Spotted
The Changeable Hawk-Eagle is a widespread and polymorphic raptor found across tropical Asia, known for its highly variable plumage (light and dark morphs) and often prominent crest. It is a versatile predator of birds, mammals, and reptiles.
Where to spot
Forests, woodlands, plantations, and cultivated areas across a vast range from India and Sri Lanka east to Southeast Asia and Indonesia.
How to spot
Look for its medium to large size, broad wings, and a crest (which may be obvious or barely visible). Pay attention to its overall coloration (light or dark morph) and listen for its loud, far-carrying calls, a key identifier.
When to spot
Year-round, active during daylight. Frequently seen soaring or perched on exposed trees, often at forest edges.

Its common name refers to its considerable plumage variation, with individuals ranging from very pale to almost entirely dark brown, making field identification challenging at times.
