How do I determine the sex of my parakeets? Color vs. behavior.

Updated On September 23rd, 2025

Pet's info: Bird | Parakeet | Male | unneutered

Hi Petco! I was hoping you could help me answer this question that I have been unsure about for a while. I have attached 3 photos below with my parakeets. I am unsure about the sex of each bird. I have been told the green one is a female and the blue and yelllow ones are males. I am very unsure because their behavior makes me think differently. Please keep in mind that the green one is over 5 years old and the blue and yellow ones are only over a year. Thank you for your service.

Going by cere color, I would agree with your assessment of gender. If you want to know definitively, you can have them sexed by submitting DNA samples (feathers or blood) on each bird. Your veterinarian can do this for you. An experienced avian veterinarian can also sex the surgically.
