Black-rumped Waxbill: Small songbird with conical, red bill, a long, narrow red mask and a gray eye ring; mostly pale tan and gray, finely-barred plumage with white coloring on cheeks, throat, vent and edges of outer tail feathers; rest of tail and rump black; dark brown flight feathers and purple-brown to black legs and feet. Sexes similar, but males are tinged pink on underparts. Juveniles are similar to adult, but have paler, duller underparts and have a black eye stripe and a black bill.

Breeding and Nesting

Black-rumped Waxbill: These birds generally build a new nest for each clutch. They build a nest close to the ground, or in some instances on the ground in long grass. Four to five eggs are laid in the dome-shaped nest. The nest is made of grasses and coconut fibers, and includes an artificial, cup-shaped nest on its side. Both sexes incubate the eggs.

Foraging and Feeding

Black-rumped Waxbill: Their favorite foods include mall-grained millets, insects, ant pupae, green aphids and fruit flies. Live food is essential especially at breeding season. Small mealworms, small crickets and small locusts are ideal. They also eat sprouted or soaked seed if available. They use their conical bill to forage for grass seeds and small creatures on and near the ground.


Black-rumped Waxbill: A short warbling song of nasal squeaking sounds that has a loud note followed by a descending note, "tche-tcheeer!" or "chee-eeer!" Calls include a harsh "chuur", "chew-tch-tch", a nasal "jeeeu", and a rising "chihooee."

Located on the wing, and collectively called remiges (singular, remex). The long stiff feathers are subdivided into two major groups based on the location and are called primaries and secondaries.
The area between the uppertail coverts and the back of the bird.
Birds do not have two separate cavities for excrement and reproduction like humans do. In birds, there is one single entrance/exit that suits both functions called the vent, cloaca or anus.
