Yian Kut-Ku

A Flying Dragon with the trademark frill necked ears. They are rather small sized as far as Flying Wyverns go. They inhabit forests, hills, jungles, volcanoes, and other similar environments. Because of their thin legs, giant beaks, and the way they peck the ground, they are often called “Monster Birds”.

Docile by nature, they usually subsist on bugs and nuts found in the ground. They are belligerent towards Hunters, and use their Fire Fluid and peck attack to defend their territory. When they become endangered they run away immediately, revealing their tender nature.

Their abilities are lower than normal, and they leave themselves open to attack a lot. They possess the Anger and Area Movement that are fundamental to Flying Wyverns. They are in comparatively stronger then small-medium sized monsters. Yian Kut-Kus are often the first Flying Dragon target for many Hunters.

Their weak point is explosive sounds, but...

As one can guess from their highly developed ears, Yian Kut-Kus are Flying Wyverns with great hearing. Their ears are effective for hearing prey and enemies outside their range of sight, but because of their over-sensitivity they are also vulnerable to explosive sounds. There are several ways to expose them to explosive sounds, the most common are sound bombs, barrel bombs, and armor-piercing bullets. Dizzied Yian Kut-Kus are completely defenseless, and one can attack them freely. But, the Yian Kut-Ku will become Angry once their dizziness wears off. Also, an angered Yian Kut-Ku no longer is susceptible to explosive sounds.

They have a sub-species known as the Blue Yian Kut-Ku and their "evil" counterparts the Yian Garuga.
