What are Bird Wyverns?

Bird Wyverns (Japanese 鳥竜種) are a class of monsters introduced in the first generation. They are a small to medium sized class that includes Flying Wyverns with slender bodies that are bipedal and, in some cases, either have wings or lack wings.

List of Monsters in this Class


  • They get the title, Round Bird, due to their round shape.
  • Gargwa can be found living in Misty Peaks, Ancestral Steppe, Everwood, and Forest and Hills/Verdant Hills.
  • Gargwa look a lot like birds but they aren't birds, Gargwa are actually Bird Wyverns. They actually have the same common ancestor as other Bird Wyverns such as Velociprey.
  • Despite being Bird Wyverns Gargwa are quite cowardly and timid compared to other Bird Wyverns. At one time they were going to be put into the Herbivore classification due to their cowardly and timid personality, however, this was changed because they were found to be omnivores and do to how similar their skeleton is to some other Bird Wyverns.
    • Gargwa feed on grass, Thunderbugs, and other insects.
  • Gargwa are highly valued by people for a multitude of reasons. Many are domesticated for some type of work by people or just for their meat and eggs. **Domestic Gargwa are well-known for pulling carts. Though they can't carry as many things in a cart as an Aptonoth or Popo can, they make up for with their great speed. This speed can also be dangerous due to them being known to knock people off carts if encountered with danger.
  • Their feathers are highly valued for clothing.
  • Their beak is made of an insulating material that prevents them from being shocked by their favorite prey, Thunderbugs. This makes them the natural predator of the Thunderbugs.
  • It is unknown how a Garwga is able to lay a golden egg.
  • Gargwa droppings can be dried and powdered for medicinal use.
  • If startled by a predator or something else, Garwga will either leave behind droppings or an egg though some Garwga will try to fight back.

Velociprey and Velocidrome

  • Velociprey are pretty much a beginner hunter's first challenge when hunting monsters.
  • Velociprey packs are quite adaptable and can be found living in areas with the other breeds of Runner Wyverns. Some may even become the other Runner Wyverns species like Giaprey. Velociprey packs in the Everwood are a rare sight.
  • Their colors are used as a warning to potential predators.
  • From their highly developed brains, Velociprey can come up with a hunting plan quite quickly. The Velociprey will use a range of calls to talk to each other in order to cooperate properly. They usually surround prey, giving it little ways to escape, and attack by using their foot claws and hand claws. If their is a large pack, they can take down prey bigger than young Aptonoth.
    • Occasionally, Velociprey packs are known to raid villages for food and will sometimes raid villages if food is scarce.

  • Their favorite prey item is Apceros and Aptonoth.
    • Its asked for merchants and travelers to be wary while traveling with Aptonoth do to the Genprey's taste for Aptonoth.

Giaprey and Giadrome

  • At first Giaprey were thought to be Albino Velociprey due to them looking very similar to them instead with white scales and from them being found along side Velociprey.

  • Despite being small, Jaggi are quite aggressive and will relentlessly attack threats, even when their alone, though they will usually back down when faced with a bigger more dangerous threat, either leaving or waiting for the threat to leave. It is known that Jaggi are bold enough to attack large predatory monsters like some Flying Wyvern species.
  • When alone, Jaggi will just feed on small fish and other small prey. In a pack, they will hunt down Aptonoth by using various hunting strategies. They will run around prey to confuse it and use their speed to their advantage. While surrounding the prey, they attack the prey from its blind spots, making the prey bleed.
  • Each member in the Jaggi pack play some specific role in the pack. The role of the Jaggi is to patrol the distant outskirts of the territory and to hunt down prey for the rest of the pack while away from the main territory. The role of the Jaggia is to take care of the young and to guard the main territory's nest. The role of the Great Jaggi is to be the leader and protect the territory.
    • Occasionally, Jaggi can cause problems near villages due to them being away from the main territory.
  • Great Jaggi always eat first, Jaggia always eat second, and Jaggi always eat last.
  • Jaggi and Jaggia can be pushed away by using torches. This is how some villages usually get rid of them when they become a pest.
  • Jaggia are larger and stronger than Jaggi though aren't as agile as Jaggi.
  • There are fewer Jaggia in a Jaggi pack than there are Jaggi.
  • When Jaggi reach a certain age, they will leave the pack. Most of the Jaggi will die after leaving the pack and some will become the powerful Great Jaggi.

It is unknown how they are able to do this, although current theories suggest that the Qurupeco's cries while it dances may be capable of accelerating the metabolism of whatever hears them.
  • The mucus Qurupeco spits is highly flammable and can explode from a single spark.
  • The Qurupeco chicks have fully developed vocal organs from the time they hatch, which can be dangerous for them as they may unwittingly attract predators to them with their calls.

  • Due to its great experience in fighting, the Hunter's Guild only allows hunters with special permits to hunt down a Deadeye Yian Garuga.
