That's what this lovely bird is called, in Bengali and other languages. Wiki says this name is because of its "unpleasant" call. I don't find that call unpleasant at all. This bird has a wide repertoire of musical calls - calls that sometimes may even sound a wee bit metallic. It hails from the "intelligent" family of crows, Corvidae.
