Abstract
The immune response in vertebrates is primarily mediated by leukocytes. Types of leukocytes in birds are basophils, heterophils, eosinophils, lymphocytes and monocytes. The leukocyte profile obtained from blood smear analyses is reported for a long distance migrant, the Red Knot (Calidris canutus rufa) during its wintering at Rio Grande, Tierra del Fuego, and its stopover site at San Antonio Bay, Río Negro, Argentina. Heterophils and lymphocytes were the most abundant leukocytes in both sites, while the other leukocytes showed lower proportions.
