Why in news
Ecologists and bird-watchers reported a significant increase in winter migratory birds in the Nilgiris, including the first-ever recording of two bunting species.
Background
Ecologist Chandrasekar Das (Keystone Foundation) and bird-watcher Murali Moorthy documented the presence of Grey-necked Buntings and Black-headed Buntings in the Nilgiris. The increase in birds of prey, such as the Greater spotted eagle and Steppe Eagle, is attributed to harsher winters in home ranges or improved food availability in the Nilgiris.
