He's gorgeous!!! Which one is his cage? If its the first picture and as your aviator. I would suggest in a much bigger cage as that one us a bit on the small side.

12 year old blue and gold macaw male
2 year old greenwing macaw
male
Breeding pair of rosey bourkes
Breeding pair of cockatiels
I still say that cage is way too tiny even he's not gonna be in it all the time. The time he have to spend in it and now is nust not good for him. The perch is too small, try to get some natural tree branches. He needs a cage about 4 times the size you have him/her in at the moment.
76x101x189 cm minimum for a greenwing macaw. If he can fully spread his wings, he will beat them up and start to hurt himself. They LOVE to flap, even if they cant fly. Mine flaps multiple times a day. Its their exercise, as well as a show of playfulness.
He looks very tame since you can feed him with your hands. He looks good!
A LOT more toys, larger ones. That toy you have will last 5 seconds with a greenwing in the mood to play. Get rid of that little seed stick on the side, he cant eat that and he'll just bit it in 1/2 and make a mess.
Get a lot of different sized perches, no less than 5cm diameter.
Here is my macaws food setup
Pellets: zupreme or whatever brand in a store near you
fresh veggie mix: bell, zucchini, garbanzo beans, corn, cucumber, peppers, etc.
Seed mix: some seed mix my store had that my macaw loves. Mostly small seeds he likes to pick at for fun
Large nuts: walnuts, hazelnuts, Brazil nuts, pecans, pine nuts, etc.
Always fresh water multiple times a day. For some reason macaws likes to drop their food in the water and stare at it.
