The presence of Larus dominicanus is reported for the first time in Sarigua National Park, Panama (8°1'60''N, 80°29'60''W), a semi-arid ecosystem characterized by high salinity and sparse vegetation. The record occurred incidentally in the La Albina sector during biweekly bird monitoring. Identification was confirmed through photographic analysis, noting white plumage with grey dorsals, black wings with white tips, a yellow beak with a red mark, and yellow legs. This finding suggests the species’ potential adaptation to arid environments, influenced by climate changes or resource availability, and underscores the need for continued monitoring to assess its impact on local ecological dynamics.
