It is also called crested honey buzzard with scientific name as Pernis ptilorhynchus. It is a bird of prey in the family Accipitridae, which also includes many other diurnal raptors such as kites, eagles, and harriers.
It is quite big raptor with a long tail. It’s head is very small like that of pigeon. It is a specialist bird feeding on the larvae of bees. It also consumes crumbs of the honeycomb. Additionally it take cicadas.
It’s flight is very stealthy. In a forest it is possible to spot it only when it is perched on top of very lofty trees.
Again I spotted it quite a number of times in the forest near my home. Here are some pictures.
