The abundance and distribution patterns of great argus pheasant (Argusianus argus) in Bukit Barisan Selatan National Park, Sumatra, Indonesia

Abstract

I studied the abundance, habitat, and movements of Great Argus pheasants (Argusianus argus) in Bukit Barisan Selatan National Park, Sumatra, Indonesia. Distance methods using line transect conducted on monthly basis during 1998-2000 suggested that Great Argus pheasant density was about 2-3 individuals/km2. However, there is a need for more technique refinement. I found that camera trapping offers an alternative method to study secretive and elusive pheasant such as Great Argus. My studies suggest that males of Great Argus pheasant selected forest with more open understory for their dancing grounds. I also found that undisturbed forest with large trees was used more than other forest types. Great Argus pheasant also has larger home ranges than previous studies and these were not correlated with food abundance.
