Before the advent of Hawaii human role of predators and herbivores in the ecosystem of the islands played birds. With the arrival of man on the islands there were a variety of mammals, and it has led to irreversible changes in the ecosystem and the directions of its evolution after humans. Introduced mammals occupied a dominant position in the ecosystem, and only a few species of birds able to compete with them. In Neocene live on islands large birds: Hawaiian herbivorous wild geese (Moanser sylvestris) and kuahana (Machairopterus kuahana) - flightless bird of prey; but they share with multiple islands of mammals, including carnivores. The dominant group of carnivorous mammals are manusty - descendants of the small Asian mongoose (Herpestes javanicus). Among them are large feline counterparts, climingb species like martens and smaller burrowing forms resembling weasels and stoats. One of the most common predators in the mountainous forests of the island of Hawaii is Kouame - ground and poludrevesny predator, weighing about 10 kg. It is an active predator that can kill prey that weighs more than him (hence the name in honor of a demon-killer of native mythology).
Kouame physique resembles a large cat with a long tail-rocker. He has a flexible neck, small head with a graceful small rounded ears, short muzzle and powerful jaws that can be opened wide. Carnivorous teeth greatly enlarged, pointed, with a strong cutting edge. Nevtyazhnye claws, sharp, slightly curved. The animal walks and runs easily on the ground, can climb on the rocks and a sloping tree trunks.
Coat coloring is sand-yellow with a dark stripe on the back of the head to the end of the tail and large dark strokes on the sides. Feet in black "stockings" to the elbows and knees. Above the eyes of a pair of white spots. Males and females do not differ color, but male is larger than the female and weighs about 1 kg more.
Kouame is a generalist predator and the largest predator in the mountain forests. His favorite tactic of hunting - an attack on prey from ambush, often on top, with a stone or a tree branch. When attacking Kouame tries to bring down prey with feet hit the whole body and immobilize it, bite the spine. Less beast pursues prey on the ground, but only able to run fast for short distances. The usual prey of this animal are large rodents, ground birds and young Hawaiian forest geese. If there is a major production, Kouame can catch lizards and small rodents, and insects.
This predator lives in pairs; male and female form a family for several years and together grow offspring. Each pair of jointly controlled territory and marks its borders musk secretions. During the mating season the female musk highlight acquire specific pungent odor that attracts males. If the territory of the couple comes to single male animals couple usually drives it together. On the territory of a single females between males flare brutal battle, during which opponents strongly tearing each other's shoulders and front legs.
Den is a hollow trunk of a tree hole or a natural cave. 2 times a year the female gives birth to 4-5 cubs. Newborn cubs are cover
ed with dark hair, blind and deaf. They begin to see and hear at the end of the 1st week of life, and in the months of age they began to lighten the background color of the coat. At the age of 4 months, the young animals are already accompany parents on the hunt.
