My conure of 3 years has always been sweet and somewhat sociable. But i noticed lately hes been rather skiddish around well, everything. He would normally walk around tables with no problem, but once he sees an item he doesnt recognize( like a soda can ) he freaks out. Anyway to get him accustomed to things? I should mention he has his flight feathers. I did read somewhere that birds that are clipped are more calm is this true?
