One more bird post and I will try to hush
. . Handfed birds are usually the most even-tempered birds and they relate to people better because they have grown up with them. Bird that are raised by their parents and with other birds tend to remain afraid of humans. Knowing a bird's history can be really important to your experience.
I'm not sure what age of person the pet will be for but birds can bite (Damage varies by intent, bill type, and bird size). My tiel was a handfed chick and she loves people. She can't really bite but she can get really loud. The keets were raised by their parents so they do not interact with humans at all. They sing, play, and keep each other company. The parrot is bonded to me only and has a mean streak. He can bite and do damage to humans, rugs, wood baseboards, etc. (I bought him as a third owner so I'm not sure that his early life history is very good. He needed disipline somewhere down the line that he did not get and training too. We tend to go a few rounds every now and then until he decides to listen to Mama.)
