The Yellow-billed Oxpecker occurs in savannas with large mammals. In the southern African accounts, hosts bearing ticks are described as essential to its presence.
In flight, its pale-buff rump, present at all ages, helps distinguish it from the Red-billed Oxpecker.
The southern African account reports nesting in tree cavities in dry deciduous woodland and occasional roosting on mammal hosts outside the breeding season. In Kruger National Park, African buffalo and giraffe were often recorded as hosts.
