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.

Exotic butterflies come calling - Article on The Hindu newspaper about Baiju K's & Kalesh S's work on Trivandrum Zoo Butterfly park (June 20, 2014)

The Red Pierrot warmed up quickly to its new ‘hosts.’ This striking little butterfly fluttered around the new plants in the Thiruvananthapuram Zoo, brought here only a couple of hours ago on Monday morning. R. Baiju watched, almost endearingly, as the unusual butterfly species finally adopted a leaf as its home, or egg-laying spot, even before the plants were taken out of their bags and planted into the soil.

He is a Hindi teacher of a government upper primary school in Palode but he was on leave on Monday to engage in a serious hobby of his. Mr. Baiju is one of the more active members of the Travancore Natural History Society (TNHS), the group that is supporting the city zoo in its endeavour to transform the neglected ‘Butterfly Park’ on its premises.
