How to Tell the Difference in a Male or Female Cockatoo
Determining the sex of a cockatoo is challenging at times. Determining the sex of a younger cockatoo is even more challenging because some breeds do not completely develop their colors until they are 3 or 4 years old. The Bare-eyed (or Little Corella), Ducorps, Goffins, Palm and Slender-billed Cockatoos are the most difficult breeds to sex and should be done by an expert or through DNA testing. However, looking closely at particular characteristics in certain breeds can help you discover if a cockatoo is male or female.
