I don’t know a ton about birds, but I do know this: Bluebirds like to perch on posts. If you see something cute and feathered perching on a fencepost in an open piece of land, “bluebird” should at least cross your mind. (Blue feathers should make you a little more sure, although you won’t necessarily be able to make them out, depending on the angle you’re looking at and the bird’s sex.) A few weeks ago I stopped at Manassas National Battlefield on the way back from Richmond and was delighted to see a ton of Eastern bluebirds, many of them on fenceposts.
See that thing on the post near the bottom of the picture? That’s a bluebird. It’s on a fence around a monument commemorating the first battle of Bull Run.
Then a little bit later we were walking down a path and alarmed a bluebird that had just been sitting on a sign – and I was amused by this graphic proof that, indeed, birds hang out here a lot.
I wonder if park employees have to go around scrubbing the signs all the time?
Cool story I just learned from the USGS: In the mid-1800s, as settlers pushed westward and cut down all the trees, Eastern bluebirds proliferated. Clearing out old-growth forests and producing nice open fields and orchards suited them just fine. Also, they liked that farmers fenced their fields with wooden fenceposts.
