SAVING THE HORNBILLS
Safeguarding the hornbill population by building artificial nests in order to enhance breeding
In Sumatra there are 9 species of Hornbills, five of which can be found in the Muaro Duo reserve
Many species of hornbills are threatened especially due to the loss of nesting sites.
Indeed, Hornbills nest in natural tree cavities and certain species, such as Buceros bicornis, Buceros rhinoceros and Rhyticeros undulatus need large trees which can provide cavities adapted to their size. However, most Sumatran forests are secondary forests which have suffered from selective cutting whereby the tall, emerging trees have been felled thus destroying the nesting sites of these mystical birds.
For 7 years, we have monitored a couple of Rhinoceros hornbill living in Muaro Duo. In all these years, this couple has never bred.
