Paper Title
Camera Trapping Hornbills in the Canopy in Borneo

Habitat modification is altering the landscape and affecting the potential breeding sites of the large iconic species of hornbills in the tropical rainforests of Asia. Of concern is the loss of old growth trees that provide large cavities, a necessary structure for these birds to breed. In this study five nest boxes were erected 18 m above the ground 12 months prior to installing camera traps and data loggers at them. During 505 trap days, between October 2014 and February 2016, a total of 54009 images were taken of which 6861 were of wildlife. In total 18 species were identified including five of eight species of hornbill that occur along the Kinabatangan River, Sabah, Borneo; hornbills made repeat visits to the nest boxes but none of them breed in them. In the same area three species (Oriental Pied Hornbill, Rhinoceros Hornbill and Helmeted Hornbill) were observed breeding during the study period in natural cavities. The interest in the nest boxes but lack of breeding suggests that tree cavities are a limiting resource but the design of the boxes may need to be adjusted to encourage breeding.
