KOCHI: There are still crows, and there are still chicks inside their nests, just like before. However, in many areas where crows were once seen in large numbers, their presence now seems reduced. Bird watchers say this is not due to a population decline, but rather a shift in habitat.

Kerala is home to the highest number of crows in the country. Due to development activities and issues with food availability, these birds are relocating their roosts. A study conducted jointly by the Wildlife Department of the Agricultural University and Bird Count India has come to similar conclusions.

This study, which spanned over six years covering both monsoon and summer seasons, found that, unlike many other birds, the crow population has not actually declined. They are still observed peeking, watching humans, playing tricks, and collecting necessary materials neatly with their beaks.

Why are they changing habitats
Crows primarily feed on leftover food. In the past, plenty of such food was available in the house yards and surroundings. But with urbanisation and the rise of apartment living, this availability has significantly changed. There was strong speculation of a decrease in crow numbers in Bengaluru as well—but that was only due to their migration in search of more suitable habitats. Heavy use of pesticides in farmlands is also pushing them to move to other places.

Crows in Kerala
Two main species of crows are commonly seen in Kerala: the Jungle Crow (Balikakka) and the House Crow (Penakakka). Jungle Crows have entirely black feathers, while House Crows have a greyish neck and head. Their breeding season runs from December to June, during which they lay between 3 to 9 eggs.

Crows live up to about 10 years. The idea that their numbers are decreasing is a misconception.
