Your not going to like my response as IMHO, neither is a good choice!
- Open Top Cage design seriously hurt far too many Parrots and can ever kill them.
- Corner cages look effective for limited space homes, but you will quick notice how small the interior will be when you begin to fill it with support stuff.
Amazons IMHO, need a sizable cage that allows room to open their wings and have tons of interesting things like several hanging toys that double as a something to hide behind while napping.
I have a dear friend that has a full size, Grand Piano in his small apartment. When I asked the question of why? He opened it full-up, plus all the doors in the apartment and sat, then played several amazing pieces and stated: That's Why, I am looking for a much larger apartment!
Why would one place the soon to be Love of Their Life in a What Will Fit Your Space? If the cage is all important, you should likely consider a smaller Parrot. Amazons are not, IMHO, a first Parrot choice for many reasons! Just because you have fallen in Love with an Amazon, does not mean they have fallen in love with you! With Larger Parrots, having them choose you is a much happier way of beginning a life long relationship.
If you are planning on living in this tiny space forever, you really should rethink getting an Amazon. After all they will need to be out and will need to fly.
Sorry, I am an opinionated old guy and have seen far too much during my long and well enjoyed life. Plus being an Amazon Snob. Getting an Amazon to fit a small space does really work well!
Visit the Website: birdcages4less Once there, find the section that provides cages for Amazons. Find a Rectangle cage with a flat top that allow for the play top. Select from only those cages with a full height front door!! You will find it an excellent choice when you go to clean the inside of the cage. Buy extra cups /bowls as you will need them later. Note: 400 USD is not common.
Remember the Cage is for Your Amazon!!
