I have been notified by CA Dept. of Fish and Game that they recovered a lighter colored hybrid falcon near Moreno Valley/Perris California in December. It had jesses and a band, but they have not been able to trace the band. It appears well trained and eats off the rehabbers fist.
The bird is currently at a DFG licensed rehab facility. This is all the information I have at this time but will edit this post when I receive more. Call 714-299-4587 if you think this is your bird.
