Resumen:
Physiological traits are promising indicators of population health in the face of rapid changing environments. We obtained values of diverse physiological parameters for Two-banded Plovers (Charadrius falklandicus) in coastal sites in Patagonia, Argentina, with the objective of determining the timeline in which these parameters become affected by the stress of capture and handling and of obtaining reference values for future monitoring of these patagonian populations. We analyzed packed cell volume, white blood cell profile, heterophil /lymphocyte ratio, bacterial agglutination titer, and total protein, glucose, triglyceride, and cholesterol levels in apparently healthy birds. Glucose, total white blood cell count, lymphocytes and eosinophil levels showed changes with handling times > 60 minutes after capture. The remaining parameters did not manifest significant alterations in response to capture and handling of up to 232 minutes (average = 105.2 ± 56.7). Therefore, although researchers should attempt to obtain blood samples as soon as possible after capture, inclusion of physiological parameters in monitoring studies of species not easily sampled in a few minutes, as Two-banded Plovers and other shorebird species during migration, should not be discouraged. Data presented here constitute the first physiological report for the species and can be considered as reference values during the non-breeding season at Patagonian coastal sites.
