Taxonomy and systematics

The Réunion bulbul was originally described in the genus Turdus. Formerly, some authorities also considered the Mauritius bulbul to be a subspecies of the Réunion bulbul.[2] Alternate names for the Réunion bulbul include the Bourbon thrush, olivaceous bulbul, Réunion black bulbul and Réunion merle.

Description

The appearance of the Réunion bulbul is similar to that of the Mauritius bulbul but is slightly smaller with a length of 22 cm. It is ashy gray with a blackish crest and the iris is conspicuously white. The bill and feet have an orange hue.[3]

Behaviour and ecology

Breeding

The female lays two eggs in a cup-shaped nest during the southern summer.[3]

Food and feeding

The Réunion bulbul is primarily frugivorous. In February and March, it moves from areas of higher elevations, where it inhabits humid secondary forests, to lower valleys to feed on ripe guavas. Nectar, insects and small lizards enrich its range of food.[3]

Threats

Although assessed as a species Near Threatened by the IUCN, the Réunion bulbul is no longer a common bird, mainly due to poaching and competition from the introduced red-whiskered bulbul. In the earlier days of the settlement of Réunion it was hunted for food on a large scale, and was considered as tasty as the ortolan bunting (Emberiza hortulana). As late as the 1970s it was hunted excessively. It is also kept as pet.
