Tickell's brown hornbill (Anorrhinus tickelli), also known as the rusty-cheeked hornbill, is a species of hornbill found in forests in Burma and adjacent western Thailand. Austen's brown hornbill is sometimes considered as a subspecies of Tickell's brown hornbill.
At about 60–65 cm (24–26 in) in length, it is a medium-sized hornbill, dark brown above and red-brown below. The male has brighter rufous cheeks and throat. Juveniles of both sexes resemble adult males.
It inhabits evergreen and deciduous hill forest from foothills to 1500 m.
It breeds co-cooperatively, in groups.
Habitat loss to logging and agriculture is known to be prevalent within its range.
The binomial commemorates the ornithologist Samuel Tickell.
Hornbills are birds found in tropical and subtropical Africa, Asia and Melanesia of the family Bucerotidae. They are characterized by a long, down-curved bill which is frequently brightly coloured and sometimes has a horny casque on the upper mandible. Hornbills have a two-lobed kidney. They are the only birds in which the first and second neck vertebrae are fused together; this probably provides a more stable platform for carrying the bill. The family is omnivorous, feeding on fruit and small animals. They are monogamous breeders nesting in natural cavities in trees and sometimes cliffs. A number of mainly insular species of hornbill with small ranges are threatened with extinction, namely in Southeast Asia.
Colonel Samuel Richard Tickell was an English soldier, artist, linguist and ornithologist in India and Burma.
The wrinkled hornbill or Sunda wrinkled hornbill is a medium-large hornbill which is found in forest in the Thai-Malay Peninsula, Sumatra and Borneo.
The silvery-cheeked hornbill is a large species of hornbill found in Africa. Silvery-cheeked hornbills are residents of the tall evergreen forests of East Africa from Ethiopia to South Africa. In Zimbabwe it is threatened by habitat destruction and its presence in South Africa is marginal, but it remains locally fairly common, especially in the northern and central parts of its range.
The trumpeter hornbill is a medium-sized hornbill, with length between 58 and 65 cm, characterized by a large grey casque on the bill, smaller in females. The eyes are brown or red, with pink surrounding skin. Body mass is between 0.45 and 1 kg. It is similar to silvery-cheeked hornbill. Distinguishing features include an all-black back, white belly and white underwing coverts, and red facial skin.
The great hornbill, also known as the concave-casqued hornbill, great Indian hornbill or great pied hornbill, is one of the larger members of the hornbill family. It occurs in the Indian subcontinent and Southeast Asia. It is predominantly frugivorous, but also preys on small mammals, reptiles and birds. It has been listed as Vulnerable on the IUCN Red List since 2018. It is known to have lived for nearly 50 years in captivity. Due to its large size and colour, it is important in many tribal cultures and rituals. The Government of Kerala declared it as the official Kerala state bird.
Austen's brown hornbill is a species of hornbill found in forests from northeastern India and south to Vietnam and northern Thailand. It is sometimes included as a subspecies of Tickell's brown hornbill.
Blyth's hornbill, also known as the Papuan hornbill, is a large hornbill inhabiting the forest canopy in Wallacea and Melanesia. Its local name in Tok Pisin is kokomo.
Bucerotiformes is an order of birds that contains the hornbills, ground hornbills, hoopoes and wood hoopoes. These birds were previously classified as members of Coraciiformes. The clade is distributed in Africa, Asia, Europe and Melanesia.
Sumba hornbill, or known natively as Julang is a large bird belonging to the family of Bucerotidae, endemic and native to the Indonesian island of Sumba. The scientific name commemorates British colonial administrator and zoological collector Alfred Hart Everett.
The black-and-white-casqued hornbill also known as the grey-cheeked hornbill, is a large black and white hornbill. It has an oversized blackish bill with a large casque on top. The female is slightly smaller than the male and has a significantly smaller casque. It is a monogamous species, and pairs nest in suitable tree cavities. The female usually lays up to two eggs. The diet consists mainly of figs, fruits, insects and small animals found in the trees.
The knobbed hornbill, also known as Sulawesi wrinkled hornbill, is a colourful hornbill native to Indonesia. The species is sometimes placed in the genus Aceros. The knobbed hornbill is the faunal symbol of South Sulawesi province.
Tickell's bat is a species of vesper bat. It can be found in Bangladesh Bhutan, Cambodia, possibly China, India, Myanmar, Nepal, Sri Lanka and Thailand.
The bushy-crested hornbill is a bird in the hornbill family. It is found in Brunei, Indonesia, Malaysia, Myanmar, and Thailand. Its natural habitat is subtropical or tropical moist lowland forests.
The Sulu hornbill, or Montano's hornbill, is a species of hornbill in the family Bucerotidae. It is endemic to the Sulu archipelago in the Philippines, with the remaining populations in Tawi-Tawi with it believed to be hunted to extinction on Jolo. Its natural habitat is tropical moist forests. It is threatened by habitat loss as well as potential harvesting for food. Its diet includes fruit, insects, and small lizards.
The brown-cheeked hornbill is a species of hornbill in the family Bucerotidae. It is found in Ivory Coast, Ghana, Guinea, Liberia, Sierra Leone, and Togo. Its natural habitats are tropical and subtropical moist broadleaf forests, plantations, and secondary growth forests. It is threatened by habitat destruction, as timber is harvested and the forests become increasingly fragmented.
The Mindoro hornbill is a species of hornbill in the family Bucerotidae. It is endemic to forests on Mindoro in the Philippines found in tropical moist lowland forests. As is the case with all Philippine tarictic hornbills, it was once considered a subspecies of P. panini. It is the only tarictic hornbill where both sexes are creamy-white and black. The sexes are very similar, differing primarily in the colour of the ocular ring. It is threatened by habitat loss, and is consequently considered endangered by the IUCN.
The brown hornbill has been split into two species:
Dong Ampham National Biodiversity Conservation Area is an extensive protected area which covers a significant part of Attapeu Province and Sekong Province in the southeast corner of Laos on the border with Vietnam. It covers the northeastern part of Attapeu Province and southeastern part of Sekong Province.
