Practice question

Great Indian Bustard Ardeotis nigriceps is heaviest flying bird, critically endangered with fewer than 150 wild individuals, restricted to arid grasslands of Rajasthan and Gujarat. Desert National Park near Jaisalmer, spread 3162 km² with mixed sewan grass dune, gravel, and scrub, constitutes primary refuge, hosting breeding center run jointly by WII, Rajasthan Forest Department, and IUCN. Bustard requires expansive undisturbed short grassland avoiding tall crops and power lines causing collision mortality, flagship for grassland ecosystem conservation advocacy. Mastery of this rule helps candidates differentiate closely related categories and avoid common errors in diversity questions.
