The first day of the festival is called Kaag Tihar or Kwah Puja (worship of the corvids).[citation needed] Crows and ravens are worshiped by offerings of sweets and dishes placed on the roofs of houses. The cawing of crows and ravens symbolizes sadness and grief in Hinduism, so devotees offer crows and ravens food to avert grief and death in their homes. Tihar among Gorkhas represents the divine attachment between humans and other animals.
