Many indigenous people believe that one should never whistle at night. This belief ranges far and wide and takes many forms- for instance, Native Hawaiians believe it summons the Hukai'po, the spirits of ancient warriors, and Native Mexicans say it calls Lechuza, a witch that can transform into an owl and snatch the foolish whistlers in the dark. 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.
