Reddit mentions of Prevue Pet Products Empire Bird Cage, X-Large, Black Hammertone

Get him a new cage asap. It's far too small, plus it's round which can contribute to their stress and anxiety (they need corners to feel secure). Something like this.

Get him plenty of toys, macaws are highly intelligent and will get destructive if bored. Also keep in mind he's going to need a lot of attention, the bigger parrots are basically toddlers in that they're loud, needy, but learn fast, and can be charming. Be careful of him bonding to you, if this is just temporary, it'll be devastating to him if he's taken away. I don't know about macaws specifically, but a lot of parrots when stressed and unhappy will pluck out their feathers, it's essentially like humans cutting themselves. And definitely keep him away from your parakeets, he can easily kill them. Singing to each other from their cages is one thing but I wouldn't let them interact other than that. Best of luck.

Thanks!

Its a Prevue empire macaw cage

Linked to Amazon for details but can be found cheaper if you search around.
Very easy to setup

We got our lovely girl from a rescue. We originally went for an african grey but after several visits she just won us over. Definitely go with a rescue that allows you to meet and learn about their birds, it is such a huge factor. Baby personalities will change, but an adult bird knows who they are.

We got the absolute largest cage we could afford, which is taller than my 6'3" husband, though we really wanted to get this awesome massive corner cage.

Many cockatoos are absolute woodchippers, our girl included. Our little goffin's only likes easy to shred paper and cardboard though, so it depends on each bird. These toys get EXPENSIVE if you don't make them yourself. Our U2 is content to chomp untreated wood blocks we buy at the home improvement stores and chop into smaller pieces.

Food is important to. A high quality pellet, plus fresh fruit and veg, is a must. A steady diet of seeds will shorten your bird's lifespan massively.

An air filter is a must, a stinking good one. Cockatoos are dusty! We went with the austin brand, and we're not disappointed.

They are NEEDY. They scream, and they scream LOUD. Our U2 makes our ears ring sometimes, the goffin's is quieter but she screams more often so it's still rough when you need a quiet moment. They want your undivided attention. Some get bored easily, but can be taught to keep themselves busy if ample toys and distractions are provided. They are destructive. A bite from a cockatoo can get you stitches easily. You can't punish a cockatoo (our really any parrot) the way you do a child. They can be taught, but it takes excellent, darn near perfect, consistency and kindness to reduce things like screaming when they just do it to do it.

Also keep in mind... exotic veterinary care is so dang costly. We just spent 3k on saving our U2 when her oviduct twisted and trapped an egg she was trying to lay. She had to have a blood donor due to her particular situation (which the rescue she came from provided, bless them) and it took over a week before she could come home. The day we realized she was in trouble all of the most trustworthy avian vets in our nearby area were out of town or unavailable and we had to drive 1.5 hours one way to get to someone who ended up giving her excellent care. Plus, many don't enjoy taking meds so the follow up antibiotics were... fun.

All in all, we adore our birds. In general they can be fun, funny, sweet, comforting, and if you get a rescue you can make sure you bring a bird home that fits your personality. They are a TON of work and a huge investment in both money and time. Find yourself a rescue and start meeting birds, stay a while if you can. You will learn quickly if you're ready.
