Birds in India are gradually going extinct due to loss of habitat


India is home to at least 1,168 bird species and has been ranked the ninth in the global list of bird wealth. Kerala, one of its southern states, boasts of some 500 species and, 24 of them come under the various threatened categories. This has been revealed in a book "Feathers of Vellayani" - it is a publication of the Kerala State Biodiversity Board and it says that the largest threat to Indian avian diversity was habitat destruction.
This has been reported in zeenews.india.com dated 21 April 2016.
The blame for depleting bird resources is attributed to the loss of forests, plains and other natural systems to agriculture, mines, urban development, draining of swamps and other wetlands - all these are factors that reduce potential habitat for many species.
Moreover, unfair alteration in habitat due to introduction and invasion of exotic species is another major threat to birds while path-barriers claim millions of migratory birds every year.
Notwithstanding these, there are poaching, predation, weather and other natural and anthropogenic barriers that prove detrimental for birds. In short, the bird population is threatened as never before.
Vellayani Kayal is a lake that is a vast picturesque rain-fed lake surrounded by lush greenery and situated to the southeast of the Kerala capital. It has birds like Lesser Whistling Duck, Blue Rock Pigeon, Asian Koel, Indian Cuckoo, White Breasted Waterhen, Great Cormorant, Painted Stork, Indian Pond Heron, Cattle Egret, Pacific Golden Plover, Common Sandpiper, Greater Spotted Eagle, Brahminy Kite, Barn Owl, Small Bee-eater, Lesser Pied Kingfisher, Amur Falcon and Rose-ringed Parakeet.
The uniqueness of the lake is its topography which is always water logged and the vast expanse of wetlands bordering the lake has marsh, ponds, swamps and fields. In the opinion of experts, there are more than 125 species of birds, including migratory ones, that frequent the Vellayani lake and adjoining wetlands.
