Awww, what a beautiful little bird! It's hard to tell from the picture but you seem to have the Colombian or the Venezuelan species - and do you know what they call them in South America? Periquito Carasucia. Isn't that a wonderful name?! Periquito is the diminutive of perico and another name for conure, and carasucia is actually two words: cara (face) and sucia (dirty) so their name, translated into English would be Dirtyface conure
I wholeheartedly agree with Wolf about clipping and I will add something else. I was born and raised in a country where there are wild parrots and, although it's not as common as most people would think it is, there has always been people who kept them as pets but never clipped. The practice simply does not exist. Personally, I think that handicapping a bird by clipping his wings is cruel. It seems illogical to me that people who would never even consider keeping a dog chained to a tree or a horse hobbled for life would consider it perfectly OK to cut the wings of a bird and thereby deprive it of flight. The principle is exactly the same but, for some reason, people don't usually see it that way and I don't know why...
Now, his diet is no good, my dear. Not your fault, of course, but you still need to change it. He can't be free-fed high protein, and dehydrated fruits (which are always treated with sulfites) are not good for him. He needs cooked whole grains and raw produce -and some need to be organic as per the 'dirtiest list' put out every year (grapes and cherry or grape tomatoes been on it). He also needs a large variety so as to round up nutrition. Their natural diet is mainly fruits (berries and more berries as in the kind that grows wild in the countries where they come from like blueberries, cranberries, buffaloberries, acai, etc) but, like every other bird in the world, they love corn on the cob.
