Identification
The Reunion Bulbul, as its name suggests, is endemic to the island of Réunion. Locals refer to it as Merle pays (Merl pei in Creole). It is not to be confused with the Eurasian Blackbird (Pycnonotus jocosus), which is also present on Réunion. Quite similar to other bulbuls in the Madagascar region and still more to the Mauritius Bulbul (Hypsipetes olivaceus), it is more olive-green and is the only one with white irises. There is no sexual dimorphism in this species. The female only has slightly smaller measurements than the male. They all have a common crown with black and shaggy feathers. The feathers on the head become grey ash until the back of the neck, the sides, the throat and chest. The lores remain well black like the crown feathers. The mantle is also grey ash but a bit lighter, with slightly darker streaks. The back, the rump and the stomach are dark olive-grey, some feathers on the lower belly are dirty white. The tail and wing feathers are dark grey-brown with slight black edges. The beak and feet are orange. Juveniles differ from adults in the intensity of the colours, which are more dull and pale. The primaries and secondaries are a rust colour.

Habitat
The Reunion Bulbul is a strictly forest bird. It remains, however, absent from forested areas beyond 1,800-2,000 m.
Behaviour character trait
The Reunion Bulbul moves in pairs or small groups of up to 10 individuals if the food concentration is high.
Dietfeeding habits
The Reunion Bulbul mainly feeds on endemic fruits and nectar from flowers that it takes directly from the trees. The fruits of the Change-écorce (Aphloia theiformis) seem to be the most abundantly consumed, in addition to the Bois de fer bâtard (Sideroxylon borbonicum) and other species of the island. It may also consume insects that it clumsily catches while flying.
Reproduction nesting
The nesting of the Reunion Bulbul is very poorly known due to the species' great discretion. The female lays 2-3 pinkish white eggs speckled with gray and dark red in a roughly cup-shaped nest in the middle of a fork during the Austral summer (July to December). The young are fed by the parents for two months, mainly with insects and larvae.

evaluated
The Reunion Bulbul was part of the hunting game until 1988. The capture using glue was also very common to be served as a dish or as a caged bird. Finally, it was another victim of deforestation. All these reasons led to a dramatic drop in its populations, to the point where the survival of the species was uncertain. It has been fully protected by ministerial decree since 1989, which has stabilized its population. Unfortunately, cases of poaching have not disappeared everywhere. In 2005, its population was estimated at 41,000 individuals.
