城市绿色空间（UGS）往往支持不同的鸟类集群。目前的证据表明，大型UGS是圆形的，并包含丰富的树冠覆盖将支持更多的鸟类物种独立的UGS隔离。在这里，我们使用eBird公民科学数据库在18年期间（2002-2019）的鸟类发生信息，估计鸟类物种丰富度的年度和季节性模式，在调查良好的纽约市绿色空间。面积是最强的年度（n= 102 UGS）和季节性物种丰富度（n= 43 UGS），而形状和隔离缺乏显着的关系。增加50%的面积导致每年增加11.5%，季节性物种丰富度增加8.2%。没有证据表明这些关系包含上限。树冠覆盖度与物种丰富度呈弱相关。春季和秋季，北向迁徙物种的丰富度与面积有很强的相关性，特别是非雀形目物种。鸟类的物种丰富度与春季的树冠覆盖度密切相关，树冠覆盖度增加50%会导致物种丰富度增加23.3%。我们的研究结果强调了面积的广泛重要性，春季移民的树冠覆盖的价值，以及形状和隔离的有限相关性。努力增加面积和树冠覆盖将增加留鸟和候鸟物种的数量，这可能会增加城市环境中其他对面积敏感的森林分类群的数量。
Urban green spaces (UGS) often support diverse bird assemblages. Current evidence suggests large UGS that are circular in shape and contain abundant tree canopy cover will support more bird species independent of UGS isolation. Here, we use bird occurrence information from the eBird citizen-science database over an 18-year period (2002–2019) to estimate annual and seasonal patterns of avian species richness in well-surveyed New York City green spaces. Area was the strongest correlate of annual (n= 102 UGS) and seasonal species richness (n= 43 UGS), whereas shape and isolation lacked significant relationships. Increasing area by 50% resulted in an 11.5% increase in annual and an 8.2% increase in seasonal species richness. There was no evidence that these relationships contained an upper limit. Tree canopy cover was weakly correlated with annual species richness. The richness of nocturnally migrating species was strongly correlated with area in the spring and autumn, especially for non-passerine species. The species richness of nocturnally migrating passerines was strongly correlated with tree canopy cover in the spring, where a 50% increase in canopy cover resulted in a 23.3% increase in species richness. Our findings emphasize the broad importance of area, the value of tree canopy cover for spring migrants, and the limited relevance of shape and isolation. Efforts to enhance area and tree canopy cover will increase the number of resident and migratory bird species, which will likely increase the number of other area-sensitive forest taxa that occur in urban environments.
