How do they reproduce?
All species of hornbills including the bar-pouched wreathed hornbill are monogamous and mate for life. The breeding season varies according to their geographical distribution.
In India, the breeding season begins in April and lasts until June, in Thailand and Myanmar it starts in January and ends in March, whereas in Indonesia the season is from March to September.
They are not territorial and live in flocks even during this whole process.
They prefer living at lower altitudes during the breeding season as compared to their usual altitudinal preferences. About six or seven days before mating, each pair will seek out a tree cavity to lay their eggs in.
After which, a male seals his female partner inside the cavity by blocking the entrance fully with twigs, fruit pulp, soil, or mud, except a small portion so that he can provide food for and meet the diet requirements for her, and the young chicks as well.
In the course of incubation, as the female stays inside the cavity for at least four months she completely molts old feathers and regrows new feathers.
A wreathed hornbill female lays up to two or three pale white eggs and leaves the cavity only when the chicks are ready to fledge.
What is their conservation status?
The IUCN Red List of Threatened Species has classified the wreathed hornbill (Rhyticeros undulatus) as species Vulnerable to potential extinction.
