Dimorphic Birds

• 1). Check the cere to determine the gender of a budgie or parakeet. The cere is the fleshy area above the beak. The nostrils sit on the cere. Male budgies and parakeets have a blue cere. Female budgies and parakeets have a brown and flaky cere.
  
  Check the cere after the bird is older than a year. Younger birds are too young to have distinguishing features.
  
  
• 2). Study the coat of eclectus parrots. The male and female birds have different colored feathers. Male birds have a green coat and female birds have a red coat.
  
  
• 3). Listen to canary birds. Only male canaries sing.
  
  

Monomorphic Birds

• 1). Check the bottom of the cage for eggs. If your bird lives alone and has eggs, it is a female bird.

  Consult a veterinarian about getting a DNA test done. A monomorphic bird's gender can only be determined through scientific methods. DNA testing requires a blood, feather, or toenail sample. You can get the samples yourself, or you can contact a veterinarian for assistance.
  
  
• 3). Contact a veterinarian about doing surgical testing. A veterinarian creates an incision in the abdomen and can see the sex organs. Younger birds are not good candidates because their sexual organs have not yet developed.
