked, being quieter than other robins. Males are brownish-black above, with a black throat and head. There is a small white spot above the bill, which is a buff spot on the female. Males have a diagnostic pink wash on the breast which extends right down under the belly. Females are a warm olive-brown above, with cinnamon buff underparts with a pinkish tint. Females and young birds have diagnostic buff wing patches. This species has a plain dark tail, lacking the white edges of other Petroicarobins.
