Size
The olive-backed sunbird is a small passerine bird, meaning it belongs to the order Passeriformes, which includes over 60% of all bird species. Passerine birds are characterized by their small size, perching feet, and ability to sing. The olive-backed sunbird is a relatively small passerine bird, with a body length of only 10-12 cm and a weight of 8-12 grams. This small size allows the olive-backed sunbird to be highly maneuverable and agile in flight, which is essential for its survival in its natural habitat.
The small size of the olive-backed sunbird also has implications for its diet and behavior. As a small bird, the olive-backed sunbird has a high metabolic rate and must eat frequently to maintain its energy levels. Its small size also makes it more vulnerable to predators, so it must be constantly vigilant and aware of its surroundings.

Coloration
The coloration of the olive-backed sunbird is an important aspect of its biology and ecology. The vibrant colors of the male’s plumage are used to attract mates and defend territory, while the more subdued coloration of the female helps her to camouflage herself while nesting and caring for her young.
- Sexual Dimorphism: The difference in coloration between males and females is an example of sexual dimorphism, a common phenomenon in the animal kingdom. In many species, males are more brightly colored than females, as their coloration is used to attract mates. In the case of the olive-backed sunbird, the male’s bright colors are likely to help him attract a mate, as well as defend his territory from other males.
- Camouflage: The female’s duller coloration is likely to help her camouflage herself while nesting and caring for her young. By blending in with her surroundings, the female is less likely to be detected by predators.
- Thermoregulation: The bright colors of the male’s plumage may also help him to regulate his body temperature. Dark colors absorb more heat than light colors, so the male’s bright colors may help him to stay warm in cooler temperatures. Conversely, the female’s duller colors may help her to stay cool in warmer temperatures.
- Communication: The coloration of the olive-backed sunbird is also used for communication. The male’s bright colors are likely to be used to attract mates and defend territory, while the female’s duller colors may be used to signal her availability to mate.
The coloration of the olive-backed sunbird is a complex and fascinating aspect of its biology. The vibrant colors of the male’s plumage are used to attract mates and defend territory, while the more subdued coloration of the female helps her to camouflage herself while nesting and caring for her young. The coloration of the olive-backed sunbird is also used for communication, and it is likely that the different colors of the male and female plumage play a role in mate selection and territory defense.
