Mottled Emigrant

I spotted these couping Emigrants by a paddy field and the bank of River Jaldhaka near Hila Tea Estate in Nagarkata, Alipurduar, West Bengal. The River runs southwards dividing India and Bhutan.
How I managed to spot this couple well hidden under a bunch of branches and leaves was due to my curiosity: an Emigrant - something like this male in the spotting - was coming to this bush, hitting at the branches and flying away! On closer look, underneath the bush was this couple! I managed to clear away some of the over-hangings.
