Hailing primarily from South America and Central America, sun conures are magnificently iridescent birds with limited language capability. Sun conures are monomorphic birds, meaning it is essentially impossible to determine their genders by sight. But there are a few methods by which you can sex sun conure species.

Sun conure: how to tell gender
These birds of colorful plumage — yellows, oranges, and greens — measure just a foot in length fully grown but have enormous personalities. By appearance only, it is improbable that you'll be able to tell the difference between a male sun conure and a female one. If you're the proud owner of only one sun conure and you suddenly discover an egg in your winged friend's cage, you can be sure your sun conure is a female. Keep in mind that the birds aren't sexually mature and fertile until they are at least two years old.
If an egg suddenly appears and your cage is occupied by more than one bird, determining which bird laid the egg is obviously more difficult, especially given that both male and female sun conures are inclined to sit on an egg during what would be the incubation period if the egg is fertile. An infertile egg among two birds might mean you have two females, but not necessarily.
While adult birds have the same coloration, when the feathers first grow in on young birds, you can tell the difference between genders. When the feathers grow in on a female bird, they are the same bright red that she will have as an adult. Males, on the other hand, initially have fewer red feathers and develop the red coloring as they mature.
Sun conure behavioral differences
One trait of the male sun conure is a territorial approach to his cage and to human companions. Female sun conures tend to be more affectionate and sociable. The male may be more talkative than a female, and his screeching might be more persistent. Screeching is a common trait with all conures, male and female, which means it's not a terribly accurate determination method.
Surgical sexing sun conures
A veterinarian can surgically sex conure species. The vet will anesthetize the bird and pluck away a few feathers, then make a tiny incision in the bird's abdomen. Then the vet will insert an arthroscope into the incision to search for a single ovary on the left side of the body or a pair of testes. This method has a higher accuracy rate but carries risks with the administering of anesthesia and the possibility of post-surgical infection.
DNA testing for gender
Your sun conure isn't likely to commit a crime, but his or her DNA is as precise as any utilized in law enforcement. DNA testing is as accurate as surgical sexing but poses less of a risk. Your bird groomer or an avian vet can extract a small amount of blood by clipping a toenail slightly shorter than normal and squeezing the toe. The blood sample is then submitted to a lab that will determine your pet's gender.
Sun conure male vs. female
Unless you're planning to breed your sun conures, the sex of your bird might not be of great concern. You might be content to sit back in patient wonderment to see if Randy lays an egg and becomes your Sandy.
