The changeable hawk-eagle, aka crested hawk-eagle, marsh hawk-eagle, booted eagle, or Indian crested hawk-eagle, is a large bird of prey that hails from the Indian subcontinent and southeast Asia. They prefer Savannah woodlands, timbered watercourses, cultivations with trees, tea plantations, forest villages, and can even be found near suburban settlements. Even though they suffer at the hands of habitat destruction and collection for the pet trade, these birds are still listed as Least Concern by the IUCN. However, their populations are decreasing.
