Or should i just learn more and get more expierience handeling them?
This is strictly coming from -my- experiences as a person who has worked with parrots (of all sizes) for about 5 years.
If you are educated with parrots, have experience handling parrots, and have a large support system (parrot clubs, breeder support, etc), I don't see why you cannot have a Caique.
Yes they are headstrong
Yes, they are beaky
Yes, they become overstimulated and can have "black outs" where they get aggressive and nippy.
Everything with a mouth bites.
If you educate yourself, indulge in every forum, book, and website and take in every ounce of research, you are setting yourself to be able to handle situations such as overstimulation. In my opinion, Caiques are lovely birds. They may bond with one specific person, but I have yet to meet a Caique (that is properly socialized) that isn't accepting of strangers, and I have yet to meet a Caique that has bitten my face (though my hands have been shredded before because I hadn't learned body language yet).
For a lot of people who adopt Caiques, they adopt them because of their accepting and loving nature to current, and new members of the family.
Parrots are parrots. You need to be educated before getting any species. In my experience, I would never recommend an Amazon because to me, they have shown tendencies to be exceptionally aggressive at time of sexual maturity (and when they are aggressive, they literally aim to shred), however I know people who have had different experiences with Amazons will look at me, shake their head, and say "my experiences with Amazons have been perfect" (and I will envy them because I love Amazons, but I have just had bad experiences).
Caiques have nasty bites. So do Conures. So do Parrotlets. So do Macaws. So do Amazons.
My worst bite, where my skin was peeled, was from a GCC.
If you are willing to do your homework, and set yourself up for success, then I don't see why you couldn't have a Caique as a first bird. Please read that sentence carefully: you must do your homework. If you have pet stores around, or parrot clubs, anywhere where you can have access to handling a Caique, do it. Handle any parrot you can, actually. Go to pet stores, get bit, realize what you're getting into. Call breeders, CALL CALL CALL. Ask questions, take notes, save valuable information. Expose yourself. Creep these forums. Creep facebook parrot groups (for example, here in Canada we have a Canadian Parrot Association), educate yourself.
You can be a fourth time bird owner, and completely mess up your Caique's home life because you didn't educate yourself.
You can be a first time bird owner with a happy, healthy, well socialized, and well mannered Caique because you realized exactly what you were getting into, and learned how to work through road blocks.
Maybe I am biased because I personally have only worked with parrots, never owned one, and I plan on getting a Caique or a B&G Macaw, but I know a lot of breeders who have told me it isn't about how many birds you have owned, it's about how knowledgeable you are when it comes to parrots in general.
Know that every species has a quirk that you need to decide if you want to work through it. Like people, every individual parrot has a flaw.
Good luck in whatever species you plan on researching
Just please take one thing away from my response: EDUCATE AND EXPERIENCE.
