I too am having difficulty with sexing Forrest, my beautiful talking green and yellow budgie, If you look at my Avatar, it's got a good picture of his/her cere. Can anyone advise?
Forrest can say "Pretty, pretty bird", when I ask 'who's the pretty bird?' He replies "I's the pretty bird", and "Bird's the word" as well as "Give us a kiss(smack)! " He also does something which I think is an imitation of me laughing!!
