Fun Fact(s):
Very tame in areas around human habitation.
Like many related Tockus species, share interesting symbiotic relationship w/ Dwarf Mongoose. Hornbills act as “watchdogs” & protect mongooses from predators as well as giving them more time to feed. Both parties often engage in insect feasts.
“Zazu” of Lion King fame quite possibly based on this species.
Very interesting nesting habit-pair finds hollow tree cavity & build nest until only narrow opening left for male to bring food to mate, while female walled up during incubation & for 1 month after 1-6 chicks hatch. Female completely molts feathers & unable to fly during incubation period. After ordeal, female breaks free & both parents bring food to chicks for 2 more weeks until they emerge. Chicks stay w/ parents for 6-9 months. Male plays protector role.
