It superficially resembles a crow with its glossy black plumage and a curved beak.

Their bill is long and bicolored – yellow below, black above.

It has a loud, ringing call, which is predominantly heard in the early mornings.

This bird is critically endangered due to introduced rats.

Extensive surveys have only found it in the Parc de la Rivière Bleue area, on the slopes of the Kouakoué, in the Pourina and Ouiné valleys, at Rivière Blanche and on the slopes of Mont Pouédihi and Mt Panie.
