Dyuragaura Ecology

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

Taxonomy
Dyuragaua is classified as a Pseudowyvern, a lesser class inside the bigger Flying Wyvern classification. It's loosely related to Tigrex, Pariapuria, Barioth and similar monsters.

Habitat Range
This dangerous, mongoose like pseudo-wyvern was first found in the Nest Hole but has also been found in the Highland.

Ecological Niche
Dyuragaua is likely a super predator and a rather intelligent one much like many other wyverns. They prefer to avoid competition which probably explains how it avoided human contact for so long in the Nest Hole at the Tower.

Biological Adaptations
Dyuragaua has primarily green scales to camoflage itself in the area around the tower. It has small spikes to use for intimidation ,or for attracting potential mates. Its claws are used to climb up walls, and to grasp its prey. Its teeth are its secondary weapons, which are straight and are only used for puncturing, not for holding onto prey. It has a great sense of smell like other psuedo-wyverns.

Behavior
Dyuragaua is a powerful predator in the tower. It leaves its nest hole to hunt,and returns after catching and eating prey to rest. It is very territorial,due to its high metabolism and source of prey, and will fight for its land. As seen when hunters stumble into the nest hole. Dyuragaua will fiercely defend its own young like any wyvern. It is yet unknown if dyuragaua will pair up to raise their young, but it is unlikely due to their need for enormous quantities of food. As confrontations between other wyverns (rathalos) haven't been documented. It never ventures to the top of the tower because of the threat of an encounter with elder dragons that reside at the top of the tower. It likely uses its claws to deal a slash at its victim, but if its victim doesn't die it will use its jaws to kill it. If its prey is too far away, it will blast an ice attack to stun it.
