Boreolus

Boreolus are Flying Wyverns introduced in Monster Hunter Origins.

Physiology
Boreolus are large, light gray-colored wyverns. They have a conical head with a black beak-like mouth, and sport a large, bony neck frill with a wavy margin and a sky blue-colored dewlap that they can extend and retract. They have large wings in comparison to the rest of their body. The wings have sky blue webbing with thin, white, wispy stripes. They have a long, thin tail tipped with a fleshy whirl. Their feet have three sharp claws and one dewclaw.

Abilities
Boreolus flap their wings to create strong winds that blow away enemies. They can also whip up small twisters with their wings. They can even unleash a powerful vortex of air from their mouth.

Taxonomy

 * Order: Saurischia
 * Suborder: Wyvern Feet
 * Superfamily: Strong Wind Wyvern
 * Family: Boreo

Habitat Range
Boreolus are known to inhabit the Arid Field, Placid Meadow, Sandy Shore, and Skyscraper Mountains.

Ecological Niche
Boreolus are airborne predators, knocking prey out of the sky with the winds they generate. They generally feed on insects, birds, and smaller wyverns such as Morphosis and Pipistilio. They occasionally target terrestrial prey such as Termitaur and Aterux. However, these wyverns coexist with other predators like Davolius and Sigmohrias, so they keep an eye out for them.

Biological Adaptations
Boreolus possess a large wingspan in comparison to the rest of its body. Their large wings make them capable fliers, able to perform difficult maneuvers and fly incredibly fast (albeit not as fast as Valstrax for obvious reasons). Their large wings also act as fans, as they are able to generate strong wings simply by flapping. The winds they can produce have been recorded to go as fast as 47–54 mph, or 75–88 km/h. They can also create small twisters with their wings. How they do so is unknown, but it may have something to do with the shape of their wings and how they move them. They can even produce a powerful vortex of air akin to an Akantor's sonic blast, the difference being that a Boreolus's vortex is not as powerful and has less range. They sport a sharp, beak-like that rips flesh off of prey.

Behavior
Boreolus are very territorial, prowling the skies for prey and trespassers.
