Never Whistle at NightShane Hawk, Theodore C. Van Alst, Jr. et Collectif

Many Indigenous people believe that one should never whistle at night. This belief takes many forms: for instance, Native Hawaiians believe it summons the Hukai'po, the spirits of ancient warriors, Native Mexicans say it calls Lechuza, a witch that can transform into an owl. But what all these legends hold in common is the certainty that whistling at night can cause evil spirits to appear-and even follow you home.
