features

Dickschnabelbülbüle reach a body length of 24 to 25 centimeters and an average weight of 83.2 grams for the males and 74.4 grams for the females. There is no sexual dimorphism between the sexes in terms of plumage color . The birds are predominantly olive gray in color. The crown consists of a short black hood , which is sometimes erect.

distribution and habitat

The range of the Dickschnabelbülbüls includes all islands of the Seychelles and almost all habitats there. However, it is preferred in areas with coconut palms ( Cocos nucifera ), whereas it is less common in cities. It was also found on the highest point on the islands, the 905 meter high Morne Seychellois .

Way of life

The birds feed on various fruits, the eggs of other smaller bird species as well as arthropods , which are primarily sought in the treetops. They usually live in pairs, but groups of up to 15 individuals have also been observed feeding in fruit trees. The main breeding season falls from September to January. The almost circular nest with an outer diameter of 13 centimeters is made from dry grass, withered leaves, palm fibers, small twigs, fragments of bark and moss within six to ten days and placed at a height of up to 15 meters above the ground and usually with two Eggs loaded. The breeding business lasting 15 days is mainly done by the female. During the 21-day nestling period, the young are provided with food by both parents, but normally only one young bird survives.

Danger

Stamp

The Dickschnabelbülbül is widespread and not rare in almost all biotopes of the Seychelles. It is therefore classified by the World Conservation Organization IUCN as LC IUCN 3 1st svg“ least concern = not endangered”.
