Great Black Hawks (Buteogallus anthracinus) are known to live up to 7 years in the wild, with the oldest recorded individual observed in Arizona. However, their lifespan in captivity can be significantly longer, with some individuals living for over a decade.
The Lifespan of Great Black Hawks in Captivity
The lifespan of Great Black Hawks in captivity can vary depending on several factors, including the quality of care, access to medical treatment, and the overall environment they are kept in. Here are some key points about their lifespan in captivity:
-
Average Lifespan: In captivity, Great Black Hawks have been known to live for 10-15 years, with some individuals reaching up to 20 years of age.
-
Factors Affecting Lifespan: Factors that can contribute to a longer lifespan in captivity include:
- Consistent access to high-quality food and water
- Proper veterinary care and treatment of any health issues
- Stress-free and enriched living environment
-
Protection from predators and harsh environmental conditions
-
Comparison to Wild Lifespan: The lifespan of Great Black Hawks in captivity is significantly longer than their counterparts in the wild, which typically live for 7 years or less. This is due to the controlled and safer environment provided in captivity.
-
Notable Examples: There have been several notable examples of Great Black Hawks living long lives in captivity:
- A Great Black Hawk at the Phoenix Zoo in Arizona lived for over 20 years.
- Another individual at the Audubon Zoo in New Orleans lived for 18 years.
- The famous Great Black Hawk that was found in Maine in 2018 and taken to a rehabilitation facility is still undergoing treatment, and its future lifespan remains uncertain.

Several factors can contribute to the extended lifespan of Great Black Hawks in captivity, including:
Nutrition and Veterinary Care
In captivity, Great Black Hawks have access to a consistent and balanced diet, as well as regular veterinary check-ups and treatment for any health issues. This ensures they receive the necessary nutrients and medical attention to maintain their overall well-being.
Stress-Free Environment
Captive environments are designed to minimize stress and provide a safe, enriched living space for the birds. This includes features like appropriate perches, hiding spots, and opportunities for natural behaviors, which can help reduce stress and improve their overall health.
Protection from Predators and Harsh Conditions
In the wild, Great Black Hawks face threats from predators, severe weather, and other environmental challenges. In captivity, they are protected from these threats, allowing them to live longer and healthier lives.
Specialized Care and Monitoring
Captive facilities employ trained professionals who closely monitor the health and behavior of the Great Black Hawks in their care. This allows for early detection and treatment of any issues, which can significantly improve their lifespan.
Conclusion
While Great Black Hawks in the wild typically live for around 7 years, their lifespan in captivity can be significantly longer, with some individuals reaching up to 20 years of age. This extended lifespan is due to the controlled and safer environment provided in captivity, which includes consistent access to high-quality nutrition, veterinary care, and protection from predators and harsh environmental conditions. As the case of the Maine Great Black Hawk demonstrates, the specific lifespan of a captive individual can vary depending on the unique circumstances and the success of rehabilitation efforts.
