Genus Penelopides
Mindanao Hornbill - The Mindanao Tarictic Hornbill , sometimes shortened to Mindanao Hornbill, is a medium-small species of hornbill found in the canopy of rainforests on Mindanao, Dinagat, Siargao and Basilan in the southern Philippines. As is the case with all Philippine tarictic hornbills, it has been considered a subspecies of P. panini. Additionally, the Samar Tarictic Hornbill is often included as a subspecies of the Mindanao Tarictic Hornbill.
Sulawesi Hornbill - An Indonesian endemic, the Sulawesi Hornbill is distributed in the tropical lowland, swamps and primary forests of Sulawesi and nearby islands, from sea-level to altitude up to 1,100 metres. There are two subspecies of the Sulawesi Hornbill. The nominate subspecies, P. e. exarhatus, occurs in northern Sulawesi. The second subspecies, P. e. sanfordi is found in central, east and south Sulawesi, Buton and Muna Island.
Luzon Hornbill - The Luzon Tarictic Hornbill , sometimes shortened to Luzon Hornbill, is a species of hornbill in the Bucerotidae family. It is endemic to forests on Luzon and nearby islands in the northern Philippines. As is the case with all Philippine tarictic hornbills, it has been considered a subspecies of P. panini.
Mindoro Hornbill - The Mindoro Tarictic Hornbill , sometimes shortened to Mindoro Hornbill, is a species of hornbill in the Bucerotidae family. It is endemic to forests on Mindoro in the Philippines. As is the case with all Philippine tarictic hornbills, it has been 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, and primarily differ in the colour of the ocular ring .
Tarictic Hornbill - The adults show sexual dimorphism. The male has a creamy-white head and neck, a white upper chest, a reddish brown lower chest and uppertail-coverts, and a creamy-white buff tail with a broad black tip. The bill and casque are blackish; the former with yellowish ridges. The bare ocular skin is pinkish-white. The tail and bill of the female resemble that of the male, but otherwise the plumage of the female is black, and the ocular skin is blue.
Penelopides samarensis - The Samar Tarictic Hornbill , sometimes shortened to Samar Hornbill, is a species of hornbill in the Bucerotidae family. It is found in forests on the islands of Samar, Calicoan, Leyte and Bohol in the east-central Philippines. As is the case with all Philippine tarictic hornbills, it has been considered a subspecies of P. panini. Alternatively, it is considered a subspecies of P. affinis.
