Rhinoceros hornbills are non-migratory diurnal birds. Helson Hassan, one of my guides and a hornbill conservationist, pointed to a huge meranti tree. Ravinder, who is 38, once disliked conservation biology. The Rhinoceros hornbill is a giant, forest-dwelling species of south-eastern Asia. Before the pandemic, thousands of tourists, mostly European, filled the riverboats that regularly cruise through the sanctuary, hoping to catch a glimpse of its wild residents. The chicks leave the nest when they are 80 days old but the parents continue to feed them for another 6 months. Native to Malaysia, Sumatra, Borne, and Thailand, the rhinoceros hornbill makes its home in lowland forests that have trees capable of hosting nests. Ravinder helped expand the organization’s work to hornbills, and she launched a separate group, called Gaia, dedicated to hornbill conservation. She found that the temperature and humidity within the nest boxes, which were made of plastic and encased in Styrofoam and cement, were more than twice as variable as those within the natural cavities. While nest boxes and cavity repairs can help hornbills, they are imperfect, short-term solutions. If you were to mistake the rhinoceros hornbill (Buceros rhinoceros) for some sort of prehistoric dinosaur, you wouldn't be alone.This big, mostly black bird has more in common with dinosaurs than just feathers and fierce, staring eyes. As they typically do in tree cavities, the females sealed themselves and their eggs inside the boxes, narrowing the entrances with soil and feces. Rhinoceros hornbills' casque is made of keratin and is hollow inside. This casque acts as a resonating chamber to amplify the birds calls. Early nineteenth century drawing of the Rhinoceros hornbill (Buceros rhinoceros), … After the 2016 hornbill breeding season, the empty boxes looked like “epic failures,” Ravinder said. The eyes of the male are red with black rims, and white with red rims in the female. I stared up at the tree trunk, whose cavity had housed at least five helmeted hornbill fledglings in the past. But when she took a class trip to the rain forests of Danum Valley in Sabah, she experienced the joys of studying wildlife: sleeping under starry skies and giant trees, following elephant trails, and listening to orangutans swing through the canopy. Now check out the different hornbills on these pages. The rhinoceros hornbill is a large arboreal hornbill, 80 to 90 cm (31–35 in) long. Rhinoceros hornbills are almost as picky about their nest sites as their helmeted cousins, and the chick was the world’s first rhinoceros hornbill to fledge from an artificial nest box outside of captivity. Three birds were perched on a leafless branch: two oriental pied hornbills, and one adult male helmeted hornbill. After 2013, Yoki asked villagers in Sumatra and Borneo if they had seen the bird or heard its distinctive laughter-like call. The eyes of the male are red with black rims, and white with red rims in the female. It is believed that it acts as a resonating chamber and helps birds to sound loudly across a large distance. The casque of the rhinoceros hornbill has a relatively low weight because of its spongy composition. “The whole family was threatened now, so close to the ground” and vulnerable to predators, Ravinder recalled. “There is no one single magic number,” says Chin-Aik Yeap, senior conservation officer at the Malaysian Nature Society and a member of the IUCN Helmeted Hornbill Working Group. The plumage is predominately black, with white legs and vent and a white tail with a black band. Rhinoceros Hornbill is a type of bird Friend. HUTAN, which means “forest” in Malay, was founded by primatologists, and its researchers have been studying orangutans in the Kinabatangan sanctuary since the late 1990s; they began studying elephants in 2000. The sanctuary’s animals seemed to be enjoying the lull. The female had emerged from the cavity five weeks before, but had gone missing. The bill also comes with additional decoration: a casque (KASK). Read: The birdsong that took over North America. Appearance. As the parents flew down to their fledgling, which was perched unsteadily with its feet wide apart, Ravinder and Sanjitpaal watched in horrified suspense. We stepped into muddy puddles—made by wild boars the night before—and squeezed between rocks, taking care to avoid the gaping holes that plunged into dark underground limestone caves. Habitat destruction has led to the loss of the large trees the birds require for breeding, which in turn makes it easier for poachers to find Rhinoceros hornbills. The hornbills of Southeast Asia face multiple threats to their survival. They even attached ferns to one cavity for shade. Hornbill Scientific Name. It is believed that it acts as a resonating chamber and helps birds to sound loudly across a large distance. Logging and development have decimated the forests they live in: Between 1990 and 2010, the region lost 79 million acres of forest, an area around the size of New Mexico. In 2017, as part of her doctoral research, Ravinder and her team surveyed the tree cavities within a 2,500-acre section of the sanctuary. They have black feathers on their wings and body and their tail feathers are white. Most of the older hardwood trees have been cut down, and with them many of the larger, higher tree cavities that form when heart-rot fungi attack the center of a tree trunk. The river, swollen by the unseasonably heavy rains, flowed swiftly and quietly. Poachers sometimes mistake rhinoceros hornbills for helmeted hornbills. “We are still scratching our heads,” she said. This article is part of our Life Up Close project, which is supported by the HHMI Department of Science Education. The large bill and casque are yellow and orange-red (black at the base in males); bill is slightly recurved with upturned casque … Their huge bill and casque are orange and red. I’d been lucky, but so far not lucky enough to see a helmeted hornbill glide through the forest with its massive wings extended like a living dinosaur’s. Helson patted my back. Ravinder looked toward the sound and saw a stout man walking up a nearby rocky hill, carrying a long bamboo pole. While some smaller hornbill species can survive in semi-urban or fragmented forests, helmeted hornbills and other large species need vast, contiguous forests with tall, thick-trunked nesting trees. The Rhinoceros Hornbill has a prominent golden-yellow horn, called a casque, on the top of its beak. The hornbill ranges in size between 19 inches and 63 inches. They also knew that they couldn’t wait for the sanctuary’s trees to grow larger, and for heart-rot fungi to slowly invade their trunks. “We were ready to take them down.”. While the helmeted hornbill population in the sanctuary was better protected than most, Ravinder and her colleagues knew that it needed more nesting cavities to survive. They live and spend time in pairs, however, sometimes they may gather in small flock while feeding. It produces a series of short, resonant “rroh” calls, often given by both mates on two different pitches, while perched or in flight. Yoki’s findings shocked the conservation community, and in 2015 the helmeted hornbill was designated as “critically endangered,” just one rung away from “extinct in the wild” on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. Yoki had long suspected that the species was in serious danger, but no one had documented the extent of the poaching—or even the number of surviving helmeted hornbills. Rhinoceros hornbills have one of the largest and most impressive casques. The same year, the Indonesian government approved a conservation plan for helmeted hornbills; Thailand is now developing its own national plan. Ravinder and Helson speculate that the birds might be avoiding the lingering smell of epoxy, or might be put off by the lack of moss and lichen on the walls. Capable of living more than 30 years, the bird is noted for its prominent casque, a unique helmet-like structure that grows on its beak. But the park’s helmeted hornbills have shown no interest in the boxes. These beautiful birds are also frequently shot at by poachers due to confusion with the highly sought-after Helmeted hornbill. But HUTAN was busy with the demands of conserving elephants and orangutans and did not monitor the hornbill boxes. Rhinoceros hornbills have one of the largest and most impressive casques. “I liked dogs and cats, not wildlife,” she told me. The chick was still in the nest, fed by the male alone. While the progress is thrilling, Ravinder’s team can’t tell why those particular nest boxes appealed to the birds. Rhinoceros hornbill casques (the large, hardened structure on top of the beak) and tail feathers are used in traditional medicines and for ceremonial purposes. They scrambled back to the river and later lodged a police report. The Rhinoceros hornbill is the state bird of the Malaysian state of Sarawak and the country's National Bird. On most hornbills, the casques are hollow and lightweight. The most distinctive feature of the Rhinoceros Hornbill Buceros rhinoceros (Vulnerable) is its spectacular horn or “casque”. After graduation, she was hired by the Malaysian Nature Society, where she worked to conserve endemic butterflies and plants. Helson’s team, led by the researcher Ravinder Kaur, studies hornbills and their nesting activities in the Kinabatangan sanctuary. As you can see, their casques come in all shapes, sizes, and colors, depending on the species. In 2019, near the end of the rhinoceros hornbill breeding season, Ravinder and her husband, Sanjitpaal Singh, a professional photographer, waited on a boat on the river in hopes of seeing a fledgling emerge from one of the boxes. This feature comes from hadrosaurids from more than 60 million years ago. Hornbills enjoy sunbathing and often perch with spread wings facing the sun. Nesting Behavior. But the species is immediately recognizable by its maroon-colored “helmet,” or casque—a brick-shaped growth of keratin at the base of its beak that covers its brow and the crest of its head. She has short black hair and a large red yellow and white beak with casque on her head. It's thought to act as a resonating chamber and to be significant in communication, especially during the mating process. The main threats to Rhinoceros hornbills include loss of their rainforest habitat, as well as hunting for their meat, skull, and feathers. Hornbill Valley, Taman Negara, Pahang – If you prefer to stay away from tourist destinations, the Hornbill Valley is a suitable, quiet location for Hornbill watching as it is only frequented by local birdwatchers. But the man saw them; he turned around and waved a warning at someone behind him. The nest boxes had failed to replicate the stable and cool environments of the natural cavities, and while a few hornbill species visited them, only a single pair of oriental pied hornbills stayed to build a nest. All of the cavities remained unoccupied during the hornbill breeding season. Then they heard a gunshot, possibly two. This feature atop the birds head is not surprisingly the influence behind their common name. The phase-two design kept temperature and humidity fluctuations inside the box to a narrow band, maintaining conditions close to those of the natural cavities. Conservation Series. “I like to keep positive and think that maybe in a couple of years’ time we’ll see them coming back, and we find out that maybe this is just a pattern that happens,” Ravinder said. To date, five rhinoceros hornbill chicks have fledged from the nest boxes. My guides led me along a narrow trail uphill through the forest. Encounters with crocodiles, elephants, and wasps are occasional but inevitable hazards. The Rhinoceros Hornbill, Buceros rhinoceros, is one of the largest hornbills, adults being approximately the size of a swan, 91–122 cm (36–48 in) long and weighing 2–3 kg (4.4–6.6 lbs). For the past two months, Helson had been watching the hole closely, hoping that it would once again house a family of helmeted hornbills. Buceros rhinoceros silvestris: Java in Indonesia (from East Java to Meru Betiri), with a long casque and wider black tail band. Could it be? Since then, nobody on the Gaia team had seen the helmeted hornbill pair or their fledgling, and during our visit in July, Helson wasn’t optimistic; after 20 minutes of watching, he seemed ready to leave. At the age of 6 years, the casque and bill become orange and red; this color comes from preen oil which birds rub on from the preen gland above the tail during grooming to help keep their feathers healthy. The huge bill and casque are orange and red, the colour coming from preen oil rubbed on from the preen gland above the tail. During the past two days, I’d seen 15 elephants feeding and bathing by the river; three orangutans—one pregnant and one with a baby—sitting in a fig tree; scores of proboscis monkeys, showing their bulbous noses and red erect penises; and flocks of black hornbills, wrinkled hornbills, and bushy-crested hornbills. Rhinoceros hornbills are found in lowland and mountain rain forests in Borneo, Sumatra, Java, the Malay Peninsula, and southern Thailand. “Even though they spend one week in the forest, [they] would be very damn lucky to hear just one,” he told me. During his daily rounds, Helson might scan the skies from a boat on the river; follow hornbill males as they carry figs and insects back to their nests; and check the ground for hornbill feces, a sign of birds nesting above. The rhinoceros hornbill is the national bird of Malaysia. Suddenly, a twig snapped. The team sensed that things were amiss; though the sanctuary is closed to unauthorized visitors, they had recently smelled cigarette smoke along the trail in the early morning. Everything was wet from days of afternoon thunderstorms and late-night drizzles. In Budo–Su-ngai Padi National Park in southern Thailand, the Hornbill Research Foundation has installed 22 boxes, and over the past 16 years, 55 hornbill chicks have fledged from them. Back on the hill in the Kinabatangan sanctuary, Helson and I waited for signs of a helmeted hornbill. The casque is a hollow structure made up of keratin (the same material as human fingernails) and acts as a resonating chamber, amplifying the bird’s calls. Hours later, police arrived and searched the forest, but no intruders were found. While land animals like tigers can be surveyed with camera traps, surveying birds requires a lot of hiking through forests to see or hear them, Yeap told me, and given the remote, thickly forested terrain preferred by helmeted hornbills, “obtaining even the most basic of estimates from the field is—to put it in a simple word—hell.”. During this period the female undergoes a complete molt. HUTAN collaborated with European zoos to build and install five nest boxes in the forest. Yet the Kinabatangan sanctuary is not the thick rain forest one might expect. The primary diet of these birds consists of fruit, especially figs but they will also consume insects, small reptiles, rodents, and smaller birds. Description: A young hornbill with its casque/horn still not fully developed yet. “Wait for it.”, “Hoo … hoo … hoo-hoo …” The calls quickened, the notes smashing together before bursting into a rapid “Ha-ha-ha-ha-ha-ha!”.

The Rhinoceros hornbill is featured on the reverse of the 5 Malaysian ringgit bill. In 1975, the international trade in helmeted hornbills was outlawed under the Convention on International Trade in Endangered Species of Wild Fauna and Flora, but sales continued on the black market. In some places, artificial nest boxes have successfully boosted hornbill numbers. The Kinabatangan Wildlife Sanctuary, which straddles the floodplain of the 350-mile-long Kinabatangan River, is home to a wide array of wildlife: Bornean pygmy elephants, orangutans, crocodiles, and eight species of Asian hornbills, six of which are threatened. Named the Rhinoceros Hornbill for it's large "horn" that points upwards like a … The males, left to forage, fed their families through a slit in the clay barrier. “Good job, bro.

The rhinoceros hornbill and the great hornbill have very similar nesting behaviors, though they … “Hoo … hoo … hoo …” A series of solid, rounded calls rang in the distance. She applied to study veterinary science at university, but was instead offered a place in a conservation-biology program—her last choice. During her first year, upset about losing her dream career, Ravinder sat at the back of the class and was so miserable she lost weight. Contrary to some misunderstandings, the Rhinoceros hornbill does not represent their war god, who is represented in this world by the Brahminy kite. And without cavities, the Kinabatangan sanctuary can’t provide much sanctuary to hornbills. The helmeted hornbill can’t procreate without a particular type of tree hole, so scientists are trying to build it artificial ones. The air smelled green and fresh, but with an underlying note of decay. 2. The next moment, the fledgling was out of the box—and then falling, landing on a shrub near the water.

One wrong move by the fledgling and it might drown in the river. In a four-year study of forest plots in Argentina, Cockle found 17 bird cavity nests in unlogged forests but only one in logged forests. In late 2012, an Indonesian hornbill conservationist named Yoki Hadiprakarsa received a photo, from a friend, showing stacks of helmeted hornbill heads for sale at an Indonesian village market. Improving an existing cavity is cheaper and faster than installing a nest box—as long as you have basic carpentry skills and the courage to climb into the tree canopy. As much as Ravinder would like to continue improving and introducing nest boxes, each one costs hundreds of dollars and requires hundreds of hours to make and install. Some species have seemingly enormous casques, as is the case of the rhinoceros hornbill (Buceros rhinoceros) of Malaysia and Indonesia, and the black-casqued hornbill (Ceratogymna atrata) of West Africa. Rhinoceros Hornbill. While the number of hornbill products available online appears to be declining, experts say, enforcement might have simply driven poachers and traders deeper underground.

They had no idea how many people there were, or what they wanted. In 2018, the IUCN Species Survival Commission’s Hornbill Specialist Group announced a 10-year conservation action plan for helmeted hornbills, outlining actions needed to protect hornbill habitat and eliminate illegal trade. Un-logged forests with enough tree cavities would not even require nest boxes, the researchers Yeap and Yoki told me. Ravinder Kaur and her team in the Kinabatangan Wildlife Sanctuary were—and still are—among a tiny handful of researchers paying close and sustained attention to helmeted hornbills. Helson vividly remembers a day in November 2019 when he, Ravinder, and Sanjitpaal were observing the nest. Suddenly, he pointed into the forest and motioned for me to listen. You didn’t see a helmeted hornbill, but good enough to hear it,” he said. “Whatever happened to them, we felt it too.”. Rhinoceros hornbills are mistaken by poachers for critically endangered helmeted hornbills, which have casques made of solid keratin that Lindholm said are more valued than ivory. (While her findings suggest that few cavity-nesting birds are able to breed in logged forests, further studies are needed to determine if the birds’ breeding was limited by cavities or some other factor.). NGOs in Indonesia are also hiring local residents as rangers, training them to watch for and report hornbill poachers in their forests. The Rhinoceros hornbill is the state bird of the Malaysian state of Sarawak and the country's National Bird.
