As a matter of fact, they do! It all depends on how the female was raised and how much noise/songs/tunes were around her as she grew up. I had bought a boy cockatiel who never sang; just sqeeked a lot. I proceeded to buy a female and at 6 a.m. every morning she'd sing the same tune for about 5 minutes. Pretty soon the male learned the song. I figured that the girl would soon learn a noise or song before the male, so I taught her how to whistle like someone sexy was walking by, the howl of a wolf and the Star Wars theme song. You can teach them to sing, it just takes time and patience, or maybe you'll get lucky like I did and already have a vocal female.
female
Maybe
sometimes
Depends on the male if it usually goes in the nest then yes
The female and male parakeet do a cloaca kiss and make a baby bird deedadee
you can leave them together all the time
Female parakeet may be aggressive and sighted the bird as a territory threat or vice-versa. Female birds become anxious if they have eggs
I don't think so. I read that adult female parakeets noses are brown and that adult male parakeets noses are blue. But, young female parakeet's noses are "bluish" and a young male parakeet's nose is pink.
a parakeet do no sing get a parrot
Probably when they are very affectionate with one another or you have baby parakeets.
