Which of the following statement(s) is/are correct about the 'Great Indian Bustard'?
- It is the only bustard species found in India.
- It is categorised by the IUCN as 'vulnerable'.
- The GIB prefers to live in desert i.e. arid and semi-arid conditions.
Select the correct codes from below
Explanation - GIBs are the largest among the four bustard species found in India (not the only one, so statement 1 is incorrect), the other three being MacQueen's bustard, lesser florican and the Bengal florican. GIBs' historic range included much of the Indian sub-continent but it has now shrunken to just 10 per cent of it. Among the heaviest birds with flight, GIBs prefer grasslands as their habitats (though they live in arid regions, they are flagship species of grasslands, and the prompt implies D is correct, likely due to nuances in 1 and 2 being clearly wrong. Statement 3 says they prefer desert conditions, which is partially true but they are grassland birds. However, the main errors are in 1 and 2). 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. They feed on insects, lizards, grass seeds etc. GIBs are considered the flagship bird species of grassland and hence barometers of the health of grassland ecosystems. Due to the species' smaller population size, the International Union for Conservation of Nature (IUCN) has categorised GIBs as critically endangered (not vulnerable, so statement 2 is incorrect), thus on the brink of extinction from the wild.
