Choosing a name for a pet is a little confusing when not knowing the sex. Budgerigar is a small, seed-eating parrot with a long tail and the informal nickname of budgie. At 3 to 4 months of age, a baby budgie reaches sexual maturity and develops adult plumage. The adult plumage, or bird's feathers, can help to determine its sex. Pet owners can save money by determining the sex of their pet themselves without having to visit the veterinarian.
Determine your baby budgie's age. Age plays a big factor in determining the sex of a budgerigar. If you have a baby budgie, then the bird is still developing its feathers and colour. The colour of a budgie's cere, the bump above its beak, is the basic indicator of sex. Budgerigars have to go through sexual maturity before developing their colour and feather pattern. The female's cere is light yellow, white, reddish or tan and the male's cere is blue. The cere is an area located at the base of the beak, which is the crown or forehead area. It is the nose of the bird and has two nostril-type openings. There are a few exceptions to determining sex by the cere's colour but, for the most part, it's an accurate method.
Look at your baby budgies' cere for the presence of white on it. White is the precedent for the brown shades to determine the sex of a female budgie. Not having a white colour could mean that the budgie is a male. An adult female's cere is made of different colours and can have a pale blue mixed in with the white. The pale blue colour is a possible an indicator that the baby budgie is female. However, the white colour is the consistent colour for determining sex.
Check the nostrils of your pet. If the nostrils appear white, then the baby budgie is a female. Well rounded and pink nostrils are signs of a male baby budgie.
Take notice of its body shape. Female budgies are more round and shapely. Male budgies are slim and tapered. The colour of a cere is not always the only way to determine the sex of baby budgies. There are different colour varieties of budgies such as fallows, albinos, lutinos and recessive pieds. Some baby budgies also have an invisible ring around their nostrils, and males can have round bulblike nostrils. Determining sex using visual methods can be difficult for the untrained eye.
