Its all about CROW an important Bird according to  Hindu Epics....................................
 
There are two important stories in Puranas regarding the origin of crows. Crows are important Hinduism because one of the unique rituals followed in Hindu tradition during Shradh is offering food to crows. As per Agni Purana, crows in the world were born from Kaki, the daughter of Sage Kashyap and Tamra.

Another story of origin of crows is mentioned in the Shiva Purana. King of Kashi had a daughter named Kalavati – she was an ardent devotee of Shiva and always chanted the Shiva Panchakshara Mantra. She was married to Dasarha, King of Mathura. When Dasarha touched Kalavati intense heat was produced and this burned the hands of the king.

On enquiry it was found the Dasarha was a sinner and was leading an Adharmic life.

Kalavati took Dasaraha to Sage Garga, who purified him with mantras. Through the power of the mantras, sins from Dasaraha came out in the form of crows.
 
One of the unique rituals followed during Shradh is offering food to crows. A part of the food that is cooked for ancestors, dead parents and relatives are offered to crows while performing Shradh, Tarpan and Pinda Daan. This is based on the belief that food offered to crows directly reach ancestors in their world.

It is believed that food offerings to crows began in the Treta Yuga and it was Sri Ram who blessed crows to receive food offerings for ancestors.

Once during his exile period Sri Ram noticed that a crow was troubling Mata Sita. The crow started hurting Sita by pecking on her head. Sri Ram to get rid of the crow took hay and used it as an arrow and shot at the crow.

The hay struck on an eye of the crow and it fell down.

Suddenly the crow changed into a human being. The crow was Jayant, son of Indra, who due to a curse had become a crow.WithSri Ram shooting the crow down, it was relieved of the curse.

Sri Ram then forgave Jayant for attacking Mata Sita and gave the blessing that food offered to crows will reach ancestors.
