i'm curious to know how well you birds talk, and their species.
bliss [Cockatiel] knows no words, but he is only 4/5 months old.
delight [GCC] is about one year old, tries to talk, but it sounds like scratchy failure.
lily [umbrella too] knew 19 words coming to us, and learned 5 more in the 3-4 weeks she has been with us so far.
