I looked into the mystery of the gray catbird’s rusty rump. I mentioned the rusty colored feathers under its tail feathers in yesterday’s post. For some reason the underside of its tail feathers looks a little messy. I was able to get more video evidence about what might be the cause.
The catbird looks fastidious. That may be misleading. Scientific observation reveals what is really going on.
This is probably also the origin of an old saying. I think it was Plato who said, “Never stand under a bird.”
