The most noticeable increase in the population of the bar-headed geese has shown an increase from 40,570 to 47,598 over the last year's count. According to the Bombay Natural History Society (BNHS), the Pong wetlands are the one wintering grounds in the globe to hold such a large congregation of bar-headed geese. Population of birds and number of species is expected to increase in coming days during return journey to their breeding grounds as birds from northwest, central, and south India will start arriving at the Pong wetlands. Most of the wetlands in India have been regularly getting bar-headed geese every winter, but Pong holds the largest influx every winter, a BNHS ornithologist told IANS. Most of these birds migrate from their breeding places in trans-Himalayan region in Tibet, Central Asia, Russia and Siberia. Over the last few years, the Pong Dam wetlands, a Ramsar site, has become an ideal destination for winter sojourn for many species of migratory birds. /IANS
