Whitehead's Broadbill Calyptomena whiteheadi, the largest of the three green broadbills of Borneo, is an uncommon montane endemic of the pristine forests from Mount Kinabalu, Sabah, along spinal range of Borneo to Gunung Timbang, Sarawak/Kalimantan Timur. However, it can be common in localities during times when fruits are abundant.
I once photographed this species in Rafflesia Centre at the end of May, 2009, at that time there was no fruiting trees at the Centre, so they just moved-on without staying long for me to get decent photographs. See this post.
However, this visit of mine at the end of August coincided with fruiting of some trees at Rafflesia Centre and two of them came to feed which allowed me an opportunity to get some photographs. It was a pity that the position that I have to shoot from was facing the bright sky.
