So I have been doing some serious research about what bird I want to get. After quite a while, I finally decided that I'm getting a caique! I found a local aviary that sells them for 250 each (a bargain I know). I have done lots of research and know quite a bit about them, but I wanted to make sure of a few things. Firstly, how big should the cage be? I understand that these are very active birds and so will need a large cage, but exactly how big are we talking? Also, is there any difference between the two species other than looks? Thanks!
