Visayan Warty Pig

The Visayan warty pig takes its name from the three pairs of fleshy warts on a boar's face, which may help protect against rivals' tusks in fights. Boars also grow stiff, spiky hair. It lives in groups of four to six and eats mainly roots, tubers and fruit from the forest floor, and raids cultivated crops where its forest has been cleared (Wikipedia, general species account).

The pig once lived on six central Philippine islands but is believed to have disappeared from four of them, because about 95% of its natural habitat has been cleared. Only Negros and Panay have documented populations; the first photographs of the species in the wild came from camera traps in Northern Negros Natural Park in 2012. Piglets are born mostly in the dry season, from January to March. On this guide it is a species of Negros and Panay, and it is hard to see in the wild; conservation breeding programmes in the Philippines and in zoos abroad keep a reserve population (Wikipedia, citing published sources).
