Ahmedabad: It may not be long before we lose the great Indian bustard forever.The very existence of the bird, which was once touted as a strong contender to replace the peacock as the national bird in the 1960s, is in crisis. As its only habitat in Naliya in Kutch grasslands is being converted to agricultural land and thus would be lost for the bird forever. Union environment minister Jairam Ramesh,in an letter to Gujarat chief minister Narendra Modi on June 9, wrote that the grasslands of Kutch were one of the last remaining pockets that hold promise for recovery of great Indian bustard (GIB).
