Red-billed Buffalo Weaver

Overview

The red-billed buffalo weaver (Bubalornis niger) is a species of bird in the family Ploceidae found in eastern and southern Africa. It is considered the largest of the weaver birds and is currently listed as Least Concern on the IUCN Red List.

Identification

• Body length ranges from 21 to 25 cm, making it potentially the largest member of the weaver family.
• Males have dark chocolate brown plumage with white-flecked wing edges and a red bill; females share the brown body but lack the white wing flecks, featuring broad white hems on the chin and throat instead.
• Males possess reddish-brown feet and brown eyes, while females have light brown legs and dark brown eyes.
• Adolescent birds are a lighter shade of brown than the adults.

Habitat

This species inhabits dry savannahs and sparse woodlands in eastern and southern Africa. It prefers areas disturbed by humans and livestock, often nesting in thorny trees or windmills near human settlements, and will depart if the local human population leaves.

Diet

The diet consists primarily of insects, seeds, and fruit, including specific prey such as crickets, locusts, grasshoppers, caterpillars, beetles, weevils, wasps, bees, ants, flies, spiders, and scorpions. Foraging is conducted mostly on the ground, where most of these food sources are located in the soil or low vegetation.

Did you know?

Males possess a non-functional pseudo-penis, roughly 1.5 cm long, which lacks blood vessels and does not carry sperm but is favoured by females for pleasure and aids in attracting mates. This organ is often larger in males living in colonies, suggesting it has evolved partly through male-male competition.
