Share interesting symbiotic relationship w/ Dwarf Mongoose. Hornbills act as “watchdogs” & protect mongooses from predators & give mongooses more time to feed. Both parties often engage in insect feasts.

Named after German explorer Baron Karl von der Decken.

“Zazu” of Lion King fame quite possibly based on this species.

Have 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 2-3 months after 1-3 chicks hatch. She completely molts her feathers & is unable to fly during incubation period. After this ordeal, female breaks herself free & both parents bring food to chicks for 2 more weeks, until they emerge. Chicks stay w/ parents for 1 year. Male plays protector role.
