doubletefarm, don't despair. Think about what happened and don't do it again. Start over as if it was day one. Don't be upset in front of Sydney, he will know. Start again. I have rescued an Eclectus, he is a biter and shrieker, among other things. On the first day he shrieked and I sang. Don't ask why he became quiet. For the first couple of days if he shrieked I sang. He has not shrieked for two days. Whether it is my bad singing voice or the cadence of my voice I don't know but it seems to calm Sully. Don't give up, whatever you did to get Sydney to trust you before, do it again and don't give up!!
