Rhyticeros is a genus of medium to large birds from the hornbill family.
Representatives of the genus Rhyticeros inhabit the rainforests of Southeast Asia and Oceania, from Burma and Thailand to the Solomon Islands. Sometimes birds of this genus are included in the hornbill of the genus Aceros. Rhyticeros have a large and powerful horny beak; as a rule, birds are decorated with a black plume of feathers, which on the head and back of the head can also be white or red-brown. The tail is white, except for the Rhyticeros everetti, which is black. The throat of Rhyticeros is covered with blue, easily inflated skin - except for the species Rhyticeros subruficollis and Rhyticeros undulatus, which have a yellow skin. The body of the birds is covered with black feathers.
The following species belong to the genus Rhyticeros:
- Reddish Calao Rhyticeros subruficollis
- Wavy kalao Rhyticeros undulatus
- Narcondam Hornbill Rhyticeros narcondami
- Sumbian Calao Rhyticeros everetti

The rhino bird (photos are presented in the article) is one of the most curious, in terms of appearance, representatives of the feathered world. The variety of sizes and colors does not interfere with recognizing individuals of this family by the following features:
- large and bright beaks,
- unusual growth on the beak,
- relatively short legs,
- the head is small,
- muscular long neck.
It is both secretive and quite noisy bird. Her flight is accompanied by sounds reminiscent of the movement of a train. They fly high and very well. They climb trees perfectly, because it is on them that they get their food. On the ground, they move heavily and awkwardly.
Sexual maturity occurs at approximately 3-4, in small species at 1-2 years. They are sedentary. Small representatives fly in small flocks of 20-40 individuals, large ones - in pairs.
The Indian hornbill is one of the largest members of the family. Growth reaches 1 meter in length, wingspan is 1.5 meters. The huge beak is decorated with a bright black and yellow outgrowth.
According to the international organization for the protection of birds and the preservation of their environment (BirdLife International), as of December 2020, there were 62 species in the world, united in 14 genera:
- Bucorvus is a horned raven. Large birds, weighing from 3 to 6 kg, throat and head without feathers, blue or red, sometimes two-colored. A distinctive feature is that it does not walled up a hollow.
- Rhinoplax - helmet-billed. Live weight up to 3 kg, have a high growth of red color. The naked neck is red in males, in females it is bluish-purple.
- Buceros are homrai. Weight 2-3 kg, have a very large, curved in front of the helmet.
- Ceratogymna is a helmet-bearing. Maximum weight 2 kg, stand out with large build-up. The sides of the head and throat are naked, blue in color.
- Rhyticeros. Large birds from 1.5 to 2.5 kg with high volume build-up.
- Aceros. Up to 2.5 kg, they have a poorly developed growth in the form of a small hump.
- Berenicornis are white-crested. They weigh up to 1.7 kg, there is a small horny outgrowth, in the female the cheeks and bottom of the body are black, in the male - white.
- Bycanistes are African. Live weight from 0.5 to 1.5 kg, with a pronounced large helmet.
- Anthracoceros are hornbills. Weight up to 1 kg, their helmet is smooth and large, with a bare throat.
- Ptilolaemus. Up to 900 grams, there is a small pronounced growth, the skin around the eyes is bare, blue in color.
- Anorrhinu are brown. Up to 900 grams in weight, stand out with a dark helmet, chin and areas around the eyes are naked, blue.
- Penelopides are Filipino. Small - up to 500 grams in weight, with a pronounced helmet, transverse folds are clearly visible on the beak.
- Tropicranus. Weigh within 500 grams.
- Tockus - currents. Small, weighing up to 400 grams, the helmet is small, in some species it is absent.
The tropical hornbill prefers woody landscapes. On the African continent, birds can be found from mountainous and equatorial wet forests to savannas and dry woodlands. Several species can coexist on the same territory. They coexist peacefully, occupying various ecological niches.
These birds are found in the southwest of the Arabian Peninsula, on the islands of the Indian and Pacific Oceans, in Southeast Asia. Hornbills are no longer found in Madagascar and Australia. Some species are endemic (live in a geographically limited area). Birds practically do not settle in places cultivated by people. They prefer virgin forests.
There is no clearly limited nesting period. Despite the diversity of species, most birds share a curious way of incubating their eggs. First, the male chooses a suitable nest. He himself cannot hollow it out, so he is looking for a suitable abandoned dwelling. Invites the female to the "bride", after the approval of the house, the birds mate.
Before the female lays eggs, the hollow is almost completely walled up with a mixture of earth, wood dust, fruit pulp, clay and droppings. All components are held together by saliva. There remains a small hole through which the male feeds first the female, and then the chicks. Sometimes lonely young males help him in this difficult task. Large birds have no more than three eggs. In smaller ones, it reaches 7.
The shelter protects future offspring from snakes, monkeys and other egg lovers. The incubation period lasts 6 to 8 weeks. During the incubation period, the female has time to completely change plumage. The male molts during the rainy season. In many species, couples are created for life. The hollow has been used for several years.
Hatching begins after the first egg appears, so chicks may have different ages. Constant control over the safety of the offspring leads to the fact that the wall is built and destroyed several times. First, the female flies out of the hollow after the end of the molt. Then the fledgling children, as they grow older, get out and learn to fly. After each exit of the next chick from the shelter, the wall collapses and is restored again, and so on until the last chick leaves the hollow. Chicks begin to learn to fly at the age of 3-4 months. They remain in the family until the next breeding season, and sometimes longer.
This behavior is not typical for all members of the species. Horned crows choose hollows mainly in baobab trees. They can settle in rock crevices. They do not brick up their "houses".
Varieties of hollow outgrowths of "horns" in rhino birds
Birds-rhinoceros got their name because of large long beaks, sharply curved downward and having significant outgrowths of various shapes at their base, which are absent only in representatives of the genus Toki (lat. Tockus). The edges of the beak are irregularly serrated. Despite their size, such beaks are very light, since inside them (as well as inside the bones of birds) there are large air spaces. However, in this case, there is an exception among the representatives of this family. The front part of the outgrowth of the helmet-billed kalao (Rhinoplax vigil) is dense, similar in structure to bone. Due to this, the mass of the skull in this species is about 11% of the total mass of an adult bird.The function of the outgrowths in hornbills is unclear, but scientists speculate that they may serve to support large beaks, amplify calls, or attract females.
The sizes of hornbills vary from 30 cm in the smallest representative, the small current (Latin Tockus camurus), to 1.2 m in the Kaffir horned crow (Bucorvus leadbeateri). Differences in weight from 60 g to 6 kg, respectively. Despite this range, hornbills are mostly large stocky birds. The accretion of the toes is characteristic: the second and third fingers grow together at half the length of the main phalanx, the third and fourth - by 2/3 of the phalanx. The exception is horned crows, whose toes do not fuse.
Hornbills have strong neck muscles to support their head and large beak. The head is small in relation to body size, the tail and neck are long, the wings are rather long, powerful, wide and strongly rounded, the legs are very short.
Kalao Valdena in flight
The flight of representatives of this family is rarely long, although despite this they are able to fly rather long distances. During flight, hornbills create a strong characteristic noise with their wings, similar to the sound of an approaching train. The reason for this is the air spaces between the flight feathers, which are not covered with small feathers like in other birds. During flight, air passes through the wings, resulting in a vibrating sound.
Unlike the beaks, which are quite colorful in many species of the family, the plumage of most hornbills is black, white, gray or brown. Feathers on the lower part of the body are hairy. Some species have bare patches of skin on the throat and around the eyes, and thick, long eyelashes on the upper eyelid. Males usually molt during the rainy season. In females of most species, tail and wing feathers are replaced during incubation of eggs and molt lasts long enough.
Males are on average larger than females: the difference in weight is on average 17%, in wingspan - 21%, beak length - up to 30%. In addition, in many species, sexual dimorphism is manifested in color. At the same time, in some species, such as the Mindanao wrinkled kalao (Latin Aceros leucocephalus), the differences between the male and the female are noticeable mainly in the color of the plumage, in others, like the black rhino bird (Anthracoceros malayanus), - only in the size and color of the beak.
Hornbills are quite noisy, in almost all species there is often a sharp dull monosyllabic or two-syllable cry, especially during the nesting period. It can be heard from time to time during the flight of birds, or when they are alarmed. If the bird is injured or caught, it emits a continuous, terrifying squeal. This sound can be heard even from a kilometer away.
Almost all species of hornbill are omnivorous. The habitat and the size of the beak dictate an addiction to different diets:
- Carnivorous. The birds feed on insects, small vertebrates, molluscs, amphibians, and small birds. These species include the Kaffir horned raven, and the Monteira current eats only insects.
- Vegetable. This diet is preferred by forest dwellers. The main food for them is the fruits of tropical trees. These include the black-helmeted and gold-helmed kalao
- Mixed. This type of food is typical for the Indian hornbill (pictured). In the crowns of trees, they find fruits, insects, and small animals. Their large size allows them to easily cope with small vertebrates.
Only a few species are able to drink water. Most of them get their needed amount of liquid from food.

Hornbills are considered as a family in the order Rakshaiformes. According to the Sibley-Alqvist classification, this family is separated into an independent detachment. Bucerotiformes
, in which two families are distinguished
where the horned crows belong, and
, which includes all other species of hornbill.
The classification of hornbills has changed quite often, therefore, in different literatures, certain types of birds are referred to different genera.
The hornbill family includes 14 genera and 57 species:
- Aceros Hodgson, 1844 - Asian kalao
Aceros cassidix (Temminck, 1823) - Sulawesian kalao
- Aceros corrugatus (Temminck, 1832)
- Aceros leucocephalus (Vieillot, 1816) - Wrinkled kalao
- Aceros nipalensis (Hodgson, 1829) - Nepali kalao
- Aceros waldeni (Sharpe, 1877)
- Anorrhinus austeni Jerdon, 1872
- Anthracoceros albirostris Shaw, 1808
- Berenicornis comatus Raffles, 1822 - Asian white-crested Kalao
- Buceros bicornis Linnaeus, 1758 - Two-horned kalao, or gomrai
- Bucorvus abyssinicus (Boddaert, 1783) - Abyssinian horned raven
- Bycanistes brevis Friedmann, 1929 - Silver-winged calao
- Ceratogymna albotibialis (Cabanis & Reichenow 1877)
- Ocyceros birostris (Scopoli, 1786) - Indian gray current

- Papuan kalao (Rhyticeros plicatus
- Tockus alboterminatus (Büttikofer, 1889) - Crowned current
- Tropicranus albocristatus (Cassin, 1848) - African white-crested calao
The threat of extinction
The hornbill is a forest dweller. For a full life, she needs spacious perennial forests. Several reasons put their existence at risk:
- the factor of disturbance by people in nesting places,
- hunting birds for eating, treating diseases, making souvenirs,
- ravaging nests: bird traders kill the female and take the chicks for sale.
The saddest situation is with three types:
- Anthracoceros montani (Suluan hornbill), it is known that the birds survived on the island of Tavi-Tavi. Their total number is only 40 individuals.
- Rhabdotorrhinus waldeni or red-headed hornbill. The population is no more than 4000 birds.
- Rhinoplax vigil (helmeted hornbill) - the number is steadily declining.
In addition, two species are critically endangered, five are vulnerable, and twelve are close to extinction.
Hornbills and humans
The beak of a two-horned kalao as a head ornament in the Nishi tribe.
These birds have been known to mankind for a very long time and are found in many ancient traditions and myths. Already in ancient Rome, these birds were known as "rhinoceros" birds. Their distinctively long beaks and great helmets are often used as ceremonial head adornments. So, the men of the Niche tribe wear hats bopa
with decorations from the beaks of a two-horned kalao. Originally worn only by chiefs and priests, today many men wear them as a symbol of fearlessness.
Malay Gomrai is the national symbol of the Malay state of Sarawak, which is reflected in its coat of arms, which depicts this bird with outstretched wings. For the local population, this bird is a symbol of purity and purity. People often use either the bird itself or its image in religious rituals. The Malay Gomrai with his helmet lifted up symbolizes one of the most powerful Dayak gods - the god of war Singalang Burong (Malay.Singalang Burong), which plays an important role in the Iban religious festivals, especially the "hornbill festival" (Gawai kenyalang
). This state is home to many species of hornbill, which is why it is often referred to as the "country of hornbill". In Sarawak, as in other countries of Southeast Asia, hornbills are protected species.
The Indian state of Nagaland also hosts the "Hornbill Festival" every year. The two-horned kalao or large Indian rhinoceros is a universally revered bird in this state. In another Indian state - Arunachal Pradesh - this bird is a symbol of the state and is displayed on its emblem. The Sulawesian kalao (Latin Aceros cassidix) is the symbol of the Indonesian province of South Sulawesi.
Many hornbills are large forest birds and require large forest areas with many old trees to nest. Due to intensive deforestation, the future of these birds is threatened. People hunt birds, using them as food, remedies for diseases, and for making souvenirs: inlaid skulls and beaks. The dense outgrowths of the helmet-billed kalao (lat. Rhinoplax vigil) are used as a material for the manufacture of netsuke.
Two species of hornbills are Endangered, and two more are Critically Endangered. Five species are classified as Vulnerable, and another 12 species are Near Threatened.
Hornbills can be seen on the flag of the Burmese state of Chin, on stamps in many countries in Africa and Asia. On 25 Zambian ngwees, the crowned current (Latin Tockus alboterminatus) is depicted. In the animated film The Lion King, the red-billed current (Tockus erythrorhynchus) serves as the model for Zazu the rhino bird.
