The mighty Heera marches through a slum chewing bamboo, oblivious that freedom from life as one of Delhi's last six elephants at work could be just around the corner. Fifty years ago, the capital housed more than 200 elephants, covered in garlands and carrying grooms to weddings, or being sought by the faithful for blessings at temples. But now the city -- overcome by cars and rising pollution levels -- is no longer a suitable home for the animals. Now, after years of pressure from activists who accuse the animals' owners of flouting wildlife regulations by keeping them in a city, authorities have ordered the seizure of the elephants. But they warn it could take months to find a new home for them, since authorities are struggling to relocate the elephants because four are sick.
