The Mindanao hornbill (Penelopides affinis), also known as the Mindanao tarictic hornbill, is a medium-small species of hornbill found in the canopy of rainforests on Mindanao, Dinagat, Siargao and Basilan in the southern Philippines. All five Philippine tarictics we're once considered a single species. It is declining due to habitat destruction, hunting and the illegal wildlife trade.
It is illegal to hunt, capture or possess these birds under Philippine Law RA 9147. [3]
Ebird described it as "A fairly large bird of lowland and foothill forest. Small for a hornbill. Bill fairly short with black bands, and with bare skin around the eyes and chin. Male has pale underparts and head with a black cheek, a pale buffy tail with a black tip, and pale blue facial skin. Female is entirely black with a buffy band through the center of the tail and darker blue facial skin. Rufous hornbill occurs in some of the same areas, but has a red bill. Samar Hornbill's voice is a short, medium-pitched honk, reminiscent of a squeaky toy, often given in rapid series." [4]
Formerly was once a single species. Visayan hornbill, Luzon hornbill, Samar hornbill and Mindoro hornbill. It is most similar to the Samar hornbill which it was again split from although some authorities believe in its treatment as a single species. It is differentiated from the Mindanao hornbill as it is smaller and the male has a rufous uppertail. Its call is also in a slightly higher frequency. [5] Diet is presumed to be similar to other hornbills namely fruit,seeds, insects and small mammals and reptiles. [5]
Two subspecies are recognized:
It is social and often seen in pairs or small groups up to 12 birds. These birds are noisy, emitting an incessant ta-rik-tik call, hence the name. Despite their noise they are difficult to find, being well camouflaged by the dense foliage. [6]
They are primarily frugivorous eating figs and berries but they are also known to eat insects, lizards and other small animals. Usually seen in pairs but can form flocks of up to 15 birds.
All hornbills are monogamous and mate for life.They are cavity nesters and rely on large dipterocarp trees for breeding. The female seals itself within the tree cavity and the male is in charge of gathering food for its mate and chicks. The male stores food in a gular pouch and regurgitates it to feed its mate and chicks. Cooperative breeding, wherein immature birds from previous seasons help out in feeding the female and chick has not been observed with this species so far. Among Philippine hornbills, it has only been recorded with the Rufous hornbill.
Among the tarictics, this species is one of the least studied but breeding habits believed to be similar to the better studied Luzon and Visayan hornbill. Clutch size is pressumed to be 2 to 3 eggs. Incubation period is slightly shorter than the Luzon hornbill at just 25 days. In captivity, chicks fledge within 47 to 54 days. [7] [8] [6]
Its natural habitats are tropical moist lowland forest with most records under 900 meters above sea level but with records of up to 1,450 meters above sea level.
This species has been assesed International Union for Conservation of Nature as Least-concern although this still includes the Samar hornbill as part of its assessment However, Mindanao and Basilan has gone extensive lowland deforestation on all islands in its range is the main threat. Most remaining lowland forest that is not afforded protection leaving it vulnerable to both legal and Illegal logging, conversion into farmlands through Slash-and-burn and mining. The basilanica sub-species is particularly threatened as there is only 230 hectares of primary forest left. Due to security situation on Basilan, It was only reconfirmed as extant in 2019.
This tarictic species complex is widely kept in captivity but due to the taxonomic reoragnization it is unknown if these birds are of pure descent.
This occurs in a few protected areas such as Mount Apo, Mount Kitanglad, Pasonanca Natural Park, Mount Kalatungan and Mount Malindang but actual protection from illegal logging, hunting and poaching are lax. [9]
The Visayan hornbill is a hornbill found in tropical moist lowland forests of the Philippines in the Western Visayas region which includes the islands of Panay, Negros and formerly as well as the island of Masbate, and formerly Ticao, in the Philippines. As is the case with all five Philippine tarictic hornbills, formerly considered to be just one species.It is declining due to habitat destruction, hunting and the illegal wildlife trade.
The pink-bellied imperial pigeon, also known as the zone-tailed pigeon, is found in the Philippines. It is a large and striking dove reaching sizes of up to 42cm long. The pink-bellied imperial pigeon is mostly dark green, with a pale gray head, an appropriately pink belly, and a brown, black, and gray pattern on its tail. Its eyes and eye ceres are red. Its natural habitat is tropical moist lowland forest. It is threatened by habitat loss.
The rufous hornbill, also known as the Philippine hornbill and locally as kalaw, is a large species of hornbill endemic to the Philippines. They are referred by locals as the "clock-of-the-mountains" due to its large booming call which typically occur of every hour. It occurs in moist tropical lowland forest. They are now considered to be a threatened species and its reasons for decline being habitat destruction, hunting and poaching for the illegal pet trade.

The writhed hornbill, also known as the Mindanao wrinkled hornbill, is a species of hornbill in the family Bucerotidae. It is endemic to primarily lowland forests on the Philippine islands of Mindanao, Dinagat and Camiguin Sur. It formerly included the Walden's hornbill as a subspecies, but unlike that species, both sexes of the writhed hornbill have orange-red throat and peri-ocular skin. The writhed hornbill is threatened by habitat loss and hunting.
The Luzon hornbill, sometimes called Luzon tarictic hornbill, is a species of hornbill in the family Bucerotidae. It is endemic to forests on Luzon and nearby islands in the northern Philippines. All five Philippine tarictics were once considered a single species. It is declining due to habitat destruction, hunting and the illegal wildlife trade.
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.

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.
