| 要約: | Hombills (Family Bucerotidae) are another bird with large bills besides the American toucans. This Bornean family is famous with their peculiar nesting habits. They are distributed in tropical Africa and Asia. Most of Borneo Hornbills is categorized as near threatened species under The IUCN Red List. In this study, all Borneo hornbills from Sarawak Museum which consist of eight species had been examined. Data of five species which are White Crested Hornbill, (Berenicornis comatus), Bushy Crested Hornbill (Anorrhinus galeritus) ,
Wreathed Hornbill (Aceros undulates), Rhinoceros Hornbill (Buceros rhinoceros) and Helmeted Hornbill (Buceros vigil) were obtained from previous study. Eight parameters that include
tarsus, bill length, bill width, bill depth, head bill, wing length, total length and tail length had been measured. All the parameters were analyzed by cluster analyses, discriminant function analyses (DFA) and logistic regression. Overall, the discriminant function analyses shows wing length is a character that differentiate between species, cluster analyses of 122 individuals are clustered into eight groups. Results of
logistic regression, the result showed there was insignificant different between male and female. |
