The objective of the study is to compare the bird communities between natural forests and Taiwania (Taiwania cryptomerioides) plantations. I surveyed the bird communities in the experimental forests of Liu-Kuei Station, Taiwan Forestry Research Institute in Kaohsiung County, Taiwan during the breeding season from late March to early July in 2001 and 2002. A total of 34 bird species were recorded during the 2-year study period. Of these, thirty-one species were recorded in natural forests and 25 species in Taiwania plantations. Four indices, including diversity, evenness, species richness and total densities, could not clearly explain the differences between two forest types. Of the 11 assemblage guilds, carnivores and canopy woodpeckers only occurred in natural forests. The limited availability of nest holes limits the densities of species required holes to nest. Due to complex forest structures and stable and plentiful food resource, canopy foliage omnivores have stable densities in natural forests. But the very dense understory vegetation limits the number of suitable nesting or foraging sites require by ground insectivores. Because of less vegetation food resource, canopy foliage insectivores are the main component of the bird communities in Taiwania plantations. In addition, the foliage structure of the conifers is adequate for canopy hover insectivores to forage. The result of detrended correspondence analysis revealed that the differences of the bird communities between natural forests and Taiwania plantations mainly due to the complexity of the forest structures, nevertheless, the altitude and spatial variation would produce some impacts.
