Why red billed weaver called buffalo?

The red-billed weaver is often referred to as the "buffalo weaver" due to its association with large herbivores, particularly buffaloes. These birds are frequently seen foraging for insects and seeds around grazing animals, which disturb the ground and expose food sources. The name reflects both their feeding habits and their habitat preferences, as they often build their nests in acacia trees found in savanna environments where buffaloes are common.
