We have these greater racket tailed Drongos always seen on cables. They sure know to avoid tension wires as if they perch on those there is sure death.
I cannot say peacocks are not intelligent but there was a death recently of a peacock that got electrocutd as it was sitting on a tension wire. We picked it up and buried it in our garden.
No amount of pleading will help protect these birds as our Government is deaf.
Do you have cables exposed like this in your country?
