Abstract
Parks are biodiversity hotspots in urban landscape, and has considered as “shelter” of creatures lived in urban. This researchaims to understand the effect of theimportant factors on terrestrial breeding bird communities and its functional guilds in urban parks. Bird community surveys of 100 parks larger than 1 ha in Taipei basin were conducted three times during March to July in 2013 using total counting. I used generalized linear models andAkaike’s Information Criterion to analyze the seven important factors:park area, the degree of isolation of habitat, the degree of isolation of river, vegetation index, artifact coverage, canopy coverage and the presence of water bodies with the bird species richness, bird density, and bird diversity of terrestrial breeding birds and its feeding guilds and habitat guilds.
Park area were main factor affected the species richness and density, and larger parks tended to support more species but lower density. Presences of water bodies were found to enhance species richness and diversity, especially in omnivores and generalists guilds. In addition, degree of isolation of river showed negative relations with total species richness and had different responses within habitat guilds. Both artifact coverage and canopy coverage had negative effects on total bird richness. Degree of isolation of habitat and vegetation index did not have significant impacts on total species richness, density, and diversity, but only had positive effect on woodland bird richness and diversity. In conclusion, park area park size, presence of water bodies, and degree of isolation of river affected bird community structure, and different functional guilds had different response to seven important factors.
