Hi there - just joined after finding this site while researching parrotlets. I have a pair that I bought a few weeks ago. The breeder showed us the back feathers to indicate who was male and female, but I have a feeling they may both be the same sex. Neither of them appear to have had much human contact, and have only ever eaten seed. For the first two weeks both would go to the far back corner if I approached the cage. I always approach slowly and speak calmly to them. Now that will sit on the perch, but they keep an eye on me and if I move too fast off to the corner they go. They seem to be the best of friends and the worse of enemies. They are constantly side by side, they preen each other, though the one that is supposed to be female seems to do this more often. They eat together, and if one goes to the food dish and the other doesn't follow, there is a tongue lashing. They also go through periods each day where they scream at each other. I tell people it's like an old married couple. They sit together, then they scream and flap at each other, then they sit together again. I've observed the larger one that is supposed to be the female trying to mount the smaller one. When the smaller one does this, it looks like a lazy bird climbing over the other because it doesn't want to fly around. There is a nest box, and I know they have been in it because I see the shredded paper around the cage. Is this kind of behavior normal ? The other thing I've noticed it that they only eat seed. They don't seem to know what fresh fruit or vegetables look like. I put a small piece of carrot on top of the food dish to see what they would do, and they flung it off. I put some greens in but they totally ignored them. The seed blend I give them contains small pieces of dried fruit, but they won't touch it. I even tried some egg food just for a little variety and they ignored that as well. I'm hoping as time goes by that they continue to calm and become more trusting. In the meantime, I'll keep offering veggies like I do to the other birds and hopefully they will start to eat some of it.
