Some birds are thought to possess supernatural powers. The sorokochoâ€™, or Masked Tityra (Tityra semifasciata), is said to have specific healing abilities. For example, to cure warts somewhere on oneâ€™s body, that person must find a group of these Masked Tityra singing in a tree. By dancing enthusiastically along with the displaying birds, this will excite the birds to sing and move even more, thus causing oneâ€™s warts to disappear within a few weeks.
Châ€˜ol say that there is a prohibition against killing a pegre (a Spanish or Spanicized term), or Masked Tityra (Tityra semifasciata). If you shoot one, they say you will get warts on your body as a punishment.
