"On behalf of Expert Village, my name is Laura, and I'm here to talk to you about finches. Sexing finches is relatively easy. In most cases the male of the species is a lot brighter and prettier than the female. In this case, this is the female, pintail whydah, she is brown. The male of the species is white with black wings and very very long tail feathers. Some cases are a little more difficult to sex. The best way to sex your bird is to check the egg area. A female bird will have a very very wide pelvic area and a male bird should have a very small pelvic area. If you still have trouble sexing your bird you can take it to a vet, they should be able to tell you. If not, the next choice would be to have a DNA test done. This is a male pintail whydah. Notice the difference in coloring and feathers. Where the female was a light brown, the male has very bright white and black. On a male in the pelvic area, they will have a very small space between their pelvic bones. Unlike the female who has a very wide space so that they can lay eggs. "
