Hornbills (Family Bucerotidae) are distinguished omnivorous creatures, found in Asia and Africa and due to their large size and similarly large bill. In this study, only five out of eight species of Bornean hornbills are available, which are white crested (white crowned) hornbill (Berenicornis comatus), bushy crested hornbill (Anorrhinus galeritus), wreathed hornbill (Rhyticeros undulatus), rhinoceros hornbill (Buceros rhinoceros) and helmeted hombill (Rhinoplax vigil). Nine morphological features namely tail, tarsus, bill and wings are measured from approximately 83 specimens of 5 hombill species of Borneo available in the Sarawak Museum collections. The specimens were analyzed using the morphometric cluster analysis and they were successfully clustered into 5 species. Specimens of the Bushy-Crested hornbills and Wreathed hornbills were analysed in the same method and the results showed that there are variations between specimens of the same species from different localities. Logistic regression analysis was done for the Bushy Crested hombills and it showed that the diagnostic character for gender differentiation in this species is the total length. The result showed that males of Bushy Crested horn bills tend to be bigger in size than females.
