Eastern Bluebirds are generally birds of the countryside. For example, in Wichita Falls, you see them in the county but not inside the city, and the "city" isn't really all that urban. I have seen occasional bluebirds in Lake Wichita Park, but that is pretty much it.
We're on vacation and got stuck in a traffic jam in Atlanta (I-20 E, just outside the Loop 285) and decided to pull off as soon as possible and find a motel for the night. As my husband is checking in what do I see? I had to get out my binoculars to be sure, but there it was, a male Eastern Bluebird at the side of the road.
In addition to the bluebird, I saw a brown thrasher carrying food to its young. Two good birds for anywhere, seen in Altanta, GA.
