I work in a pet store....I know I know.... anyways the last yellow sided conure we had, a mother bought fo her 4 year old daughter. the girl was confident with the bird and that makes a huge difference. My GCC will bite my youngest sister any chance he gets because she played the whole hesitation game when it came to picking him up. GCC are drama queens and if you give them a reaction they like, the behavior they had to do to get the rection will get worse.
With any of my GCC or my similar sized birds, as soon as you show them you are afraid of them, they become afraid of you therefore they dont want to be picked up. intale biting ect.
You also have to remember that around 8-12 months most GCC go though a biting stage, you have to be strong during this time because this is when you will most likely determine the birds behavior going forward. I also find, and this is in my opinion dont austristize me, you have a less nippy bird if their wings are clipped. If they know they can fly up and bite you and fly away they will.
Another thing is if/when you get bit you want to do 2 things.
1. dont pull away, when you pull away you tear skin and you give them a satisflying reaction. you want to push in to the bite, they arent used to this and will usually let go.
2. dont yell at them when they do bite, birds think of yelling as a sort of singing, you will get your point across with a stern ¨NO!¨ and a dirty look. these birds are always watching facial expressions.
My Honey and Conrad were ¨biters¨ when I got them, the only time they bite now is if im clipping their toe nails. they will always play with things with thei beaks, its like their hands. like stated above you just have to let them know when they are playing to hard. And Im sure some people will disagree with some things Ive said, but this is all in my personal experience of working with them at a store and owning 4 myself (all rescues/rehomes).
Dont be discouraged by what you read, I always tell people the negative stands out more then the positive, so you are going to read more negative thigs then positive. these are great birds. Big birds in tiny bodies, full of personality and love. Just make sure you handle what ever bird your thinking of buying/adopting. You want to make sure you and your bird get along. have a coversation in baby talk with them before handling them, helps put them at ease.
