Why do pigeons (rock doves) and mourning doves as well as some other bird species line up on electric wires?
Some in my family claim it is because the wires keep their feet warm. Others dispute that theory but offer no better explanation.... (e.g. the view, because the rest of their family does it, the wind direction etc.)
As these disputes can become quite heated I thought I would toss it out to the list for any real data or a better theory that others may have.
