A medium-sized dark gray bird with a black cap and a carrot-colored bill, endemic to the island of Mauritius. Found in remnant humid forest as well as secondary forest and some forest dominated by exotic trees; now mostly confined to middle and high elevations. Often in small, noisy groups. Somewhat similar to male Mauritius Cuckooshrike, but easily separated by the orange bill and many other details. The song is an unmusical but varied series of rattling, metallic, and scraping notes, often given from a high perch. The calls include a “chek” note and a long mew.
