Do you believe, due to excessive radio-waves, the birds like sparrows die?

Its impossible, the waves won't affect any kind of birds because the waves would travel through some high frequency where birds cannot fly that much height. If u beleive that then ur beleif is wrong. Radio waves naturally travels in certain frequency, its not harmful to any living being. It have some layers so the waves travels in between the seven layers. The layers have some proof, so it won't disturb any thing.

Possible. I am not sure.
