Instructions
Look at the cockatiel's face. Males have brighter colors on their cheeks and faces than females do. The female's face has a washed-out look to it.
Check the tail feathers. Females have yellow and white barred markings on the underside, while males have solid colors.
Spread the cockatiel's wings and look at the underside of the wing feathers. If you see white dots, it's a female.
Listen for singing. Only the males sing. If you're wondering if the cockatiel is a male, separate it from the flock. Males will start singing in about a week.
Talk to your veterinarian about surgical sexing. This method requires surgery, where the vet opens up the bird and examines the sex organs. Surgical sexing is rarely used, unless the bird needs an operation for another reason.
How to Differentiate a Female From a Male Cockatiel
Cockatiels are small parrots that originally come from Australia. Like many parrots, they can be difficult to sex visually. There are many color phases and variations among captive-bred cockatiels, and not all sexing methods work for all breeds. The most reliable method of sexing is through surgery, but it requires the bird go under anesthesia. The most common method of sexing cockatiels is by DNA testing. Sexing the cockatiel using DNA is the most accurate and least invasive method. DNA sexing uses a sample of the bird's blood, a plucked feather, or eggshell from the egg the bird hatched from.
