This is an update on my post titled ‘The Chirpy Sparrows’.
I recently got a chance to observe sparrows up close again as there was a nest with chicks that was out of view. The parents were making several trips with food and so I got to see what they were feeding the chicks. I discovered that they were mainly eating insects as can be seen from my pictures.
Earlier, I had suspected their numbers were falling because of pesticides and insecticides. But now, I have the evidence that insects form a major part of their diet.
So, could this be the biggest reason for the fall in their numbers? What do you think?
