What is the average life-span of a wild adult red-tailed hawk once it reaches adulthood?

The average life span of a wild adult red-tailed hawk is generally around 10 to 15 years, depending on their environment and various ecological factors. Once they reach adulthood, they are more resilient to the challenges that juvenile hawks face, such as predation and the difficulties of finding food and shelter as they learn to hunt. Therefore, the correct answer regarding the average life span once they reach adulthood is closer to the upper range of that spectrum, which would be 10 years. This reflects the typical longevity seen in wild populations of red-tailed hawks. The incorrect choices suggest significantly shorter life spans, which do not accurately represent the life expectancy of these birds in their natural habitats.
