We have a Sulphur-crested Cockatoo, Long Billed Corella and an alexandrine
The male Cockatoo gets very noisy as he is a naughty 5 year old bird. the noises that he makes goes thru everything, if you have neighbors, they will hate you forever.
The long bill - She is an amazing bird. She is very much a peoples bird but she does have her moments.
Alex - I would suggest a bird like this, don't get a ring neck, get an alex! they have wonderful personalities!
Loris are messy, I have hand raised over 100 of the little buggers and I am not a huge fan, they squirt when they poop and their nails and beak have death grips! they hurt!
Conures are noisy little things too! (mind you it's about 2 months old! LOL)
