You can see the rackets developing on both sides of the tail feathers. The size of the crest varies in the sub species. This is the nominate form found in the western ghats. Not a fan of bird on a stick images but I just like this one.
500D, 55-250, 250mm,Ae, f7.1, ISO800, SS 1/80. Calicut outskirts. C&C welcome
