What is a Thunderbird?

Everything you need to know about Thunderbirds

The Thunderbird is unique to North America and is found most plentifully in Arizona. Taller than a man when full-grown, it has the power to create storms as it flies. The Thunderbird is so sensitive to supernatural danger that wands created with its feathers have been known to fire curses pre-emptively. One of the houses of Ilvermorny School of Witchcraft and Wizardry is named after the Thunderbird.
