Most forest Galliformes are difficult to survey for several reasons: their secretive and cryptic behavior, their feeble call and usually occurred in dense forests. This study outlines the application of a camera trapping methodology for abundance estimation by using Siamese fireback Lophura diardi as an example. Camera-traps were installed at 46 survey points, 700 m apart, spread over 18 km2 of the study area, 14 days/location, between February and April 2010. Total of 622 trap-nights were accumulated (13.5(+-)1.5 day/trap) and 86 independent Siamese firebacks detections were obtained from 25 locations. The analysis program PRESENCE obtained an estimate of occupancy of 0.69 ((+-)0.10) while the probability of detection was 0.29 ((+-)0.05). The Royle-Nichols model gave the average abundance/sample unit of 1.48 ((+-)0.62) with the total abundance of 68.20 ((+-)28.41). This method is the systematic population survey technique for Siamese fireback and has the potential to be applied to other Galliformes.
