Birds on a Wire?

Asked AnsweredI have always wondered why birds sit on wires? I used to think that it was to keep warm but I have noticed that they do it in the summer too.

The general consensus is that they huddle together for protection from predators, which is why they are in a group. It is likely that they sit on wires because, like tall tree limbs, they are easy to get to and they can hold multiple birds. Birds do not get shocked because they are not good conductors of electricity.
