Their shrill voices are only intelligible to other pixies. They bear live young. (CS6, FB). According to Fantastic Beasts and Where to Find Them, pixies delight in “in tricks and practical jokes. Though pixies can fly, and imps cannot, the two are often confused due to their similar height and sense of humor (FB).

Commentary
Notes
In folklore, pixies, (or piksies, as they are also called), are typically found in Devon and Cornwall. They appear in various forms and are described as fond of music and dancing. Typically, they are helpful creatures who help with housework, and are even sometimes credited with creating clotted cream on Dartmoor for deserving housewives. On the other hand, pixies are just as likely to eat all the cream, since they’re mischievous and fond of tricks. They will confuse travellers on the moors and have been accused of stealing children. Pixies wear green clothing to better blend in with their surroundings. They have slanted eyes and pointed ears, but they definitely aren’t blue-skinned. They resemble wildly-dressed humans, not the electric blue imps seen in the Harry Potter books or film. --SVA
