Gender identification of peony parrots can be carried out through several methods: Morphological observation: The gender of adult peony parrots can be identified by observing their body size and head shape. Typically, males have a pointed head and a slightly smaller body, while females have a rounder head and a relatively larger body. Plumage Color: In some peony parrot species, there is a difference in plumage color between adult males and females. For example, in some blue morphs, the male's blue color is usually more vivid, while the female's color is lighter.

DNA gender identification: This is an accurate method that can be carried out by collecting a small amount of feathers or blood samples. Genetic analysis to determine gender. This method works for peony parrots of any age, including young birds.

Endoscopy: A professional veterinarian uses an endoscope to examine the cloaca of a parrot and observe its internal structure to determine the gender. The opening of the cloaca is round in females and oval in males.
