Hi I'm not veteran, but have asked the vets all of the questions you have.
You should go with a bigger cage, atleast 32x24x30 try AA
www.avianadventures.com and check out the mediana. Playtops and dometops depend on preference, maybe how long birdie is in cage. My bird will be in there 8ish hours so i'm getting a dometop but the nice thing about mediana playtops is they are movable. i know people who have taken the top off to replace it with plexiglass.
supposedly wb males are calmer but many will tell you, it really depends on the individual bird. So if you want a calm one, go ask the breeder, but for caiques calm is not really true! lol
Have you decided on a breeder? Tammy at
www.djfeathers.com and Gloria at
www.shadypines.com are some of the best and highly recommended. Also the caique list is a great place to ask questions
http://groups.google.com/group/Caiques?hl=enThis is gonna be my first bird. Good job for researching caiques before you buy. I reasearched two years and will be getting one in june.
I was thinking pionus or green cheek but after seeing caiques in a bird store, i fell in love, was tyold they are not for beginners, but some nice people told me as long as you want the bird, have done all you can before it gets home, you will do great.
Best of luck on your search! Lauren
