The Oriental Pied Hornbill Anthracoceros albirostis is the smallest of the Bornean hornbills.  It is also the most common, most probably due to its ability to adapt to changing habitat.  I have seen it feeding on oil palm fruit and on one occasion took a young of a White-breasted Wood-swallow.  It is probably most at home in primary forest but also does well in swamp forest.

The Asian Black Hornbill Anthracoceros malayanus sticks to primary forest and its fig trees and because of the continued reduction of such forest, this bird is considered as near threatened.  I still rate it as more common than the hornbills with the exception of the Pied and Wrinkled.

Much have been said about the nesting habits of hornbills.  Additionally the White-crowned Hornbill Berenicornis comatus is also one of those hornbills which occasionally practices co-operative breeding where other birds will take their turn at feeding the imprisoned female.  I saw this particular male bird foraging at almost ground level.  On all previous occasions, I saw them at around the middle storey of the forest.  I continue to be impressed with the fantastic white crest.
