Summer heat and the unavailability of food have led to a considerable decline in house sparrows’ population in Thiruvananthapuram city and its suburbs.
The glum scenario came to the fore during a week-long survey conducted by city-based Travancore Nature History Society (TNHS), a non-governmental organisation involved in nature conservation, in the run-up to World Sparrow Day that was observed on Wednesday.
Teams comprising bird enthusiasts scouted the traditional pockets of the bird in places, including Palayam, Kazhakuttom, Vallakadavu, Beemapally, Vettucaud, Kaniyapuram, Pothencode, Nedumangad, and Vizhinjam.
