A panther

I saw some green parakeets, black head and yellow tail, size of am comon indian green parakeet today on my way back from Jari. Some locals told me there was a panther nearby, actually throwing stones at the presumed location of the beast to scare it away. The only thing alive i ever saw up there was a Rhesus Macaque and the stupid monkey seemed quite unnerved by all the commotion.
