In the Hindu epic Ramayana, Jatayu was the son of Aruna and brother of Sampati who is a demi-god and had the form of a bird, he was an old friend of Dasharath (Ram’s father). He tried to rescue Sita from Ravana when Ravan was on his way to Lanka after kidnapping Sita.
Jatayu fought valiantly with Ravana, but as Jatayu was very old Ravana defeated him without much difficulty. He cut Jatayu’s wings and injured him fatally. When Rama and Lakshmana came there searching for Sita, they found injured Jatayu. He was dying but still he informed Ram about his fight with Ravan and also informed them the direction in which Ravan had taken Sita.
Sampati was the elder brother of Jatayu and the son of Aruna. Jatayu and Sampati were two demigods having the form of birds. When young they used to compete as to who could fly higher. They fly higher and higher.
On one such occasion Jatayu flew so high that he was about to get seared by the sun. Realizing the danger of their situation, Sampati saved his Jatayu by spreading his own wings and thus shielding him from the hot flames.
As a result, Sampati himself got injured and lost his wings. Sampati lived wingless throughout the rest of his life. Sampati turned out to be crucial in Sita’s search later on in the Ramayana.
