House Sparrow Population in the City Shows a Chequered Pattern

Travancore Nature History Society (TNHS), the city-based NGO, striving to protect the environment  and create an awareness for up-keeping the rich bio-diversity of southern Western Ghats and its penumbral regions, has been engaged in taking counts of the House Sparrow (Passer domesticus) seen 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. A general trend observed in 2020 was a marginal to significant fall in the number of sparrows over last couple of years in known sparrow hubs like Connemara market, Chalai and Vettucaud regions. Whereas in pockets such as Sulaiman Street and Beemapallly,  there were sharp increase in its numbers.

House Sparrow Population continues to remain precarious in the city - Press Release

On the eve of the World House Sparrow Day, which is being observed annually on March 20, the Thiruvananthapuram-based NGO, Travancore Nature History Society (TNHS) made a numerical estimate of the bird with an exhaustive survey carried out in its known traditional pockets in the city. Members of the Society scouted these locations spread over the nook and corner of the city and its suburbs. Though the abstract number at many locations has shown a fall over and above the figures available for the last couple of years, its subsistence in these locations was found to be on a healthy footing.
