It could be that your parakeet is showing affection or that he/she is scared. I let my parakeet bite my nails to show that I am not here to attack him. When I call her name she flies right to me. :O)
Parakeets bite for many reasons. Did you just get your parakeet and he is scared? Perhaps your parakeet is very protective over a certain toy. It could also be because they are pregnant or are protective of it's other parakeet friend. Are you feeding your parakeet? Cleaning his cage, feeding him things other than seeds? You have to put yourself in your parakeets shoes, because depending on an individual bird they may bite for various reasons.
My boy parakeet seems to be feeding the girl. What does that mean and is she getting all her nutrition she needs?

It could be a mating ritual - you don't mention the age of the birds. Google information about parakeets or Google parakeet breeders & contact them as they are full of useful information.

I have a parakeet and when I take her out of her cage I watch her and she starts to move her beak like she is speaking, but no sound comes out. What is she doing? I have two other cockatiels and they do the same thing. What does it mean, what are they doing?

We just bought a parakeet yesterday and brought him home. Since then he has not chirped, vocalized, eaten, or drank much. He is not preening. We called the pet store and the guy said that he is just nervous and acclimating to his new environment.
He does not appear ill, but he is not doing much of anything. He can fly from perch to perch for example when he is scared, but mostly he stays in one place like a statue. Do these behaviors most likely mean he's just nervous? And if so, do you have any suggestions?
