So, he has been making this sound since I got him. The guy I got him from said he never made this sound before. Is this something I should be worried about? I have never heard a bird do this. I have a vet appointment this Thursday to have him checked out. I actually work at a vet (we only see cats & dogs) - one of my vets said she worked at a place that had lorikeets free flying & this was a normal sound. I’m not so sure..... What do y’all think?
