| Coracina newtoni (Pollen, 1866) |
The Reunion Cuckoo-shrike, Coracina newtoni is an endangered forest bird from the island of Réunion in the Indian Ocean. This species in the cuckoo-shrike family is restricted to two small patches of forest in the north of the island.
The Reunion Cuckoo-shrike is a small arboreal bird. The plumage is dimorphic between the sexes. The male is grey coloured with a darker back and lighter underside; the face is darker and has the impression of a mask. The female is quite different, being dark brown above and striped underneath with a white eye-line. The call of the species is a clear whistled tui tui tui, from which is derived its local French name, the Tuit-tuit.
The species is restricted to the canopy of native forests, occurring today in subtropical mountain forests. It is thought to have once ranged across the whole of Réunion's lowland forests. The diet of this species is principally insects, though fruit are also taken.
The Reunion Cuckoo-shrike is an endangered species and is currently the focus of conservation efforts. Its range has declined significantly and is currently an area of just 16 km². The population of the species is currently stable but at the low number of around 240 birds, and is very vulnerable to localised disasters such as forest fires or habitat degradation. Introduced cats and rats prey on the species (particularly on young birds), and introduced herbivores such as deer degrade what little habitat remains. Pilot studies have shown that controlling rat and cat numbers around nesting sites leads to increased survival of chicks, and the test programme of trapping and poisoning is going to be expanded. The species' survival plan also includes recommendations to translocate some individuals to suitable habitat in other parts of the island.
