Acquired: Breeder (non-professional, hobby breeder)
Posted Mar 31, 2015
We owned a pair of male Cockatiels for several years. One was grey, the other yellow. Their names were 'Gray' and 'Yellow' (Yes, totally original I know). They were trained to step up and sit on our hands or shoulders. They ate a mostly seed diet.
We had bought them as juvenile birds and had hoped they would turn out to be a breeding pair, but they were both males. We loved hearing them whistle.
We also cared for a client's Cockatiel for a few weeks. It had been previously trained to speak a few words, so it is possible to train a Cockatiel to mimic words.
