I'm trying to finger out how this guy works!
Take the tail off an airplane, and by moving the c.g. forward and reflexing the trailing edge, you can make fly.
What options would a bird have to do this?
I first saw this guy August last year, and just a day or so ago. Appears to "raven" with the best of them.
I would have expected an injury to have healed with a partial (at least) recovery of the tail feathers, but there's not even the bump where tail feathers grow from!
