Abstract Aims Long‐term climate stability, contemporary and environmental heterogeneity have been linked to bird diversity patterns through their direct impacts on diversification rate, as well indirect effects plant species richness, which could also directly indirectly affect diversity. This study aimed quantitatively assess whether these potential drivers richness the rate in birds eastern Asia. Location Mainland China. Taxon Birds. Methods Using distribution data of 1127 across 320 prefecture cities China a phylogenetic tree species, we analysed all birds, passerine non‐passerine respectively. We investigated relationships with long‐term climate, elevation range using ordinary least squares regression model simultaneous autoregressive model. In addition, structural equation was used analyse rate. Results The results showed that were highest southwestern Additionally, for higher than birds. Regression analyses revealed variable most associated three groups. Notably, from indicated glacial–interglacial change can influence by affecting rates. Main Conclusions These findings emphasize importance considering when understanding geographic highlight crucial role mountain regions stable paleoclimate forming maintaining biodiversity.
