Yian Kut-Ku Ecology

Disclaimer:: This is merely a plausible explanation for the monster(s) in this article, and should not be considered canon.

Taxonomy
The "poster child" of the Bird Wyvern family, Yian Kut-Ku is easily the most recognizable of all bird wyverns. Bird Wyverns have lightweight frames, hollow bones, and typicially have large beaks. They are very fast on ground, and competent flyers in the air. Yian Kut-Ku closely resembles its greater cousin "Yian Garuga"

Habitat Range
Yian Kut-Ku often nest in the jungle, favoring its warm climate and abundant small prey. This has aptly earned the creature the title of "Jungle Menace." Yian Kut-Ku are also frequently seen in the forest & hills as well as the swmps. This would indicate that Kut-Ku favor warmer climates. Kut-Ku share many of the same nesting sights as larger wyvern such as Rathalos, and are often forced from their homes because of this. This would explain why Yian Kut-Ku are often seen wandering aimlessly and display little territorial nature.

Ecological Niche
Kut-Ku is very small for a wyvern. In fact on occasion a Super small breed has been spotted. though these may in fact be Young Kut-Ku forced from the nest. Because of it's size the creature cannot handle large predators and in fact may become food for larger wyverns. Kut-Ku isn't the most graceful hunter either; when charging prey it uses a so called (Chicken run) in which it runs at the prey or enemy and launches fire balls from left to right. Not terriblely useful for agile creatures. Often it must battle for it's food as packs of "Raptor-Prey" will makes it's day diffucult. Velicprey packs will often ambush a Kut-Ku who's killed a monster and attempt to steal it's food. Not that the Kut Ku will go down or back off with out a fight. The creature has a roar, with which to frighten other creatures and the will make good use of its abilty to spit weak fire balls.

Biological Adaptations
Kut-Ku can fly, a major advantage over lesser Prey Monsters. It's not a great flyer when compared to other wyverns though. Kut-Ku can hurl large fireballs, and although these are effective at killing weak prey such as Kelbi, they do little to deter larger wyvern threats. Yian Kut-Ku possesses a very large and sturdy beak used to crush the bones of its prey and aids in tearing off large chunks of flesh, but contains no teeth. Due to its inability to chew its food, Yian Kut Ku must swallow several large stones to aid in its digestion by pulzerizing food in the gizzard.

Behavior
A somewhat tempermental wyvern. Yian Kut-Ku will attack most hunters on sight, although this is often not a wise decision. Yian Kut-Ku is reletively low on the wyverian totem pole, and because of this it's bark is often worse than its bite. Kut-Ku often try to appear bigger than they are by spreading their wings and perking their ears, this behavior is often accompanied by a loud roar. When facing larger wyvern, Kut-Ku will often flee before they damage their fragile wings.
