The '''changeable hawk-eagle''' ''('''Nisaetus cirrhatus''')'' or '''crested hawk-eagle''' is a large [[bird of prey]] species of the [[family (biology)|family]] [[Accipitridae]]. More informal or antiquated English common names include the '''marsh hawk-eagle''' or '''Indian crested hawk-eagle'''.<ref name="Ferguson-Lees">Ferguson-Lees, J., & Christie, D. A. (2001). ''Raptors of the world''. Houghton Mifflin Harcourt.</ref> It is a member of the subfamily [[Aquilinae]], with signature feathers, absent in tropical raptors from outside this subfamily, covering the tarsus.<ref>Sheehy, R. R. (1995). ''A phylogenetic analysis of the Accipitridae (class Aves)''. University of Arizona.</ref> It was formerly placed in the genus ''[[Spizaetus]]'', but studies pointed to the group being [[paraphyletic]] resulting in the [[Old World]] members being placed in ''[[Nisaetus]]'' and separated from the [[New World]] species. It is a typical "hawk-eagle" in that it is an agile forest-dwelling predator and like many such eagles readily varies its prey selection between [[bird]]s, [[mammal]]s or [[reptile]]s as well as other [[vertebrate]]s.<ref name="Naoroji">Naoroji, R., & Schmitt, N. J. (2007). ''Birds of prey of the Indian subcontinent''. Om Books International.</ref> Among the members of its genus, the changeable hawk-eagle stands out as the most widely distributed, adaptable and abundant species.<ref name="iucn" /><ref name= Ferguson-Lees/> Individuals show a wide range of variation in plumage from pale to dark, varying with moult and age giving rise to the name "changeable".<ref>{{Cite web |title=Changeable Hawk-Eagle - eBird |url=https://ebird.org/species/y00839 |website=ebird.org}}</ref><ref>{{Cite web |title=Crested Hawk-eagles or Changeable Hawk-eagles &#124; Beauty of Birds |url=https://www.beautyofbirds.com/crestedhawkeagles.html |website=www.beautyofbirds.com|date=13 July 2023 }}</ref>
