www.rescueme.org works in both directions. The birds you see in there are described by their human most of the time. Sometimes they also tell personality. You can tell who really loves these birds.
You can put the birds in rescueme with info on them then screen out the ones you don't think will be good for them.
I just went back to them to see if I can get a Lutino female. The whole thing between Shadow, Tommy and Tammy is out of hand. I hope a Lutino female will break it up.
