Thunderbird

The Thunderbird is a creature of legends, though very much real. Taking the form of a variety of different birds, they appear to cause changes in the weather wherever they go. Most cause storms which they delight in, from which they take their name. Fast and tempestuous creatures, a Thunderbird is many people wish they will go their lives not seeing.

Habitat
Thunderbirds prefer to live above the world and make their nests in such places like the tops of trees, or on rocks on the higher parts of mountains. They build nests from driftwood or other debris they find from storms, taking the effort to fly them up to where they are building their nests. Why they do so are unknown, but it seems their very nature is imbued with the tempest.

Biology
Thunderbirds tend to resemble a variety of birds, appearing slightly larger than the bird they resemble. Most commonly they resemble an Owl, a Crow, a Falcon, an Eagle, or a Hawk, but they can appear as any bird, even the outlandish ones. Asides the overall slightly larger size, there is nothing to differentiate them from looks alone.

Sociology
Thunderbirds are mostly solitary creatures, though they will occasionally hunt with their mate or children. They have small family units, never exceeding a handful of Thunderbirds. Too many Thunderbirds in one area will quickly create conflicting weather conditions leading to a localized disaster and often the deaths of the Thunderbirds present.

Thunderbirds are notorious for hunting animals far larger and more dangerous for themselves, even though they are omnivores. They will attack boar, wolves, even humans if they situation presents it, and are not without their own tricks. Asides from changing the weather, they can flap their wings to direct thunder during a thunderstorm, giving them a huge advantage against any foe. Even so, they are still birds at their core.

Trivia
A Thunderbird is oft spoken of in villages and towns, a harbinger of bad weather and floods to come. More than that, they seem to be right, as they will appear before a natural storm and stay throughout it for no better reason to enjoy the tempest itself. Most Thunderbirds are thus attacked as soon as they are identified, lest they bring misfortune to all present.
