How to find out if your budgie parakeet is a boy or girl
Over the years I have spent quite a bit of time explaining how to identify a male or female parakeet, so I'm here to pass it along again!
Basically, a male parakeet will have a blue or purple nose (the area right above the beak) and a female will have a pink or brown nose.
While that is simple enough there is a bit of information you need to know! The age of the parakeet is important. I have had a customer in the past who thought they had a male parakeet because of the blue nose but when it matured it turn brown and laid an egg! Most pet store's sell their parakeets young so it may take you a few months to know for sure. I usually take a parakeet about a year to a year and a half to mature.
Another way to know is to have it sex by a vet, which is the most accurate way. Of course, if your parakeet lays an egg one day you'll have your answer then too! A female parakeet will still lay an egg even without a male. Don't worry, it won't be fertile!
