What's so great about Bhandup Pumping Station (BPS), a sewage treatment plant off the Eastern Express Highway? From the perspective of wildlife biologists, ornithologists and birding enthusiasts, BPS is a hotspot for birdwatching in the city of Mumbai.

Speaking about the location, Vidushi Jaiswal, freelance nature walk guide who will lead a Mumbai Bird Safari by Hallu Hallu this week, shares that apart from being a route to the Thane Creek Flamingo Sanctuary, it is a wetland habitat where birds are active throughout the day, unlike the forest areas where different birds are active at different times of the day. She adds, “Thane Creek acts as an important bird area (IBA) that witnesses a large congregation of birds. You can spot around 40 to 50 species including over one lakh greater and lesser flamingos.”
