Analysis of serum parameters provides information about body condition, nutritional state, and health status of individuals/species, and has broad application in ecological research and veterinary diagnosis. This study establishes baseline values for serum chemistries of the Olrog´s Gull (Larus atlanticus). Glucose, urea, uric acid, total protein, globulin, albumin, cholesterol, triglycerides, calcium and phosphorus concentrations were determined, and the activity of the follow enzymes: alkaline phosphatase, creatine phosphokinase, aspartate aminotransferase, and alanine aminotransferase measured. Thirty non-breeding gulls (juvenile and sub-adult individuals) were captured and studied in Mar Chiquita Reserve (Buenos Aires, Argentina) during the wintering periods 2016 (n = 17) and 2017 (n = 13). In general terms, most values for the parameters reported were in line with those previously described for other seabirds. The year had a significant effect on several of the biochemical parameters evaluated, and the sex had a significant effect on the alkaline phosphatase and calcium. This study has defined the serum biochemical reference signatures for free-ranging Olrog´s gulls during the non-breeding period, and contributes to the knowledge of the overall health status of this threatened and endemic species.
