Abstract: Birds are highly dependent on food and habitat in urban landscape, and environmental factors are closely related to urban birds. However, the effect of land cover patterns on bird communities in urban areas remains unclear. From January to October, 2019, fixed line transect method was used to investigate the relationship between urban bird diversity and land cover in Lishui District, Nanjing, China. The results show that there were significant differences in the number and diversity index of bird species among seasons. The individual numbers of birds in spring and autumn were significantly larger than that in winter. The diversity indices in spring, summer and autumn were larger than that in winter, and the evenness index in spring was greater than that in winter. No significant difference was found in the number of individuals among seasons. The species richness was positively correlated with the proportion of farmland area, forest area and the landscape diversity index. The number of individuals was negatively correlated with the proportion of grassland area, and positively with the landscape diversity index. The diversity index was positively correlated with the proportion of farmland area. During spring, summer and winter, the individual numbers of omnivorous, carnivorous and granivorous birds were positively correlated with the proportion of grassland area, while the numbers of insectivorous and frugivorous birds were positively correlated with the proportion of forest area. The numbers of omnivorous, carnivorous and granivorous birds were positively correlated with landscape diversity index in spring and summer. The number of omnivorous birds was positively correlated with the proportion of construction land area in winter. The individual number in bird feeding guilds and the land cover pattern in autumn showed no significant correlations. In order to increase the number of bird individuals and species, it is suggested to increase the diversity of land cover pattern, and the proportion of woodland area, and to enrich the environmental heterogeneity of grassland in urban planning and management.
