The Black Swift (Cypseloides niger) is a large (18 cm [7 in]) swift that often can only be identified in the hand. Though its range is large (from Alaska to northern South America along the western coast and in the Caribbean Isles), few nest localities have been identified. It nests in cliffs and caves near water and are most commonly found nesting behind waterfalls. The Black Swift will experience a high degree of climate exposure and has a moderately high adaptive capacity. Overall, it has a Climate Change Vulnerability Index ranking of Highly Vulnerable under both Representative Concentration Pathway (RCP) 4.5 and RCP 8.5 Scenarios. The Black Swift’s climate change vulnerability is impacted by factors related to distribution, movement, and abiotic niche, which influence its ability to shift in space and respond to climate change impacts. It also has documented or modeled responses to climate change that impact its vulnerability score.
