It is best to get it one of those hard stick-type foods as a treat, this should allow your parakeet to keep it's beak from growing too large (im not certain that they do this). If this does not remedy the problem I would strongly urge you to take your pet to the vet! Trying to file down the beak of a bird could prove harmful, or cause stress to the bird (then it may molt), not to mention the fact that a scared, and non-sedated animal will likely attack you...in this case possibly taking a good size plug out of your hand.
Parakeets have a beak and the thing above it which is called the cere.
a cere
Right above its beak.
no, I have budgies/parakeets and have never seen that, and from what I've seen it's not possible.
No!
Take them to the vet. Feel better!
Parakeets do not have teeth, they have a beak and a tongue.
If a parakeet's beak is blue, it's a boy. If it's red/pinkish, It's a girl!
Parakeets do not become pregnant, they lay eggs. Females have a pink or tan color nostril band.
NO they definitely can not. There beaks are way to small and fragile. The beak would break on contact.
A little further back from where the beak hinges. It is just a hole on each side of the head
Parakeets breath through their cere, The small but cute set of openings located above their beak.
