The Changeable Hawk-Eagle, also known as the Crested Hawk-Eagle, is a large bird of prey found in Asia. This eagle is known for its unique coloration, which can vary greatly depending on the bird’s age, sex, and geographic location.
Adult Changeable Hawk-Eagles typically measure around 60-70 cm (24-28 in) in length and have a wingspan of 140-170 cm (55-67 in). They are usually brown on the upperparts and white on the underparts, with distinctive black-and-white bars on the tail and wings. Their legs and feet are yellow and their eyes are dark brown.
Juvenile Changeable Hawk-Eagles have a very different appearance than adults. They are mostly brown with a pale head and underparts, and their tail is barred with white. The eyes of juveniles are also a distinctive bright blue-gray color.
The coloration of the Changeable Hawk-Eagle can also vary depending on geographic location. For example, birds from Southeast Asia tend to be darker and more heavily barred than those from India or the Himalayas.
The name “Changeable Hawk-Eagle” comes from the fact that this bird’s plumage can change significantly as it ages. Juvenile birds gradually develop adult plumage over a period of several years, with the dark brown feathers gradually being replaced by lighter feathers.
In addition to their unique coloration, Changeable Hawk-Eagles are known for their powerful talons and sharp beaks, which they use to catch and kill prey such as lizards, snakes, and small mammals.
Overall, the Changeable Hawk-Eagle is a fascinating bird with a distinctive appearance that can vary greatly depending on age, sex, and geographic location. Whether you’re an avid birdwatcher or simply appreciate the beauty of nature, the Changeable Hawk-Eagle is definitely worth keeping an eye out for.
