Black Vulture

Along the San Gabriel River, near my home we have quite a number of both black and turkey vultures that roost in the evening in a few specific trees.  During the day, we usually only see them gliding high up in the sky.  I ran into this fellow by itself late yesterday afternoon in a lower branch near the water preening and flapping its wings. I am wondering whether it is one of this years batch of juveniles.  I was able to take some pictures without the usual harsh back-light resulting from aiming the camera to the tree top.
