15 bird species in India critically endangered

  • The latest International Union for Conservation of Nature ( IUCN) Red List of Birds (2013) shows that fifteen bird species in India continue to be critically endangered (CR). 
  • Moreover, three other bird species now face greater danger than before. These species have been uplisted to Near Threatened (NT) and Vulnerable (VU) categories. 
  • Earlier they were better off and classified under Least Concern (LC) category. 
  • In India, organizations such as BNHS-India play a crucial role in researching and collating such information, as the BirdLife International (UK) country partner. 
  • The species falling under the Critically Endangered category in India include:                                                                                                 migratory wetland species: Baer's Pochard, Siberian Crane and Spoon-billed Sandpiper;                                                                                   non-migratory wetland species: White-bellied Heron;                       grassland species: Bengal Florican, Great Indian Bustard, Jerdon's Courser and Sociable Lapwing;                                                                 forest species: Forest Owlet and                                                       scavengers: Indian Vulture, Red-headed Vulture, White-backed Vulture and Slender-billed Vulture. 
  • Himalayan Quail and Pink-headed Duck are now considered Extinct for all practical purposes.
Reasons of decline of bird species in India
  • Drastic modification, fragmentation, degradation and loss of habitat, environmental pollution (both industrial and due to increased pesticide usage), poaching and land use changes, etc.
  • Changes in cropping pattern due to various reasons, including implementation of irrigation schemes, increased pesticide usage, livestock-grazing, high levels of disturbance and developmental activities viz. mining and hydel projects resulted in marginal fall in their population.
  • Drastic loss of grassland habitat over the past decades has severely threatened species viz. Great Indian Bustard, Bengal Florican and Jerdon’s Courser.
  • Destruction of deciduous forests in central India has lead to the decline in Forest Owlet numbers.
  • Destruction of forests in the fragile Western Ghats and Himalaya continue to endanger the existence of many other species.
  • Use of chemical components as in the case of diclofenac’s effect of vulture species.
