Southern Yellow-billed Hornbill

The Southern Yellow-billed Hornbill is a familiar medium-sized hornbill of southern African bushveld, easily identified by its long, curved, bright yellow bill set against black-and-white plumage.

Appearance

• Large, downward-curved yellow bill, proportionally very large relative to the head
• Blackish crown, back, and wings with white spotting on the wing coverts
• White underparts, throat, and face with a black facial stripe through the eye
• Short crest and relatively long tail
• Sexes similar, though females have a somewhat shorter bill

Key field marks

• Very large, bright yellow, downcurved bill
• Black-and-white plumage pattern with spotted wings
• Bounding, undulating flight typical of hornbills

Similar species

The Southern Red-billed Hornbill is smaller and slimmer with a thin bright red bill rather than a heavy yellow one. The African Grey Hornbill has an overall greyer, more subdued plumage and a dark bill with a pale casque ridge, lacking the bold yellow bill of this species.

Habitat

This hornbill favors dry savanna, thornveld, and open broadleaved woodland, often in areas with scattered acacia trees.

Range

It occurs across southern Africa, including Namibia, Botswana, Zimbabwe, and South Africa, extending into parts of Mozambique and Zambia.

Migration

It is non-migratory and sedentary, remaining within established territories or home ranges year-round.

Behavior

Southern Yellow-billed Hornbills are often seen in pairs or small family groups, foraging on the ground and hopping with an animated gait, flicking food items into the air before swallowing them. Flight is characteristically undulating, alternating flapping with glides.

Voice

Calls include a series of loud, piping "tok-tok-tok" notes that accelerate and rise in pitch, often delivered as a duet between paired birds with bobbing head movements.

Feeding

They feed opportunistically on the ground and in low vegetation, taking insects such as termites and beetles, small reptiles, seeds, and fruit, and are known to follow mammals or fires to catch flushed prey.

Nesting & breeding

Like other hornbills, females seal themselves into a tree cavity nest using mud, droppings, and food, leaving only a narrow slit through which the male passes food during incubation and early chick rearing; the female later breaks out once the chicks are partly grown.
