The beak of females is wider at its base.
The head of the females is usually round, while the males have a slope between the forehead and the rest of the head.
The females have a more reserved character (they are more aggressive), they tend to defend their territory.
The female is the one who puts almost all the material in the nest, the male can occasionally help her.
Roseicolli females keep nest material between their plumage and thus transport it better, males do not.

Males are smaller than females, but the pose they take on perches and poles makes it appear larger.
We can differentiate the male from the female by feeling their pelvic bones, the females have it further apart. We must carefully touch the pelvis of the birds.
The male does not participate in the incubation. Although occasionally in the nest he usually feeds the female, while the female leaves the nest very little, only to drink water and eat.
During breeding the female sleeps inside the nest, while the male perches on or near the nest door.
