Kiwi has been through 3 cages since we’ve owned him, each a different shape and size and color than the others. In addition, he has also had 2 playstands, 3 travel carriers and 4 different styles of portable perch. He has never had any issues taking to his new cages, stands, carriers or portable perches. This last cage was from birdcages4less.com and I really recommend you look there. They have a great cage selection and it’s held up much better than the other powder coat cage he had. I expect a good 5-8 more years of service out of this one. I also have to say, this cage is white and by far my favorite color. The cage feels so much more open and airy than his prior cage did (which was black). Go with a lighter color if possible.
Just wanted to get into a little about the wider than tall thing- with big bird cages, you don’t find them wider than tall, unless maybe some aviaries might be close in dimensions. You also can’t really follow that 1.5-2X the wingspan “rule” either when your bird has a roughly 28” wingspan (or bigger for Big Macs and cockatoos). As a big bird owner, I’m limited to taller than wide cages. I know you have a smaller bird, but I just wanted to give firsthand experience that my bird uses every inch inside and out of his taller than wide cage, top to bottom. I know not everyone has room for a wide cage either, 32” is really pushing what we can offer space wise and I know some small bird owners, the space the bird would take up was a consideration when choosing their bird. Kiwi doesn’t just use the top half of his cage while the bottom half collects poop and cobwebs. His cage is 32x24x62. The lowest perch is only about 12” off the cage bottom and he sits on that branch to preen sometimes, he also goes down to the floor to retrieve fallen toys and treats and slides down the outside of his cage to the very bottom (about 8” off the floor” to say hi to us and see what we’re up to when we’re on the floor. I have found if branches and toys are offered at every level of the cage, birds will generally (eventually) explore every level of the cage. It’s we humans who tend to put branches in the top 1/3 and leave the rest barren, giving the bird no reason to use the entire space. Obviously, getting the largest, widest cage you can is always the best bet, but don’t feel bad if you choose a taller cage due to space constraints or cost or something. As long as the bird can comfortably open it’s wings with plenty of room to spare, the bar spacing is correct and there aren’t any obvious safety hazards, whatever you choose is fine. Any additional width you can fit into your space is a bonus, but not 100% necessary.
