Bird surveys were conducted in July 2007 in four habitats,including even-green forests,shrubs,nursery and park,at lower mountain regions in West Tianmu Mountain.No significant difference in bird species richness was found between shrubs and evergreen forests,while bird density in evergreen forests was significantly higher than that in shrubs.Bird species richness and density in evergreen forests and shrubs were significantly higher than that in nursery and park.There was high similarity between bird communities in nursery and in park.Widely-distributed species was the main composition of the bird communities in nursery and park,while narrowly-distributed species was only recorded in even-green forests and shrubs.This suggests that habitat change caused by human activities has disadvantageous effect on bird community.
