Yellow-billed Hornbills (Southern & Eastern) are iconic African savanna birds known for their long yellow bills, ground foraging (insects, seeds, small animals), and unique nesting where the female seals herself in a tree cavity, relying on the male for food through a small slit. They form pairs, call loudly, hop on the ground, and even have symbiotic hunting with dwarf mongooses. They're common in dry thornfields and woodlands, known for their distinctive calls and curious nature.

Diet: Omnivorous; insects (termites, ants, grasshoppers), spiders, scorpions, small vertebrates, seeds, fruit.
Foraging: Primarily on the ground, but also low in bushes, often following dwarf mongooses.
Nesting: Cavity nester; female seals herself in with mud/dung, leaving a slit for male to feed her and chicks; she molts flight feathers inside.
Calls: Loud, rolling "ko-ko-ko" or "woh-woh-woh" calls, often increasing in volume.
Behavior: Form pairs, territorial, active during day, tame around humans, cooperative hunters with mongooses.
Species: Primarily the Southern Yellow-billed Hornbill (Tockus leucomelas).
Interesting Habits:
Symbiosis: Hunt with Dwarf Mongooses, benefiting each other.
"Flying Banana": Nicknamed this due to their shape and bill color.
Moulting: Female sheds feathers while sealed in the nest.
