In groups, couples stay together only during the breeding season, when both sexes are fiercely territorial and powerful calls sound like advocacy to prove their presence. Feeding on ripe fruit, insects, small lizards, and even small birds, hornbills often follow groups of monkeys in order to find ripe fruit, and animal ingredients make up about 30 percent of their food source.

The Malaysian hornbill attaches great importance to showing love, and the male must be trusted by the female before mating, laying, brooding and raising chicks. Nesting and spawning season from January to April, choose a tall trunk about 16 to 33 meters away from the ground in the tree hole for the nest, they do not peck wood, are the use of natural decay or termite invasion and bite of the cave. The breeding habit of hornbills is very special, the female bird chooses the nest site, lays a layer of wood chips at the bottom of the hole, and lays 1 to 2 pure white eggs in the hole. After laying eggs, squatting in the nest no longer goes out, and piles his excreta mixed with seeds and rotten wood in the hole. Male birds from outside the nest frequently bring wet mud, fruit residue, to help female birds seal the hole. The material that seals the tree hole seeps through the viscous stomach juices of the female bird, so it is very strong. Finally, a vertical gap is left in the hole for the female to reach out to the male for feeding. The female stays in the hole for months, only to escape when the chicks are ready to fly. Incubation lasts 37 to 42 days. They remain in the shelter for up to three months after the chicks hatch. In the meantime, the males feed. Male birds can peel off the innermost layer of the stomach wall and spit it out in a thin film, which is used to store fruit for female birds and young birds to eat. The female bird comes out of the hole with new feathers and is immediately responsible for feeding her chicks. Female birds in the closed cave, but also from time to time to clean feces and other dirt, it directly throws out the hole with its mouth, when it defecates itself, the anus directly sprayed out of the hole, this strange way of life, may be the harm of natural enemies, and with the harsh natural environment to fight against the formation of adaptation.
