Almost all of the space on the wires has birds sitting on it. If you look again, you will see there are even a couple of birds sitting on top of the post!
But that wasn't all of the birds. Here is another picture.
Mom says it is like this every evening when she drives through there. After she passes this intersection, then it is back to one or two birds.
We suggested that Mom take us to work and we would bark at the birds and chase them away. She said that she probably would not do that. We would lose our voices barking at all of those birds and she thinks they are used to lots of noise if they can stand to hang around a busy intersection in Houston during rush hour.
(Our apologies for the quality of the pictures. Mom was sitting in her car at the stop light when she took the pictures so she didn't have a lot of opportunity to work with the camera.)
