Travancore Nature History Society (TNHS), the city-based NGO, striving to protect the environment and create awareness for up-keeping the rich bio-diversity of the southern Western Ghats and its penumbral regions, has been engaged in monitoring the House Sparrow (Passer domesticus) population in and around Thiruvananthapuram city, ever since March 20 has come to be observed as World Sparrow Day (WSD) in 2010. This year also, during the run up to the Day, members of the Society scouted the nook and corner of the city, noting down the numbers of the birds. It was heartening to note that there was a marginal increase in the number of sparrows in certain pockets of the city, while the number remained steady in the remaining habitats or has gone down nominally. Sparrow count was taken at all known sparrow hubs like Connemara market, Bheemapalli, Vettucaud, Vizhinjam etc.
