摘要

Chu Yang Sin Nature Reserve, Dak Lak Province, Vietnam, is within an area of high bird endemism and supports a number of globally threatened and restricted-range species. Data were collected on the bird communities of the Reserve and their habitat in 1995, to ascertain habitat associations of some of the endemic and threatened taxa. Birds were surveyed in circular plots around a recording point. Habitat associations were investigated using Discriminant Function Analysis, and populations estimated using DISTANCE. Seven restricted-range species and 38 restricted-range subspecies were recorded in the survey. The number of contacts with some of the endemic species was low, which limited the statistical investigation of the habitat requirements of these species. When analysis was possible, altitude was the most important of the factors measured determining species distributions, while measures of forest architecture seemed less important. The area appears to support important populations of several restricted-range taxa and, provided that protection and management of the protected area can be enhanced, it remains one of the most important areas for bird conservation in southern Vietnam. Some drawbacks of the techniques used in the survey are discussed.
