Is Your Parakeet A Boy Or Girl?

When I got my two new Parakeets they were young and hard to tell if they were male or female. Well they are now old enough to tell. A male parakeet will have a blue cere, and female will have a white, baby blue, or even a brown cere. The cere is the area at the top of the beak where the nostril is at. At a certain age, it will be easy to tell if you have a male or female. If you have a young Parakeet and want to know if it's male or female, look at the cere and see if there's any trace of white. If you see any white on the nostril area of the cere, that would indicate to me you have a female. I have 3 males Parakeets and 3 females, and my females are pretty aggressive birds, unlike my males.
