There are three subspecies of the booted eagle (Hieraaetus pennatus): A. p. harterti, A. p. minisculus, and A. p. pennatus. While the classification of birds of prey can be complex and subject to ongoing research and debate, these three subspecies are the recognized types of booted eagles.
The Three Subspecies of Booted Eagles
1. Hieraaetus pennatus harterti
- Also known as the Hartert’s booted eagle
- Breeds in southern Europe and North Africa
- Slightly larger than the other two subspecies
- Darker plumage, with a more distinct dark cap and darker underparts
2. Hieraaetus pennatus minisculus
- Also known as the small booted eagle
- Breeds in central Asia, from Turkey to western China
- Smallest of the three subspecies
- Paler plumage, with a less distinct dark cap and lighter underparts
3. Hieraaetus pennatus pennatus
- Also known as the common booted eagle
- Breeds in western and central Europe, and across Asia
- Intermediate in size between the other two subspecies
- Plumage coloration is between the other two subspecies
Distinguishing Features of Booted Eagles

Booted eagles are characterized by their fully feathered tarsi, or lower legs, which is a distinguishing feature from most other accipitrids (birds of prey). This gives them a distinctive “booted” appearance, hence the name.
In addition to the differences in size and plumage coloration among the three subspecies, booted eagles also share the following common characteristics:
- Small to medium-sized birds of prey, with a wingspan of around 1.5 to 1.8 meters
- Rounded, broad wings and a relatively short, slightly rounded tail
- Diverse diet, including birds, small mammals, reptiles, rodents, amphibians, and insects
- Migratory behavior, with Eurasian populations wintering in sub-Saharan Africa and the Indian subcontinent
Habitat and Distribution of Booted Eagles
Booted eagles have a wide distribution, breeding in southern Europe, North Africa, and across Asia, with a small, disjunct breeding population in southwestern Africa. They prefer a variety of habitats, including:
- Forested areas
- Mountainous regions
- Open woodlands
- Scrublands
- Grasslands
The three subspecies have slightly different breeding ranges, with Hartert’s booted eagle (H. p. harterti) found in southern Europe and North Africa, the small booted eagle (H. p. minisculus) in central Asia, and the common booted eagle (H. p. pennatus) in western and central Europe, as well as across Asia.
Conservation Status of Booted Eagles
The booted eagle is classified as Least Concern on the IUCN Red List of Threatened Species. However, some local populations may face threats such as habitat loss, persecution, and the use of pesticides. Conservation efforts, such as monitoring populations and protecting key habitats, are essential to ensure the long-term survival of these magnificent birds of prey.
In conclusion, there are three recognized subspecies of the booted eagle: Hieraaetus pennatus harterti, Hieraaetus pennatus minisculus, and Hieraaetus pennatus pennatus. These three subspecies share common characteristics, such as their fully feathered tarsi and diverse diet, but differ in their size, plumage coloration, and breeding ranges. Understanding the diversity and distribution of booted eagles is crucial for their effective conservation and management.
