Technically, what Ricky needs may not necessarily be *MORE* attention, but rather, *MORE* independence. If he's relying on humans so much to stay happy, then he needs to know how to be more independent. He needs to fulfill his own needs and desires without relying on humans so much.
This is more along the lines of independent play, foraging and keeping himself busy. If he could be taught to wear a harness, then going for a walk with him outside may also be a great way to expand his world.
Training new behaviors can also be a fun way to engage his mind. Trick training, in other words! Target training, station training, turn around, 'big eagle', dance, shake head yes/no, stick out tongue, roll over (sideways or forward), fetch, etc. These behaviors can keep his mind thinking and help 'tire' him out, mentally speaking.
I would urge you to speak with someone such as Barbara Heidenreich, Lara Joseph, Pamela Clark or anyone of their caliber. However, I would urge you to avoid Bird Tricks and Parrot Wizard. (not near the same level as the first three I mentioned)
