We had two juvenile Pine Siskin being fed by an adult this morning at
our feeders.  Both juveniles would flutter their wings rapidly and the
adult would bring seed to each.  They stayed for several minutes.   Also
witnessed (and photographed) an adult raven bringing in and feeding 4
young.  They are adult size, trying out their wings, preening, and
seemingly getting ready to fledge.  Rod & Betty Vallee  Georgia
