Most birds that have been handled by humans and hand fed from an early age respond well to training. Parakeets are one of the easiest types. They don't require long hours of out-of-cage time and are happy with 1 or 2 hours of socialization. They are usually content playing in a cage that gives them enough room and lots of bird-safe toys. Of course, the more time you spend with your bird, the faster s/he will learn.
