K. S. R. Krishna Raju (11 March 1948 – 22 July 2002) was an Indian ornithologist who worked extensively in the Eastern Ghats of Vishakapatnam.
He conducted multiple avifaunal surveys, ringed birds and collaborated with other ornithologists including Dillon Ripley and Salim Ali.
Raju joined the Bombay Natural History Society (BNHS) as a field biologist at Point Calimere and worked with S. A. Hussain[6] and was a pioneering Indian bird ringer.
This relict population was found to be distinctive and was described as a subspecies that named was after Krishna Raju by Bruce Beehler and Dillon Ripley as Malacocincla abbotti krishnarajui.
This was yet another species that gave weight to the Satpura hypothesis suggested by the Indian zoologist Sunder Lal Hora to explain the faunal similarities of Peninsular India and that of Southeast Asia.
