Abstract
Knobedd Hornbill (Rhyticeros cassidix) is an endemic species found only on Sulawesi Island. This bird is one of the most interesting species to observe because it is unique, half-shaped, and large compared to other bird species. Therefore, this study aims to provide accurate observation timing and feeding behavior information, which will be a means of interpreting birdwatching in Bantimurung Bulusaraung National Park. Observations were Observations were made of a pair of adults of Knobed Hornbill, which are seen nesting in karst cliffs. Observations of behavior were carried out for 3 days, in July 2023 with direct observation. This study shows routine nesting behavior that is very rare in other bird species. The results showed that parenting patterns were more dominated by male mothers, with the most time allocation being observed from around the nest. Knobed Hornbill is watched through a typical sound. The longest duration to do is standing or moving from one tree to the other right in front of the nest, with the longer duration reaching about 100 minutes. As for the male activity, it takes 3 to 19 minutes to feed the female.
