The Western Bluebird (Sialia mexicana bairdi) is a medium-sized (16-19 cm [6-7.5 in]), highly social bird that lives in open coniferous and deciduous woodlands. Males are bright blue with a rust-orange breast and upper back, while females are gray buff with a pale orange wash on the breast and touches of blue on the wings and tail. It is found across the western US, from southern British Columbia to Baja California. The Western Bluebird will experience a high degree of climate exposure and has a high adaptive capacity. Overall, it has a Climate Change Vulnerability Index ranking of Less Vulnerable under both Representative Concentration Pathway (RCP) 4.5 and RCP 8.5 Scenarios. The Western Bluebird’s climate change vulnerability is impacted by factors related to movement and life history, which influence its ability to shift in space and persist in place.
