Abstract:

In order to have an insight into the effect of habitat change on bird diversity, we investigated bird communities by transect sampling method in five habitats including natural marsh wetlands, river beach with open forest, and three artificial forests of young forest, 6-year-old forest and mature forest. A total of 66 bird species, belonging to 12 orders 31 families, were recorded, and among them 15 species were waterbirds accounting for 22.73% of total bird species. Insectivorous and omnivorous birds were dominant in terms of feeding guilds, accounting for 45.6% and 31.3%, respectively. The bird species and density were highest in the marsh wetlands, and the lowest in the young forest. Bird density significantly differed among the habitats and increased with forest age in three forest habitats. There was significant diffence in bird diversity among habitats. The year-round bird diversity in mature forests was next to that in open forest, and highest in the marsh wetlands. There was significant difference in bird density in diffent seasons. Bird diversity over the all habitats was ranked as the following:spring > summer > autumn > winter. Bird diversity was related to habitat complexity and vegetation types.

Key words: bird community, diversity, feeding guild, seasonal variation, Yangtze River beach
