The Clark's Grebe (Aechmophorus clarkii) is a large (55-75 cm [22-30 in]) waterbird that has a black cap and back, white neck and underside, and is distinguishable from the Western Grebe (Aechmophorus occidentalis) by its white face and bright yellow bill. It breeds in the western US, Mexico, and southwestern Canada. It inhabits marshes, lakes, and bays where it feeds on fish and aquatic invertebrates. The Clark’s Grebe 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 Clark’s Grebe’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.
