It's the sole representative of the Rhynochetidae family. The cagou is only living in the Caledonian rainforests and in some shrublands areas. We often hear , its cry in the "Parc de la Rivière Bleue" ("Blue River Park"), similar like a barking dog.

The cagou, the bird who does not fly is the emblem of New Caledonia. He is a threatened specie and therefore permanently protected.
