Yes. Take it to a vet for ANY injuries. They are one of the most fragile birds. Almost anything can kill them.
So the male Parakeet has a blueish cere, and the female has a pinkish brown cere. Here is a bad picture of what it kinda looks like
yes
sexing a budgie is relatively easy. if the bird has a blue cere its a male if it has a pink or brown cere its a female
if you said brown cere that is a female
a boy.
The spot at the top of the beak called the cere is blue on the males.
If it is to swollen it might have an infection otherwise it should be fine
a male parakeets cere is dark (dark purple blue ect.)
The male (Boy) parakeets have a BLUE nose/cere (right above the beak) and females have a PINK or BROWN nose/cere, and babies are white, purple or in between so you will not be a ble to tell until they are older. you can google it just tipe in "Pictures of male parakeet" and when that comes up google "female parakeet pictures" and you should see what they look like
Males have a purple to dark blue colored cere (nose) and females have a white to light pink to brown (when ready to breed) cere.
It could be due to a secretion from the nostrils resulting from a cold, a fungus growth or a species of mite which attack the cere. A veterinarian can determine the cause and treatment of.
I would say that your parakeet is probably a girl. I did a lot of research on parakeets sexes and about training them. I am a parakeet expert and I know a lot about them. I am very certain that your parakeet is a female. A males cere is white with a tint of blue and pink. --Hope I helped Dr. M.C
