The Changeable Hawk-Eagle is a forest raptor with pale and dark color morphs. The distribution and resident records cited here refer only to the documented localities.
Adult pale morphs are brown above and white below, with dark breast and belly streaks and a short crest. Dark morphs are blackish, with grey underwings.
At the Kamojang Eagle Conservation Center in West Java, Indonesia, researchers recorded the daily activity of a Changeable Hawk-Eagle during rehabilitation. They observed the bird in its enclosure every three days each week for five weeks, recording categories such as resting, movement, and feeding. The observations describe activity during the recovery period at the conservation centre.
Resting made up 74 percent of recorded activity and was the largest category. The 'other' category accounted for 4 percent and included tail movements, pecking the perch, and watching prey. The observation record shows that the rehabilitating eagle spent most of its observed activity resting, with smaller amounts of movement and other behaviours.
An extinction-risk assessment has not been added yet.
During five weeks of rehabilitation observations at Kamojang, resting made up 74% of recorded activity and the 'other' category made up 4%.
