One group of birds that inhabit Kutai and has significance for the local community which hornbill . Based on the results of an inventory of bird Kutai in 2012 , of which there are eight types of hornbills in Borneo , five types of which live in the national park . The type of gold that is looming Aceros undulatus , towering crested black Aceros corrugatus , hornbill Anthracoceros albirostris belly – white , black hornbill Anthracoceros malayanus , and hornbills klihingan Annorhinus galeritus .
However , like other types of animals in the region , where the large -beaked bird feared disturbed by the presence of Axis Way Bontang – Sangatta . Highway that divides the Kutai National Park is directly put pressure on the ecosystem by providing opportunities for the emergence encroachers along the way .
This is evident from our observations , Borneo Team Undercover Student Family Naturalist Ganesh Institute of Technology Bandung ( ITB ) in late January – early February 2014 ago . In observation for 6 days at two locations in the Kutai region is Sangkima and Prevab only a few types of hornbills were seen . In Sangkima forest , only two types of hornbills we observed that black hornbill hornbill and – white belly . While in Prevab , there are three types of hornbills were identified and there are other types that pass but we could not identify .
Our identification of the type that can include gold towering , towering crested hornbill – black and white belly . In addition , we also find that the four types of hornbills outside the location and time of observation . Hornbill type that we have encountered in Prevab more because in this area there is a fig tree Ficus sp being fruitful . Figs are a favorite feeding various types of birds including hornbills .
In general, the towering gold is the type most often we have encountered as many as 11 times encounter in Prevab and 11 times beyond the observation time . While in Sangkima only black hornbill hornbill and white belly visible because the condition of the habitat in this area is only appropriate for both these types . Forests in the area , touched Sangkima including Shaft Road Bontang – Sangatta so dominated the logged areas with an open canopy .
Several other types such as hornbill hornbill ivory require dense forest called the meeting so that the condition of the habitat in Sangkima not suitable for that type. Other types such as Borneo hornbill Buceros rhinoceros rhinoceros hornbill , hornbill ivory Buceros vigil , crested hornbills Aceros comatus , and hornbills klihingan Anorrhinus galeritus not observed at all . Possibly, this was due to the eastern region of Kutai already fragmented .
According to Mr. Bastar , a native mammal and a former Ranger who memorized true intricacies Kutai since the 1970s , first hornbill easily found in this region . At that time , at least five types of hornbills , including the rhinoceros hornbill ivory and hornbills are always up and down the forest . ” However , since the rampant illegal logging , and the rhinoceros hornbill ivory difficult hornbills found in Kutai , ” he said .
In tracing the existence of hornbills in Kutai we also had time to visit the Tanjung Bara , settlements in the mining area of PT Kaltim Prima Coal located at the northern boundary of Kutai . Settlers in the area said that the hornbills often come ” visit ” and not adjacent to the human fear .
Sure enough , upon arrival in the area , we were met with a belly – white hornbill . Birds which have predominantly black fur with a white beak and belly being perched on one of the trees and only about 10 m from the location of our stand . According to the people at Tanjung Bara , there are many other types of hornbills often stop by , unfortunately they do not know its type .

The possibility of the hornbill hornbill – like because the PT Kaltim Prima Coal has a very tight guard so untouched hunters and illegal loggers . The existence of hornbills in Tanjung Bara gives a glimmer of hope . We hope that other types of hornbills unsuccessful we observe still live peacefully in the core zone and the Kutai wilderness zone untouched . *
