The tawny eagle (Aquila rapax) is a bird of prey found in Africa and parts of Asia, with a total population estimated to be between 100,000 and 499,999 individuals. This species is considered to be polymorphic, meaning that there is considerable individual variation in plumage, resulting in occasional disparities in plumages that can engender confusion in some.
The Tawny Eagle Population: Estimated Numbers
According to the International Union for Conservation of Nature (IUCN), the global population of the tawny eagle is estimated to be between 100,000 and 499,999 individuals. This species is classified as ‘Vulnerable’ due to a decline in population caused by various factors, including deforestation and urbanization.

Tawny eagles can measure from 58 to 75 cm (23 to 30 in) in total length, with a typical length being about 65 cm (26 in). Their wingspans can range from 157 to 190 cm (5 ft 2 in to 6 ft 3 in). The weight of fully grown tawny eagles can vary from 1.5 to 3.1 kg (3.3 to 6.8 lb), with the average weight being reported as 1.91 kg (4.2 lb) in males and 1.97 kg (4.3 lb) in females. The mean mass of the species is estimated to be 2.3 kg (5.1 lb).
Adults can vary in coloration from all dark grey-brown to an occasionally streaky (or more plain) foxy-rufous to buffish-yellow. Most adults are usually a general grey-brown or rufous-tawny color, with occasional pale spotting visible at close quarters on the nape and belly, coverts uniformly toned as the body.
Habitat and Feeding Habits of the Tawny Eagle
Tawny eagles are found in a variety of habitats, including savannas, grasslands, and open woodlands. They primarily feed on small animals and birds, such as hares, ground squirrels, and small birds. The decline in forest cover has led to a decrease in the availability of food for the eagles, as their primary diet consists of prey that also rely on forests for habitat.
Threats to the Tawny Eagle Population
The primary anthropogenic reason for the decline of the tawny eagle is the decrease in the number of large, tall trees, which the birds use to build their thick nests. This is due to deforestation and urbanization, which have led to a loss of nesting sites for the eagles.
Additionally, the tawny eagle is threatened by other human-related factors, such as poaching and habitat destruction. These threats have contributed to the species’ reclassification as ‘Vulnerable’ by the IUCN.
Conservation Efforts for the Tawny Eagle
To address the decline in tawny eagle populations, conservation efforts should focus on preserving and restoring forests and tall trees, providing adequate nesting sites for the eagles. Additionally, efforts should be made to protect the eagles from human disturbances and threats, such as poaching and habitat destruction.
By taking these steps, we can help ensure the survival of this unique bird of prey for future generations.
Conclusion
The tawny eagle is a fascinating and important species that plays a crucial role in the ecosystems it inhabits. However, its population is under threat due to various factors, including deforestation and urbanization. By understanding the current status of the tawny eagle population and implementing effective conservation measures, we can work to protect this remarkable bird of prey for generations to come.
