First of all, how old is your budgie? This plays a role is whether or not you can tell the budgie's gender. The budgie has to be over 1 years old in order for you to tell if it is male or female.
Look at the cere (the fleshy patch of skin right above the beak where the nostrils are located). The cere will be tan or brown for a female budgie, and blue or purplish-blue for a male budgie. If your budgie is recessive peid, lutino, albino, or fallow, the cere will be white or tan on a female, and violet or blue for a male. You can also look at its behaviour to determine its gender. Males often bob their heads, sing, and are usually outgoing. Females are usually snitty and bossy over other budgies in the cage, and tend to be quieter. |
