Parrots have bright colours, orange, red, blue, green and even some pink. Male parrots sometimes have a ring around their necks. Some parrots can have darker feathers and some have a little brown on them.
Maybe
female
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
A female frog has a bigger body.
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.
Probably when they are very affectionate with one another or you have baby parakeets.
