Sudhir Vasudeva, CMD of the Oil and Natural Gas Corporation (ONGC), on Tuesday launched the ‘Save the House Sparrow’ campaign to mark the 57th ONGC Day at Tel Bhavan here.

The campaign, initiated by ONGC in association with Action and Research for Conservation in Himalayas (ARCH), a local NGO, aims at the conservation of the dangerously dwindling house sparrow population in the locality and the surrounding region.
