Basic Information:
Yian Kut-kus are often the first true wyverns that many beginning hunters will face. Kut-kus mostly live in temperate zones keeping to the forests, where they are less seen by larger predators. For how commonly they are known to hunters, very few pay close attention to details. 

Locology:
As mentioned before, almost all Kut-kus live in temperate forest areas, avoiding extremely cold or hot places. They also are known to inhabit swamps, risking safety for the guarantee of food. They seldom come out into the open and keep among the trees and bushes to stay hidden from predators. Places like the Everwood, Forest and Hills, Swamps, or jungles are common places where Kut-kus are found.

Victology:
Kut-kus are one of the most versatile wyverns in terms of their diet. Though they are largely insectivores, feasting on Konchus, bnahabras, and other Neopterons, they often will eat small rodents as well berries and even honey. Though their diets largely depend on where they are and what food is actually available to them, after years of observation, I have found that their preferred diet later in life is actually determined while they are young and still being fed by their mothers.[1]

For example, mothers that bring mostly insects to feed its young will grow kut-kus that will almost exclusively hunt for insects, occasionally going for other resources when insects are scarce. This is thought to be so they don't compete against other kut-kus in the area for the same resources. So in theory, a maximum of three separate families of kut-kus can live in the same territory without much competition granted each family's prime source of food is mutually exclusive to the other families'. However, it is more likely the case that there are one or at most two families in a given territory as most kut-kus are acclimated to at least two sources of food, insects almost always being one of the two. 

Anatomy:
Yian kut-kus are comparatively smaller than other wyvern species ranging from about four and a half meters to up to twelve meters from head to tail. They are covered in orange-pinkish platings while their webbings are often colored blue. Their most notable feature is their large fan like ears and their underbitten beaks. Their lower beaks grow to be a about 1.5x up to double the size of their upper beak and have jutting edges that look like teeth. The anterior side of their neck is covered in a stretchable tissue for gulping down large food items, while their posterior side is covered in hard scales. The durability and size of the platings increase as you go down. The tail, while it may look thin, is actually quite tough and heavy to offset the weight of its beak and keep the wyvern balanced.

The bones of the Yian Kut-ku are more porous than other wyverns, making them very light. However, their lack of wing muscles don't allow them to flap for a very long time and aren't able to gain much vertical distance in their flight. However, due to their light weight, they are able to glide for a very long time. To make up for their lack of aerial prowess, kut-kus have developed very strong legs to help them run on ground and in fact have one of the strongest leg muscles relative to body weight. Their foot has strong talons that can be used to dig into the ground, though most prefer to use their beaks to do so. 

Physiology:
Kut-ku's most notable features are their large fan-like ears that span out when they are excited. The ears themselves are made from an erectile tissue covered with very thin hairs with numerous nerves running within the tissue. Regardless of whether or not their ears are up or not, the sheer number of hairs on its ears gives them an extraordinary sense of hearing. However, this also means that they are easily startled by loud noises and their ears are very sensitive to pain. Kut-kus rarely used their spread ears to actually hear better, as it makes their ears bigger and easier to hit. Their main purpose it to appear bigger and scare off and potential threats. When they become weak, they retract blood from their ears to protect it and pumps them into their legs and wings to prepare for retreat.

Kut-kus are one of the few creatures to evolve to have an underbite. Their beaks start developing while still in their eggs but only after they are hatched, do their beaks start to secrete keratin to harden and grow the beak. the majority of the secretion occur on the lower jaw, making them notably bigger and stronger than their upper beaks, which they use to dig into the ground, or hold and or crush objects. However, as a continuously growing beak can become a problem, Kut-kus have to sometimes intentionally wear down their own beaks to keep them from growing too heavy. The oral cavity created by the beak itself is actually quite large, able to hold up to two Konchus, or sometimes even their own young, albeit only when they are very young.

The anterior side of their neck are able to stretch out to accommodate for the large objects that the Kut-kus may swallow. Their throat muscles are able to expand and contract in a very precise manner that prevents them from choking when swallowing Konchus, their biggest food. Kut-kus also have Screamers, similar to those of the raptorial bird wyverns that gives them their loud squawks and cries.

Kut-ku's flame sacs, like many other fire spewing wyverns, e.g. Basarios, contain a pyrophoric substance that combusts when it comes in contact with the air. As the substance travels up its throat, it is coated in a fluid with low viscosity so the globule doesn't detonate until it breaks, usually after it leaves the mouth. 

Behavior:
Kut-kus are known to be born curious. Several days after their hatching they spend most of their time exploring their surrounding with their mouths, biting, chewing, and sometimes eating (for better or worse). To prevent prevent chicks from wandering too far or eating something that may be hurtful to the chick, Kut-ku mothers will spend time to build their nest walls high and digging away any foreign objects in the nest before she lays her eggs. For the first few weeks after chicks are born, mother kut-kus will actually hold chicks in their mouths when traveling from their nesting grounds to their foraging grounds. While they are out, chick follow their mother observing what she does when looking for food. Mothers prioritize food for their chicks before gathering food for themselves. During this time, most chicks are fed berries, small insects or honey, as their beaks aren't quite developed yet. When the mother senses a threat, she quickly signals to the chick as the run into her mouth for protection.

As the chicks grow older, they are fed nuts, roots, or even Konshus, though at this stage they are eaten in pieces, and not whole. They begin to develop their preferred diet and their beaks start to become more useful to them. When they are of adolescent age, they begin to practice territorial habits of gnawing on trees or even rocks to wear down their beaks as they begin to leave their nests. Once Kut-kus leave their nests, they wander around looking for food usually never sleeping in the same place twice. Only female Kut-kus will settle after mating with another and making a nest. 

When courting a female, male kut-kus will spread its ears and wings and do a sort of mating dance for the female. If the female is interested, she will return the dance and, soon after, mate. However, this process is quite fragile, as other kut-kus, both male and female can interrupt this ritual and start a duel. When the courting ritual is interrupted, the interrupting male will challenge the dancing male and try to fight the male off by either scaring it off with its size or by combat. The same can happen when a female returns the dance to the male. However, if at any time the ritual was interrupted, the victor will almost always get the mate. In other words, if the male is interrupted, the victor will get the female without a return dance required. If a female was interrupted, the victor will get the male without having to dance. 

After a female has been courted, she takes time to gather materials for her nest and it is during this time she develops her feeding territory. As mentioned before up to three families can live in the same feeding territory, but if one mother happens to see another feeding on the same resources, there is often a standoff until one of them back down, at which territorial boundaries are set. It is during this time mothers will eat the most to fatten up while she has to take care of her eggs.

Once a female lays her eggs, up to three, she seldom leaves the nest and becomes extremely aggressive to anything that wanders too close, even leaves that fall too close to the nest. She will on occasion leave the nest for brief moments to gather food, but she never leaves far enough where she won't be able to see her eggs. 

Ecology:
It is often best to think of Kut-kus as closer to birds than actual wyverns in terms of their role in the eco system. Many Kut-kus are responsible for spreading seeds through their droppings and keeping other herbivores safe from bigger prey. In a way they are guardians of medium sized herbivores that dwell in the temperate forests or jungle zones. Many herbivores seem to largely ignore Kut-kus so as long as their ears aren't up. Sometimes, young Kut-kus wil approach mosswines or kelbis lightly pecking at them with their beaks if they get a chance, which will usually merit a stern grunt. However, Kut-kus seem to know they aren't a threat to them and learn to coexist with them. 

When confronted with danger, Kut-kus will spread their ears and wings, lift their heads up high to appear a lot larger than they are, and squawk loudly to hopefully scare potential threats. When that doesn't work, Kut-kus fight using their strong beaks to peck at adversaries, use their thick tails to whack away foes, or burn them with their flame globules. When angered, their flame sacs begin to act up in response and as a result, many hunters will notice the Kut-kus seem to be breathing fire as the substance comes in contact with the air. In some interesting cases, Kut-kus have learned to use Konchu's hard shells and will dig up and throw rolled up konchu's as a defense mechanism. Of course when all else fails, they use their strong legs to run away and fast.

Kut-kus are occasional preys of Rathalos, Rathians, Khezus, Plesioths, Najaralas, Deviljhos and other carnivores wyverns that venture into the temperate forests and jungle. Carapaceons such as hermitaurs and ceanataurs, and small carnivores like velocipreys will feed off the remains of a Kut-ku if available. A strong pack of velociprey led by a Velocidrome or two may attack Kut-kus on occasion and can succeed from time to time, but usually will end with the Kut-ku getting away, thanks to its speed.

Subspecies Variants
Blue Yian Kut-kus are a rare subspecies that even I don't have much information about. I haven't seen any blue Yian Kut-ku chicks and neither have I seen blue Kut kus mate or lay eggs which leads me to believe that Blue Tian Kut-kus are just normal Yian Kut-kus that have survived for a very long period of time. The blue variants tend to be smaller but more stronger and aggressive than their pink counterparts, but are very similar otherwise. Some Blue Kut-kus are known to grow out their lower beak to unusual proportions to enforce their beak strength and digging abilities. Blues with this beak variant have been seen to dig up small holes that act like pitfalls both for prey and threats. Additionally, the saliva of a blue Yian kut-ku have an even lower viscosity and higher cohesion such that their fire globules may even bounce a couple of times along the ground before igniting. 

Human Uses:
All in all Kut-kus are mostly used for either armor or food. As mentioned before Kut-kus are often the "gateway wyvern" for many starting hunters as armor made from Kut-kus are fairly durable and fire-resistant, and are often captured to be used in the arena for beginners to practice on.

Kut-ku legs and wing meats are quite good and their tail bones are often used as stocks for soup as Kut-kus are fairly abundant in numbers. Meat from a blue-kut-ku will often fetch a higher price as they are harder to come by. However, the most expensive cut of the Yian Kut-ku is their ears. Some cooks may tear the ear into strips and deep fry them while others might use them in a salad or use them as a stock for soup, as it is a rather versatile ingredient.

Their study beaks are often used in making armor but it is also a favorite of farmers who like to use their lower beaks as hoes and their upper beaks as shovels. Other lay people may use them as bowls, decorative or otherwise. Their ears are a commodity that many people like to use for different things. Some use them for decoration while others turn them into fans, while others like using them as a wrapping material or the like. Their screamers are very useful for hunters as they are used to make sonic bombs, a small ball that emit a very loud sound when broken.

Hunters Notes:
- Yian Kut-kus, though fast, are often clumsy and fall over in an attempt to charge at you.
- Use Sonic bombs to temporarily daze them, but be careful as it will anger them.
- Their flame globules will stick to you and continue to burn you if you let it. Roll in the dirt or water to put it out.
- If they retract their ears, it's a sign they are getting weak, and getting ready to run.

Research and Observations:
[1]Observation 1
Females kut-kus with eggs in the wild were kept under close observation for several months by several specialized hunters. Each mother was pick out such that each mother's main food source was mutually exclusive from the others. During the gestation period, it was observed that their feeding territory overlapped quite a bit. Encounters were observed to be non hostile until after the eggs were laid. During the incubation period, the most that occurred during encounters were mild hissing just as a warning. This continued until the chicks hatched, at which point the mothers mellowed out. Chicks were seen approaching other families without much aggression either. It is under speculation that this is allowed to widen a chick's awareness of what's edible by observing other families foraging habits. The only time aggression is shown between families is when one starts to take resources of another's family.
So I looked back at my gallery and noticed it's been seven years since I did my last ecology. Hopefully this ecology on everyone's favorite chicken wyvern is to your pleasing. I noticed it's also a bit longer than my ecologies from 7 years ago. Hope that doesn't deter anyone lol. Cheers.

Special thanks to DarkmaneTheWerewolf for refering me to a primary source where Kut-ku chicks are seen running into their mother's mouth for protection.

I can never decide whether I find Kut-Kus butt ugly or kinda derpy in an adorable way...

Yian Garuga is just pure Hell '_'

lol, kut-ku used to scare the living crap out of me when i first started playing Monster Hunter Freedom 1. Like  Rathalos was a cakewalk compared to the first Kut-ku and then I saw the Yian Garuga which was basically a scarier very of kut-ku.

I love how extense is this ecology! Well explained and so interesing but now I want what will you do for the garuga ecology. I don't know how active are you but I will wait patiently for the garuga ecology...But if you are interesed can I comment to you some thoughts than I have about garuga ?

And about kut-ku...Do you think than kut-ku and garuga eat whole konchus because konchus have some sustance than increase the hardness of some structures of their bodies? I thought this because than I know kut-ku and garuga are the only monster than eat whole konchus but also are the only bird wyverns than have shells, and is well knowed the big defense of the konchu's shells. Is just an idea but I think that is why the kut-ku/garuga shells

That sounds about right, just like how the calcium in your milk makes your bones stronger, I imagine the chitin and other minerals in the shells of the konchus contribute to the hardness of the kut-ku's shells.
