The Réunion cuckooshrike (Coracina newtoni) is a passerine bird in the cuckooshrike family. It is endemic to the island of Réunion, where it is restricted to two areas of mountain forest in the north of the island. Males are dark grey above and pale grey beneath, while females have dark brown upper parts and a streaked breast. The population has been declining and the range contracting, being currently about 16 square kilometres (6.2 sq mi), and the International Union for Conservation of Nature has rated the species as "critically endangered", with the possibility that the bird could be wiped out by a tropical storm. Conservation efforts are being made by attempting to control the cats and rats which prey on the chicks, and this seems to have resulted in the population stabilising.
