Resumen:
Blood parameters (hematology and biochemistry) are useful in assessing the physiological, nutritional, and overall health status of both captive and free-ranging wildlife. In this study, we established baseline values for blood parameters (hematology, plasma biochemistry, and trace elements) of free-ranging adult Magellanic Penguins (Spheniscus magellanicus) sampled at ten breeding colonies covering their full latitudinal distribution in Patagonia over two decades. Males had higher packed cell volume, heterophil and eosinophil relative counts, total solids, copper, and iron but lower magnesium than females. We also compared our results with those obtained in previous studies on both captive and free-ranging Magellanic Penguins and other Spheniscus species. Our study provides a baseline for ecological studies investigating the physiological responses of this species to natural and anthropogenic changes. Furthermore, our findings provide clinically relevant reference values for Magellanic Penguins under care at zoos, aquaria, and rehabilitation centers.
