Atleast 4000 Wagtails were there during dusk in the time of their roosting. We used to see this huge gathering of Wagtails this time but maximum time it's not possible to id those as they used to be in flight towards their roosting zone. But here in Baruipur, it is the roosting area and it is in between Lane 1 and 2 behind a tea stall. Wagtails used to come here from all nearby areas for roosting. Many of them were sitting on the electric wires and it was easy to id those in this case. I found most of them Citrine Wagtails here and out of almost 500 Wagtails only 40 were White Wagtails sitting in the wires. So, I calculated the whole flock according to this ratio. Some uploaded under Wagtail sp intentionally.
