It depends on the type of bird. With some there is a color difference, sometimes size is a factor, males of some species tend to be more vocal. With a pet bird, the only absolute way of knowing is with a DNA test. I believe it runs about $40. I think there is an over the counter test that you send in to be tested or a Vet can do it.
