Von der Decken hornbills are native to dry regions of eastern Africa. Males have large, red bills while females have black bills. Like other hornbills, female Von der Decken hornbills bury themselves alive to hatch and rear their chicks. For two months, the male feeds the female and the chicks through a slit in the mud nest.
Food/Eating Habits In the wild they eat small ground prey, eggs, fruits and insects
