Absence of blood parasites in Griffon vultures from Spain

Hematozoan parasites were not found on blood smears fron any of 82 Griffon vultures (Gyps fulvus) examined from Spain. These vultures represented samples of diverse temporal and spatial origin, and there was a great disparity in host ages (nestlings to > 5-yr-old adults) and physiological condition (growing, food-stressed, injured, and healthy birds).
