changes in eyes. need help with getting one tommorow!

[miami]

I have 2 questions the first:
like humans, parakeets have pupils, but sometimes the pupils in parakeets moove from very small to large very quickly i remember a grey that my friend had, when it was angry its pupil used to thump from small to big very fast continously.. is there any real reason behind why the pupil size changes in the eye. Is it an indicator of any sort for something to look out for?

Secodnly im getting a indian ring neck tommorow for the first time... is there any particular things i need to look out for? signs as such or obvious indicators to the parrots intentions. Also the guy selling it to me said its 3.5-4 months old. Is there any way i can tell if this is true, i heard the eye is totally black at this age iss this correct? when does the bluffing age start... it will be about three and a half months old when i get it tommorow? when do i need to star being aware of the bluffing stage and how long does it last.

thank you

Ringnecks will flash their eyes for so many reasons and it's really neat to watch. I personally cannot get enough of their eye pinning--it's just very fascinating. Both males and females will do this for a variety of reasons. While i was watching some wild ringnecks, i could not help but notice how the contrast of the flashing eyes against the green really stood out. It's almost as if they have solid yellow eyes at times. But as for what it means, i think it's their way of making expressions. We humans have the ability to show our emotions through facial expressions--ringnecks through their eyes. You know when your little green monster is angry as his eyes show it all. When they are excited to see you--their eyes show it all too. It's just their way of communicating and letting you know how they feel.

As for the eye color change--most will start to change around 7 months. When the babies are really young they will be black but as the bird starts to mature, they become yellow. So, you want to look for darker eyes.

The only thing you need to look for is the ringnecks health. If you believe your ringneck is healthy then purchase him/her. The vent, nose, and eyes should not be runny. The feathers should be well groomed and your ringneck should be responsive to your actions.

If the ringneck was well socialized it should just enjoy your company. Though some can be scared and just avoid interaction all together. If you feel you're not compatible, there is always next year or you can purchase one that can be tamed--through lots of love, hard work, and patience i might add .

Hope this helps! Only sorry i could not get on sooner to answer your question!
