Some birds feed on insects. It will be very helpful in maintaining the ecological balance by keeping the insect population regulated.
Infact during the Aircel stupid campaign about saving tigeres, there was a study which had showcased its more important to save birds than tigers as without birds not just tiger, none in the food chain below the tiger will exist. So they / telecom was killing the birds and then promoting tigers saving!
Thanks for the suggestion @bobinson. I will try it out.
Yes, it is true that corporates are just doing activities for the sake of doing it and not looking for anything positive in it. Birds play a vital role in planting trees by dropping seeds everywhere. Not just these corporates but there are also other individual bodies, who do researches on Birds and other species. They are also a threat to Birds.
