The Mindoro Tariktonic Hornbill ( Penelopides mindorensis ) is a species of bird in the hornbill family that is found in Southeast Asia.
The population of the Mindoro Tariktikhorn was classified in the IUCN Red List of Threatened Species in 2016 as " Endangered (EN) ".
Appearance
The Mindoro Tariktikhornbird is a relatively small hornbill with a body length of 45 centimeters. The male's tail accounts for an average of 20.3 centimeters, while the female's tail is slightly smaller at 19.4 centimeters. The beak of the male is on average 10 centimeters long, that of the female is slightly shorter with an average of 9 centimeters. The sex dimorphism in this species is so low that the sexes can hardly be distinguished in field observations. It is noticeably lower than that of other species of the Tarictic birds.
Appearance of the male
The head, neck and underside of the body are yellowish white. The ear covers and throat are black. The top of the body and wings are black with a metallic green sheen. The tail is brick-red, the individual rudder feathers each have black tips, which are largest on the outer rudder feathers.
The beak is black with a yellow tip and yellow stripes across the upper beak. The horn is a low beak ridge that ends on half of the beak. The bare skin around the eyes and the featherless throat patch are flesh-colored. The eyes are red-brown, the legs and feet are dark brown.
Features of the female and young birds
The adult females have a body plumage that is largely similar to that of the males. They are a bit smaller overall, the beak ridge is less developed. The featherless skin of the face is blue and the eyes light brown.
The young birds are similar to the adult birds, only the beak is a bit rougher overall.
Distribution area, habitat and endangerment.
The range of the Mindoro-Tariktikhornvogel is the island Mindoro . It is the only hornbill species found there.
The habitat of the Mindoro Tariktikhorn are evergreen primary forests of the lowlands, but it also occasionally migrates into secondary forests. The strong decline in forests on the Philippine island is the reason for the threat situation of this species. Today the island only has a forest area of 120 square kilometers. The remaining forests in the lowlands are heavily fragmented. The fact that the species is hunted unchanged also contributes to the endangerment of this species.
Way of life
The Mindoro Tariktikhorn is mostly observed in pairs, but less often in troops of up to four individuals. The Mindoro Hornbill looks for its food mainly at the edges of the forest.
The reproductive biology of this hornbill species has not yet been studied in detail.
