Great Indian Bustards

  • Habitat: In India, GIBs are confined mostly to Rajasthan and Gujarat. Small populations occur in Maharashtra, Karnataka and Andhra Pradesh.
  • Preferred Habitation: Great Indian Bustards (GIBs) prefer grasslands as their habitats.
    • Being terrestrial birds, they spend most of their time on the ground with occasional flights to go from one part of their habitat to the other.
  • Feeding Pattern: Great Indian Bustards (GIBs) feed on insects, lizards, grass seeds etc.
  • Importance: GIBs are considered the flagship bird species of grassland and hence barometers of the health of grassland ecosystems.

Threats to Great Indian Bustards (GIBs)

  • Power Transmission Lines: WII have been pointing out overhead power transmission lines as the biggest threat to the GIBs.
    • WII research has concluded that in Rajasthan, 18 GIBs die every year after colliding with overhead powerlines.
    • This happens due to their poor frontal vision, as they can’t detect powerlines in time and their weight make in-flight quick manoeuvres difficult.
  • Development of Renewable energy infrastructure: Kutch and Thar desert are the places which have witnessed creation of huge renewable energy infrastructure over the past two decades.
    • These energy infrastructures are leading to installation of windmills and construction of power lines even in core GIB areas, causing deaths of Great Indian Bustards.
  • Change in Land use pattern: Change in landscape by way of farmers cultivating their land, which otherwise used to remain fallow due to frequent droughts in Kutch.
    • Cultivation of cotton and wheat instead of pulses and fodder are also cited as reasons for falling GIB numbers.
