IUCN - Near Threatened


Wrinkled hornbills are a relatively social species, found in flocks of up to thirty and in pairs while feeding. Like other hornbill species, wrinkled hornbills are monogamous. The monogamous pairs will return to the same nest site year after year. When nesting, the pair will build a nest in a hollowed out spot of a tree trunk. The female will then seal herself in using a mixture of mud, feathers, and food. The male feeds the female through a small slit during the incubation and brooding period. Females lay one to three eggs at a time. Incubation lasts approximately 30 days. After hatching, the female remains in the nest for up to four months brooding the chicks. After this period, the chicks will emerge with the female and forage with both parents.


Special Interests



The major threat to this species is habitat loss due to forest fires, logging, and land conversion.
