The Violet-green Swallow (Tachycineta thalassina lepida) is a small, brightly colored bird (12 cm [5 in] long; 14 g [0.5 oz]). Males have purple and green irridescent upperparts and bright white faces, underparts, and side-rump patches. Females are less bright and have brownish heads. It forages for insects while flying and breeds in open woodlands with standing dead trees with cavities for nesting. It breeds throughout the western US and winters in Mexico. The Violet-green Swallow 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 Violet-green Swallow’s climate change vulnerability is impacted by factors related to movement, life history, and abiotic niche, which influence its ability to shift in space, persist in place, and respond to climate change impacts.
