Thane Creek in Mumbai becomes pink as a massive number of flamingos wade through the waters.
Since January last year, about 120,000 flamingos were found in the city. According to Bombay Natural History Society (BNHS) this is three times higher than their highest population in at least four decades.
Flamingos began migrating to Mumbai since early 1990s; they arriveD in late fall, and stayed until the end of May, when the monsoons began. Typically, between 30,000 and 40,000 birds migrate to the city every year.
However, more flamingos flock in Mumbai this year as they now find more food in the city’s murky green creek.
BNHS said sewage in the creek promotes biological growth of blue-green algae, which is food for the flamingo.
The green color came from algae that became increasingly higher over the years due to the sewer discharges from a nearby water treatment plant, as well as industrial run-off.
The Guardian reported India serves as the home of six species of flamingos in the world, including the greater flamingo and the near-threatened lesser flamingo.
These flamingos usually settle in Thane Creek where one can find around 200 species of birds.
Meanwhile, BNHS also reiterated that massive migration of flamingos to the city in the recent years because of the now “drought-like conditions” in the wetlands of Kutch where the birds usually settle.
