Its parents knew where this young one was and continued to care for it. That bit of red showing is not an injury but a berry that fell from a nearby bush.
The nest crashed down Monday morning and as of late yesterday (Wednesday) this young one was doing well, surviving overnights and a couple of downpours. Its parents kept close watch nearby, chirping loudly when we passed to check in.
We will be out of town for a few days, hopefully he will fledge and fly off before we return. And, maybe one day return to raise a family in one of our crepe myrtle trees.
