FLAMINGOS - ENVIRONMENT

News: Pink flamboyance

 

What's in the news?

       Every winter, thousands of greater and lesser flamingos fly into Mumbai, forming a sea of pink against a backdrop of skyscrapers, bridges and oil refineries along the 26-km-long Thane Creek, the DPS lake in Nerul and Sewri.

 

Key takeaways:

       These migratory birds generally fly from Kutch in Gujarat and the Sambhar Lake in Rajasthan to Mumbai during winter around mid-November, but due to prolonged rain and other climate factors, their arrivals can be delayed.

       Last year, the Bombay Natural History Society (BNHS) conducted a survey in which approximately 1,33,000 flamingos were observed across the Thane Creek Flamingo Sanctuary, Sewri, Nhava and adjacent zones.

       Flamingos feed on the algae that dwell in the mudflats at Navi Mumbai, Airoli and Thane Creek, and it is the carotenoid pigment in algae that gives flamingos their pretty pink colour.

 

Flamingos:

       The Greater Flamingo birds are the most widely found species among the Flamingo.

       These are long-legged and long-necked birds which are the filter feeders and get their characteristic pink colour from their diet of brine shrimps and algae available in the coastal wetlands.

       Flamingoes are the indicators of a healthy coastal environment.

       The species inhabits shallow eutrophic water bodies such as saline lagoons, saltpans and large saline or alkaline lakes.

       The species nests in large dense colonies on mudflats or islands of large water bodies.

 

Species of Flamingo:

In India there are two species of flamingos such as

1. Greater Flamingo (Phoenicopterus roseus):

       They are widespread in India, and they migrate to South India during winter and spend their time in large reservoirs and mud flats.

       IUCN status: Least concern.

2. Lesser Flamingo (Phoeniconaias minor):

       They mainly breed at the Rann of Kutch/North-western India.

       IUCN status: Near threatened.

       Appendix II of the Bonn Convention (CMS).

       Appendix II of the CITES Convention.

Both these species of Flamingos are resident species and breeds in the Little Rann of Kachchh in Gujarat.

 

Go back to basics:

Thane Creek Flamingo Sanctuary:

       The Maharashtra Government has declared the area along the western bank of Thane Creek as the “Thane Creek Flamingo Sanctuary” since 2015.

       It is Maharashtra’s second marine sanctuary after the Malvan sanctuary and is recognised as a Ramsar site.

       It is recognized as an “Important Bird Area” by the Bombay Natural History Society.
