I am so happy to be in this forum with you all

I have 2 Ringnecks, a green male (named 'Pipo') he is 2 years old now.. We brought him at home when he was 1 year old, because we were talking to a friend of ours and he was telling us that he has a ringneck but doesnt have time for it, he was in cage with no attention. He told us if we know someone to take the bird and we decided to take him at home.. At first he was very aggressive with everyone.. but than i started taking him out of the cage every single day and now he is like my baby, he dance, talk, he is a very intelligent parrot, but sometimes he is still naughty and tries to bite

And a yellow one (named 'Cutie') which i am still not sure if it is a male or female. This one was a present from my boyfriend.. when he brought her home she was still without feathers.. she was so cute so I named her cutie

Pipo is crazy about this one.. every where i go with her he comes, thats why i am thinking she is a female. she doesnt have any signs of the ring yet.
My boyfriend has a blue one which is one month smaller that Cutie. He is already showing the ring. He is named ('Rockey').
He is also an intelligent bird.. he makes the noise of the car alarm and started to say 'whats up rockey'..
I am posting some picture of them

From the pictures do you think cutie is a male or female?
