Similar species
Northern Yellow-billed Hornbill (Tockus flavirostris), which is found further north in East Africa and has a brighter yellow bill and more extensive spotting, and Von der Decken's Hornbill.
Ecological significance
Acts as an important seed disperser in its native woodland and savanna habitats, and plays a role in controlling insect populations.
Conservation status
Least Concern, with stable populations across its wide range.
Observation tips
Look for them in open dry savanna and woodland areas, often foraging on the ground or perched prominently on low branches. They are relatively bold and frequently approach campsites or picnic areas in search of food.
Interesting facts
This species inspired the character Zazu in Disney's 'The Lion King'. They often forage in loose groups or pairs and have a cooperative relationship with dwarf mongooses, joining them to catch flushed insects.
