Males usually have brighter colors and sing more compared to females.

Males are more interactive and often try to bond with other finches, especially females. They may feed the female, sing to her, or follow her around. Females, on the other hand, are less interactive unless they are in the breeding phase. If your finch is actively seeking attention and socializing, it’s more likely a male.
