The kori bustard (Ardeotis kori) is one of the largest extant flighted birds and is displayed in zoos primarily in North America and Europe. In captivity, kori bustard diets are primarily based on animal proteins, whereas in the wild these birds eat a wide variety of plants, insects, and small vertebrate prey. The purpose of this study was to compare circulating iron, total iron binding capacity, and percent transferrin saturation levels in apparently healthy wild and captive kori bustards. Adult captive kori bustards had slightly higher percent transferrin saturation levels than juvenile captive birds, although this finding was not statistically significant. This information can be referenced as a guide for the assessment of nutrition and health in captive birds.
