Abstract: The Western Marsh-Harrier (Circus aeruginosus) is an Eurasian species rarely recorded in the Western Hemisphere. We document a female at the Laguna Cartagena National Wildlife Refuge in Puerto Rico from 14 January to 30 March 2004 and an immature at the same locality from 11 January to 11 February 2006. These records represent the second and third for the Western Hemisphere and the first for Puerto Rico.
