How can you tell if a parrot is male or female?
Some parrot species are dimorphic ( male and female birds look different)e.g. male budgies have a blue cere (the fleshy patch above the beak where the nostrils are located)and female budgies have a pink or brown cere.Adult male indian ringneck parakeets have a distinct black and pink nape band, and female indian ringneck parakeets lack the nape band , as well as juvenile males. Male and female eclectus parrots are distinctly different, the males are green, the females are red. With monomorphic parrots(African grays, macaws and certain conures) the male and female birds look the same. Some breeders can take slightly educated guesses, but the only truly accurate way to sex these birds is by doing a DNA test, which is quite costly.
An bird breeder (african greys only) once told us that you can tell by looking at the african greys eyes. The males have rounder eyes and the females oval eyes.
Worked for telling ours apart.
I don't however know for other birds. (Unless you are speaking of an eclectus parrot :))
Umm well base on what a man told me some time back, you can tell by the size of their pelvis. Wider pelvis' are females cause they need it for birth while males are smaller.
Other then that im not sure...
