Instructions
Look at the lovebird's body. Generally, females are larger than males but their heads can be smaller. Females will be heavier. A female will also have a wider pelvis than a male. This makes her broader than a male and, as a result, her feet will often be wider apart on a perch. Females usually have tails that look more square, while males have tails that are rounded. A male will generally sit more upright than a female.
Look at the behavior of the lovebird. Females will have a knack for tucking nesting material under their wings and carrying it to their nesting area. A female will also take on the responsibility of doing most of the nesting work. Males often try to do this, but they are not as successful and they drop the materials. This method can be used with a fairly high accuracy rate, according to Avian Web.
Feel the bird's pelvic bone. This should only be attempted by those with experience. On a male, these bones feel closer together than they do on a female. They will also feel pointier. This method does not guarantee accuracy, but some say it works.
How to Tell Male From Female Lovebirds
Identifying male and female lovebirds can be a difficult task. Many species look the same with only a few subtle differences. While nothing can take the place of DNA testing, some people have had success learning their lovebird's gender by paying attention to its body and behavior. Looking for certain specific behavioral and physical differences can help you determine if your lovebird is male or female.
