Oriental pied hornbill taxonomy

The Bucerotidae is the family of hornbills. The family Bucerotidae was first introduced by Constantine Samuel Rafinesque-Schmaltz (October 22, 1783 – September 18, 1840), a zoologist and botanist, in the year 1815.

The family Bucerotidae comprises, subfamilies Bucorvinae (ground hornbills) and Bucerotinae (typical hornbills). The subfamily Bucerotinae comprises fifteen genera, including Anthracoceros.

The genus Anthracoceros was first described by Heinrich Gottlieb Ludwig Reichenbach (January 8, 1793 – March 17, 1879), a German botanist and ornithologist, in the year 1849.

The genus Anthracoceros comprises five species, viz., Anthracoceros albirostris, Anthracoceros malayanus, Anthracoceros coronatus, Anthracoceros marchei and Anthracoceros montani.

The species Anthracoceros albirostris is polytypic. It was first described by George Kearsley Shaw (10 December 1751 – 22 July 1813) and Frederick Polydore Nodder in the year 1807.

The Narcondam hornbill (Rhyticeros narcondami) is closely related to Blyth's hornbill (Rhyticeros plicatus) and wreathed hornbill (Rhyticeros undulatus).

Appearance, physical description and identification

The Narcondam hornbill (Rhyticeros narcondami) is a small hornbill, measuring 45 to 50 cm in length.

The Narcondam hornbill are sexual dimorphic, both in size and plumage. The male is slightly larger and weighs 700 to 750 grams. The female bird weighs 600 to 750 grams. The overall plumage is blackish. These species appear like a miniature version of Blyth's hornbill (Rhyticeros plicatus).

The male hornbill upperparts are black with green gloss. The male has rufous head, neck and upper breast. The rest of the underparts are black. The male has orange red irises. The female is totally black. In female, the irises are olive brown.

There is a pale blue gular pouch and short white tail in both the sexes. The bare skin around the eyes is bluish. The juveniles look similar to males and have dull-looking bills without folds.

The base of the bill is pinkish. The upper mandible has folds near the base. The furrows of the casque are brownish. The legs are blackish and the soles are yellow. Their call is a loud, harsh cackling “ka-ka-ka-ka” sound.

Origin, geographical range and distribution

These hornbill species are distributed in Narcondam, a small dormant volcanic island in the Andaman Sea, forming part of Andaman Islands. It covers 6.8 sq. kilometers. The Important Bird and Biodiversity Area (IBA) of these hornbill species in India is the Narcondam Island Wildlife Sanctuary.

Ecosystem and habitat

These Narcondam hornbill species are highly forest dependent. These species occur in altitudes from 0 to 700 meters.

The natural ecosystems of these species include tropical and subtropical moist lowland forests, open mixed forests and tropical and subtropical moist shrublands.

Diet and feeding behavior

The diet of these Narcondam hornbill species is mostly fruits. Wild fruits, berries, figs, invertebrates and small reptiles are their primary food.

Reproduction and breeding habits

The breeding season of these Narcondam hornbill species is from February to April. The nesting sites are located in mature, undisturbed forests with large trees.

These hornbill species nest in holes and hollows in trunks and broken branches in large trees. The favored nesting trees are, bully trees (Sideroxylon spp.) and tropical chestnuts (Sterculia spp.).

These birds are monogamous. The female hornbill seals herself in the tree hollow with faeces and fruit pulp. A small slit is left open for male to pass on the feed for the female and later the chicks.

During this time, the female sheds her flight feathers and is incapable of flight. The typical clutch contains two eggs. Though these birds have been maintained in captivity, so far, there has been no success in captive breeding.

Migration and movement patterns

The Narcondam hornbill species are non-migratory resident birds.

Post breeding, the hornbill juveniles may disperse and establish in new locations within the range. They may make local movements for feeding and breeding within their range.

Conservation and survival

The global population size of the Narcondam hornbill (Rhyticeros narcondami) is estimated to be around 50 to 250 individual birds. The overall population trend of these hornbill species is considered to be stable. Throughout its range it is reported to be common. The generation length is 19 years. Its distribution size is about 7 sq.km.

The Narcondam hornbill (Rhyticeros narcondami) has approach the thresholds for being Endangered, under the range size criterion, under the population trend criterion and also under the population size criterion. The ongoing habitat destruction, persecution by introduced cats and hunting are the main threats that may endanger the survival of these hornbill species.

IUCN and CITES status

The IUCN (International Union for Conservation of Nature) has categorized and evaluated the species and has listed it as "Endangered". The CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) status is ‘Evaluated’ for the Narcondam hornbill (Rhyticeros narcondami) and is listed in Appendix II.

Taxonomic classification   <>   Photos
The wreathed hornbill (Rhyticeros undulatus) belongs to the family Bucerotidae under the order Bucerotiformes.

Conservation concerns of Rhyticeros undulatus

The survival of Rhyticeros undulatus is "threatened by illegal selective logging, habitat encroachment and local hunting pressure in unprotected tropical forestlands".

Logging has fragmented the habitat and created huge gaps in the vegetation thus these birds are easily sighted, making them more vulnerable to hunting.

Logging, agricultural expansion into forest areas and illegal logging of mature trees has lead to sharp decrease in the roosting sites and foraging sites (Ficus sp.) of wreathed hornbill. There is decline in the regeneration of the preferred tree species (Ficus sp.).

The Rhyticeros undulatus species are important agents of seed dispersal in the moist evergreen forest. The entire ecosystem of these species is at cross roads. These birds require mature trees for nesting and also require foraging trees. The fragmented forest can only be effectively regenerated by these seed dispersers.

Origin, geographical range and distribution

The wreathed hornbill species are distributed in India, Bhutan, Bangladesh, Myanmar, Thailand, Laos, Vietnam, Cambodia, Malaysia, Indonesia and Brunei.

In India, these hornbill species are distributed in the states of Assam, Arunachal Pradesh, Meghalaya, Nagaland, Manipur, Tripura and Mizoram.

Ecosystem and habitat

These wreathed hornbill species have high forest dependence. These species occur in altitudes from 0 to 2560 meters.

The natural ecosystems of these wreathed hornbill species include tropical and subtropical moist lowland forests, primary evergreen forests and tropical and subtropical moist montane forests.

Diet and feeding behavior

The diet of these wreathed hornbill species is mostly fruits. Wild fruits, berries, figs and small animals are their primary food.

Reproduction and breeding habits

The breeding season of these wreathed hornbill species in India is from April to June. The breeding season is from January to March in Myanmar and Thailand. The laying season in Indonesia is from March to September.

These wreathed hornbill species are monogamous and are highly territorial. They nest in tree holes. They prefer the deciduous tree species Tetrameles nudiflora, which have large hollows in the trunk and branches. The same nesting site may be used in consecutive breeding seasons.

The nesting sites disturbed by human activities may be abandoned. Loss of nesting habitat and nesting trees has a direct effect on the breeding success of these wreathed hornbill species.

The breeding female enters the hollow and seals the hole with its droppings, mud and fruit pulp. A small aperture is left for the male to transfer food to the mother and the chicks. The typical clutch contains two or three pale white eggs.

Migration and movement patterns

The wreathed hornbill species are non-migrant resident birds. Post breeding, the wreathed hornbill juveniles may disperse and establish in new locations within the range. They may make local movements for feeding and breeding within their range.
