Found this near a village called Raghudebpur (in Howrah district). This bird walks with a distinct style where the tail keeps bobbing up and down.
Does anybody know the name of this bird?

[Edited later: This is a white wagtail – “khonjona”]

I think this is called “ghughu” in local BEngali language.

This was on Thursday at 6 AM. This was taken on DSLR – not my iPhone. I am amazed at the different colors of the sun. I have never seen anything like this. I assume this is due to the differential fog level and different heights – especially humidity right around the trees?
