Caiques Gender identification
Methods of Gender Identification:
Caiques gender identification is accurately carried out only through either DNA or surgical sexing. There is not any significant difference in appearance or behavior of male and female Caiques.
Usually compared to males, the female Caiques have white frosting on the yellow cheek coverings and they also show an increased interest in calcium sources, mineral supplements and protein rich foods such as meat or eggs. Males are more aggressive as compared to females. These are slight differences between the two genders but cannot at all be used as a complete measure to determine the gender; it is completely unreliable way to identify sex type of bird.
Some of the reliable methods for this purpose are:
- Medical Examination of the Pelvic Bone
One popular but unsuccessful method performed by bird breeders and owners is medical examination of the pelvic bone of the birds. As compared to male Caiques, the pelvic bones in a female will be wider and shift to allow more area for the egg. This method is not safe for young birds and the pelvic bones of a female do not move until they are ready to start the process of laying eggs which is around two to four years of age when the female Caiques become sexually mature.
- DNA Sexing Test
Another new and owner recommended method is DNA sexing. This procedure is not aggressive and is carried out either drawing a little blood (2-3 drops), which can be done by slightly clipping the toe nail beyond the vein, or by plucking a few feathers from the chest area, which is not very painful. The blood samples are sent to a lab and then the DNA from the samples is used for Caiques gender identification. This is highly accurate and safe, thus recommended.
- Surgical Sexing
This process can be painful and may even be dangerous, thus not recommended. A cut is made in the muscle to carefully examine visually by allowing and moving a scope into the body to locate the reproductive structure. Although this method is accurate it is not preferred if owners are considering breeding since they want to make sure that all reproductive organs are functioning properly.
