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

Females are more active in nesting than males. If you provide nesting material like coconut fiber, dried grass, or soft cotton, females will arrange the nest carefully and prepare it for laying eggs. Males might bring small bits of material, but they do not build the nest themselves. If one finch is spending more time in the nest area, it’s probably a female.
