It's the telephone wire because when birds sit on a telephone wire, they feel as though they are in a second world. Also, they take their bird baths, etc there. They can also go there to get fresh air, so this makes them feel as though they're in a second world.
A television antenna can also work because they also sit on that but the telephone wire is a more effective answer!
ALSO, MY ANSWER IS CORRECT!!!! PLEASE DO MARK ME AS BRAINLIEST! ^ω^
