Geographic variations in eco-evolutionary factors governing urban birds: the case of university campuses in China

Urbanization alters natural habitats, restructures biotic communities, and serves as a filter for selecting species from regional species pools. However, empirical evidence of the specific traits that allow species to persist in urban areas yields mixed results. More importantly, it remains unclear which traits are widespread for species utilizing urban spaces (urban utilizers) and which are environment-dependent traits. 
Using 745 bird species from 287 university/institute campuses in 74 cities and their species pools across China, we tested whether species that occur in urban areas are correlated with regards to their biological (body mass, beak shape, flight capacity, and clutch size), ecological (diet diversity, niche width, and habitat breadth), behavioral (foraging innovation), and evolutionary (diversification rate) attributes.
We used Bayesian phylogenetic generalized linear mixed models to disentangle the relative roles of these predictors further and to determine the extent ..., , , # Data from: Geographic variations in eco-evolutionary factors governing urban birds: the case of university campuses in China

### **A. Description**

This dataset contains the data supporting the findings of the above article. In summary, this dataset includes 1,344 bird checklists from 287 university/institute campuses in 74 cities of China, resulting in a total of 745 species of birds (165 urban utilizers and 580 urban avoiders). The species-level information was also compiled, including their biological (body mass, beak shape, flight capacity, and clutch size), ecological (diet diversity, niche width, and habitat breadth), behavioral (foraging innovation) and evolutionary (diversification rate) attributes. In addition, the cities’ environmental and socio-economic status, and the detailed information on the references of avian checklists on university/institute campuses were provided.
