It's very difficult to identify European Goldfinch's gender because of its low discrepancy between two sexes, especially before sexual maturation, when males can sing, and other factors, are much more evident.

We are going to fix some reference points to determinate sex of Goldfinch ancestral, as it occurs in nature, without mutations.

Male characteristics:
- Flesh tint red mask transhipped on top behind eye.
- Intense black color and marked
- Strikethrough on wing, yellow well defined and marked
- Over-wing is not dirty brown but clearly black
- Flattened head
- Broad base of the bill
- Well and of course... singing


Female characteristics:
- Faded, less vivid red mask, does not transhipped on top behind eye.
- Not Intense black color, not well marked
- Thin Strikethrough on wing, yellow not well defined and marked
